See this little RDO getting-started guide I wrote a while back: http://openstack.redhat.com/CeilometerQuickStart there's an example therein of creating an alarm via the CLI: $ ceilometer alarm-threshold-create --name cpu_high --description 'instance running hot' \ --meter-name cpu_util --threshold 70.0 --comparison-operator gt --statistic avg \ --period 600 --evaluation-periods 3 \ --alarm-action 'log://' \ --query resource_id=INSTANCE_ID Just modify the period, evaluation-periods, threshold to suit your use-case. To see the actual JSON payload, simply use the --debug option: $ ceilometer --debug alarm-threshold-create ... ... curl -i -X POST -H 'X-Auth-Token: TOKEN' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'User-Agent: python-ceilometerclient' -d '{"alarm_actions": ["log://"], "description": "instance running hot", "threshold_rule": {"meter_name": "cpu_util", "evaluation_periods": 3, "period": 600, "statistic": "avg", "threshold": 70.0, "query": [{"field": "resource_id", "type": "", "value": "INSTANCE_ID", "op": "eq"}], "comparison_operator": "gt"}, "repeat_actions": false, "type": "threshold", "name": "cpu_high"}' http://IP_ADDR:8777/v2/alarms You could also look at the official project API docco here: http://docs.openstack.org/developer/ceilometer/webapi/v2.html Cheers, Eoghan > > I saw this example in a presentation somewhere, but it’s not exactly > self-explanatory. > > POST /v2/alarms > > { > "alarm_actions": [ > "http://site:8000/alarm"; > ], > "insufficient_data_actions": [ > "http://site:8000/nodata"; > ], > "ok_actions": [ > "http://site:8000/ok"; > ], > "comparison_operator": "gt", > "description": "An alarm", > "evaluation_periods": 2, > "matching_metadata": { > "key_name": "key_value" > }, > "meter_name": "storage.objects", > "name": "SwiftObjectAlarm", > "period": 240, > "statistic": "avg", > "threshold": 200 > } > > Thanks, > Mark > > _______________________________________________ > Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack > Post to : openstack@lists.openstack.org > Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack > _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
