Monitoring the AWS EC2 Cloud

Figure 1 depicts the AWS EC2 Cloud monitoring model that eG Enterprise offers out-of-the-box for monitoring the Amazon EC2 cloud.

Figure 1 : Layer model of the AWS EC2 Cloud

Each layer of this model is mapped to tests that reveal the availability of the cloud and whether the regions/availability zones/instances on the cloud are accessible. Using these statistics, cloud administrators can find quick and accurate answers for the following critical performance queries:

  • Is web-based (HTTP/HTTPS) access to the cloud available?
  • Does it take an unreasonably long time to establish contact with the cloud?
  • How many regions does the cloud support? What are they?
  • Is any region unavailable?
  • Were any connectivity issues experienced while attempting to connect to a region? If so, which region is this?
  • How many availability zones exist in each region? What are they?
  • Is any availability zone currently unavailable? If so, which one is it?
  • Is the default region on the cloud accessible? If so, is it taking too long to connect to the default region?
  • Are all instances on the cloud accessible over the network?
  • Are any instances powered off currently?
  • Were any instances launched/removed recently? If so, which ones are these?
  • What type of instances are resource-intensive?
  • Is any particular instance consuming too much CPU?
  • Is the network traffic to/from any instance unusually high?
  • Is the disk I/O of instances optimal?
  • Was any instance rebooted recently? If so, which one is it?

 

Note:

The eG agent reports metrics for only those regions, availability zones, and instances on the cloud that the configured AWS user account is allowed to access.

The sections that will follow discuss each of the layers of Figure 1 in great detail.
