Issue/Introduction

Need to know the core probes required to be deployed and running on UIM v9.02 post-upgrade. What probes can be deactivated or deleted from the Primary hub?

Cause

- optimize resource usage on the Primary hub server

Environment

Release : 9.0.2

Component : UIM - INSTALL

Resolution

In general on a Primary hub, here is a list of non-core probes that you may choose to deactivate, e.g., if you're not using the features of a given probe or the probe has been deprecated and is no longer used post upgrade.
 
Normally, the primary should be dedicated to core functions, as opposed to monitoring/remote monitoring tasks, so other than some local monitoring of the Primary and its resources, remote probes should NOT be deployed and running unless you must do it from the primary for some valid reason, e.g., the hub's location on the network that allows you to reach the given target(s). Remote monitoring probes should be deployed and operate from a Secondary/remote hub.

- baseline and prediction should be running on remote hubs, not the primary unless one of the probes deployed there has baselines enabled.
- ace (note that ace is no longer needed/used as of UIM v9.0.2)
- audit (optional)
- assetmgmt (deprecated)
- cm_data_import (optional)
- discovery_agent (can be offloaded to another hub)
- discovery_server (can be offloaded to a child robot connected to the Primary Hub especially IF the probe_discovery queue is frequently backing up and requires a significant increase in memory and you're close to the local machine's limit already)
- fault_correlation (optional)
- qos_processor (optional unless needed for frequent origin changes)
- relationship_services (optional)
- remote monitoring probes such as net_connect, rsp, etc.
- telemetry (optional)
- topology_agent (optional)

You can choose to deactivate one or more of the probes listed above, or do the following to delete them from the Primary hub, but if you need to save the probe's configuration/files for any reason first take a backup of the probe directory and save it off in a folder.

   - Deactivate the probe
   - Using IM, Rt-Click and delete the probe
   - Delete the probe directory from the file system
   - Ensure that the probe is gone within IM
