Annotation Queries Linking the Log and Graph Panels

Video Lecture

Using Annotation Queries to Link Log Panels with Graphs Using Annotation Queries to Link Log Panels with Graphs Annotation Queries Linking the Log and Graph Panels

Description

In this video, I enhance the quick dashboard that I created in the LogQL section and add an annotation query to help me visualize invalid user login attempts much better.

Using Annotation Queries to Link Log Panels with Graphs

The queries I demonstrated in this video were

{job="varlogs"}

and

count_over_time({job="varlogs"}[1m])

The annotation queries I demonstrated in this video were,

{job="varlogs"} |= "invalid user"

and

{job="varlogs"} |= "invalid user" != "level=info"

This final annotation query could also have been written as,

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

You have many options.
