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 con-
tains 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.
