journaldtail
This is a small PoC to explore how to ship journald logs to grafana loki. This code is currently work in progress.
Any comments and suggestions are welcome.
I made this project since the promtail community is not sure if promtail will support journald. (see: grafana/loki#26 (comment) )
Building
To build this, you'll need cgo and the systemd headers installed - for example, on a Debian based system, apt-get install libsystemd-dev.
Journal fields
When you import Journald logs to loki, you'll see a large number of log labels. Its worth reading the systemd journal fields documentation to get a feel for what is available to you.
ToDo
- Fix logging infrastructure in code
- Enable configuration via flagext
- Support relabeling config like in promtail
- Tests
- Build and release pipeline
- Documentation
- Store journald cursor position on disk to allow restart of journaldtail
