CA App Synthetic Monitor DX Application Performance Management

Issue/Introduction

Restarted an OPMS server to perform some OS updates and some checks are failing:

(-95) Checkpoint did not return status, full response: 'Checkpoint Error: 503 Service Unavailable. Database connection error: Error 2 connecting to unix socket: /var/run/redis/redis.sock. No such file or directory.'

 

 

Cause

Per Engineering, the "503 Service Unavailable: database connection" error is most likely caused by the services dependent on Redis getting started before Redis itself finished starting 
or  the UNIX Socket service may not running.  

Environment

Release : 10.1

Component : CA APP SYNTHETIC MONITOR (WATCHMOUSE)

Resolution

Starting the UNIX socket Service which was set to "manual start" solved the issue.
