I love valuable metric data and I wanted to see what’s offered from different cloud providers. Metrics are data and data ensures that when performance is impacted, we have the information we need to answer questions and resolve issues.
For my first adventure, we’ll start with a high level review of Amazon. Cloudwatch is one of the main tools to inspect the workload on instances in EC2, using the AWS Trial while Swingbench runs the Sales History workload.
There is additional charges for this feature, but it’s pretty minimal per instance vs. other tools, so I’ll talk about the basics here and you can make up your own mind.
Once you enter this console, the graph area will be empty and you’ll need to add metrics to the graph. Since I’m using EC2, I click on EC2 in the Metrics area below the empty graph and each of the metrics available for each of my instances will be shown in a list.
Click on the instance and metric you’re interested and then a list of options will show. Click on Add to graph to add it to the graph above the list and have it start collecting metric data.
You can also click on the check box at the top of All Metrics to add them all.
Once you’ve completed adding the metrics for all the instances you’re interested in, you’re graph will look something like this:
As you can see, you can highlight the line on the graph to match it to the metric/instance name below the graph or vice-versa.
As most of the work for Swingbench is going to the source and then to the Delphix Engine to track the changes to be used by the targets, those first two instances and network activity will be the highest usage. I haven’t played with the Graphed Options tab, yet and will leave that for another day.
If there’s a metric for an instance you’ve added that isn’t providing any value to the charge, it’s simplest to click on the Graphed Metrics tab, then click on the checkmark in the list and it will stop displaying it in the graph.
If you haven’t had an opportunity to play with the free AWS Trial of Delphix, check it out! It’s a great way to become familiar with Delphix and AWS- all in one shot!
