This article outlines methods to get agent logs from different environments when Instana support/engineering requests this information. This information helps to troubleshoot the issue in hand.
Getting "agent logs" for Linux Host:
The agent logs are located at <instana_install_dir>/data/logs
Simply zip up this directory and post the zip file to the ticket.
Getting "agent logs" for Windows Host:
The agent logs are located at:
C:\Program Files\Instana\instana-agent\data\log
Simply zip up this directory and post the zip file to the ticket.
Getting "agent debug logs" for Linux Host:
- Stop the agent (/bin/stop.sh)
- Wipe the logs (delete all files in /data/logs)
- Set log level to DEBUG (change the severity in the configuration file
following the instructions here:
https://docs.instana.io/quick_start/agent_configuration/#agent-logging-configuration
- Start the agent (/bin/start.sh)
- Reproduce the issue
- Zip up the logs (in /data/logs) and post the zip file to the ticket
Getting "agent debug logs" for Windows Host:
- Stop the agent (C:\Program Files\Instana\instana-agent\bin\stop.bat)
- Wipe the logs (delete all files in C:\Program Files\Instana\instana-agent\data\log)
- Set log level to DEBUG (change the severity in the configuration file
following the instructions here:
https://docs.instana.io/quick_start/agent_configuration/#agent-logging-configuration
configuration file location C:\Program Files\Instana\instana-agent\etc\org.ops4j.pax.logging.cfg)
- Start the agent (C:\Program Files\Instana\instana-agent\bin\start.bat)
- Reproduce the issue
- Zip up the logs (in C:\Program Files\Instana\instana-agent\data\log) and post the zip file to the ticket
Getting "agent logs" from a container
By default, the Instana Agent will log to <instana_install_dir>/data/log/agent.log, which will also be rotated should the file grow too large. If you are running the agent in a container, it logs to the console instead, which is managed by Docker and accessible via docker logs. You can run the below command to get the logs for the container:
docker logs <container>
Getting "agent logs" from Kubernetes namespace:
Could you please use the below script to get the logs of all instana-agents in your cluster. It will output all logs in directory "instana-agent-logs" which can be zipped and sent back to us.
Content of the script is below:
mkdir instana-agent-logs
for p in $(kubectl get pods --namespace instana-agent | cut -f 1 -d ' '); do
if [[ $p != "NAME" ]]
then
kubectl logs $p -c instana-agent --namespace instana-agent > instana-agent-logs/$p-instana-agent.log
kubectl logs $p -c instana-agent-leader-elector --namespace instana-agent > instana-agent-logs/$p-instana-agent-leader-elector.log
Fi
Getting logs for troubleshooting an on-prem server related issue:
Please provide the:
- Output of instana-debug and
- Archive generated by the command that is documented here:
