Opsview - Why does my collector show the wrong Opsview version in the UI?

In the Registered Collectors table on the Configuration > Monitoring Collectors > Collectors page, you can see the Opsview version running on each collector.

The version number shown in in the Registered Collectors table is taken from the package version of the opsview-scheduler package.

If the Registered Collectors table shows your collector is running an older Opsview version than you expect, you should check each of the below.

Is the collector actually running the expected version?

Are all the Opsview packages on the collector updated for the expected Opsview version?

# Ubuntu/Debian:
apt list --installed | grep opsview
# CentOS/RHEL:
yum list installed | grep opsview

Check the correct expected package versions for your Opsview release on this page.

If the packages do not match those of your expected Opsview release, install the correct packages on the collector using opsview-deploy.

Does the opsview-scheduler package version match the release version?

The version shown in the Registered Collectors table is taken from the version of the installed opsview-scheduler package. Some Opsview updates do not affect the opsview-scheduler package so it may look like your collector has an older version because the opsview-scheduler package version does not match the release version.

Check the correct expected opsview-scheduler package version for your Opsview release on this page.

Restart the opsview-scheduler component

If the correct packages are installed and the version shown in the the Registered Collectors table does not match the installed opsview-scheduler package, you should try restarting the opsview-scheduler component:

1. Log in to the affected collector as root.
2. Stop the opsview-scheduler component using opsview-monit:

/opt/opsview/watchdog/bin/opsview-monit stop opsview-scheduler

3. Wait for 60 seconds:

sleep 60

4. Start the opsview-scheduler component using opsview-monit:

/opt/opsview/watchdog/bin/opsview-monit start opsview-scheduler
