What kind of issues that you see where you have to step in and intervene? We have been running Loki for a long time, and it barely requires any manual intervention apart from version upgrades.
One thing that I find hard is configuring the retention time. The docs are unclear and there are about 3 configuration parameters involved. It scares me as a non expert because I don't want to fill up all disk space but also don't want to keep too little logs.
Yes I agree with rootsu, we have been running Loki in production for over two years and rarely have to step in and fix things. It's very stable and performant.
