Description
Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1390694
We need a simple script that users can run that can collect the following information:
1) Disk consumption and availability of the following directories:
/var/lib/pulp/
/var/lib/mongodb/
/var/lib/pgsql/
2) Disk speed using hdparm:
- hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 31332 MB in 2.00 seconds = 15689.05 MB/sec
Timing buffered disk reads: 466 MB in 3.01 seconds = 154.99 MB/sec
Not all Katello servers will have this installed so just automatically install it if you have to
3) Table sizes:
https://gist.github.com/mccun934/e93358be72902aa67dc450cb4f7c4574
cat tablesizes.sql | sudo -u postgres psql -d foreman
4) Table counts:
select count() from hosts;
select count() from dynflow_actions;
select count() from dynflow_steps;
select count() from katello_repositories;
A second phase would be to take these #s and calculate an estimated upgrade time but just gathering this data will be helpful and can be included in foreman-debug if possible.
A name like:
- katello-size-report
would be easy to remember
