NAME
memcached-tool – stats and management tool for memcached
SYNOPSIS
memcached-tool <host[:port] | /path/to/socket> [mode]
DESCRIPTION
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.
MODES
display- Print slab class statistics. This is the default mode if no mode is specified. The printed columns are:
-
#- Number of the slab class.
Item_Size- The amount of space each chunk uses. One item uses one chunk of the appropriate size.
Max_age- 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 automatically excluded.
Full?- Yes if there are no free chunks at the end of the last allocated page.
Evicted- Number of times an item had to be evicted from the LRU before it expired.
Evict_Time- Seconds since the last access for the most recent item evicted from this class.
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 protocol.
