Gnocchi Archive policies | |
========================= | |
1. Capture data every 1 minute for 1 day | |
[heat-admin@overcloud-controller-2 ~]$ gnocchi archive-policy create 1min1day -d granularity:1m,timespan:1d | |
+---------------------+----------------------------------------------------------------+ | |
| Field | Value | | |
+---------------------+----------------------------------------------------------------+ | |
| aggregation_methods | std, count, 95pct, min, max, sum, median, mean | | |
| back_window | 0 | | |
| definition | - points: 1440, granularity: 0:01:00, timespan: 1 day, 0:00:00 | | |
| name | 1min1day | | |
+---------------------+----------------------------------------------------------------+ | |
2. Capture data for every 1 minute for 30 days | |
[heat-admin@overcloud-controller-2 ~]$ gnocchi archive-policy create 1min30day -d granularity:1m,timespan:30d | |
+---------------------+-------------------------------------------------------------------+ | |
| Field | Value | | |
+---------------------+-------------------------------------------------------------------+ | |
| aggregation_methods | std, count, 95pct, min, max, sum, median, mean | | |
| back_window | 0 | | |
| definition | - points: 43200, granularity: 0:01:00, timespan: 30 days, 0:00:00 | | |
| name | 1min30day | | |
+---------------------+-------------------------------------------------------------------+ | |
3. Same are above but using 'points'. 30 days is (30d x 24hrs. x 60min. = ) 43200 mins | |
[heat-admin@overcloud-controller-2 ~]$ gnocchi archive-policy create 1min43200points -d granularity:1m,points:43200 | |
+---------------------+-------------------------------------------------------------------+ | |
| Field | Value | | |
+---------------------+-------------------------------------------------------------------+ | |
| aggregation_methods | std, count, 95pct, min, max, sum, median, mean | | |
| back_window | 0 | | |
| definition | - points: 43200, granularity: 0:01:00, timespan: 30 days, 0:00:00 | | |
| name | 1min43200points | | |
+---------------------+-------------------------------------------------------------------+ | |
4. Every 30 days for 2 years. Note that 24 points = 2yrs x 12 mnths | |
[heat-admin@overcloud-controller-2 ~]$ gnocchi archive-policy create 1mnth2yrs -d granularity:30d,points:24 | |
+---------------------+--------------------------------------------------------------------------+ | |
| Field | Value | | |
+---------------------+--------------------------------------------------------------------------+ | |
| aggregation_methods | std, count, 95pct, min, max, sum, median, mean | | |
| back_window | 0 | | |
| definition | - points: 24, granularity: 30 days, 0:00:00, timespan: 720 days, 0:00:00 | | |
| name | 1mnth2yrs | | |
+---------------------+--------------------------------------------------------------------------+ | |
OR | |
(overcloud) [root@overcloud-controller-0 ~]# gnocchi archive-policy create verylow -d granularity:30d,timespan:720d | |
+---------------------+--------------------------------------------------------------------------+ | |
| Field | Value | | |
+---------------------+--------------------------------------------------------------------------+ | |
| aggregation_methods | std, count, min, max, sum, mean | | |

| name | verylow | | |
+---------------------+--------------------------------------------------------------------------+ | |
5. Include multiple granularity | |
[heat-admin@overcloud-controller-2 ~]$ gnocchi archive-policy create verylow -d granularity:30d,points:24 -d granularity:1d,timespan:30d | |
+---------------------+--------------------------------------------------------------------------+ | |

+---------------------+--------------------------------------------------------------------------+ | |
| aggregation_methods | std, count, 95pct, min, max, sum, median, mean | | |
| back_window | 0 | | |
| definition | - points: 24, granularity: 30 days, 0:00:00, timespan: 720 days, 0:00:00 | | |
| | - points: 30, granularity: 1 day, 0:00:00, timespan: 30 days, 0:00:00 | | |
| name | verylow | | |
+---------------------+--------------------------------------------------------------------------+ | |
6. Create archive-policy rule | |
$ gnocchi archive-policy create 1min1day -d granularity:1m,timespan:1d | |
+---------------------+----------------------------------------------------------------+ | |
| Field | Value | | |
+---------------------+----------------------------------------------------------------+ | |
| aggregation_methods | std, count, min, max, sum, mean | | |
| back_window | 0 | | |
| definition | - points: 1440, granularity: 0:01:00, timespan: 1 day, 0:00:00 | | |
| name | 1min1day | | |
+---------------------+----------------------------------------------------------------+ | |
$ (overcloud) [root@overcloud-controller-0 heat-admin]# gnocchi archive-policy-rule create cpu -a 1min1day -m "cpu*" | |
+---------------------+----------+ | |
| Field | Value | | |
+---------------------+----------+ | |
| archive_policy_name | 1min1day | | |
| metric_pattern | cpu* | | |
| name | cpu | | |
+---------------------+----------+ | |
$ (overcloud) [root@overcloud-controller-0 heat-admin]# gnocchi archive-policy-rule list | |
+---------+---------------------+----------------+ | |
| name | archive_policy_name | metric_pattern | | |
+---------+---------------------+----------------+ | |
| cpu | 1min1day | cpu* | | |
| default | low | * | | |
+---------+---------------------+----------------+ | |
(Note for archive-pilicy-rule): Please also make changes in /etc/gnocchi/gnocchi.conf and /etc/ceilometer/ceilomter.conf if you want to apply archive policy rule. | |
~~~/etc/gnocchi/gnocchi.conf | |
[statsd] | |

Note: | |
1. `bb912729-fa51-443b-bac6-bf4c795f081d` is instance/resource-id | |
2. Event type is actually nova compute events. Full list here: https://wiki.openstack.org/wiki/SystemUsageData | |
3. When event is triggered..in this case instance is powered on/off, relevant event is seen in /var/log/aodh/listener.log | |
