Super Simple Server Stats Using Python and RRDTool

Collection of simple monitoring sccripts in Python. Why Python? Because. Demo at http://cybojanek.net:8080

Requirements

1. simplejson, rrdtool, twisted Python packages
2. web server

Installation

1. Configure config.json
2. Launch with twistd:

twistd -y server.py

Configuration

Why a JSON file? So I can reuse the info in index.html.

The configuration file is a single JSON dictionary, with the following usage:

• network_devices

  • dictionary of device name to role, ie: "eth0": "web"

• cpu

  • physical: number of physical cpus, used to mark max line, especially usefull for hyperthreading

• hdd

  • dictionary of device name to role, ie: "sda": "root"

• swap

  • Set to "true" / "false" for whether to record swap usage

• nginx

  • Set to a non empty url that points to the nginx stat module
  • You also need to enable the nginx stats module:

location /nginx_status {
    stub_status on;
    access_log   off;
}

ssssuprrd's Issues

Migration support for rrd sources

Have the ability to migrate previous rrd sources to be up to date with current standards for this project (ie new sources, changed names etc)

cpu graph whitespace

rsync caused cpu usage, but also a white gap, meaning reading /proc/stat was done incorrectly
