    Is there a way to monitor disk space in LEM?

      We are already doing this through Orion but i'm wondering if it can be done through LEM as well?

          There seems to be two ways to interpret this question, so I'm going to tackle both.

           

          First: Can I monitor the LEM's disk space?

           

          Yes!  There's a couple ways to do this.  If you SSH into the LEM, under APPLIANCE you can run a DISKUSAGE command to get an immediate idea of the LEM's current disk usage.

           

          Better yet, there is a template rule that is shipped with the LEM called "SolarWinds Disk Warnings."  This rule fires if any of the LEM's partitions gets over 90% full, and the default action is to send an e-mail.  Paired with another template rule, "Appliance Database Down," you can get alerts about something going wrong in the LEM before it's a big issue, and a timely call to support can get you fixed before anything is really broken.  Both these templates are tagged under "General Best Practice" in the Build --> Rules section of the GUI.

           

          Second: Can I monitor disk space with the LEM?

           

          It's important to understand that the LEM is event driven.  If the system can generate an event that a disk is full, the LEM Agent can capture that event, and a rule can be constructed to take some action, like send an e-mail.

           

          In Windows, there is such an event.  It's ID 2013 in the System log, and it looks a lot like this in the LEM:

          Important: There's no way for the LEM to set the threshold that fires this event on a disk.  That's a setting in the Windows Registry, and by default it fires when the disk reaches 90% full (or less than 10% free, depending on your point of view).  You can change this, but it'd be done in the registry on each system or through a GPO.

           

          There's a template rule for this as well, "Windows Disk Nearly Full."  It's under General Best Practices as well.

            Thanks for the response. I was looking for option B but both are very helpful.
