Hi everyone, I’ve been building my own log search server because I wasn’t satisfied with any of the alternatives out there and wanted a project to learn rust with. It still needs a ton of work but wanted to share what I’ve built so far.
There’s a lot of features I plan to add to it but I’m curious to hear what people think and if there’s anything you’d like to see out of a project like this.
Some examples from my lab environment:
events view searching for SSH logins from systemd journals and syslog events:
counting raw event size for all indices:
performance is looking pretty decent so far, and it can be configured to not be too much of a resource hog depending on use case, some numbers from my test install:
raw events ingested: ~52 million
raw event size: ~40GB
on disk size: ~5.8GB
Ram usage:
not running searches ingesting 600MB-1GB per day it uses about 500MB of ram
running the ssh search examples above brings it to about 600MB of ram while the search is running
running last example search getting the size of all events (requires decompressing the entire event store) peaked at about 3.5GB of ram usage
That’s a good point. Mind that in most production environments you’d be firewalled rather hard (especailly when it comes to logs processing which oftentimes ends up having PII). I wouldn’t trust any service that tries to use DoT or DoH in there that I couldn’t snoop on. Many deployments nowadays allow you to “punch” firewall holes based on the outgoing dns requests to an allowlisted domain, so chances are you actually want to use the glibc resolver and not try to be fancy.
That said, smaller images are always good in my book!

Oh I wasn’t using it as a full recursive resolver - just reading the resolv.conf set by docker and sending requests
