memcache-top.pl

"top" for memcache - watch the traffic and other stats in real-time. Yoikes.

NOTES

If Getopt::Long is installed:
  • Specify instances w/ --instances (multiple times or comma separated)
  • Specify default port w/ --port (defaults to 11211)
  • Specify sleep time w/ --sleep (default 3)
  • Specify color output w/ --color (default) or --nocolor
  • Specify lifetime stats w/ --lifetime or --nolifetime (default) NOTE: lifetime stats break thresholds for evictions, bytes.
  • Specify read and write bytes w/ --bytes (default) or --nobytes
  • Specify get and set commands w/ --commands or --nocommands (default)
  • Specify cumulative numbers w/ --cumulative (don't use with lifetime)
  • Run a single time without clearing the screen, good for scripts and the like: --oneoff
If Getopt::Long is not installed:
  • Specify sleep time by typing a number after the command.

Specify instances in @default_instances. Specify thresholds by defining %threshold. Written against memcached v 1.2.3, but works fine w/ later versions.
