memcached-tool - stats and management tool for memcached
memcached-tool <host[:port] | /path/to/socket> [mode]
memcached-tool is a Perl script used to print statistics from a running memcached
instance. The first parameter specifies the address of the daemon either by a hostname,
optionally followed by the port number (the default is 11211), or a path to UNIX domain
socket. The second parameter specifies the mode in which the tool should run.
Print slab class statistics. This is the default mode if no mode is specified. The
printed columns are:
# Number of the slab class.
The amount of space each chunk uses. One item uses one chunk of the appro-
Age of the oldest item in the LRU.
Pages Total number of pages allocated to the slab class.
Count Number of items presently stored in this class. Expired items are not auto-
Full? Yes if there are no free chunks at the end of the last allocated page.
Number of times an item had to be evicted from the LRU before it expired.
Seconds since the last access for the most recent item evicted from this
OOM Number of times the underlying slab class was unable to store a new item.
stats Print general-purpose statistics of the daemon. Each line contains the name of the
statistic and its value.
dump Make a partial dump of the cache written in the add statements of the memcached
