graphite-spark

A sparkline for graphite data: ▄ ▄ ▆ ▇ ▄ ▄ ▃ ▃

When to use

Its 3am you have just ssh'd to a server and due to performance problems. The Load seems high, but you look after 2000 servers... Is this a normal load? You need to know what is ''high'' for this system?

A quick graphitespark -l and you can see a 24 hour history of the loadavg for this system.

You know now that is a normal loadavg and you can investigate something else.

Usage

usage: graphitespark [-h] [-f filesystem] [-l] [-c custom graphite path]

Display a sparkline of this or other servers

optional arguments:

-h, --help            show this help message and exit
-f filesystem, --filesystem filesystem
-l, --loadavg
-c custom graphite path, --custom custom graphite path

Installation

The argparse module is a required dependency. If not already installed:

% pip install argparse

To install graphite-spark system wide:

% git clone https://github.com/daniellawrence/graphite-spark.git
% cd graphite-spark
% python setup.py install

Then, just execute:

% /usr/bin/graphitespark

To run standalone without installation:

% git clone https://github.com/daniellawrence/graphite-spark.git
% cd graphite-spark
% PYTHONPATH=src bin/graphitespark

Example - Check Load average

Checking the load averages of the current system that you are logged into straight from the command line!

server 1 % graphitespark -l
-24hours@1h blocks
1min load avg.
█ ▅ ▆ ▄ ▄ ▆ ▆ ▄ ▃ ▃ ▃ ▂ ▃ ▃ ▂ ▃ ▃ ▃ ▃ ▃ ▄ ▅ ▃ ▃

5min load avg.

15min load avg.

Example - filesystem capacity

Checking the the filesystem capacity of a local filesystem on the current host, from the data in a remote graphite server.

server 1 % graphitespark -f /var/tmp
Filesystem capacity: /var
-24hours@1h blocks
█ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ █ 
Max: 11.0       Min: 11.0       First: 11.0     Last: 11.0

As you can see the script was able to work out the mount point of the filesystem so that the data was still found in the graphite system.

Example - custom graphs

Checking anything that you want from any system that you are logged into. As the data is in the remote graphite system.

server 1 % graphitespark -c 'systems.s.server2.loadavg.15min'
-24hours@1h blocks
