I've become rather frusted witih Grafana Loki lately. It has several
bugs that affect my usage, including issues with counting and
aggregation, completely broken retention and cleanup, spamming itself
with bogus error log messages, and more. Now that VitoriaLogs has
first-class support in Grafana and support for alerts, it seems like a
good time to try it out. It's under very active development, with bugs
getting fixed extremely quickly, and new features added constantly.
Indeed, as I was experimenting with it, I thought, "it would be nice if
the web UI could decode ANSI escapes for terminal colors," and just a
few days later, that feature was added! Native support for syslog is
also a huge benefit, as it will allow me to collect logs directly from
network devices, without first collecting them into a file on the Unifi
controller.
This new role deploys VictoriaLogs in a manner very similar to how I
have Loki set up, as a systemd-managed Podman container. As it has no
built-in authentication or authorization, we rely on Caddy to handle
that. As with Loki, mTLS is used to prevent anonymous access to
querying the logs, however, authentication via Authelia is also an
option for human+browser usage. I'm re-using the same certificate
authority as with Loki to simplify Grafana configuration. Eventually, I
would like to have a more robust PKI, probably using OpenBao, at which
point I will (hopefully) have decided which log database I will be
using, and can use a proper CA for it.
