The main panel in Grafana is simply named Graph. It provides a very rich set of graphing options.
Clicking the title for a panel exposes a menu. The
edit option opens additional configuration options for the panel.
The general tab allows customization of a panel’s appearance and menu options.
Title- The panel title on the dashboard
Span- The panel width in columns
Height- The panel contents height in pixels
Drilldown / detail link
The drilldown section allows adding dynamic links to the panel that can link to other dashboards or URLs
Each link has a title, a type and params. A link can be either a
absolute links. If it is a dashboard links, the
dashboard value must be the name of a dashboard. If it’s an
absolute link, the URL is the URL to link.
params allows adding additional URL params to the links. The format is the
name=value with multiple params separate by
&. Template variables can be added as values using
When linking to another dashboard that uses template variables, you can use
var-myvar=value to populate the template variable to a desired value from the link.
The metrics tab defines what series data and sources to render. Each datasource provides different options.
Axes & Grid
The Axes & Grid tab controls the display of axes, grids and legend.
Left Y and
Right Y can be customized using:
Unit- The display unit for the Y value
Grid Max- The maximum Y value. (default auto)
Grid Min- The minimum Y value. (default auto)
Label- The Y axis label (default “”)
Axes can also be hidden by unchecking the appropriate box from
The legend hand be hidden by checking the
Show checkbox. If it’s shown, it can be displayed as a table of values by checking the
Table checkbox. Series with no values can be hidden from the legend using the
Hide empty checkbox.
Additional values can be shown along-side the legend names:
Total- Sum of all values returned from metric query
Current- Last value returned from the metric query
Min- Minimum of all values returned from metric query
Max- Maximum of all values returned from the metric query
Avg- Average of all values returned from metric query
Decimals- Controls how many decimals are displayed for legend values (and graph hover tooltips)
The legend values are calculated client side by Grafana and depend on what type of aggregation or point consolidation you metric query is using. All the above legend values cannot be correct at the same time. For example if you plot a rate like requests/second, this is probably using average as aggregator, then the Total in the legend will not represent the total number of requests. It is just the sum of all data points received by Grafana.
Display styles controls properties of the graph.
Thresholds allow you to add arbitrary lines or sections to the graph to make it easier to see when the graph crosses a particular threshold.
Bar- Display values as a bar chart
Lines- Display values as a line graph
Points- Display points for values
Line Fill- Amount of color fill for a series. 0 is none.
Line Width- The width of the line for a series.
Null point mode- How null values are displayed
Staircase line- Draws adjacent points as staircase
If there are multiple series, they can be display as a group.
Stack- Each series is stacked on top of another
Percent- Each series is draw as a percent of the total of all series
If you have stack enabled you can select what the mouse hover feature should show.
- Cumulative - Sum of series below plus the series you hover over
- Individual - Just the value for the series you hover over
Flot- Render the graphs in the browser using Flot (default)
Graphite PNG- Render the graph on the server using graphite’s render API.
All series- Show all series on the same tooltip and a x crosshairs to help follow all series
Series specific overrides
The section allows a series to be render different from the rest. For example, one series can be given a thicker line width to make it standout.
