That worked :)
Thanks a lot Ifat.
I see the cpu alarm reported in vitrage now :).
( and in the /tmp/python-notifications.dump file that volodomyr helped me with )
Only final issue is that the vitrage alarm does not clear when I see the clear
notification ( ? severity 4 ? )in /tmp/python-notifications.dump.
I waited about 10 mins ... in case there was some hysteresis or something.
I am using a late version of ocata.
in /tmp/python-notifications.dump:

Hi Greg,
There is an exception in vitrage-graph, since the configuration for
devstack-vitrage/cpu/0 was not found.
Please verify that your collectd_conf.yaml looks like that:
collectd:
- collectd_host: devstack-vitrage/cpu/0
type: <openstack resource type, e.g. nova.host>
name: <openstack resource name, e.g. host1>
- collectd_host: …
If this doesn’t help, please send me the file and I’ll have a look.
Best Regards,
Ifat.

Subject: Re: [openstack-dev] [vitrage] Collectd - to - Vitrage setup issues
Hi Ifat,
I was able to fix and verify that my collectd configuration is correct and
working with the help of volodomyr ... i.e. I have a much simpler collectd.conf
with a threshold set on cpu-0 idle percentage and a simple python plugin to
dump notifications to a file.
I added in the vitrage collectd plugin to this simple setup ... but still don’t
see vitrage alarms displayed on the vitrage dashboard ☹ .
I have attached the vitrage-graph.log
I have attached my now much simpler collectd.conf file
I have also attached the only templates I have defined under
/etc/vitrage/templates ... wondering if I need updated templates for working
with collectd notifications ?
let me know if you have any ideas,
Greg.

Hi Greg,
You should access the vitrage-graph.log using journalctl:
sudo journalctl --no-pager --unit

Hi Greg,
Vitrage listens to Collectd notifications, not statistics.
Can you please turn on the debug option in /etc/vitrage/vitrage.conf (set
“debug = true”), and send me the vitrage-graph.log?
Thanks,
Ifat.

Subject: Re: [openstack-dev] [vitrage] Collectd - to - Vitrage setup issues
Hi Ifat,
thanks for the reply ... just got around to trying your suggestions.
This definitely helps ... I no longer get any errors on re-starting collectd or
vitrage-graph.
i.e. it appears to load the collectd and updated vitrage conf files correctly
now.
Now still don’t get any alarms in vitrage.
HOWEVER I suspect it may be my collectd setup now.
( WARNING I am NOT a collectd expert. ;) )
I suspect that the vitrage-collectd plugin only sends collectd NOTIFICATIONS or
THRESHOLD Events to vitrage.
i.e. it likely does NOT send just statistic/status samples to vitrage.
I can see that collectd sampling is happening ... I have logfile and csv and
rrd plugins running and samples are being captured in the specified directories
/ files.
I tried to set threshold for CPU based on an example I had found on web.
See attached collectd.conf file .
BUT really not sure if the threshold configuration in my collectd.conf is
correct or working ... is there a way to confirm this ? ( any collectd
experts out there ? )
OR
Is there an example collectd.conf that has notifications or thresholds
(whatever vitrage needs) setup for something basic like CPU ?
Greg.

Hi Greg,
I’m less familiar with the collectd configuration and the events that it sends.
Regarding the collectd_conf.yaml, it is definitely missing. You should add a
/etc/vitrage/collectd_conf.yaml file that looks like that:
collectd:
- collectd_host: <collectd resource name>
type: <openstack resource type, e.g. nova.host>
name: <openstack resource name, e.g. host1>
- collectd_host: …
This file maps a Collectd resource to the corresponding resource in OpenStack.
Only resources that are listed in this file will have their alarms imported to
Vitrage.
Next, you should add a reference to this file in /etc/vitrage/vitrage.conf:
[collectd]
config_file = /etc/vitrage/collectd_conf.yaml
Then you should restart vitrage-graph.
Let me know if it helped,
Ifat.

I am trying to get collectd to report some alarms to vitrage in a devstack
setup,
I am using a devstack created on a late version of ocata.
And my devstack with vitrage appears to be working ok otherwise;
e.g. I can create VMs, and raise fake alarms using “vitrage event post
-type=compute.host.down ...” or with “aodh alarm create ...
resource_id=instance-uuid” ... and they get reported fine in vitrage.
UNFORTUNATELY not seeing anything in vitrage from collectd, and
don’t believe I’m seeing anything even from collectd,
for example from the syslog output plugin.
I’ve attached the following files: ( not sure if these get distributed on
mailing list )
· /etc/collectd/collectd.conf <-- do these look ok ?
· /etc/vitrage/vitrage.conf <-- do these look ok ?
· /var/log/syslog ... around the time when I updated
collectd.conf and vitrage.conf and restarted collectd and vitrage-graph
o QUESTIONS
• NOTE THE FOLLOWING ERRORS IN THE SYSLOG FILE ... where do I get the
collectd_conf.yaml file from ? Can’t see it in the devstack files for vitrage.

Any other suggestions on things to look at in order to understand what’s wrong ?
