How To Monitor PHP-FPM and Nginx With Zabbix

Distributed JMeter Testing Via SSH

JMeter is an open source application written in Java, developed by the folks from The Apache Software Foundation, which allows one to perform load tests against their webservers.
JMeter allows you to run tests from you workstation against your servers, but you can also setup virtual test servers that would allow you to run a heavier load.
If you run JMeter from your machine, you’ll probably end up consuming tons of cpu and memory, depending on how large your tests are, so, to avoid that, you can seetup your workstation as a JMeter MASTER and any number of virtual machines as JMeter SLAVES, which you will be able to control from your workstation. This setup is called Distributed JMeter Testing and that is what I’ll walk you through in this tutorial.
