+Memcached Multi - A Plugin to monitor Memcached Servers (Multigraph)

 
 

-[memcached_*]
- env.host 127.0.0.1     *default*
- env.port 11211         *default*
- env.timescale 3        *default*
+ The common difference between this memcached Munin plugin and others that exists, is that
+ others don't expose slab information from memcached, so you can better tune your memcached
+ interaction / stability / etc. With this plugin we leverage multigraph capabilities in
+ Munin to "hide" the slab information underneath of their parent graphs.

  port = port we are connecting to, in order to gather stats
  timescale = what time frame do we want to format our graphs too

+ cmds = cmd types to display on cmd graph, remove cmds you don't want displayed from list.
+ leitime = setting this to 1 will re-enable slab eviction time graphs, see note below.

 Please make sure you can telnet to your memcache servers and issue the
  following commands: stats, stats settings, stats items and stats slabs.

 =head1 ADDITIONAL INFORMATION
 
 
 =head1 ADDITIONAL INFORMATION
 

+B<NOTE:> The slab plugin for LEI has been disabled since I believe the counters to be inaccurate,
+    or perhaps not being updated as often I thought they would be. They can be re-enabled by
+    setting an environment variable, see munin configuration section at the top.
+

 You will find that some of the graphs have LEI on them. This was done in order to save room
 on space for text and stands for B<Last Evicted Item>.
