Metron throughput tests

Code in src/github.com/jriguera/metron-throughput.

Note: because router (doppler) app defines its libraries with path /internal, golang does not allow to import them in a different project, so we have decided to manually copy the libs in src/github.com/jriguera/metron-throughput/receiver/internal.

Once this release is deployed, you have to run the script /var/vcap/jobs/metron-test-receiver/bin/run on the receiver, which is a fake doppler router. This script runs the binary in a (infinite) loop, the program automatically exits after 30 seconds of the latest sucessfully received log (fiter by Origin) It will keep listening forever if it does not receive logs with the proper origin.

The sender runs next to metron_agent, it will generate a lot of logs by running it with /var/vcap/jobs/metron-test-logger/bin/run (see run -h for extra options).

With the output of both commands you can see the performance of metron_agent.

You can use nohup to run the launchers (they accept args!):

• sender: /var/vcap/jobs/metron-test-logger/bin/run (one shot script, but you can create a loop, make sure to wait more than 30s between loops)

rm /var/vcap/sys/log/metron-test-logger/metron-logger.log; 
for i in $(seq 1 10);
do
    /var/vcap/jobs/metron-test-logger/bin/run;
    sleep 60;
done

• receiver: /var/vcap/jobs/metron-test-receiver/bin/run (keeps metron-receiver running)

These scripts log the results to:

• sender: /var/vcap/sys/log/metron-test-logger/metron-logger.log
• receiver: /var/vcap/sys/log/metron-test-receiver/metron-receiver.log

In order to analyze the log files, see the script generate_stats.sh included in the package to generate CSV from those logs. MAKE SURE BOTH LOG FILES ARE DELETED BEFORE STARTING A STATS COLLECTION otherwise the lines will not match between the sender and the receiver.
