SplunkUF is not forwarding logs from the Kubernates container

问题

I deployed Splunk Forwarder in my kubernetes cluster using this blog.

http://jasonpoon.ca/2017/04/03/kubernetes-logging-with-splunk/

I have 4 files at

/opt/splunk/etc/system/local

inputs.conf

server.conf

limits.conf

outputs.conf

my inputs.conf looks like this.

[default]
host = testtest

[monitor:///usr/local/tomcat/logs]
whitelist=test.log|.log_WHITELIST_|test
index= abc
sourcetype=log4j
[splunktcp://9997]
compressed = false

I am not able to get the log in Splunk UI. when I am deploying it as side car. but If I use same docker image locally but putting dummy logs file. i can see the logs. Then why it is not working with kubernates?

I have checked the splunkd.log as well.

/opt/splunk/var/log/splunk # tail splunkd.log

Any suggestion how to fix this. Stuck here for days. Do I have to open any port under kubernates? although I can ping splunk server from the splunk container.

回答1:

I would highly suggest looking for the alternatives for forwarding Kubernetes logs to Splunk:

Open Source Free version of Splunk Connect for Kubernetes - this is a recommended by Splunk option for forwarding logs
Monitoring Kubernetes with Collectord by Outcold Solutions (I represent this company) - this is a proprietary software, takes 10 minutes to set up to forward logs and collect metrics.
