I have a munin-master and munin-node installed on same server (Ubuntu 9.10 server).
Most pre-installed plugins work well but the following plugins are with blank graph:
Memcached bytes used Memcached connections Memcached cache hits and misses Memcached cached items Memcached requests Memcached network traffic MySQL Queries Cache Size
I run the following 3 script in terminal and results were ok.
/etc/munin/plugins/memcached_bytes /etc/munin/plugins/memcached_counters /etc/munin/plugins/memcached_rates
But when I tried the command below after "telnet localhost 4949"
fetch memcached_bytes # Unknown service etch memcached_bytes_ # timeout pid 28009 - killing...done
Does anyone know the reason?
