Issue/Introduction

No data for ACIPolicy CAM data after verifying data was available via direct rest and OC ACQUISITION debug logging in Virtual Network Assurance

In the vna.log file on the Data Collector associated with the VNA gateway we see errors such as:

INFO  | sdn-performance  | YYYY-MM-DD HH:MM:SS,### | SDNPerformance | dn.performance.impl.SDNCollector  238 | processPollGroupMetrics: | Unable to find item ID for SDN ID 123 of MF CAM

Environment

Release : 20.2

Component : Virtual Network Assurance For CA Performance Management

Resolution

1) Try admin down/up VNA gateway to reconcile any changes.

2) If still an issue:

a) Stop/start polling for an example device provided data.

b) If that works to show the data,  try re-evaluating the SDN poll config for another device:=, from the Data Aggregator:

curl -v -X POST http://127.0.0.1:8581/action/polling-configuration/SDN/reevaluate/ITEMID

c) If b) works, that worked for that device, proceed to re-evaluate the polling config for all SDN devices:

curl -v -X POST http://127.0.0.1:8581/action/polling-configuration/SDN/reevaluate
