Getting memcached Statistics

The memcached system has a built-in statistics system that collects information about the data being

stored into the cache, cache hit ratios, and detailed information on the memory usage and distribution

of information through the slab allocation used to storę indrvidual items. Statistics are provided at

both a basie level that provide the core statistics, and morę specific statistics for specific areas of the memcached server.

This information can be useful to ensure that you are getting the correct level of cache and memory

usage, and that your slab allocation and configuration properties are set at an optimal level.

The stats interface is available through the standard memcached protocol, so the reports can be

accessed by using telnet to connect to the memcached. The supplied

memcached-tool includes

support for obtaining the Section 15.6.4.2, “memcached Slabs Statistics” and Section 15.6.4.1,

“memcached General Statistics" information. For morę information, see Section 15.6.4.6, “Using

memcached-tool".

Alternatively, most of the language API interfaces provide a function for obtaining the statistics from the server.
