VMware Aria Operations for Networks platform is not receiving data from one or more collectors

Products

• VCF Operations for Networks

Issue/Introduction

In the Setting > Infrastructure and Updates page, 3 out of 6 collectors display the error message "No data being received".

Additional errors are seen in the platform for the collector, for example in one we see multiple errors, for example:

1. Platform Health: Collector Lag
   Last data collection on collector was more than 30 minutes ago.
2. Platform Health: SNMP connection error
   SNMP connect error Alert type: Problem Severity: Critical Manager: CISCON9K_###.##.##.### 
3. Platform Health: Invalid credentials
   Invalid credentials

The collectors in question were unreachable via SSH, although previously this had worked fine.

When using the Web Console from vCenter to log into the collectors in question we found:

• Collector reports an NTP error
• Ping to the platform node 1 resulted in "Destination Host Unreachable" error.

 

Environment

VMware Aria Operations for Networks 6.10
VMware Aria Operations for Networks 6.11
VMware Aria Operations for Networks 6.12
VMware Aria Operations for Networks 6.12.1
VMware Aria Operations for Networks 6.13
VMware Aria Operations for Networks 6.14

Cause

These errors all point to an environment network issue with the collector. The collector has essentially been isolated on the network and cannot reach to/from the platform node.

Resolution

Identify the network issue that is resulting in loss of connectivity: this could be firewall rules, a gateway issue, or other issue on the network which does not allow communication between the platform nodes and the collector nodes.

If your deployment has encountered the issues as per errors in above screenshot and you need assistance identifying the Issue , contact Broadcom support by opening support Case to triage it further.
