I am using ceilometer version 2.4.0 and openstack version 2.2.0

root@node-1:~# ceilometer --version
2.4.0
root@node-1:~# openstack --version
openstack 2.2.0

I am trying to do an alarm which has to be triggered when cpu utilization is greater then 50% for more than 60 seconds. Below is the command that I have used:

 ceilometer alarm-threshold-create --name enea_cpu_anva --description "Anva instance running hot" --meter-name cpu_util --threshold 50 --comparison-operator gt --statistic avg --period 60 --evaluation-periods 1 --repeat-actions True --enabled True --alarm-action 'log://' --query resource_id=34ef4464-1c18-4b84-97cd-ed57e2ac6b91

I have logged on the VM instance and made CPU to have constant 90% utilization.

Please let me know where should I look for the allarm log since I can't find any notifications. The alarm was created with --alarm-action 'log://" but I don't know where it logs and from documentation I can't find it.

This is copy paste from documentation:

"
Log actions

These are a lightweight alternative to webhooks, whereby the state transition is simply logged by the alarm-notifier, and are intended primarily for testing purposes.

Many thanks, Andrei Varvara
