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.
NetWorker 19.10 has introduced a new feature which allows the NetWorker backup administrator to tune the nsrvim frequency. This functionality was introduced by using a new environment variable on the NetWorker server. To use this environment variable, perform the following:
1. Upgrade the NetWorker server to 19.10.0.0 (or later). https://www.dell.com/support/home/product-support/product/networker/drivers
sudo vi /nsr/nsrrc
2. Add the following lines to the file:
NSRVIM_TIME_INTERVAL=60
export NSRVIM_TIME_INTERVAL
3. Restart the NetWorker server services:
sudo systemctl restart networker
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).
