Gearman Plugin for Server Density

Gets information about a gearman queue. Requires Python 2.6 because of socket.create_connection, bytearray and probably a few other bits and pieces.

Example Configuration

You must specify the gearman_server config parameter in your sd-agent.conf (probably /etc/sd-agent/sd-agent.conf). If you don't, the plugin won't do anything (so that you can disable the plugin via config).

The port and timeout should be fine by default, and you don't need to specify them.

gearman_server:  localhost
#gearman_port:    4730
#gearman_timeout: 5

Output Keys

The plugin returns a bunch of output keys:

• gearman_%FUNCTION_NAME%_workers - The total number of workers capable of running that function
• gearman_%FUNCTION_NAME%_running - The number of this job currently being run by workers
• gearman_%FUNCTION_NAME%_queue - The number of this job on the queue
• gearman_total_workers, gearman_total_running, gearman_total_queue: as above, but totals across all functions.

Unfortunately, because the names vary, these are rather hard to set up in seperate Server Density graphs. You might be better off using a single graph and just toggling them on and off.
