[apps::varnish::local::plugin] - mode(stats): No graphs will created - Buffer creation

[joschi99]

Latest plugin version

No graphs will created when using this command:
--plugin=apps::varnish::local::plugin --hostname=x.x.x.x --ssh-username=user --filter-perfdata='^(client_req|cache_hit|cache_hitpass|cache_miss|backend_conn|backend_busy|backend_unhealthy|backend_fail|sess_drop|sess_fail|sess_queued|threads_failed)$' --mode=stats

On GUI you can see the following:

We can exclude that the problem is not depending on perl connector.

When you force a check through the GUI then the perf datas will be returned correctly but only for this forced check for 1 time:

Next scheduled check by the engine will reproduce newly the problem

Also deleting the cache file will not solve the problem.

Hello :)

So if I understand correctly, only the force check (once) will allow the plugin to work correctly?

[joschi99]

Yes

[lucie-dubrunfaut]

All right, I'll check with the dev team to look at the subject at our next session, and I'll keep you informed.

If you need we can show this behaviour durang a remote session.

Hello :)

Could you test on command line the same action as centreon-engine user to check if the issue is occuring also this way.
We should also schedule a remote session (we'll see this by mail).

I can confirm that the problem was related that both services was using the same stats file.
