check_memcached will give a critical message if a partiular memcached host is inaccessible.
It will generate a warning (only) if the hit/miss ratio falls below a given threshold (default 2)
It will generate a warning (only) if the number of evictions exceeds a given limit (default 10)
Hit/miss and evictions are measured over a 30 minute interval, using a memcached object to store the earlier statistics.
Almost ALL other check_memcached plugins just quote the raw stats, which are measured from when the daemon was last started.
By distinction, this plugin measures the hit/miss ratio over a well-defined time-interval (by default the last 30 minutes)
The thresholds for the hit/miss ratio and eviction-rate may be specified on the command line.
The measurement time-interval may also be specified on the command line (this interval is also used for the performance data)
This plugin is written in C and also requires:
Flex: http://flex.sourceforge.net/
libmemcached: http://libmemcached.org/libMemcached.html
v1.3 added rate-based performance statistics for better pnp4nagios integration (-r option)
