Hi Greg,
Sorry for not responding earlier about your Nagios problem, most of the Vitrage
team is busy preparing to Boston.
We have already heard about the Ubuntu 16.04 issue but didn’t investigate it
yet, so unfortunately I don’t have a solution for you at the moment. If you are
only interested in having alarms in Vitrage, there are several options to
achieve this.
1. Use Yujun’s suggestion
2. Raise a “compute down” alarm and let the Doctor datasource handle it.
You need to:
· Make sure ‘doctor’ is defined in the list of ‘types’ in
/etc/vitrage/vitrage.conf (if not, add it and restart vitrage-graph)
· Send an event to Vitrage using the CLI:
vitrage event post --type="compute.host.down"
--details='{"hostname":"<your_hostname>","source":"sample_monitor","cause":"link-down","severity":"critical","status":"down","monitor_id":"monitor-1","monitor_event_id":"123"}'
3. Raise an Aodh alarm with constant state ‘alarm’
· Make sure ‘aodh’ is defined in the list of ‘types’ in
/etc/vitrage/vitrage.conf (if not, add it and restart vitrage-graph)
· Call aodh CLI:
aodh alarm create --type threshold --name 'cpu_alarm' --state alarm
--description 'CPU utilization is above 1%' -m 'cpu_util' --period 60
--threshold 0.01 --comparison-operator gt --query 'resource_id=< instance
uuid>' --enabled False
Hope this helps.
Best Regards,
Ifat.

One easy way could be writing a scenario to raise deduced alarm based on a
simple rule, e.g. when a host is discovered, raise an alarm saying host is up.

I don’t think I saw any responses to this.
Alternative question ... so I’ve got vitrage up and running fine ...
What’s the easiest way to generate an alarm against a host ? ( OTHER than
NAGIOS, due to problem in original email ) ???
let me know any ideas,
Greg.

Subject: [openstack-dev] [vitrage] trouble installing Nagios on devstack on
ubuntu 16.04 ...
Hey ... I’m working thru the ‘Vitrage - Getting Started Guide’
https://docs.openstack.org/developer/vitrage/vitrage-first_steps.html
Was able to get vitrage up and running and enabled in horizon ... on ubuntu
16.04 .
( I tried on ubuntu 14.04 and ‘./stack.sh’ warned that it had not been
tested on trusty (14.04), I FORCE=yes it ... but it failed. )
Now trying to install Nagios in devstack
https://docs.openstack.org/developer/vitrage/nagios-devstack-installation.html
BUT it doesn’t seem like there is an OMD package available for ubuntu 16.04 ...
and the trusty (14.04) package won’t install due to dependency issues.
Any suggestions ?
Greg.
