Description Qiaoling Tang 2019-03-27 01:51:49 UTC 
+++ This bug was initially created as a clone of Bug #1690232 +++

Description of problem:

Per https://bugzilla.redhat.com/show_bug.cgi?id=1651884#c4, when  LOGGING_FILE_PATH=console, should use "oc logs $fluentd-pod" to view fluentd pod logs, but in fact, it doesn't show pod logs. 

Set LOGGING_FILE_PATH=console makes fluentd store it's own logs to "/opt/app-root/src/console"


Version-Release number of selected component (if applicable):
logging-fluentd-v3.9.74-2

How reproducible:
Always

Steps to Reproduce:
1.Deploy logging
2.Set LOGGING_FILE_PATH=console in ds/fluentd, then check fluentd pod logs:
$ oc set env ds/logging-fluentd LOGGING_FILE_PATH=console

[root@qe-anli39-master-etcd-nfs-1 ~]# oc exec logging-fluentd-ds6zq env |grep LOGGING_FILE
LOGGING_FILE_PATH=console
LOGGING_FILE_AGE=10
LOGGING_FILE_SIZE=1024000
[root@qe-anli39-master-etcd-nfs-1 ~]# oc logs logging-fluentd-ds6zq
=============================
Fluentd logs have been redirected to: console
If you want to print out the logs, use command:
oc exec <pod_name> -- logs
=============================

3.

Actual results:


Expected results:
Should be able to use "oc logs $fluentd-pod" to view pod log when LOGGING_FILE_PATH=console

I don't understand why the 3.x releases have this problem with LOGGING_FILE_PATH=console - this should have been fixed a long time ago - is this a regression?

Note that the implementation in 4.x is completely different, and LOGGING_FILE_PATH=console was broken in 4.x for a completely different reason.
Comment 5 Anping Li 2019-04-22 13:36:04 UTC 
The fluentd can be found in console using version v3.9.78
