A template defines what kind of data a graph visualizes, which kind of graph to use and its style. Essentially this module is using templates to tell Graphite how to render which graphs.

Template Location

There are a bunch of templates already shipped with this module, located in its installation path. (e.g. /usr/share/icingaweb2/modules/graphite)

To add additional/customized templates, place them in its configuration path. (e.g. /etc/icingaweb2/modules/graphite/templates) These will either extend the available templates or override some of them. Subfolders placed here will also be included in the same way, while additionally extending or overriding templates of its parent folders.


Hidden files and directories (with a leading dot) are ignored by this module.

Template Structure

Templates are organized within simple INI files. However, it is perfectly valid to define multiple templates in a single file.

The name of a section consists of two parts separated by a dot:


The first part is the name of the template and the second part the name of one of the following configuration topics:


Supports a single option called check_command and should be set to the name of a Icinga 2 check-command.
To get multiple graphs for hosts and services with this check-command, multiple templates can reference the same check-command.

If multiple check commands do effectively the same thing and yield the same perfdata, all of them may be specified separated by comma. E.g.:

check_command = "ping, ping4, ping6"


Define what metric to use and how many curves to display in the resulting graph.
Each option’s key represents the name of a curve. Its value the path to the metric in Icinga 2’s graphite naming schema. If no metrics are given, no graphs are rendered.

Curve names are used to map Graphite functions to metrics. (More on this below) However, they are fully arbitrary and have no further meaning outside template configurations.

A curve’s metric path must begin with either the macro $host_name_template$ or $service_name_template$ and is substituted with Icinga 2’s prefix label. The rest of the path is arbitrary, but to get meaningful results use a valid path to one of the performance data metrics:


An example path which points to the metric value of the rta perfdata-label looks as follows:


To dynamically render a graph for each performance data label found, define a macro in place for the actual perfdata-label:



The name of the macro for the perfdata-label is also arbitrary. You may as well use a more descriptive name such as $disk$ for the disk check.


Allows to define additional URL parameters to be passed to Graphite’s render API.

Each option represents a single parameter’s name and value. A list of all supported parameters can be found here.

If you have used a macro for the curve’s perfdata-label you may utilize it here as well:

title = "Disk usage on $disk$"

You may also define URL parameters once for all templates (including the ones shipped with this module) in the default_url_params section in /etc/icingaweb2/modules/graphite/config.ini:

yUnitSystem = "none"

These may be overridden in the template itself:

yUnitSystem = "binary"


Allows to define Graphite functions which are applied to the metric of a specific curve on the graph.

Each option’s key must match a curve’s name in order to apply the function to the curve’s metric. A list of all supported functions can be found here.

The metric in question can be referenced in the function call using the macro $metric$ as shown in the following example:

alias(color(scale($metric$, 1000), '#1a7dd7'), 'Round trip time (ms)')

Template Example

The configuration examples used in this document are borrowed from the template for the hostalive check-command:

check_command = "hostalive"

rta.value = "$host_name_template$.perfdata.rta.value"

areaAlpha = "0.5"
areaMode = "all"
min = "0"
yUnitSystem = "none"

rta.value = "alias(color(scale($metric$, 1000), '#1a7dd7'), 'Round trip time (ms)')"

check_command = "hostalive"

pl.value = "$host_name_template$"

areaAlpha = "0.5"
areaMode = "all"
min = "0"
yUnitSystem = "none"

pl.value = "alias(color($metric$, '#1a7dd7'), 'Packet loss (%)')"
