/var/log/daemon.log

2) Status of Docker containers fron the Fuel master node:
dockerctl check all

3) Status of Galera cluster:
mysql ­e "SHOW status LIKE 'wsrep%';"

4) OCF scripts
The content of the following directory from the Controller nodes:
/usr/lib/ocf/resource.d/

IIRC the entire /var/log must be there so it's required to investigate why they aren't.

[Georgy Kibardin (gkibardin)]

I think we need to recheck /var/log since we've switched to Timmy.

[Maksim Malchuk (mmalchuk)]

We need to think TWICE because the /var/log/atop/ (for example on production) could be several gigabytes/terabytes in size!

[Dmitry Pyzhov (dpyzhov)]

We switched to timmy tool for logs gathering. Moving the bug to them.

[Georgy Kibardin (gkibardin)]

My bad about atop, I've completely forgotten about its exclusion :(

[Anton Chevychalov (achevychalov)]

When we switch to timmy we loose all our code related to shotgun. So currently all we did last years are broken.

[Dmitry Sutyagin (dsutyagin)]

@Anton Chevychalov - if you have a specific issue you need a fix for - please create a bug. I understand that if your code relied on Shotgun's file structure then it won't work out of the box with timmy's data, but it sould be possible to remap your logic to read Timmy's output files, the content will be the same of the most part, only filenames and folders have changed. This issue is not relevant in scope of this bug.

[Dmitry Sutyagin (dsutyagin)]

If this bug is still relevant please update what the current needs are - I believe some of the items are now invalid, others do not look reasonable (like "dockerctl check all" which can take really long time)

[Alexander Rubtsov (arubtsov)]

The request is still relevant both for Shotgun (for 7.0) and Timmy (for 9.0)

I have only 1 clarification to the initial list:
2) "dockerctl check all" is relevant for MOS 7.0 only. The "fuel-utils check_all" command is used in MOS 9.0

Fix released for 9.x
