New Relic - Cloud Server Monitoring for SaaS

New Relic Cloud server monitoring lets you:

  • Monitor CPU usage, physical memory, network activity, load averages, and more as part of your APM tool
  • View all apps running on a server, and assess the impact of server utilization on web app performance
  • See which servers have capacity issues so you can take corrective action
  • See processes prioritized by memory or CPU consumption
  • Track server health availability in clouds, physical, or hybrid environments

New Relic’s Four Key Server Monitoring Metrics

When a user is trying to answer the first question, they need to quickly determine the status of many servers at once. The Servers Dashboard page shows a list of every server currently reporting, along with the four key server metrics, and a graphical “traffic light” that tells you at a glance what the overall health of the server is.

For an application, the key metrics are response time, throughput, and error rate. For servers, we needed to identify a set of similar key metrics, which can be used to immediately tell the overall health of a server. We chose CPU Busy, Disk Busy, Memory Used, and Disk Space Used. All four are shown as a percentage, where higher numbers are bad. This makes them easy and quick to compare across different servers.

CPU Busy and Disk Busy measure the percentage of the time that your system is using the CPU or performing Disk IO. As these numbers climb, processes will have a harder and harder time getting resources. This means that applications on this server will start to slow down. If the Disk or CPU becomes completely busy, it is very likely that those applications will become unresponsive.

By contrast, Memory Used and Disk Space Used won’t affect performance much until they start to run out, but when they do run out the consequences are severe. A climbing Memory number can cause other processes to be “swapped” out, which will have a devastating effect on performance. A server will run smoothly as disks fill up, but if the disks become completely full then you may experience many seemingly unrelated problems, especially if this server hosts a database.

Digging Deeper

Once a problem has been detected, it is time to dig deeper. If Disk IO is high, which disk is the one having trouble? If the CPU is busy, what is it busy doing? The starting point for any of these questions should be the Overview page for the server in question.
