Hi,

Looks like your memcached service is not running (?) :

send() on unopened socket at...

Are you running memcached on the default port 11211 ?


Could you uncomment the last line of memcache.pl and
send back the ouptut of "bin/bbcmd ext/memcache.pl" ?

Hi, Oliver !

Thanks for the answer ...

i knew nothing about "memcached service",
and of course it didn't running  :-(

But after install,
everything is ok :-)

thanks for the nice script

cheers,

 Any idea, what's going wrong for me ?

 Hi All,

 I wrote a quick script to monitor memcached on a hobbitclient.
 (it needs perl's Cache::Memcached)

Hello all,

I'm using your script for some weeks now but no graph displays. I simply follow your directives (add a line in hobbitserver.cfg, add a graph definition into hobbitgraph.cfg) and as a result I have a simple line "hobbit graph ncv:mcache" with a magnifier near it. The rrd database is filling up and looks good :

Everything seems fine but no graph is showing up. Please help ! Thanks.
