Description

In this video, I demonstrate setting up annotation queries to help me visualize invalid user login attempts on my servers.

Using Annotation Queries to Link Log Panels with Graphs

The queries I demonstrated in this video were

{filename="/var/log/auth.log"}

count_over_time({filename="/var/log/auth.log"}[1m])

count_over_time({filename="/var/log/auth.log"}[$__auto])

sum(count_over_time({filename="/var/log/auth.log"}[$__auto])) by (host)

The annotation query I demonstrated in this video was,

{filename="/var/log/auth.log"} |= "invalid user"
