Description Andrew Ludwar 2018-04-20 17:58:20 UTC

Description of problem:

Customer has a large panko database size and is affecting performance. The events don't seem to have a cleanup or expiry process.


Version-Release number of selected component (if applicable):

OSP12

How reproducible:

Every time.

Steps to Reproduce:
1. Deploy OSP12
2. Observe panko events count always increase:

MariaDB [panko]> use panko;
Database changed
MariaDB [panko]> select count(*) from event;
+----------+
| count(*) |
+----------+
|  1736043 |
+----------+
1 row in set (0.37 sec)

3. Observe MySQL database growing in size.


Actual results:

Events and DB size grows uncontrolled.

Expected results:

Events and DB size can be managed by a utility.

Additional info:

A retention utility is needed for panko.

There's been upstream activity to address this:

https://review.openstack.org/#/c/539579/
https://bugs.launchpad.net/tripleo/+bug/1746514
https://review.openstack.org/#/q/topic:bug/1746514+(status:open+OR+status:merged)

May we please include this in a future maintenance release of OSP12? Creating a BZ to track this activity. I didn't see this code in the latest shipped puppet-panko.

Comment 7 Sasha Smolyak 2018-08-01 12:46:23 UTC

puppet-tripleo code didn't make it to the puddle, so the code is there, but the crone isn't configured.
Running
> sudo docker exec -ti panko_api crontab -u panko -l 
on controller gives " no crontab for panko"

Comment 11 Sasha Smolyak 2018-08-08 10:17:52 UTC

The fix is not in the latest puddle

Comment 15 Sasha Smolyak 2018-08-13 10:50:48 UTC

The latest puddle contains puppet-tripleo-7.4.12-8,
the cron job exists:
[heat-admin@controller-0 ~]$ sudo docker exec -ti panko_api crontab -u panko -l
