Thanks. That is helpful. I did modify a script I found on the horde site that cleans the lock files made by horde.
Using the session id as a key you can tell if the session is still available in the memcached server. If you consider
each session id to be a user then you can get an approximate count of the number of valid sessions in the memcached
server and the total number of sessions (users) in a given period of time. I only clean the lock files once per day so
it would be a 24 hour period. Below is a copy of the modified script.
<?php
# Connect to memcache
$memcache = new Memcache;
$memcache->connect('yourmemcacheserver', 11211);
# Walk through lock files
$dir = "/dir/containing/lock/files";
$total = 0;
$removed = 0;
$dh = opendir($dir) or die("Unable to open '$dir'");
while(($filename = readdir($dh)) !== false) {
if (preg_match('/^lock_([a-z0-9]+)$/', $filename, $matches)) {
$key = $matches[1];
$total++;
if ($memcache->get($key) === false) {
$removed++;
}
}
}
closedir($dh);
$memcache->close();
echo "Number of daily users = $total\n";
$current = $total-$removed;
echo "Number of current users = $current\n";
?>

I was wondering if anyone out there has a php script I could use to
get data from the memcached server?
What I'm looking for us total number concurrent users, and if possible
number of stale sessions.
Thanks for your consideration.
memcached has no concept of users. However, the memcached website links
to this PHP-based control panel developed by someone:

No idea if it works.
