Hey, I was trying to install Grafana-Loki. So, I have a question regarding promtail job. path: /alloc/logs/* this one only gives about logs promtail job. In my nomad, I have other jobs and I would like to push their logs, in that case, which path should I use? Or is there any better way to push other job logs?
