Solarwinds & Cisco Live! Barcelona
Join us from the 29th of January to the 2nd of February at Cisco Live 2018 in Barcelona, where we will continue to show how monitoring the network with SolarWinds will keep you ahead of the game. At our booth (WEP 1A), we will demonstrate how SolarWinds network solutions can help. As a bonus, we are also hosting a pre-event webinar - Blame the Network, Hybrid IT Edition with our SolarWinds Head Geek™, Patrick Hubbard on January 24th - GMT (UTC+0): 10:00 a.m. to 11:00 a.m. There's still time to RSVP.

Configure exclusion policies

Updated: 10-19-2016

Policies define constraints for the Recommendation Engine per selected virtual objects in your virtual environment. These constraint policies include exclusion policies for excluding objects.

Exclusion policies specify virtual objects to exclude from generated recommendations. You can set up an exclusion policy for specific virtual objects including virtual machines, hosts, clusters, and datastores.  When creating an exclusion policy, you select monitored virtual objects in you environment from generating recommendations. For example, add a constraint to block recommendation generation for a specific VM used for new software testing.

Important: A policy can affect other recommendations. After creating a policy, all active and scheduled recommendations are recalculated.

For example, you may not want to have recommendations run against a VM strictly used for testing software installations in your environment. These VMs may be kept under-allocated with limited capacity to specifically test the effects of installed software on servers of that type. You may also want to keep the VM on a specific host and cluster, adding a disallow action for moving the VM. This refines the Recommendations Engine to focus monitoring on important servers in your environment and keeps the recommendations from filling with actions for this VM.

Create exclusion policies

The following example excludes a VM from recommendations monitoring:

  1. Click My Dashboards > Virtualization > Recommendations. Click Recommendation Settings.

  2. Click Policies.

    The policies page displays with all current exclusion policies listed.

  3. Click Add Exclusion.

    A page displays with VMs displayed based on the selected filter.

  4. To filter and display specific VM types, select a filter: Virtual Machine, Cluster, Host, or Datastore. The list of available VMs displays for the object type.

  5. Select the VMs from the list to exclude from recommendations.

    For this example, you would select the testing VM. If a VM has an exclusion policy, it displays in the list.

  6. Optionally, you can expand the Policy Description and add notes for the exclusion.

    These notes can be useful for network administrators managing exclusions. For this VM, you could add the note "Testing VM for software installation testing. Excluded by Network Admins from recommendations."

  7. Click Create Policy.

    The selected VM no longer will generate recommendations. As you test your installs, recommendations no longer generate warning of resource underallocation or capacity issues.

Remove a VM from an exclusion policy

If you have a VM with exclusions and want to start generating recommendations, you can edit the exclusion policy and remove the VM:

  1. Click My Dashboards > Virtualization > Recommendations. Click Recommendation Settings.

  2. Click Policies.

    The policies page displays with all current exclusion policies listed.

  3. Locate and select the exclusion policy from the list.

  4. Deselect the checkbox for the VM.
  5. Click Save Policy.

    Recommendation begin tracking and triggering for the VM again.
