120de1dca9 zephyr: Write out unix timestamp in check, as check_cron_file expects. 
A follow-up fix to 8bc26aab08.

8577adcf2e cron: Remove unused STATE_FILE environment variable. 2022-06-22 12:07:38 -07:00
Alex Vandiver
8bc26aab08 nagios: Switch check_user_zephyr_mirror_liveness to run via cron. 
This check loads Django, and as such must be run as the zulip user.
Repeat the same pattern used elsewhere in nagios, of writing a state
file, which is read by `check_cron_file`.

41deef40cf nagios: Switch to generic check_cron_file for queues and consumers. 
These share a common root; 91da4bd59b duplicated the code, but
didn't move the existing uses to the new utility.

8fbde9b8c5 nagios: Only run check_fts_update_log on one PostgreSQL host. 
The data is the same in the table in all replicas -- there is no need
to alert on all of them.

499284d2fd nagios: Split postgresql into primary and replica. 
Replication checks should only run on primary and replicas, not
standalone hosts; while `autovac_freeze` currently only runs on
primary hosts, it functions identically on replicas, and is fine to
run there.

Make `autovac_freeze` run on all `postgresql` hosts, and make
standalone hosts no longer `postgres_primary`, so they do not fail the
replication tests.

Alex Vandiver
2c90c7a010 nagios: Switch check_remote_arg_string queue checks to consumer checks. 
These style of checks just look for matching process names using
`check_remote_arg_string`, which dates to 8edbd64bb8.  These were
added because the original two (`missedmessage_emails` and
`slow_queries`) did not create consumers, instead polling for events.

Switch these to checking the queue consumer counts that the
`check-rabbitmq-consumers` check is already writing out.  Since the
`missedmessage_emails` was _already_ checked via the consumer check, a
duplicate is not added.

83c82c8e15 nagios: Adjust load alerting by hostgroup. 
Even the `pageable_servers` group did not page for high load -- in
part because what was "high" depends on the servers.  Set slightly
better limits based on server role.

d9d0014fb4 nagios: Rename zmirror_main into zmirror hostgroup. 
`zmirror` itself was `zmirror_main` + `zmirrorp` but was unused; we
consistently just use the term `zmirror` for the non-personals server,
so use it as the hostgroup name.

70c36985b4 nagios: Remove frontends from redis group. 
The Redis nagios checks themselves are done against `redis` +
`frontends` groups, so there is no need to misleadingly place
`frontends` in the `redis` hostgroup.

08127086bc nagios: Remove misleading "staging_frontends" from standalone. 
No services are tested for the `staging_frontends` hostgroup, so this
does not alter the checks.

4c17f2bccc nagios: The frontends hostgroup now includes prod and staging frontends.

c74f195fba nagios: Split AWS and non-AWS hosts, for ntp checks. 
The non-AWS hosts cannot use the AWS ntp server for their check.

872efdee58 nagios: Fold single- and multitornado_frontends back into frontends. 
5abf4dee92 made this distinction, then multitornado_frontends was
never used; the singletornado_frontends alerting worked even for the
multiple-Tornado instances.

Remove the useless and misleading distinction.

3741c1c034 puppet: Switch to checking time against the AWS timeserver. 
Since this is what chrony is sync'ing to, it lessens the chance of
spurious firings of this alert.

e9ba9b0e0d zulip-ec2-configure-interfaces: Remove. 
Our current EC2 systems don’t have an interface named ‘eth0’, and if
they did, this script would do nothing but crash with ImportError
because we have never installed boto.utils for Python 3.

(The message of commit 2a4d851a7c made
an effort to document for future researchers why this script should
not have been blindly converted to Python 3.  However, commit
2dc6d09c2a (#14278) was evidently
unresearched and untested.)
