Hi Nicolas,

These are DWH error. I see in engine.log that around the time you are
referring to there are many connectipn errors to the postgresql database.
When DWH is unable to connect to the engine database and error is sent to
the ovirt-engine-history.log.
I don't see the error you are referring to in the engine.log.

The DWH samples every 20 second for statistics that are used to create the
ovirt dashboards.

If there is a problem with the postgres connection then the hourly
aggregation of the samples failed too.

I see that first postgres connection error started at 2017-04-20
11:06:04,162+01 ERROR .
I see the problem with the database is still not fixed.
Please check for the reason your database connection keeps closing.

Best regards,

Hi,

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:


ETL service sampling has encountered an error. Please consult the 
service log for more details.


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.


Also, at 11:07:58 this event showed up:

Engine server is not responding.

And at 11:12:58 it seems to recover:

Engine server is up and running.

At 12:00:00 this message showed up:

ETL service aggregation to hourly tables has encountered an error. 
Please consult the service log for more details.


But relative to this one I see nothing in logs.

Could someone clarify what these error messages mean?

Thanks.

Hi,

This in a known issue.
We have a bug targeted to 4.2 for this.
https://bugzilla.redhat.com/show_bug.cgi?id=137
This error means that the dwh tried to reach the engine database and for
some reason the heartbeat of the engine did not update since the last dwh
sync.

Thank you Fernando and shirly  for the explanation

The ETL sampling process collects the configurations and statistics

The engine has a heartbeat that should update every 15 seconds. 
Sampling runs every 20 seconds.
If the engine is busy and the heartbeat does not update for some 
reason , the dwh will send an error. It compares the last sync with 
the heartbeat.

Heartbeat should be newer than the last sync...

Kasturi,

 I had the same issue and here is what Yaniv said:

 

This can happen when the engine is down or very busy. This error seems
to happen only sometimes, which indicates this is the case.

 In my case my engine was very busy.
 Good luck!
