Memcached memory usage

Question

Is there any command line or php script which returns the memcached total memory usage?

Answer 1

As Mike said, you can look at the line including the "STAT bytes" to see memory usage:

$ echo "stats" | nc -w 1 <host> <port> | awk '$2 == "bytes" { print $2" "$3 }'

Answer 2

memcache's default port is 11211 so if memcache is local

telnet localhost 11211

Then run the stats command and that will spit out memory usage

stats

Answer 3

I personally use PhpMemcacheAdmin

http://code.google.com/p/phpmemcacheadmin/

It creates an easy to use GUI. Of course you'll need to have PHP support.

Answer 4

Another alternative to answer @mike,

echo "stats" | nc localhost 11211
#or
echo "stats settings" | nc localhost 11211

Answer 5

If you are using php:

$m = new Memcached();
$m->addServer('localhost', 11211);
echo $m->getStats()['localhost:11211']['bytes'];
