Again, please update your agent to minimize the impact of the possible future .io domain failure. Check out last week’s entry for the content of the agent updates.

AWS Integration now supports NLB

The recently released AWS Network Load Balancer (NLB) is now also supported in AWS Integration.

Check out the following help page for more information on how to use it.

Graph guide now uniformly displayed

The guide which is displayed when hovering over a graph in the host detail screen, service details screen, etc. is now displayed in all other graphs within the same screen.

We think this will be handy for tasks such as investigating server resources.
