Nginx – configuring munin-node for nginx

Did you restart munin-node after putting the memcached plugins in the plugin directory? Are any of them listed if you run 'list' when connected with telnet?

Any of the memcached plugins I've seen need the port and ip included in the name of the plugin, like the if_ scripts, where there's just symlinks into /etc/munin/plugins like:

# ls /etc/munin/plugins/memcached_bytes_127_0_0_1_11211 
lrwxrwxrwx 1 root root 39 2010-02-01 05:56 /etc/munin/plugins/memcached_bytes_127_0_0_1_11211 -> /usr/local/share/munin/memcached_bytes_

Finally I got it working. Munin is not that bad, all you need is to spend a couple of nights with it.

I misunderstood the documentation, you need not to mention hostname. Plugin name should be exactly same as on munin nodes. Also the same plugin should exist on Munin-master with __.

So, in /etc/munin/plugins now symblinks looks like:

postgres_checkpoints__ -> /usr/share/munin/plugins/postgres_checkpoints

And here is the new configuration, note the plugin-name after ":" doesn't have hostname in it:

postgres_checkpoints_total.update no  
pg_checkpoints.label Graph label  
postgres_checkpoints_total.graph yes  
postgres_checkpoints_total.graph_args --base 1000 -l 0  
postgres_checkpoints_total.cdef 0  
postgres_checkpoints_total.graph_category PG Total Checkpoints  
postgres_checkpoints_total.graph_title Aggregated checkpoints  
postgres_checkpoints_total.graph_vlabel Total Checkpoints  
postgres_checkpoints_total.checkpoints_req_total.label Total Req checkpoints  
postgres_checkpoints_total.checkpoints_timed_total.label Total Timed checkpoints  
postgres_checkpoints_total.graph_order checkpoints_req_total checkpoints_timed  
postgres_checkpoints_total.checkpoints_req_total.sum \  
        <internal_ip>.us-est-1.compute.internal:postgres_checkpoints.checkpoints_req \  
        <internal_ip>.us-west-1.compute.internal:postgres_checkpoints.checkpoints_req \  
        <internal_ip>.us-west-1.compute.internal:postgres_checkpoints.checkpoints_req

postgres_checkpoints_total.checkpoints_timed_total.sum \  
        <internal_ip>.us-west-.compute.internal:postgres_checkpoints.checkpoints_timed \  
        <internal_ip>.us-west-1.compute.internal:postgres_checkpoints.checkpoints_timed \  
        <internal_ip>.us-west-1.compute.internal:postgres_checkpoints.checkpoints_timed

Also, please note that now in the above configuration I am aggregating 2 functions.
