Missing items from VNA Viptela Inventory in DX NetOps Performance Management

Products

• CA Virtual Network Assurance
• DX NetOps

Issue/Introduction

Switches are missing from inventory - can't tell which domain is missing them. I installed VNA 20.2.10. I added 3 domains and configured 3 engines for them. But only one added any switches. I know there should be more. Is there a way to look through the inventory and tell which domains don't have any switches?

Only see items from one Viptela domain where there are three domains configured.

Missing Switches from Virtual Network Assurance (VNA) Inventory when integrated with Cisco Viptela.

Environment

All supported Virtual Network Assurance releases

Cause

OutOfMemory errors seen in the server.log and oc.log files. In the server.log we see this show up before everything starts failing.

Resolution

Reconfigure the VNA_MAX_MEM value in the VNA_HOME/wildfly/bin/standalone.conf file.

• In VNA_HOME/wildfly/bin/standalone.conf file, change VNA_MAX_MEM. By default it is 4gb.
• After making the change restart the Wildfly service using the commands:
  • Stop wildfly:
    • RH6.x: service wildfly stop
    • RH7.x: systemctl stop wildfly
  • Start wildfly:
    • RH6.x: service wildfly start
    • RH7.x: systemctl start wildfly

The memory issues should be resolved and the complete Inventory should now be seen.
