I hope you enjoy these advent calendars leading up to Christmas.

Now onto this week’s update information.

Customized (expression) graphs can now be added to GraphBoard

"GraphBoard" is an interactive feature that lets the user freely arrange arbitrary role and service metrics graphs.

With this week's update, we’ve increased the number of types of graphs that can be added to this GraphBoard. Customized graphs (expression graphs) can now be added!

  • Overlay server load statuses for the current week and the previous week and display as one graph
  • Display the calculated maximum value/average value/minimum value of the server load belonging to a particular role

Customized graphs are extremely useful and allow you to implement the above procedures by describing the function expression. We believe that putting this to use will be even easier than before.

Displaying customized graphs is an experimental feature. For more details, check out the following help pages.

You can now configure the max number of attempts for host/service metric monitors

As you can see in the image above, the "Max number of attempts before an alert is triggered" can be configured with host metric and service metric monitors.

Up until now, only the monitoring of “Duration” (average of the past n minutes) was supported. For example, if you wanted to have an alert occur when a threshold of 5 is consecutively exceeded, you would configure the following.

  • Threshold of 5
  • Duration of 3 minutes

However, with this configuration, not only would a progression of 756 (a 3min average of 6) lead to an alert occurrence, but also for a progression such as 1161 (in this case, also a 3min average of 6). For this reason, sometimes unintentional alerts would occur.

With this update, you can eliminate cases such as the one above by utilizing the newly added "max_check_attempts". We hope that you can use this feature together with "Duration” monitoring to eliminate unintentional alerts.
