SolarWinds CBQoS collection suddenly stopped working

NetDev_sol

Why is the CBQoS has stopped on few nodes suddenly, when on the same polling Engine other nodes are working fine, there were no logs showing any abnormality.

points to consider:
Effected Nodes are from same Polling Engine
All stopped around same timestamp
SNMP is working fine

@NetDev_sol Believe I found your case, and we have already reviewed the data provided. We will reach out with more specific information, but there appears to be an interesting scenario in which the job engine and collector stopped working (or at least stopped recording data in the logs). There was an attempt to stop/start services, which fixed some problems. This would have caused loss of historical data between this time, but we should generally expect these jobs to resume and try again. Several of these CBQoS sources appear to be stuck and would need to be manually enabled/disabled to get them kicked off again.

The next step is for us to discuss whether there is a better way to ensure these scenarios are automatically recovered and retried without manual steps. Additionally, clear and visible information about the sources is no longer working.
