Inverse a monitor - "Fail" when a condition is met

seigniory

I have a few windows services that by policy should never be running.  I'd like to monitor them such that when a service is stopped, the monitor is green.  If the service ever starts, I'd like to get alerted as I would if something else went down.

Also if possible, I'd like to have a monitor alert me only if the free space on a disk volume is ever *greater* than, for example, 10GB.

Doable?  I'm still running 9.

For your Free Drive Space question, you would use a similar method.  The only problem is that the Host-MIB does not provide free space.  It provides Total Space and used Space.  On the other hand, the Informant MIB provides Free Megabytes (see http://ipmsupport.solarwinds.com/mibs/INFORMANT-STD/item.aspx?id=lDiskFreeMegabytes).  Here's what you would need to do:

1. Download and SNMP Informant Standard on the remote system you wish to monitor from here:

http://www.wtcs.org/informant/download.htm

• Go back to the Add New Monitor page and run the Custom SNMP (Wizard).
• Ensure that the address and Community name are correct and enter the following OID: 1.3.6.1.4.1.9600.1.1.1.1.20
• Click 'Select' next to the drive you wish to monitor.
• For "Comparison Rules" select "Pass if Value matches a set of Boolean Rules" and set it to less than  10000
• Click 'Next'

As a result, Monitor will only pass if FreeSpace on system is less than 10 000 Megabytes (approx 10 Gigs)
