Hi @thermallife,

Welcome to the :grafana: community forum !!

You can find the grafana logs using the command;

docker logs container-name

Where,

container-name

is the name you name for e.g. grafana or maybe used grafana8 etc.

Further information which I found via;

When running grafana via docker image the logs by defaults output to the console.

You can change that by setting the environment variable GF_LOG_MODE to console file if you want the logs to be written to both, the console and a file. Set it to file otherwise. This works for docker-compose.yml, docker run or can be set at a later point of time from within the grafana-container by editing its grafana.ini

Additionally: You might have to set the environment variable GF_LOG_LEVEL in addition to GF_LOG_MODE as your container might crash otherwise: GF_LOG_LEVEL=info

The different log modes to choose from can be found in Grafana’s precise documentation

Hello

Thank you in advance for all the support you are giving!!

I do have the exact same issue and I worked my way through the documentation. Below you can find my the grafana relevant docker compose code.

I would like to increase security and add grafana to my fail2ban list. For this I need the log files.

The log files just do not appear. Not in the defined volume, neither in the container itself at the specified location (I went an checked). I know that the GF_LOG_... does have an effect as I can silence the console output when I eliminiate console.

The console output (further down) also, in my eyes, confirms that everything seems in working order…

Can anyone help me out?
Thank you very much!

Hi @akreaxun,

Sorry, I do not understand your question correctly. Because looking at your logs, it appears that the docker deployed the grafana container correctly.

What exactly do you want to add more? please explain

Thanks.
