libmemcached Command-Line Utilities

In addition to the main C library interface, libmemcached also includes a number of command-line

Utilities that can be useful when working with and debugging memcached applications.

Ali of the command-line tools accept a number of arguments, the most critical of which is servers,

which specifies the list of servers to connect to when returning information.

The main tools are:

•    memcat: Display the value for each ID given on the command linę:

shell> memcat --servers=localhost hwkey Hello world

•    memcp: Copy the contents of a file into the cache, using the file name as the key:

shell> echo "Hello World" > hwkey shell> memcp —3ervers=localhost hwkey shell> memcat --servers=localhost hwkey Hello world

•    memrm: Remove an item from the cache:

3hell> memcat --servers-localhost hwkey Hello world

shell> memrm —servers-localhost hwkey shell> memcat --3ervers=localhost hwkey

•    memslap: Test the load on one or morę memcached servers, simulating get/set and multiple Client

operations. For example, you can simulatethe load of 100 clients performing get operations:

shell> memslap --servers-localhost --concurrency-100 --flush —test-get memslap —servers-localhost --concurrency-100 --flush —test-get Threads connecting to servers 100 Took 13.571 seconds to read data

•    memf lush: Flush (empty) the contents of the memcached cache.
