Dependencies

The Results-Forwarder requires access to the MessageQueue and Registry. Please make sure these packages are installed, configured and running before attempting to start the results forwarder process.

Installation

Refer to Advanced Automated Installation.

Configuration

The user configuration options should be set in /opt/opsview/resultsforwarder/etc/resultsforwarder.yaml. Default values are shown in /opt/opsview/resultsforwarder/etc/resultsforwarder.defaults.yaml, but changes should not be made here since the file will get overwritten on package update.

The following options can be set:

• results_fifo: Location of the results FIFO. Default is /opt/opsview/var/results.sock.
• resultssender_queue: The message-queue configuration to send results.
• registry: Connection configuration for the Registry.
• logging: Component logging configuration.

Submitting results

Results and acknowledgements can be submitted into Opsview Monitor by writing into the /opt/opsview/var/results.sock pipe file. This can be used for submitting passive checks.

Entries should be written in the following format:

[<timestamp>] PROCESS_SERVICE_CHECK_RESULT;<host_name>;<service_name>;<return_code>;<plugin_output>
[<timestamp>] PROCESS_HOST_CHECK_RESULT;<host_name>;<return_code>;<plugin_output>
[<timestamp>] ACKNOWLEDGE_HOST_PROBLEM;<host_name>;<sticky>;<notify>;<persistent>;<author>;<comment>
[<timestamp>] ACKNOWLEDGE_SVC_PROBLEM;<host_name>;<service_name>;<sticky>;<notify>;<persistent>;<author>;<comment>

Note

The timestamp should be in epoch format.

For example, to submit a passive result that has just occurred, with a WARNING state (1) and the output text “example text” to a Service “serviceA” on Host “host1”:

echo "[$(date +'%s')] PROCESS_SERVICE_CHECK_RESULT;host1;serviceA;1;example text" >> /opt/opsview/var/results.sock

Unknown hosts or services will be logged into syslog.

Management

Configuration

DPKGs

Watchdog service files are now managed by the package, doing a remove would leave the watchdog service file behind with a .save extension. Purging the package will remove it. The package managed config files are as follows

/opt/opsview/watchdog/etc/services/opsview-resultsforwarder.conf

RPMs

Watchdog service files are now managed by the package. Any modifications will be saved at upgrade and remove processes with the .rpmnew and .rpmsave extensions correspondingly.

opt/opsview/watchdog/etc/services/opsview-resultsforwarder.conf

Service administration

As root, start, stop and restart the service using:

/opt/opsview/watchdog/bin/opsview-monit <start|stop|restart> opsview-resultsforwarder
