Automating OpsMgr Part 11: Configuring Group Health Rollup

Written by Tao Yang

OpsMgrExntededIntroduction

This is the 11th instalment of the Automating OpsMgr series. Previously on this series:

Since I have already covered how to create, update and delete OpsMgr groups using the OpsMgrExtended module, the last thing I want to cover on this topic is how to configure health rollup for the groups.

The runbook I’m demonstrating today was based on the PowerShell script in the OpsMgr Group Health Rollup Configuration Task MP which I published yesterday. As I explained in the previous post, because instance groups do not inherit any dependency monitors for their base class, when OpsMgr admins creating groups in the console (which can only be instance groups), they are shown as “Not monitored”:

By creating an agent task to create health rollup dependency monitors (in the OpsMgr Group Health Rollup Configuration Task MP), I have provided a more user friendly way for OpsMgr users to configure health rollup for groups, but this task won’t help us when we are designing an automation solution. Therefore, I have written a SMA runbook based on the script I developed for the MP.

Runbook: Configure-GroupHealthRollup

This runbook requires the following input parameters:

  • GroupName: Required parameter. Name of the group (note, this is not the display name you see in the OpsMgr console)
  • Algorithm: Required parameter. The algorithm to use for determining health state. Possible values: ‘BestOf’,’WorstOf’,’Percentage’.
  • Percentage: The worst state of the specified percentage of members in good health state. This parameter is only required when the specified algorithm is ‘Percentage’. Optional parameter, default value is 60 if not specified.
  • MemberUnavailable: The health state when the member is unavailable. Possible Values: ‘Uninitialized’, ‘Success ‘,’Warning’, ‘Error’. Optional parameter. If not specified, the default value is “Error”.
  • MemberInMaintenance: The health state when the member is in maintenance mode. Possible Values: ‘Uninitialized’, ‘Success ‘, ‘Warning’, ‘Error’. Optional Parameter. If not specified, members in maintenance mode will be ignored.
  • ManagementPackName: The Management Pack name of which the monitors going to be saved. This is only going to be used when the group is defined in a sealed MP.’
  • IncreaseMPVersion: Boolean optional parameter. Specify if the management pack version should be increased by 0.0.0.1.

Conclusion

In this post, I have demonstrated how to configure OpsMgr group health rollup by creating dependency monitors using a SMA runbook. As I mentioned in part 4, I was going to dedicate few post for a creating and managing groups mini series. This post would be the last post for this managing groups mini series. To summarise, on managing groups, I have covered the following aspects:

  • Creating new empty groups (Part 4)
  • Adding Computers to computer groups (Part 5)
  • Adding monitoring objects to instance groups (Part 6)
  • Incorporated the runbooks from part 5 and 6 into the new version of the OpsMgrExtended module (part 7)
  • Updating group discoveries (Part 9)
  • Deleting Groups (Part 10)
  • Configure Group Health Rollup (Part 11, this post)

Starting from next post, I will start talking about how to create monitors, rules, etc. So it should only get more interesting from now on.

This is all I’m going to share for today. Until next post, happy automating OpsMgr!
