Uh oh! Something went wrong!

Please perform the steps outlined in the error message above

If you're still having trouble, gist the log files
and come see us in our Slack community:

You can access Hubot logs at /var/log/st2/st2chatops.log.

Other StackStorm logs are also stored in /var/log/st2/.

Thanks @humblearner. Looks like there is an actual bug in centos 7.

[lakshmi-kannan]

It looks like we get logging on centos7 for python processes because of explicit app logging. Let me confirm with @enykeev.

[lakshmi-kannan]

I am right and this is a blocker to enable app level logging for hubot. https://github.com/github/hubot/pull/1164

At the moment, for systemd (CentOS7, Ubuntu16) the only way is:

journalctl --unit=st2chatops

Should be closed with c590deffdc11a325352c0c04a4d2635f9e3325c4, but I've only tested on Ubuntu 16.04 so far.

@blag The change mentioned (which is BTW a direct push to master and not a PR :-1: ) just brings workarounds for self-check script, but doesn't fix the root cause.

Eg. ChatOps Log Does Not Exist On CentOS7/Ubuntu16 is still an issue.

[LindsayHill]

Newer systemd versions allow specifying a log file, but this won't work for Ubuntu16 or RHEL 7.

There are some ugly workarounds, but they're ugly. No obvious good solution here.
