Abnormal amount of requestors - alerting?
We were performing an upgrade over the weekend where we had two different environments running. We did move some stream nodes over from the existing BAU environment to the upgrade environment. That went well.
Several hours later we had 5 servers with over 70k requestors (we didn't have 70k users).
I saw that there are PEGA0030 alerts however they're not part of the pdc event notifications. The agent that writes to STD out wasn't writing at the time.
Are there any other ways to detect a high requestor count per server?

@DPCLARK12are there any checks is node alive kind hitting the env for health monitoring ? i.e unauthenticated browser requestors coming ?
If so please config pega ping service in health monitoring end point url instead of prweb which will not create blank unauth requestors .
Have faced this before as well.

@Soham_Chanda1107 We don't have that today. I do want to move towards the ping service. We had it at the load balancer as a health check.

@DPCLARK12 its ootb so you dont need to worry thats what my guess was correct. http://<<hostName:port/contextName>>/PRRestService/monitor/pingservice/ping try this in you browser this will return you server stats. and sample response is
{ "node_id":"myCustomNodeId", "node_type":[ "WebUser", "Stream" ] , "health":[ { "test_name":"Streamservice-Check", "status":"success", "last_reported_time":"2018-07-30T20:37:29.656" },{ "test_name":"HTML-Stream-Check", "status":"success", "last_reported_time":"2018-07-30T20:37:29.656", } ], "status":"healthy" }
hopefully load balancer is F5 I guess.
