VPLEX monitor enable

Last updated: 2026-06-19

Might happen that not all default monitors we use providing perfomance data.
To check it and enable use this procedure (all below monitors for each director must be running):

Check monitor status under admin account:

VPlexcli:/> ll /monitoring/directors/*/monitors/                                                                                                                                                                                            
  /monitoring/directors/director-1-1-A/monitors: 
  Name                                                            Ownership  Collecting  Period  Average  Idle   Bucket  Bucket  Bucket  Bucket

  ...

Delete monitors which are not collecting data
- VPLEX:
```
VPlexcli:/> monitor destroy <monitor name>
```
- Metro Node:
  Dynamic monitor 'director-1-1-A_VIRTUAL_VOLUMES_PERPETUAL_MONITOR' is required by the EMC Diagnostics Team and for the performance monitoring charts in the GUI. Dynamic monitors cannot be destroyed.
  You have to place a SR to DELL/EMC to destroy it, you cannot correct them by yourself.
Restart CLI from server management (not from vplexcli):
```
sudo /etc/init.d/VPlexManagementConsole restart
```
Note: Dell has changed their startscript from "init.d"/"rc.d" to "systemd" (VPLEX software V6.2 [based on SLES 15.3]).
Login with the "service" user and used:
```
sudo systemctl restart VPlexManagementConsole
```
Afterwards you can check the status with (and "sudo" is not needed):
```
systemctl status VPlexManagementConsole
```
