Metrics
The Metrics tab shows how your environment is performing: CPU, memory and HTTP request stats for the environment you're viewing.
CPU
The percentage of your plan's allocated CPU in use, averaged over five minutes. At 100% the environment is using its full CPU allotment.
Memory
The percentage of your environment's memory limit in use.
HTTP Requests
The total number of requests over the selected window, with a breakdown of 2xx, 4xx and 5xx responses and each one's share of the total. Amezmo measures this at the load balancer. There's no response-time metric here.
Time Ranges
CPU and Memory each have a time-range menu: 1 minute, 5 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, 24 hours and 1 week. Plans with 30-day retention also get a 30-day option. The default is the last 30 minutes, and your choice is remembered.
Alerts
From the CPU and Memory panels you can set an alert that emails you when usage crosses a threshold you choose.
