#Gatling, InfluxDB and FatJars

Preparing the Project

There are a few things to remember when creating a Gatling FatJar:

• Use props.dataDirectory("jar") to enable loading of resources from the classpath
• There needs to be an empty class in src/test/scala because Gatling is doing a hardcoded check against the existence of target/test-classes when run from the IDE.

Building the FatJar

I use the maven-shade-plugin to create the FatJar. The version included in this project strips the META-INF-contents to avoid problems with signed JARs.

##Instructions to get InfluxDB running on Mac OS X brew install influxdb

After that open /usr/local/etc/influxdb.conf and check that the Graphite section looks like this:

[[graphite]]
   enabled = true
   bind-address = ":2003"
   database = "gatling"
   protocol = "tcp"

Fire up InfluxDB: influxd -config /usr/local/etc/influxdb.conf

Connect to it: influx

And then use the followoing command sequence:

• use gatling
• show series
• select * from "gatling.basicsimulation.request_1_Redirect_1.ok.percentiles99-0";
