A simple Graphite dashboard built using Twitter's Bootstrap.
Adding new dashboards is very easy and individual graphs are described using a small DSL.
See the sample directory for a sample dashboard configuration.
This dashboard is a Sinatra application, I suggest deploying it in Passenger or other Sinatra application server.
A sample gdash.yaml-sample is included, you should rename it to gdash.yaml and adjust the url to your Graphite etc in there.
The SinatraApp class take two required arguments:
* Where graphite is installed * The directory that has your _dashboards_ directory full of templates
and additional options:
* The title to show at the top of your Graphite * A prefix to prepend to all URLs in the dashboard * How many columns of graphs to create, 2 by default. * How often dashboard page is refreshed, 60 sec by default. * The width of the graphs, 500 by default * The height of the graphs, 250 by default * Where your whisper files are stored - future use * Optional interval quick filters
You can have multiple top level categories of dashboard. Just create directories in the templatedir for each top level category.
In each top level category create a sub directory with a short name for each new dashboard.
You need a file called dash.yaml for each dashboard, here is a sample:
:name: Email Metrics :description: Hourly metrics for the email system
Then create descriptions in files like cpu.graph in the same directory, here is a sample:
title "Combined CPU Usage" vtitle "percent" area :stacked description "The combined CPU usage for all Exim Anti Spam servers" field :iowait, :scale => 0.001, :color => "red", :alias => "IO Wait", :data => "sumSeries(derivative(mw*munin.cpu.iowait))" field :system, :scale => 0.001, :color => "orange", :alias => "System", :data => "sumSeries(derivative(mw*.munin.cpu.system))" field :user, :scale => 0.001, :color => "yellow", :alias => "User", :data => "sumSeries(derivative(mw*.munin.cpu.user))"
The dashboard will use the description field to show popup information bubbles when someone hovers over a graph with their mouse for 2 seconds.
The graphs are described using a DSL that has its own project and documented over at https://github.com/ripienaar/graphite-graph-dsl/wiki
At the moment we do not support the Related Items feature of the DSL.
Template Directory Layout?
The directory layout is such that you can have many groupins of dashboards each with many dashboards underneath it, an example layout of your templates dir would be:
graph_templates `-- virtualization |-- dom0 | |-- dash.yaml | |-- iowait.graph | |-- load.graph | |-- system.graph | |-- threads.graph | `-- user.graph `-- kvm1 |-- dash.yaml |-- disk_read.graph |-- disk_write.graph |-- ssd_read.graph `-- ssd_write.graph
Here we have a group of dashboards called 'virtualization' with 2 dashboards inside it each with numerous graphs.
You can create as many groups as you want each with many dashboards inside.
Custom Time Intervals?
You can reuse your dashboards and adjust the time interval by using the following url structure:
This will display the email dashboard with a time interval same day last week. If you hit /dashboard/email/time/ it will default to the past hour (-1hour) See http://graphite.readthedocs.org/en/1.0/url-api.html#from-until for more info acceptable from and until values.
Quick interval filters shown in interface are configurable in gdash.yaml options sections. Eg:
:options: :interval_filters: - :label: Last Hour :from: -1h :to: now - :label: Last Day :from: -1day - :label: Current Week :from: monday :to: now
Quick filter is not shown when interval_filters section is missing in configuration file.
Time Intervals Display?
If you configure time intervals in the config file you can click on any graph in the main dashboard view and get a view with different time intervals of the same graph
:options: :intervals: - [ "-1hour", "1 hour" ] - [ "-2hour", "2 hour" ] - [ "-1day", "1 day" ] - [ "-1month", "1 month" ] - [ "-1year", "1 year" ]
With this in place in the config.yaml clicking on a graph will show the 5 intervals defined above of that graph
Full Screen Displays?
You can reuse your dashboards for big displays against a wall in your NOC or office by using the following url structure:
This will display the email dashboard in 4 columns each graph with a width of 600 and a height of 300
The screen will refresh every minute
