Comment 1 for bug 1825798

Given the recent merge of nrpe-external-master relation (lp#1934816), we should revisit this RFE as implementation of additional health checks should now be trivial.

Here are some additional checks which would provide smoother daily operations:

* Pending computer registrations (critical if non-zero)
* Pending security updates (default warning, critical if over some configurable threshold)
* Clients not checking in for X days (critical)

Given this list and the list in original description, it seems it would be helpful if the entire Account Summary page action items/notifications could be exposed to the monitoring/alerting system.
