From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How do you deal with the logs on your servers? (lemmy.ml)

I'm pretty new to selfhosting, but one thing that I know to take seriously is log collection. Since there are a lot of different type of logs (kernel log, application logs, etc) and logs come in many different formats (binary, json, strings) - it's no easy task to collect them centrally and look through them whenever neccessarly.

I've looked at grafana and tried the agent briefly, but it wasn't as easy as I thought (and it might be a too big tool for my needs). So I thought to ask the linuxlemmy community to get some inspiration.

How is the query performance of influxdb for searches in logs for text keywords?

Instead of Influxdb we are using Solr and it is pretty much instantaneous for searching and ordering no matter how large the data is (couple of hundred gigabytes of logs for now). We use it to provide true real-time search in logs for our support team.

It's instant as well in my case, but I don't have a huge amount of logs yet. I'm still figuring out this whole setup and what are it's strength and weaknesses.

I'm using influxdb 1.8 though (which is old), because that's the version shipped with openbsd repos. It crashes fairly often when you perform "illegal" operations, which is annoying. Like, the DELETE FROM command only lets you use the time field in the WHERE clause. Using any other field would crash the DB. I might recompile it from scratch at some point because it lacks too many features from upstream. But for now, it does a decent job, and is really easy to setup (this was the killer feature for me).
