NVP vProxy: NetWorker nsrvim process runs every 15 minutes causing a high workload on vCenter Server and potential VPXD unavailability

• The NetWorker server has been configured for VMware protection of a vCenter server.
• The vCenter server observes issues with the VMware Virtual Provisioning X Daemon (VPXD) service availability or general high workload.

NetWorker's vCenter inventory process (nsrvim) is initiated during service startup then runs every 15 minutes (default). This process also runs anytime a VMware protection job runs against the vCenter. Depending on how many NetWorker servers are connected to the vCenter, and the amount or frequency of VMware protection policy operations. This causes several inventory query requests against the vCenter server in a short window.
This task is observed in the daemon.log on the NetWorker server as:

The same messaging appears when a VMware protection policy runs. 

Create the NSRVIM_TIME_INTERVAL environment variable on the NetWorker server to adjust the nsrvim schedule. Adding or changing this variable requires a NetWorker Server (nsrd) daemon restart. To create the environment variable, perform the following depending on the operating system of the NetWorker server:

sudo vi /nsr/nsrrc

NSRVIM_TIME_INTERVAL=60
export NSRVIM_TIME_INTERVAL

sudo systemctl restart networker

1. Open an Administrator PowerShell prompt.
2. Run the following command

setx /m NSRVIM_TIME_INTERVAL 60

3. From a new PowerShell prompt, run:

echo $env:NSRVIM_TIME_INTERVAL

This should return the value set in step 2.

4. Reboot the server.

Windows User Interface

1. Open Control Panel, then click System and Security, then click System.
2. Click Advanced System Settings.

3. From System Properties, click Environment Variables.
4. Under System Variables, click New:

5. In the Variable Name field, enter: NSRVIM_TIME_INTERVAL
6. In the Variable Value field, enter a number from 15 to 60 (this number corresponds to minutes).
