Environment

VMware vRealize Operations 8.x

Cause

• Suite-API query length is longer due to inclusion of resource UUIDs in the query. 

Resolution

• Fix for this issue will be available in the next release of vCD Management Pack.

Workaround:

This issue has been addressed by increasing the HA proxy buff length in Cloud Proxies.

 

Please follow below steps to address the issue:

 

1. SSH to the affected Cloud Proxies and Modify /etc/haproxy/haproxy.cfg file and add 'tune.bufsize 65536' below "maxconn config" and perform a service restart (service haproxy stop and service haproxy start).
2. After making the required changes, HAproxy log reports "200 - OK" for API and not "400 - Error".

 

Note:- The config entry in HAconfig file doesn't persist once Cloud Proxy is upgraded, hence post upgrade same changes are required to be made again in Could Proxie(s).
