To celebrate Batman's 75th Anniversary and provide a fun challenge, the team created a custom Agent check for Datadog to visualize the Batman Curve. The Bat-signal can be sent to Datadog by plotting an equation resembling Batman and submitting coordinates on a schedule. Users can replicate this by installing the custom Agent check and combining metrics in one graph, averaging `dd.batman.top` and `dd.batman.bottom` metrics for a signal. By using Datadog's free trial, users can create cool graphs and gain actionable insights into their infrastructure performance. The team invites users to try it out on Batman Day.
