Bug #8168
closed
If syslog service is stopped, it is not restarted automatically by rudder-agent, so agent doesn't report anything
Added by Nicolas CHARLES over 8 years ago. Updated over 2 years ago.
Description
On a sles11, if syslog-ng is stop, running the agent won't restart it
So the node doesn't report a thing, and the node is in the "no answer" state - and won't auto-heal
we should automatically restart the appropriate syslog deamon when none is running
Fails at least on SLES11 rudder 3.1, but most likely on previous version of Rudder

- Priority changed from 1 (highest) to 2
This is easily fixed by adding a call to "service_ensure_running" in the common promises.

- Target version changed from 3.1.10 to 2.11.21
Actually, this was never implemented :/

Ha - i'm hitting an unexpected issue: how do I know which syslog service I shall start in priority ?
For instance, if a system is provisionned with ksyslog, and then syslog-ng is installed, how can I detect that syslog-ng has precedence over ksyslog ?
I could service_check_running on each of syslog_ng, rsyslog, syslog, and if any of them is up and running don't do anything, else start the most complex one ? (syslog-ng > rsyslog > syslog)
What do you think of it ?

This order is subjective, so we shouldn't do that.

On SuSE, this is quite easy because there is a config file in /etc that determines which syslog is in use.

Not that easy on SuSE either (with the "syslog" pseudo-service which point to the actual logging service), because service_ensure_running("syslog") ends up greping the name of the service in ps output (and does not find it because syslog is never running), and therefore tries to start it on every run.

- Severity changed from Major - prevents use of part of Rudder | no simple workaround to Critical - prevents main use of Rudder | no workaround | data loss | security
- User visibility set to Operational - other Techniques | Technique editor | Rudder settings
We are setting it to "critical" because data are lost (no reports during the period).

The only easy fix is for SLES11 (syslog pseudo-service) on Rudder 4.1 (because of the new service methods). All other cases require some more thinking about the issue.

- Target version changed from 3.1.19 to 3.1.20
Updated by Alexis Mousset over 7 years ago
- Effort required set to Medium
- Priority changed from 71 to 70
This is a medium issue because we do not know how to properly detect the service to start in the general case.

Let's ensure running all syslog services present.
This will work in all the cases except when someone installs 2 syslog services and doesn't configure them to work together.
