[Xymon] new apache performance graphs not working

[Dugan, Darin D [EIT]]

Hmm, well I remember having a similar problem a while back but in my case the cause was forgetting to set ExtendedStatus. I'm probably not much more help, but if you haven't already I'd check the apache logs to see that the request to server-status is coming in, returning a 200, etc, and then compare rrdtool dumps from the working and non-working servers. Good luck.

Darin,

Thanks for the reply, but I already checked. I can get the extended status with a browser running on the Xymon server, no problem.

Would attaching or pasting part of the rrdtool dump of the apache.rrd file to the list be of any help?

Thanks,
Steve

I would first double check that the apache admin set ExtendedStatus On, not just enabled server-status and allowed from Xymon server. (man 5 bb-hosts)

Cheers.

Xymon 4.2.3.
I'm really puzzled. I have been asked to add the apache performance graphs to a handfull of servers. I used the suggestion found on the 'tips' page under Help in the Xymon menu. Specifically:


1.2.3.4    my.server.com<http://my.server.com>  # conn ssh http://1.2.3.4 apache=http://1.2.3.4/server-status?auto TRENDS:*,apache:apache|apache1|apache2|apache3

The puzzle is it works for the first one we did as a test. Then I copied the relevant bb-hosts configuration tags (http, apache, TRENDS)  from that host to another two with changes to hostnames. The app admin made the necessary changes to the apache server. The server-status request works from a browser on both of the servers in question (running the browser on the Xymon server). There are apache.rrd files in the data/rrd directory, and the graphs appear on the trends page, but in there is no data being graphed. Nothing but NaN in the values at the bottom of the graph.

I stopped Xymon and removed one of the apache.rrd files and restarted Xymon and have now waited a sufficient amount of time and still nothing is showing up in the graphs.

What am I missing? I know I'm about 2 days behind on sleep, but this should just work, especially since it worked on the first one we did.

Thanks,
Steve
