<br>
We're using oVirt 4.1.1.8 (upgraded yesterday) and since it has been showing some strange errors I'd like to know about:<br>
<br>
ETL service sampling has encountered an error. Please consult the service log for more details.<br>
<br>
I'm attaching the engine log FWIW. This message showed up at 11:07:04 but in the log I see the exceptions started 1 minute ago.<br>
<br>
Also, at 11:07:58 this event showed up:<br>
<br>
Engine server is not responding.<br>
<br>
And at 11:12:58 it seems to recover:<br>
<br>
Engine server is up and running.<br>
<br>
At 12:00:00 this message showed up:<br>
<br>
ETL service aggregation to hourly tables has encountered an error. Please consult the service log for more details.<br>
<br>
But relative to this one I see nothing in logs.<br>
<br>
Could someone clarify what these error messages mean?<br>
<br>
Thanks.<br>______________________________<wbr>_________________<br>
