Solution

The cause of this defect (and the associated exception) is that somewhere in the environment, there is a probe or probes which do not have the "Description" field populated. You can view this in Infrastructure Manager - click on a robot and look at the list of probes on each robot. You will see a "Description" column - for example, the Description for the controller probe is "Robot process and port controller."?

Very likely this is caused by a custom probe (as all official Nimsoft probes should have this field populated) - so I'd start by checking any robots where you have a custom probe running and see if the Description column is blank on any of them.?

If so, you have two options:?

1. Right-click the probe and select Edit... and change the description in IM?
2. Right-click the probe package in the Archive, and select Edit... then change the description in the Package Editor, and then re-deploy the probe to the necessary robot(s).?

We will be fixing this in a future release so that we won't require every probe to have a description set - it is not uncommon for custom/field-developed probes to have nothing set for this - but in the meantime if you're able to set the Description for all probes in the environment it would resolve the "unable to retrieve health monitor status" issue.?
