Overview
The IBH Link UA can be integrated into a Nagios-compatible monitoring system through NRPE (Nagios Remote Plugin Executor). This allows device status and approved check values to be queried centrally.
Configuration
The Nagios page of the web interface provides the following functions:
- display the current NRPE service status
- start the NRPE service automatically with the device
- configure the TCP port; the default is
5666 - configure the permitted queries or checks
- apply the settings
- start or stop the service
- refresh the status display
Applying changed settings restarts the NRPE service with the new configuration.
Setup
- Configure the required port and permitted queries.
- Enable automatic startup if monitoring is to be used permanently.
- Apply the settings and refresh the service status.
- Create a host for the IBH Link UA in the Nagios system.
- Query the approved checks using
check_nrpe. - Test the return value and status text manually before adding the check to regular monitoring.
Network and security
- Make the NRPE port reachable only from the intended monitoring network.
- Restrict access through the firewall to the required Nagios systems.
- Permit only the queries that are actually required.
- Do not use passwords or other secrets as query parameters.
Troubleshooting
- Check network access to the IBH Link UA and the configured TCP port.
- Verify that the NRPE service is running and enabled for device startup.
- Check firewall rules on the IBH Link UA and in the network.
- Make sure that the query name used by Nagios exactly matches an approved query.
- After configuration changes, apply the settings again and refresh the status.
