Graphite has an amazing ability to scale horizontally and achieve high availability. What the community is missing is a single source for alerting and dashboards on top of this already amazing product. That's where Nark comes in. Nark is an open source project developed to provide alerting and dashboards for graphite. Developed by engineers at Lucid Software, Nark provides value to ops and product teams alike. Come learn about the project, how you can use it, and how to contribute.

4. GRAPHITE
• Graphite is a realtime, scalable analytics &
graphing tool
• Works well with StatsD
• Stores time series data
• Data organized by path name
stats.environment.servers.servername.path.to.metric
stats.environment.servers.servername.path.to.metric2
stats.environment.servers.servername2.path.to.metric

5. GRAPHITE
 Simple to store data
 Send variable name, value, and timestamp
stats.environment.servername.metricname 10 1399523324879
 Simple to retrieve data
 API to retrieve graphs & data
 http://graphite.readthedocs.org/en/latest/render_api.html
 98 complex functions
 Aggregate Functions (sumSeries, divideSeries, stacked, etc.)
 Filtering Functions (maxSeries, exclude, highestAverage, removeBelowValue, etc.)
 Transform Functions (abs, log, integral, derivative, etc.)
 Sorting Functions (sortByName, sortByMinima, etc.)
 See all at http ://graphite.readthedocs.org/en/latest/functions.html
 Demo

8. GRAPHITE -WHAT IT'S MISSING
 Dashboards
 Interactive graphs (static images aren't good enough)
 Variables in targets
 Sharing of dashboards
 Adaptability for different screen sizes
 Alerting
 Need reliable, highly-available alerting
 Tattle andCyren aren't good enough
