PRTG Manual: Add a Group

Group Name

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

If 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?

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.

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

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

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 (default): 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.

Auto-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 (default): 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.
  Use 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.

For performance reasons, PRTG sets Schedule to Once (default) 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.

PRTG can only handle keys in the OpenSSH format that are not encrypted. You cannot use password-protected keys.

PRTG only supports RSA keys. It does not support DSA keys.

For more information, see section Monitoring via SSH.

If you want to enter a private key for the first time or change the private key, you need to restart the PRTG core server service for the private key change to take effect.

WBEM Protocol

Select the protocol that you want to use for the connection to the system via WBEM:

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

This setting is only relevant if you use WBEM sensors.

WBEM Port

Select if you want to use one of the default ports for the connection to the system via WBEM or if you want to set a custom port:

• Default: Use one of the default ports. The default port for unsecure connections is 5988 and the default port for secure connections is 5989.

By 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: 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.

We strongly recommend that you use the default connection mode.

• HTTPS (default): 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 (default): 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.

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.
  SNMP v1 does not support 64-bit counters. This might result in invalid data when you monitor traffic via SNMP.
• SNMP v2c (default): 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.
  SNMP 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 (default) above.

Enter the community string of your device. This is like a clear-text password for simple authentication.

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

• SHA-256: Use SHA-256 for authentication.
• SHA-384: Use SHA-384 for authentication.
• SHA-512: Use SHA-512 for authentication.

If 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.

The authentication method that you select must match the authentication method of your device.

User Name
