Replication Latency Monitoring Job Automation

           I got a task to automate replication monitoring in my environment. So I created a procedure and called it from a job every 5 mins.

If there is latency ,This Procedure sent mail to dba team with latency details , job , and where exactly latency exists.

Create Procedure Replication_Latency_Monitoring ( @minutes int)
