The Render URL API¶

The graphite webapp provides a /render endpoint for generating graphs and retreiving raw data. This endpoint accepts various arguments via query string parameters. These parameters are separated by an ampersand (&) and are supplied in the format:

&name=value

To verify that the api is running and able to generate images, open http://GRAPHITE_HOST:GRAPHITE_PORT/render in a browser. The api should return a simple 330x250 image with the text “No Data”.

Once the api is running and you’ve begun feeding data into carbon, use the parameters below to customize your graphs and pull out raw data. For example:

# single server load on large graph
http://graphite/render?target=server.web1.load&height=800&width=600

# average load across web machines over last 12 hours
http://graphite/render?target=averageSeries(server.web*.load)&from=-12hours

# number of registered users over past day as raw json data
http://graphite/render?target=app.numUsers&format=json

# rate of new signups per minute
http://graphite/render?target=summarize(deriviative(app.numUsers),"1min")&title=New_Users_Per_Minute

Note

Most of the functions and parameters are case sensitive. For example &linewidth=2 will fail silently. The correct parameter in this case is &lineWidth=2

Graphing Metrics¶

To begin graphing specific metrics, pass one or more target parameters and specify a time window for the graph via from / until.

target¶

This will draw one or more metrics

Example:

&target=company.server05.applicationInstance04.requestsHandled
(draws one metric)

Let’s say there are 4 identical application instances running on each server.

&target=company.server05.applicationInstance*.requestsHandled
(draws 4 metrics / lines)

Now let’s say you have 10 servers.

&target=company.server*.applicationInstance*.requestsHandled
(draws 40 metrics / lines)

You can also run any number of functions on the various metrics before graphing.

&target=averageSeries(company.server*.applicationInstance.requestsHandled)
(draws 1 aggregate line)

The target param can also be repeated to graph multiple related metrics.

&target=company.server1.loadAvg&target=company.server1.memUsage

Note

If more than 10 metrics are drawn the legend is no longer displayed. See the hideLegend parameter for details.

from / until¶

These are optional parameters that specify the relative or absolute time period to graph. from specifies the beginning, until specifies the end. If from is omitted, it defaults to 24 hours ago. If until is omitted, it defaults to the current time (now).

There are multiple formats for these functions:

&from=-RELATIVE_TIME
&from=ABSOLUTE_TIME

RELATIVE_TIME is a length of time since the current time. It is always preceded my a minus sign ( - ) and follow by a unit of time. Valid units of time:

Abbreviation	Unit
s	Seconds
min	Minutes
h	Hours
d	Days
w	Weeks
mon	30 Days (month)
y	365 Days (year)

ABSOLUTE_TIME is in the format HH:MM_YYMMDD, YYYYMMDD, MM/DD/YY, or any other at(1)-compatible time format.

Abbreviation	Meaning
HH	Hours, in 24h clock format. Times before 12PM must include leading zeroes.
MM	Minutes
YYYY	4 Digit Year.
MM	Numeric month representation with leading zero
DD	Day of month with leading zero

&from and &until can mix absolute and relative time if desired.

Examples:

&from=-8d&until=-7d
(shows same day last week)

&from=04:00_20110501&until=16:00_20110501
(shows 4AM-4PM on May 1st, 2011)

&from=20091201&until=20091231
(shows December 2009)

&from=noon+yesterday
(shows data since 12:00pm on the previous day)

&from=6pm+today
(shows data since 6:00pm on the same day)

&from=january+1
(shows data since the beginning of the current year)

&from=monday
(show data since the previous monday)

Data Display Formats¶

Along with rendering an image, the api can also generate SVG with embedded metadata or return the raw data in various formats for external graphing, analysis or monitoring.

format¶

Controls the format of data returned. Affects all &targets passed in the URL.

Examples:

&format=png
&format=raw
&format=csv
&format=json
&format=svg

png¶

Renders the graph as a PNG image of size determined by width and height

raw¶

Renders the data in a custom line-delimited format. Targets are output one per line and are of the format <target name>,<start timestamp>,<end timestamp>,<series step>|[data]*

entries,1311836008,1311836013,1|1.0,2.0,3.0,5.0,6.0

csv¶

Renders the data in a CSV format suitable for import into a spreadsheet or for processing in a script

entries,2011-07-28 01:53:29,2.0
entries,2011-07-28 01:53:30,3.0
entries,2011-07-28 01:53:31,5.0
entries,2011-07-28 01:53:32,6.0

json¶

Renders the data as a json object. The jsonp option can be used to wrap this data in a named call for cross-domain access

[{
  "target": "entries",
  "datapoints": [
    [1.0, 1311836008],
    [2.0, 1311836009],

    [5.0, 1311836011],
    [6.0, 1311836012]
  ]
}]

svg¶

Renders the graph as SVG markup of size determined by width and height. Metadata about the drawn graph is saved as an embedded script with the variable metadata being set to an object describing the graph

pie: A pie graph with each slice displaying an aggregate of each metric calculated using the function specified by pieMode

hideLegend¶

Default: <unset>

If set to true, the legend is not drawn. If set to false, the legend is drawn. If unset, the LEGEND_MAX_ITEMS settings in local_settings.py is used to determine whether or not to display the legend.

Hint: If set to false the &height parameter may need to be increased to accommodate the additional text.

Example:

&hideLegend=false

hideAxes¶

Default: False

If set to true the X and Y axes will not be rendered Example:

&hideAxes=true

hideYAxis¶

Default: False

If set to true the Y Axis will not be rendered

hideGrid¶

Default: False

If set to true the grid lines will not be rendered

Default: slope

Sets the line drawing behavior. Takes one of the following parameters:

slope: Slope line mode draws a line from each point to the next. Periods will Null values will not be drawn
staircase: Staircase draws a flat line for the duration of a time period and then a vertical line up or down to the next value
connected: Like a slope line, but values are always connected with a slope line, regardless of whether or not there are Null values between them

Example:

&lineMode=staircase

lineWidth¶

Default: 1.2

Takes any floating point or integer (negative numbers do not error but will cause no line to be drawn). Changes the width of the line in pixels.

Example:

&lineWidth=2

logBase¶

Default: <unset>

If set, draws the graph with a logarithmic scale of the specified base (e.g. 10 for common logarithm)

localOnly¶

Default: False

Set to prevent fetching from remote Graphite servers, only returning metrics which are accessible locally

majorGridLineColor¶

Default: value from the [default] template in graphTemplates.conf

Sets the color of the major grid lines.

minXStep¶

Default: 1

Sets the minimum pixel-step to use between datapoints drawn. Any value below this will trigger a point consolidation of the series at render time. The default value of 1 combined with the default lineWidth of 1.2 will cause a minimal amount of line overlap between close-together points. To disable render-time point consolidation entirely, set this to 0 though note that series with more points than there are pixels in the graph area (e.g. a few month’s worth of per-minute data) will look very ‘smooshed’ as there will be a good deal of line overlap. In response, one may use lineWidth to compensate for this.

Default: False

Set to disable caching of rendered images

pickle¶

Deprecated since version 0.9.10: See Data Display Formats

pieMode¶

Default: average

The type of aggregation to use to calculate slices of a pie when graphType=pie. One of:
