Monitor Connections per IP

Overview

If a user wants to view the total connections for Applications and/or Internal/External IP's, then they can go to Monitor --> Service Levels --> TCP health (tab)

Resolution

The TCP Health report shows the number of total, aborted, refused, and ignored connections over time. The report can be viewed by applications, or internal or external hosts. You can drill into particular apps or hosts to view the health for particular traffic. This report can answers questions such as "Why are there so many retransmissions for a particular application or host?"

• AbortedÊÑ Connections were established, but were closed by a RST (reset) issued by either the client or server rather than a clean close. High numbers of aborted connections can point to network or server problems.

• RefusedÊÑ A SYN packet was observed and a RST or ICMP "connection refused" message was received in response. This usually means the server is up, but the application is unavailable or not working correctly. It can also indicate a TCP port scan is occurring.

• IgnoredÊÑ A SYN packet was observed, but no SYN-ACK response was received. This usually means the server is not responding, does not exist, is not accessible, or is ignoring the connection request. It can also indicate a TCP port scan is occurring.
