Experiencing a sudden increase in the CPU utilization of the TCPIP STC over multiple weekends in PROD system. Concerned about it might negatively affect overall CPU utilization. Nothing in the TCP/IP log. Looking for a way to analyze the TCPIP problem n NETMASTER (like what application used it, comparing TCPIPs previous datas, etc).
Release: SLOPFC00200-12.1-NetMaster Network Management for TCP/IP
Monitoring CPU is usually the domain of a SysView/Omegamon, but NetMaster can help in determining if things are out of the norm. Check performance data within the product (shortcut is /PERF). Baselining can be used to get a feel what is normal and what is not. Review Stack Network Interfaces, Stack IP Connections, Address Spaces, Stack IP, TCP, and UDP, potentially even CSM - if it is being monitored - to see if there are any outliers.
There are many drill down capabilities showing hourly, daily, and weekly information. For example, Stack IP Connections provides a simple number of Total connections. It would be easy to see if there's been an increase in total number of connections and go from there.
