This looks like a straightforward permissions error; which user owns the access log file (and what are the file's permissions), and under which user does the exporter run? Does it work when you're removing the CapabilityBoundingSet directive from the systemd unit?
@martin-helmich I just ran into the same issue. The prometheus-nginxlog-exporter service was running fine for it's first 24 hours, all of the sudden Nginx rolled the files and created a new main log file and the prometheus-nginxlog-exporter stopped because the file could not be accessed, permissions denied...
I've tried your solution of removing CapabilityBoundingSet and that works perfect! Thanks! Note: When doing so you may not forget to:
Reload the deamon: systemctl daemon-reload
Restart the service: sudo systemctl restart prometheus-nginxlog-exporter
If you use k8s to deploy this exporter, one possible solution is to run the exporter container as the nginx log files owner by applying security context: https://kubernetes.io/docs/tasks/configure-pod-container/security-context/
solution of removing CapabilityBoundingSet and that works perfect!
@dirkvranckaert, I also end up with removing this directive.
removing the CapabilityBoundingSet directive from the systemd unit
@martin-helmich, can you share original reason why this directive was added to the systemd unit? Has anybody confirmed this exporter working with this directory left in the systemd unit?
