1. First of all check out that your server is not overloaded via Amazon CloudWatch <https://aws.amazon.com/cloudwatch/> or JMeter PerfMon Plugin <https://jmeter-plugins.org/wiki/PerfMon/> 2. IP Spoofing on Linux works the same way as on any other operating system, you just need to have all "virtual" IP addresses bond to one or multiple network interfaces, you can use something like:
> ifconfig eth0:0 10.20.30.40 up Replace "eth0" with your network interface name and "10.20.30.40" with the IP address of your choice. Repeat the command as many time as needed to create as many IP addresses aliases as required for your test scenario. See Using IP Spoofing to Simulate Requests from Different IP Addresses with JMeter <https://www.blazemeter.com/blog/using-ip-spoofing-simulate-requests-different-ip-addresses-jmeter> 3. Just in case add a DNS Cache Manager <http://jmeter.apache.org/usermanual/component_reference.html#DNS_Cache_Manager> to your Test Plan, if you have more than one Nginx instance behind the ELB <https://aws.amazon.com/elasticloadbalancing/> it might be the case JMeter hits only single instance while others are idle. -- Sent from: http://www.jmeter-archive.org/JMeter-User-f512775.html --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
