Chapter 13. Logging and Monitoring in OpenStack Operations Guide

[N Dillon]

Process monitoring recommendations - the Process Monitoring section mentions the nova-api and nova-compute processes, but does not mention any others (only that "at least one nova-compute" process will be running if the attestation recommended is implemented.

The exact processes should be called out, as well as the number - or how to determine how many should be running (for example, the nova.conf file may limit the number per host, or the filters, or there will be one per vm on the host, or...)

The addition does not address this bug, and was made to the ops-guide, not sec-guide

[Alexandra Settle (alexandra-settle)]

Nathaniel - this bug was targeted to the operations guide (see tags, and original reference points) as you originally reported.

See here: URL: http://docs.openstack.org/openstack-ops/content/logging_monitoring.html

Why did you reopen this for the sec-guide? Could you please clarify what this needs if it is indeed required by the sec guide and not the ops guide?

[N Dillon (sicarie)]

I'm not sure why I mentioned the sec-guide in there, however my original bug was that only a select few items were called out generally. Re-opening was due to:

1) My main issue is that the two examples I see are for disk utilization and plugins and only 5 total general categories are called out (Disk usage, Server load, Memory usage, Network I/O, Available vCPUs) - are these the only things that should be monitored on a nova deployment? Is warning at 80% utilization and critical at 90 applicable across *all* deployments? Or is there a way we can enable a deployer to determine what their threshold should be based on their use-case?

2) The examples are in Nagios - this issue was recently brought up in the sec-guide: do we attest to non-OpenStack ecosystem applications? Should this be referenced in its own section?

3) Object storage links are to Mirantis docs - are these not addressed in the OpenStack documentation? It's fine if they're not, I just want to make sure that is being considered (and we should probably have doc bugs opened on them for that project in that case).

Full disclosure: I'm a huge Nagios fan, I think it should be in there, but I also think that getting coverage on *what* would be more useful, and we need to make sure the Foundation agrees with the position of including/not the outside applications (sec-guide dev has slowed significantly due to this ambiguity). Had I not been on leave, I would have recommended this be merged as a partial-bug until we get the rest of the "what" set up. Apologies for the lateness and lack of clarity!

[Alexandra Settle (alexandra-settle)]

Nathaniel - I understand and see your points. I'd like to move this to the mailing list however. Would you mind if we brought this conversation into the open?

Thanks,

Alex

[N Dillon (sicarie)]

Absolutely!

This issue was fixed in the openstack/openstack-manuals 15.0.0 release.
