Description Andreas Karis 2017-01-18 20:10:09 UTC 
Description of problem:
https://access.redhat.com/solutions/2215701

The current default value in Director based deployments for these values:
~~~
[database]
#(IntOpt) Number of seconds that alarm histories are kept in the database for (<= 0 means forever).
#alarm_history_time_to_live = -1
# (IntOpt) Number of seconds that events are kept in the database for (<= 0 means forever).
event_time_to_live = -1
# (IntOpt) Number of seconds that samples are kept in the database for (<= 0 means forever).
metering_time_to_live = -1
~~~

Databases regularly fill up root disks with these settings. We should set these to a reasonable value. Definitely not infinite retention.
Comment 3 David Juran 2017-10-02 16:43:28 UTC 
In OSP10, with Aodh deployed by default, shouldn't the alarm_history_time_to_live parameter also be set in aodh.conf?
Comment 4 Sasha Smolyak 2017-11-13 14:36:46 UTC 
1. 
[heat-admin@controller-0 ~]$ sudo docker exec -ti ceilometer_agent_central cat /etc/ceilometer/ceilometer.conf | grep time_to_live
# Deprecated group/name - [database]/time_to_live
#metering_time_to_live = -1
metering_time_to_live=-1
event_time_to_live=-1

Although in /usr/share/openstack-tripleo-heat-templates/puppet/services/ceilometer-collector.yaml all the changes are according to gerrit:

  CeilometerEventTTL:
    default: '86400'
    description: Number of seconds that events are kept in the database for
                 (<= 0 means forever)
    type: string
  CeilometerMeteringTTL:
    default: '86400'
    description: Number of seconds that samples are kept in the database for
                 (<= 0 means forever)
    type: string

2. 
[heat-admin@controller-0 ~]$ sudo docker exec -ti aodh_api cat /etc/aodh/aodh.conf | grep alarm_history_time_to_live
#alarm_history_time_to_live = -1

This default was never fixed

The defaults aren't changed

Comment 5 Pradeep Kilambi 2017-11-13 15:10:02 UTC 
Your test is incorrect, you need collector deployed in order to set the ttl. As those are mongodb only settings really.
