benchmark-clients

A Command line tool base on https://www.eclipse.org/leshan/ to simulate a fleet of LWM2M clients.

Get the last version of benchmark-clients-*.jar.

To launch it :

`java -jar benchmark-clients-*.jar -u coap://leshan.eclipseprojects.io`

(Please 🙏! Do not use this tool to kill(Dos) the leshan sandbox 😅)

Here is the command option :

Usage: leshan-clients-launcher [[-g] [--graphite-url=<serverAddress>]
                               [--graphite-polling-period=<pollingPeriodInSec>]]
                                [-bfhrV] [-c=<communicationPeriodInSeconds>]
                               [-d=<durationInSeconds>] [-e=<endpointPattern>]
                               [-i=<pskIdPattern>] [-k=<pskKeyPattern>]

  -e, --endpoint-pattern=<endpointPattern>
                          A String.format pattern used to create the client

  -i, --pskid-pattern=<pskIdPattern>

You can report stats on graphite.
Using the ugly default UI, this looks like this :

To build it :

mvn clean install

then run it :

java -jar target/benchmark-clients-*-SNAPSHOT-jar-with-dependencies.jar -u coap://leshan.eclipseprojects.io
