NCDA Notes: Perf Tools

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.
