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. 

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

2. Create the NSRVIM_TIME_INTERVAL on the NetWorker server. Adding or changing this variable requires a nsrd 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
