You will need to be able to set up our CloudFormation template in your AWS account. Head to our documentation which will walk you through the setup process.

Unlike other monitoring tools, the majority of functionmetric is self-hosted. We don't limit or charge based on the number of invocations you want to collect metrics for.

Data is collected directly from your Cloudwatch logs in real time, metrics are usually updated on the dashboard within about 10 seconds.

You can select the specific functions that you want to monitor in your account, and categorise them into services and stages in order to filter your dashboard. The same set of metrics is collected for every tracked function.

Your metric data stays stored in your own AWS account. To easily view and visualise this data, log in to your account on functionmetric.com

Yes, currently you can see an overview of invocation and error counts, execution time, memory usage, and look at individual invocations and their log data. We plan to add additional features to make it even easier to see potential problems with your functions in future.

In regards to your personal and account information, see our Privacy Policy. Metrics collected about your functions stay stored in your own account, and we never generate any public credentials, so you stay chiefly responsible for their security.

These are the very next items on our roadmap :)
