Is your goal to monitor for issues in the Fleet server cc < Noah Talerman>

SK · Answer

< mikermcneil> yes that would be the idea if you have different fleet servers for load balancing you would need to go to all individually to look at the logs I was wondering if there was a way to centralize them

Hi < SK> Fleet provides documentation for monitoring Fleet and working with Fleet server metrics here Please let me know if your use case doesn t fall under the provided information in these docs

SK · Answer

Hey < Noah Talerman> we are already gathering these metrics but I was thinking more like when you want to debug if a host is trying to connect that you can easily look for the IP of that host in the logs at this moment I would need to login to each separate fleet server and query the journalctl I was wondering if the journal also writes to syslog or another log file

Hey < Noah Talerman> thanks for your response I do not have AWS or Kubernetes so will need to think of another onprem solution Does fleet right it s logs similar to journalctl to a file that maybe I don t know about

I believe Fleet doesn t write its logs to a file Verifying that answer now

Noah Talerman · Answer

Update Fleet writes server logs to `stderr` which can be written to a file You can write `stderr` to a file by running this command in a Unix shell `fleet serve 2 gt stderr txt`

Hey < Noah Talerman> just figured out the logs are already written out to ` var log daemon log` face with rolling eyes zipper mouth face so no need for extra configuration open mouth Maybe add this to the documentation for future reference

Noah Talerman · Answer

Ah Thank you for letting me know Are you sifting through multiple `var log daemon log` files on each machine serving your Fleet instances

SK · Answer

Plan is to ship it over to a central log manager now that I know where the logs are
