Could you tell me whether it is possible to show the number of concurrent connections(TCP) of specific software service in DCRUM? If yes, how can we do that?
Our customer has a restriction rule for concurrent connections.
They want to monitor the number of connections.
And they also want to know what software service use the connections.
There is no easy, direct way to measure number of concurrently open TCP connections to a server. Such statistics would have to be tracked continuously and reported as min, max and average per monitoring interval and further hour, day etc. DC RUM doesn't do it.
What we can measure are connection attempts, connection errors and idle sessions (open, but with no active traffic). This could help in finding and counting user connectivity errors because server refuses a connection, while other connections are open and idling. I understand this is not exactly what you are after, but nevertheless it may be helpful.
