Hi Splunk Team,
I have deployed Splunk App for Infrastructure and it is working well (essentially it deploys SCK to my server). I have been trying to update my ConfigMap called "sck-rendered-splunk-kubernetes-logging" to setup my source.container.conf file as follows:
<source>
@id containers.log
@type tail
@label @splunk
tag tail.containers.*
path /var/log/containers/*.log, /var/lib/kubelet/pods/*/volumes/kubernetes.io~empty-dir/emptydir*/.*/*.log
exclude_path ["/var/log/containers/fluentd*"]
pos_file /var/log/splunk-fluentd-containers.log.pos
tag kubernetes.*
path_key source
read_from_head true
<parse>
@type regex
expression /^(?<log>.*)$/
time_key time
time_type string
time_format %Y-%m-%dT%H:%M:%SZ
</parse>
</source>
Please take a look at the entry from the Path line above (copied here):
/var/lib/kubelet/pods/*/volumes/kubernetes.io~empty-dir/emptydir*/.*/*.log
We are not correctly receiving legacy app logs in Splunk, which was the purpose of the above entry to the Path config.
To give some more info on our file structure, we have empty-dir mounted to legacy logging applications which is mounted to /opt/apps/weblogs on the pod and /var/lib/kubelet/pods on the Node (server) itself.
Here's an example of the absolute path to an application 's legacy logs that are hosted on a node:
/var/lib/kubelet/pods/e36c6c23-325b-4e1e-b11e-26ff5abffd17/volumes/kubernetes.io~empty-dir/emptydir-my-test-app-rd-mytestapp/mytestapp
Here's a look at the filesystem mounted inside of the pod:
sh-4.2$ cd /opt/apps/weblogs/
sh-4.2$ ls
andrew.log mytestapp
sh-4.2$ ls mytestapp
mytestapp.log other_directory
With our current path (pasted once more below this), we are able to tail the file "andrew.log" in Splunk, but we are not able to tail log files from mytestapp/ and downwards through the filesystem . Can you give some advice on how to update our path in the conf file, or any other place (e.g. the regex) to help us effectively ingest logs from both andrew.log (ie /opt/apps/weblogs) + any .log file that lives in mytestapp or recursively below that (other_directory and beyond)?
