<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Device Settings

The following settings are available on the Settings tab of a device.

i_round_blueWe recommend that you define as many settings as possible in the root group settings so that you can inherit them to all other objects in the object hierarchy.

For device settings, you can also use multi-edit. This enables you to change the settings of many devices at the same time.

i_square_cyanFor more information, see section Multi-Edit.

i_round_blueThis documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.

Setting

Description

Device Name

Enter a name to identify the device. By default, PRTG shows this name in the device tree, as well as in alarms, logs, notifications, reports, maps, libraries, and tickets.

i_round_blueIf the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?

Monitoring Status

Select the monitoring status of the device:

  • Started: Monitor the device.
  • Paused: Pause monitoring for the device. All sensors on the device are in the Paused status until you change this setting.

IP Version

Select the IP protocol that PRTG uses to connect to the device:

  • IPv4: Use IP version 4 for all requests to the device.
  • IPv6: Use IP version 6 for all requests to the device.

i_round_blueThe setting is valid for all sensors that you create on the device.

IPv4 Address/DNS Name

This setting is only visible if you select IPv4 above. Enter the IP address or Domain Name System (DNS) name for the device. Most sensors that you create on this device inherit this setting and try to connect to this address for monitoring.

i_round_blueSome sensors have their own setting for the IP address/DNS name to which they connect.

IPv6 Address/DNS Name

This setting is only visible if you select IPv6 above. Enter the IP address or Domain Name System (DNS) name for the device. Most sensors that you create on this device inherit this setting and try to connect to this address for monitoring.

i_round_blueSome sensors have their own setting for the IP address/DNS name to which they connect.

Parent Tags

Shows tags that this device inherits from its parent group and its parent probe.

i_round_blueThis setting is for your information only. You cannot change it.

Tags

Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.

i_round_blueWe recommend that you use the default value. You can also add additional tags.

i_round_blueIt is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).

i_round_blueFor performance reasons, it can take some minutes until you can filter for new tags that you added.

Priority

Select a priority for the device. This setting determines the position of the group in lists. The highest priority is at the top of a list. You can choose from the lowest priority (i_priority_1) to the highest priority (i_priority_5).

Setting

Description

Auto-Discovery Level

Select the level of detail for the auto-discovery:

  • No auto-discovery: Select this option if you only want to manually create devices and sensors.
  • Standard auto-discovery (recommended): Create a set of standard sensors for standard monitoring. This option works fine for most installations.
  • Detailed auto-discovery: Create all standard sensors and additional sensors from detailed variants of device templates. As a result, you might get many sensors. This option is suitable for small network segments and whenever you want to monitor the maximum number of sensors available.
  • Auto-discovery with specific device templates: Customize the auto-discovery and select or combine standard, detailed, and custom device templates. Select one or more templates from the Device Templates list.

i_round_blueAuto-discoveries can be resource intensive. They are primarily intended for devices on the same network as your probes.

Schedule

Select when PRTG runs the auto-discovery:

  • Once: Run the auto-discovery only once. PRTG adds new devices and sensors once. If you select this option, you must manually start the auto-discovery.
  • Hourly: Run the auto-discovery for new devices and sensors every 60 minutes.
    i_round_redUse this option with caution. Frequent auto-discoveries might cause performance issues, in particular when PRTG scans large network segments every hour.
  • Daily: Run the auto-discovery for new devices and sensors every 24 hours. The first auto-discovery runs immediately. All other discoveries start at the time that you define in the Monitoring settings, section Auto-Discovery.
  • Weekly: Run the auto-discovery for new devices and sensors every 7 days. The first auto-discovery runs immediately. All other discoveries start at the time that you define in the Monitoring settings, section Auto-Discovery.

i_round_blueFor performance reasons, PRTG sets Schedule to Once on all devices that the scheduled auto-discovery creates.

Device Templates

This setting is only visible if you select Auto-discovery with specific device templates above. Select one or more device templates by enabling a check box in front of the template name.

i_round_blueYou can also select all items or cancel the selection by using the check box in the table header.

Setting

Description

Location (for Geo Maps)

If you want to use Geo Maps, enter a location in the first line. Geographical maps then display objects like devices or groups with a status icon using a color code similar to the sensor status icons (green–yellow–orange–red). You can enter a full postal address, city and country only, or latitude and longitude. It is possible to enter any text before, between, and after the coordinates, as PRTG automatically parses latitude and longitude, for example, enter 49.452778 11.077778, or enter 49.452778 any 11.077778 text.

A minus sign (-) in the first line hides an object from a geographical map. In this case, you can enter location information in line two and following.

You can define a specific label for each location. Enter a string denoting the label in the first line and provide the coordinates in the second line. This geographical marker then shows the object with the label in the geographical map.

i_round_blueThe preview map always has a road map layout regardless of the map layout you set in User Interface.

i_round_blueBy default, PRTG automatically uses this setting for all SSH sensors unless you define a different port number in the sensor settings.

SSH Rights Elevation

Select the rights that you want to use to run the command on the target system:

  • Run the command as the connecting user (default): Use the rights of the user who establishes the SSH connection.
  • Run the command as a different user using 'sudo' (with password): Use the rights of a different user with a password required for sudo to run commands on the target system, for example, as a root user.
  • Run the command as a different user using 'sudo' (without password): Use the rights of a different user without a password required for sudo to run commands on the target system, for example, as a root user.
  • Run the command as a different user using 'su': Use the rights of a different user with su to run commands on the target system.

Target System User Name

This setting is only visible if you select an option that includes sudo or su above. Enter a user name to run the specified command on the target system as a different user than the root user. If you leave this field empty, you run the command as a root user. Make sure that you set the Linux password even if you use a public key or a private key for authentication. This is not necessary if the user is allowed to run the command without a password.

Password

This setting is only visible if you select an option that includes sudo or su with password above. Enter the password to run the sudo command or the su command.

SSH Connection Mode

Select the connection mode that you want to use to access data with SSH sensors:

  • Default (recommended): This is the default connection mode for SSH sensors. It provides the best performance and security.
  • Compatibility mode (deprecated): Use this only if the default connection mode does not work on the target system. The compatibility mode is the connection mode that PRTG used in previous versions and it is deprecated.

i_round_redWe strongly recommend that you use the default connection mode.

i_round_blueYou can also individually select the connection mode for each SSH sensor in the sensor settings.

Credentials for VMware/XenServer

Password

Enter the password for access to VMware ESXi, vCenter Server, or Citrix XenServer. Usually, you use credentials with administrator rights.

i_round_blueSingle sign-on (SSO) passwords for vSphere do not support special characters. For details, see the VMware sensors sections.

VMware Protocol

Select the protocol for the connection to VMware ESXi, vCenter Server, or Citrix XenServer:

  • HTTPS (recommended): Use a Secure Sockets Layer (SSL)/Transport Layer Security (TLS) secured connection.
  • HTTP: Use an unsecure connection.

Session Handling

Select if you want to reuse a session for VMware sensors:

  • Reuse a session for multiple scans (recommended): Select this option if you want a VMware sensor to reuse a single session for multiple sensor scans to query data. With this option, the sensor does not need to log in and out for each sensor scan. We recommend that you use this option because it reduces network load and log entries on the target device. This can increase performance.
  • Create a new session for each scan: If you select this option, PRTG does not reuse a session and a VMware sensor has to log in and out for each sensor scan. This can decrease performance.

Credentials for SNMP Devices

Click b_inherited_enabled to interrupt the inheritance.

i_round_blueThe settings you define in this section apply to the following sensors:

Credentials for SNMP Devices

Credentials for SNMP Devices

Setting

Description

SNMP Version

Select the Simple Network Management Protocol (SNMP) version for the connection to the target SNMP device:

  • SNMP v1: Use SNMP v1 for the connection. SNMP v1 only offers clear-text data transmission.
    i_round_redSNMP v1 does not support 64-bit counters. This might result in invalid data when you monitor traffic via SNMP.
  • SNMP v2c (recommended): Use SNMP v2c for the connection. SNMP v2c also only offers clear-text data transmission but it supports 64-bit counters.
  • SNMP v3: Use SNMP v3 for the connection. SNMP v3 provides secure authentication and data encryption.
    i_round_redSNMP v3 has performance limitations because of the use of encryption. The main limiting factor is CPU power. Also keep in mind that SNMP v3, unlike SNMP v1 and v2c, does not scale with more CPU power. Because of this limitation, PRTG can only handle a limited number of requests per second so that you can use only a limited number of sensors using SNMP v3. If you see an increase in Interval Delay or Open Requests with the Probe Health sensor, distribute the load over multiple probes. SNMP v1 and SNMP v2c do not have this limitation.

Community String

This setting is only visible if you select SNMP v1 or SNMP v2c (recommended) above. Enter the community string of your device. This is like a clear-text password for simple authentication.

i_round_blueWe recommend that you use the default value.

Authentication Method

This setting is only visible if you select SNMP v3 above. Select the authentication method:

  • MD5: Use message-digest algorithm 5 (MD5) for authentication.
  • SHA: Use Secure Hash Algorithm (SHA) for authentication.

i_round_blueIf you do not want to use authentication but you need SNMP v3, for example, because your device requires context, you can leave the Password field empty. In this case, PRTG uses SNMP_SEC_LEVEL_NOAUTH and it entirely deactivates authentication.

i_round_redThe authentication method you select must match the authentication method of your device.

User Name

This setting is only visible if you select SNMP v3 above. Enter the user name for access to the target SNMP device.

i_round_redThe user name that you enter must match the user name of your device.

Password

This setting is only visible if you select SNMP v3 above. Enter the password for access to the target SNMP device.

i_round_redThe password that you enter must match the password of your device.

Encryption Type

This setting is only visible if you select SNMP v3 above. Select an encryption type:

  • DES: Use Data Encryption Standard (DES) as the encryption algorithm.
  • AES: Use Advanced Encryption Standard (AES) as the encryption algorithm.

i_round_blueNet-SNMP does not support AES-192 and AES-256. They do not have RFC specifications.

i_round_redThe encryption type that you select must match the encryption type of your device.

Encryption Key

This setting is only visible if you select SNMP v3 above. Enter an encryption key. If you provide a key, PRTG encrypts SNMP data packets with the encryption algorithm that you selected above. Enter a string or leave the field empty.

i_round_redThe encryption key that you enter must match the encryption key of your device. If the encryption keys do not match, you do not get an error message.

Context Name

This setting is only visible if you select SNMP v3 above. Enter a context name only if the configuration of the device requires it. Context is a collection of management information that is accessible by an SNMP device. Enter a string.

Windows Compatibility Options

Click b_inherited_enabled to interrupt the inheritance.

If you experience problems when you monitor via Windows sensors, use the following compatibility options for troubleshooting.

Windows Compatibility Options

Windows Compatibility Options

Setting

Description

Preferred Data Source

i_round_blueThis setting only applies to hybrid sensors that use both performance counters and Windows Management Instrumentation (WMI). The setting does not apply to other sensors.

Define the method that Windows sensors use to query data:

  • Performance counters and WMI as fallback: Try to query data via performance counters. If this is not possible, establish a connection via WMI.
  • Performance counters only: Query data via performance counters only. If this is not possible, the sensor returns no data.
  • WMI only (recommended): Query data via WMI only. If this is not possible, the sensor returns no data. We recommend that you use this option.

Timeout Method

Select the time that the sensor waits for the return of the WMI query before the sensor cancels the query and shows an error message:

  • Use 1.5× scanning interval (recommended): Multiply the scanning interval of the sensor by 1.5 and use the resulting value.
  • Set manually: Manually enter a timeout value.

i_round_blueWe recommend that you use the default value.

i_round_blueIf you experience ongoing timeout errors, try increasing the timeout value.

Timeout (Sec.)

This setting is only visible if you select Set manually above. Enter the time the sensor waits for the return of its WMI query before it cancels it and shows an error message. Enter an integer. The maximum timeout value is 900 seconds (15 minutes).

SNMP Compatibility Options

Click b_inherited_enabled to interrupt the inheritance.

If you experience problems when you monitor via Simple Network Management Protocol (SNMP) sensors, use the following compatibility options for troubleshooting.

SNMP Compatibility Options

SNMP Compatibility Options

Setting

Description

SNMP Delay (ms)

Enter the time in milliseconds (ms) that PRTG waits between two SNMP requests. This can increase device compatibility. Enter an integer. You can define a delay between 0 and 100. PRTG does not support higher delays.

i_round_blueWe recommend that you use the default value.

i_round_blueIf you experience SNMP connection failures, try increasing the delay.

Failed Requests

Select if an SNMP sensor tries again after a request fails:

  • Retry (recommended): Try again if an SNMP request fails. This can prevent false error messages because of temporary timeout failures.
  • Do not retry: Do not retry if an SNMP request fails. If you select this option, an SNMP sensor shows a Down status earlier.

Overflow Values

Select how PRTG handles overflow values. Some devices do not correctly handle internal buffer overflows. This can cause false peaks.

  • Ignore (default): Ignore overflow values and do not include them in the monitoring data. We recommend that you use this option.
  • Handle overflow values as valid results: Regard all overflow values as regular data and include them in the monitoring data.

i_round_blueIf you experience problems because of strange peaks in your data graphs, change this option. Peaks might indicate that the target device resets counters without an overflow. PRTG interprets such behavior as overflow that results in data peaks. Select the option Ignore (default) in this case. For more details, see the Knowledge Base: What is the Overflow Values setting in the SNMP Compatibility Options?

Zero Values

Select how PRTG handles zero values. Some devices send incorrect zero values. This can cause false peaks.

  • Ignore (recommended): Ignore zero values and do not include them in the monitoring data. We recommend that you use this option.
    i_round_blueIf you experience problems, try changing this option.
  • Handle zero values as valid results for delta sensors: Regard all zero values as regular data and include them in the monitoring data.

32-bit/64-bit Counters

Select the type of traffic counters that PRTG searches for on a device:

  • Use 64-bit counters if available (recommended): The interface scan uses 64-bit traffic counters, if available. This can avoid buffer overflows in the devices

i_round_blueWe recommend that you use the default value.
i_round_blueIf you experience problems, try changing this option.

  • Use 32-bit counters only: The interface scan always uses 32-bit traffic counters, even if 64-bit counters are available. This can make monitoring more reliable for some devices.

Request Mode

Select the request method that PRTG uses for SNMP sensors:

  • Use multi get (recommended): Bundle multiple SNMP requests into one request. We recommend that you use this option.
    i_round_blueIf you experience problems, try changing this option.
  • Use single get: Use one request for each SNMP value. This can increase compatibility with older devices.

i_round_bluePRTG uses paging for SNMP requests. This means that if a sensor has to query more than 20 object identifiers (OID), it automatically polls the OIDs in packages of 20 OIDs each.

Walk Mode

Select the kind of SNMP walk that PRTG uses for SNMP sensors:

  • Use GETBULK requests (recommended): Request the next x OIDs in one SNMP request. The default value is 10. It is dynamic based on the response size.
    i_round_redThis option only works with devices that support SNMP as of version v2c. Make sure that you set the correct SNMP Version in the Credentials for SNMP Devices settings of the parent device or inherit it from objects that are higher in the object hierarchy.
  • Use GETNEXT requests: Request one OID at a time. This can increase compatibility with older devices or with devices that have insufficient SNMP BULKWALK support.

Port Name Template

Select how PRTG displays the name of SNMP sensors. Enter a template that uses several variables. When you add new sensors, PRTG scans the interface for available counters at certain OIDs. At each OID, several fields with interface descriptions are usually available. They are different for every device and OID. PRTG uses the information in these fields to name the sensors. If a field is empty or if it is not available, PRTG adds an empty string to the name. By default, the port name template is ([port]) [ifalias] [ifsensor], which creates a name like (001) Ethernet1 Traffic. You can use and combine any field names that are available at an OID of your device, for example:

  • [port]: The port number of the monitored interface.
  • [ifalias]: The 'alias' name for the monitored interface as specified by a network manager, providing a non-volatile handling.
  • [ifname]: The textual name of the monitored interface as assigned by the local device.
  • [ifdescr]: A textual string containing information about the target device or interface, for example, manufacturer, product name, or version.
  • [ifspeed]: An estimate of the monitored interface's current bandwidth (Kbit/s).
  • [ifsensor]: The type of the sensor, this is Traffic or RMON. This helps to differentiate between SNMP Traffic and SNMP RMON sensors.

i_square_cyanFor more information about SNMP sensor names, see the Knowledge Base: How can I change the defaults for names automatically generated for new SNMP sensors?

Port Name Update

Select how PRTG reacts if you change the names of ports in your physical device (for example, a switch or router):

  • Keep port names (use this if you edit the names in PRTG): Do not automatically adjust sensor names. This is the best option if you want to manually change names in PRTG.
  • Automatically update sensor names if port names change in the device: If PRTG detects port name changes in your physical device, it tries to automatically adjust the sensor names accordingly.

i_square_cyanFor more information about automatic name updates, see the Knowledge Base: Automatically update port name and number for SNMP Traffic sensors when the device changes them.

Port Identification

Select the field that PRTG uses for SNMP interface identification:

  • Automatic identification (recommended): Try the ifAlias field first to identify an SNMP interface and then try ifDescr.
    i_round_bluePRTG does not automatically try ifName.
  • Use ifAlias: For most devices, ifAlias is the best field to use for unique interface names.
  • Use ifDescr: Use this option if the port order of your device changes after a restart, and if no ifAlias field is available. For example, this is the best option for Cisco ASA devices.
    i_round_blueIf you use this option, it is important that your device returns unique interface names in the ifDescr field.
  • Use ifName: You can also use this option if no unique ifAlias is available.
    i_round_blueIf you use this option, it is important that your device returns unique interface names in the ifName field.
  • Do not update ports: Use this option to disable the automatic port identification.

Start Interface Index

i_round_blueThis setting only applies to SNMP Traffic sensors and to Cisco IP SLA sensors.

Enter the index at which PRTG starts to query the interface range during sensor creation. Enter 0 for the automatic mode.

i_round_blueWe recommend that you use the default value.

End Interface Index

i_round_blueThis setting only applies to SNMP Traffic sensors and to Cisco IP SLA sensors.

Enter the index at which PRTG stops querying the interface range during sensor creation. Enter 0 for the automatic mode.

  • 12 hours
  • 24 hours

i_round_blueYou can change the available intervals in the system administration of PRTG Network Monitor.

If a Sensor Query Fails

Select the number of scanning intervals that the sensor has time to reach and to check a device again if a sensor query fails. Depending on the option that you select, the sensor can try to reach and to check a device again several times before the sensor shows the Down status. This can avoid false alarms if the target device only has temporary issues. For previous scanning intervals with failed requests, the sensor shows the Warning status. Choose from:

  • Set sensor to down status immediately: Set the sensor to the Down status immediately after the first request fails.
  • Set sensor to warning status for 1 interval, then set to down status (recommended): Set the sensor to the Warning status after the first request fails. If the second request also fails, the sensor shows the Down status.
  • Set sensor to warning status for 2 intervals, then set to down status: Set the sensor to the Down status only after the third request fails.
  • Set sensor to warning status for 3 intervals, then set to down status: Set the sensor to the Down status only after the fourth request fails.
  • Set sensor to warning status for 4 intervals, then set to down status: Set the sensor to the Down status only after the fifth request fails.
  • Set sensor to warning status for 5 intervals, then set to down status: Set the sensor to the Down status only after the sixth request fails.

i_round_blueSensors that monitor via Windows Management Instrumentation (WMI) always wait at least one scanning interval before they show the Down status. It is not possible to immediately set a WMI sensor to the Down status, so the first option does not apply to these sensors. All other options can apply.

i_round_blueIf you define error limits for a sensor's channels, the sensor immediately shows the Down status. None of the interval options apply.

i_round_blueIf a channel uses lookup values, the sensor immediately shows the Down status. None of the interval options apply.
