Tim Abbott 4e10424512 Migrate check_worker_memory to zulip/. 2016-04-05 13:27:04 -07:00
Tim Abbott 59b46278be Move check_queue_worker_errors into subdirectory. 
This fixes an issue where this worker wasn't even being installed
properly in a way that sets us up for doing further reorganization of
the Zulip Nagios plugins.

Tim Abbott 2adf6d822f puppet: Fix process_queue command lines to use the new argument style. 
cd2348e9ae broke installing Zulip in
production since it didn't correctly update the puppet configuration
to call the process_queue script using the new argument format.

This commit isn't ideal in that I'd prefer to not require updating
puppet in sync with the actual running code, but we don't have a great
mechanism for doing that.

Fixes #586.

Zev Benjamin 286bd3005d nagios: Disable idle transaction checks 
We apparently still have some process that occationally sits idle in a
transaction for a while, which makes this alert super noisy.

Zev Benjamin f7b64827e4 nagios: Don't check txn_time on trac 
Doing so requires superuser privileges because check_postgres.pl only connects
to one database for that action.  We could theoretically work around this, but I
don't think it's worthwhile for non-production DBs.

Zev Benjamin 49f2657c8d nagios: Add check_postgres checks for the trac and wiki databases 
We don't do the sequence check because that requires read access to the database
itself, which the zulip user doesn't have.

Zev Benjamin c045644097 puppet: Run check_ntp_time against an NTP pool instead of time.mit.edu 
MIT implemented NTP rate-limiting to defend against on-going reflection attacks,
which was causing our nagios checks to fail intermittently.  When the attacks
die down or when external sites fix their NTP configurations, checking against
time.mit.edu will stop failing.  However, there also isn't much of a reason to
stick with checking against a single server.
