Getting Started

Create an account

You can create a functionmetric account for free, simply:

  • go to
  • click log in, and choose the sign-up option
  • sign up with your email address and create a password, alternatively - log in with your Google or GitHub account.

Create an organisation

You'll be prompted to create your organisation, which you will be able to use to share metrics with your team.

Create organisation prompt

Enter your organisation's name, or for personal use, whatever you like!

You can also create your first service here, so enter the name of one of your applications you want to monitor. You can change this or add more services later.

You can also create a stage, which refers to the specific environment you'll be setting up first. Usually this will be something like 'dev', 'test' or 'prod'.


Integration, service and stage names must be less than 50 characters, can only contain upper and lowercase letters, numbers, spaces, dots, hyphens and underscores.

Connect your AWS account

You'll now be prompted to connect your AWS account. Simply enter a name for the account you'll be adding, and select it's region. If you have an account to separate dev and test environments from production, this might be something like "org-dev".

Create organisation prompt

Click connect, and we'll generate you a link to follow which will create your integration in your account on AWS.

Deploy CF Template

Follow the link to create the CloudFormation template.


Installing the CloudFormation template will increase your AWS Bill by a negligible amount.

Within AWS, Scroll to the end of the CloudFormation create stack page, avoid changing any of the pre-filled parameters. You'll need to check the box to acknowledge that the template will create IAM roles and policies to grant access to your metrics.

Deploy CF Template

Hit "Create Stack". You can now return to functionmetric and click "Continue". functionmetric will now wait for your stack to finish creating, which might take a few minutes. When this completes, the page will update automatically.

Wait for deployment

You can add additional accounts later.

If you run in to any issues at this point, first check the CloudFormation events tab for any errors. If you need assistance, get help on Discord or contact us via email.

Configure functions you want to monitor


Each source you monitor will increase your AWS Bill depending on how often the function is invoked, and the retention period of data.

You'll now be able to see the detected metric sources in functionmetric. If you can't see all your functions yet, click the refresh button at the top right of the table to detect the available functions automatically.

Configure Sources

Select any functions you'd like to monitor and edit their status by clicking the blue "Pending" button.

Edit Source

Set the status to Active, and select a service and stage for this function which will categorise and help you later to filter the log metrics you're interested in viewing.


If you encounter a "This log group has too many existing subscriptions" error, you can follow this guide to resolve the issue.


If you have several functions you would like to activate, deactivate or recategorise into a different service or stage, you can select them using the checkboxes to the left of each item, and then click the edit button at the bottom of the screen.

Edit Source

Your selections are preserved should you wish to use the search feature on the table.

Monitor your function executions

You can now click on the "Functions" item in the top nav bar, and you should see any sources you set to active in the previous step.

Depending on how often your function gets executed, metrics might not appear straight away. If you can, execute some of your functions to check that you can see the invocation count increasing.

Edit Source

That's it! You've set up your first integration with functionmetric!
