NRPE check timeout

[majduk]

Due to a fact that contrail-status runs for over 10s, contrail nagios check times out:

root@UPSR-BRBFD-01-0008:~# time /usr/local/lib/nagios/plugins/check_contrail_status_controller.py 5.1
Contrail status OK

real    0m11.399s
user    0m0.132s
sys     0m0.057s

This leads to a false positive alarm in nagios.

looks like it's not positive... why contrail-status works more than 10seconds? i saw when DNS doesn't work correctly - it can take 10 seconds.

All units report status OK. Also in Contrail WebUI there are no alarms. Nothing that could indicate an issue whatsoever.:

ok, got it. but honestly I don't why zookeeper is so slow in your env. and I can't say how to increase nrpe check timeout right now (and i don't think that it's a good way)

[majduk]

I've already increaset the timeout.

contrail-status takes pretty much the same amount of time in all envs where we have 19.XX release.

deleted my old comments, because those were pointing to some other problem which is not related to this issue. thanks
