Quick description of tools used for performance and monitoring in conjunction with a FAS system..
- netstat lists open connections and statistics on them
- ifstat lists NIC's and statistics on them
- pkkt gathers data on the a single interface and the network traffic on that interface for analysis
- statit used to produce/analyze statistics on component performance
- stats low level perf data - network
- sysstat high level perf summary: cp's, cpu, protocols, etc.
- perfmon downloadable all-purpose performance tool. big gun.
- netmon essentially a lightweight version of wireshark.
- ethereal network analysis tool. Basic idea is it tries to grab all available packets and figure out what's going on.
