Issue/Introduction

  • When executing a VALIDATE CONNECTION action on an adapter instance in Aria Operations, it fails with the following error message: Could not find any up collector in the collector group.
  • You may receive an alert 'One or more vRealize Operations services on a cloud proxy are down' in Aria Operations.
  • All cloud proxies are showing as Offline in the Product UI.
  • The /var/log/haproxy-admin.log on the Cloud Proxy may show errors similar to:
    Server PrxyRC_BE/VROPS_0 is DOWN, reason: Layer6 invalid response, info: "SSL handshake failure", check duration: ###ms. 0 active and 0 backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue.
  • The following command entered via SSH on the cloud proxy identifies the certificate has expired: 
    openssl s_client -connect aria_operations_fqdn:443
     

Environment

Aria Operations 8.x

Cause

This issue occurs when Aria Operations SSL certificates get expired.

Resolution

To resolve this issue execute the following steps:

1. If you are using a custom certificate then you would need to generate a new certificate and then install it in Aria Operations. Here are the instructions for the same: Configure a Certificate For Use With VCF Operations
2. If generating another custom certificate is not feasible, reload the default web certificate in Aria Operations. Here are the instructions for the same: Reload the default certificate in Aria Operations
3. After new certificate has been applied/default certificate has been reloaded reboot the cloud proxies and they will return to Online state.
