Using graphs

Graphs are divided into two sections. The upper section is for viewing data in close detail while the lower section displays a more broad, wide-ranged view. Inside the graph, metrics are displayed as color coded lines.

The lower portion of the graph has a slider which can be used to quickly track forward and backward as well as zoom in and out.

Displayed at the top of the page are the time span control buttons. Using these controls you can change the time interval graphs will display.

By mousing over any point on a graphed line, you can see detailed information about a metric at any particular moment.

Simplified Display

Any role graph from the Services detail screen with a large number of hosts (30 or more) is simplified. Stacked graphs display the sum and line graphs display the maximum, minimum, and average. By clicking “show all hosts” located at the bottom of the graph, a detailed version of the simplified graph can be seen.

In the opened up graph detail screen, graphs with more than 200 hosts are always simplified, but can be switched from the “simplify graph” checkbox.

Creating graph annotations

You can write notes on graphs about various events such as deploy, release, and batch timing. Create an graph annotation by dragging over the time section of the graph and inputting a title and description.

Posting graphs to notification channels

Graph URLs can be posted to notification channels directly from Mackerel. From the graph menu, click the camera icon, select a channel to send the graph URL to, and then press “Post”. By doing this, the URL will be posted collectively with the graph information.

Each notification channel can be configured from the Channel Settings.

This feature is not yet supported for alert graphs, embedded graphs in Dashboards etc., and preview graphs of expression monitoring. The notification channels that are currently supported are Slack, Hipchat, and Typetalk.
