We are using EC2 instances and are monitoring the server usage.
Right now the main metric we are looking at is idle CPU: Monitoring load on AWS EC2
However, I am also hoping to monitor "load" as measured by the
top command. We are running on large instances, so it appears to us as if we have 2 cores.
For fully owned servers, I usually set the trigger value to slightly higher than the number of cores (e.g. if 2 cores, trigger an alert if the load is over 2.5 for more than a minute). Is this still the right thing to do on EC2?
