Hi team, I'm new to pinot and trying to get logs for troubleshooting using logz. I deployed pinot using k8s, want to make sure are the logs of different components exist in the according pods? like gc-pinot-broker.log and pinotBroker.log. What's the different? How to change the log levels? Is the log seen in kubectl logs same as seen inside the pod log file?

Hi Jinwei, there’s indeed three different level of logs. *

gc-pinot-broker.log

will contain Garbage Collection statistics. Pinot being memory intensive, it is useful to get insights on history of garbage collection. *

pinotBroker.log

is configured with a

info

level on the root logger. *

kubectl logs

 will output the console appender which is configured on a

warn

level for the root logger.

Hi Daniel, thanks for your reply! Yes, I have helm file and trying to put the logs to logz. So does it mean I need to mounting a congfigmap volume to the container and defining the 

<component>.log4j2ConfFile

 helm value? Do we have some examples about this? Thx

What are you using to ship logs to logz?

Is there any docs about the logs?
