CA Performance Management
detects the following changes to the device:
  • System name
  • System contact
  • Device type
  • Location
  • Vendor
  • Device description
  • Device model
Changes to device attributes can result in changes to the groups and device collections that a device is in. Changes to groups and device collections can potentially add or remove monitoring profiles. Running the discovery profile does not evaluate or update the metric families for the device.
For information about how to update metric families for the device, see Rediscover Metric Families.
Rediscover a Device
To update a single monitored device, run rediscovery for that device.
You can also automate device rediscovery using REST.
For more information about this method of rediscovery, see Manage Discovery Profiles Using REST.
