How to override gatling.conf for graphite configuration? - maven

Question

I downloaded gatling as a maven dependency and now I'm looking for how to override the gatling.conf file to configure the connection between gatling and graphite.
So I created a gatling.conf file like that :
data {
writers = [console, file, graphite] # The list of DataWriters to which Gatling write simulation data (currently supported : console, file, graphite, jdbc)
reader = file # The DataReader used by the charting engine for reading simulation results
console {
light = false # When set to true, displays a light version without detailed request stats
}
file {
bufferSize = 8192 # FileDataWriter's internal data buffer size, in bytes
}
leak {
noActivityTimeout = 30 # Period, in seconds, for which Gatling may have no activity before considering a leak may be happening
}
graphite {
light = false # only send the all* stats
host = "mygraphite.host.com" # The host where the Carbon server is located
port = 1010 # The port to which the Carbon server listens to (2003 is default for plaintext, 2004 is default for pickle)
protocol = "tcp" # The protocol used to send data to Carbon (currently supported : "tcp", "udp")
rootPathPrefix = "gatling" # The common prefix of all metrics sent to Graphite
bufferSize = 8192 # GraphiteDataWriter's internal data buffer size, in bytes
writeInterval = 1 # GraphiteDataWriter's write interval, in seconds
}
}
Inside my src/main/resources/conf/gatling.conf
Here's my pom.xml :
<build>
<plugins>
<plugin>
<groupId>io.gatling</groupId>
<artifactId>gatling-maven-plugin</artifactId>
<version>${gatling-plugin.version}</version>
<executions>
<execution>
<phase>test</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<configFolder>src/main/resources/conf/</configFolder>
<!-- Default values -->
<!--<configFolder>src/test/resources</configFolder-->
<dataFolder>src/main/resources/data</dataFolder>
<resultsFolder>target/gatling/results</resultsFolder>
<!--<!–<requestBodiesFolder>src/test/resources/request-bodies</requestBodiesFolder>-->
<simulationsFolder>src/main/scala</simulationsFolder>
<simulationClass>my.awesomeCompany.scenarios.Scenarios</simulationClass>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
What I'm doing wrong, there's an other way to do that with a config file ? Or I'll have to override all the options with jvm args ?
Cheers.

You're missing the configuration root, gatling. Therefore, your values overrides nothing. Wrap your data { … } block in a gatling { … } block and it'll work.
