nginx-munin

Munin plugin for Nginx.

With simple and straight specifications. I am not interested in instantaneous Requests/sec value measured by only 1 sec, but I am interested in average Requests/sec value from whole measuring period.

Graph Fields

• Requests/sec
• Accepted connections/sec
• Handled connections/sec
• Active connections
• Reading connections
• Writing connections
• Keep-Alive connections

Graph Types

1. default

• Only Requests/sec, Accepted connections/sec, Active connections and Keep-Alive connections values in one graph

2. request

• Only Requests/sec values in one graph

3. connection

• Only Active, Reading, Writing and Keep-Alive connections values in one graph

4. all

• All status values in one graph

Graph type is specified by tail of filename.
