Split + Grafana
You can send audit log notifications to Grafana as chart annotations. This Split audit log webhook abridges notifications into chart annotations for Grafana. The annotations are tagged as split so that a Grafana user can put an annotation query on any dashboard to see Split notifications. You can read about Grafana Chart Annotations. A single node.js lambda does the work for the integration, using only the filesystem (for API keys) and the Axios HTTP client. The integration receives audit log notifications, abridges them into new annotations, and calls the Grafana annotation API to create new annotations.
Before you start, you should be familiar with AWS and working with Lambdas.
Installing the Split audit log webhook
The Split audit log webhook is a node.js lambda, which is designed to be deployed in AWS. To install the webhook on your local environment, do the following:
- Clone the Split Grafana repository in an empty directory.
- In the directory, carefully copy your Grafana API key into a file called GRAFANA_API_KEY (I used admin role key).
- Copy the host and port of your Grafana server into a file called GRAFANA_URL.
Copy the host and port of your Grafana server into a file called GRAFANA_URL. For example:
3000 is the default port. Change this to the proper host and port of your Grafana server. The host must be accessible from AWS. Local installs won’t be visible to the integration lambda.
Note: Be sure you don’t copy or add a trailing slash. If you add an extra space or trailing slash at the end of the line, or empty lines after, the key won’t be recognized and the integration fails to run correctly. In addition, the file names must precisely be the names as shown above, including being all caps.
- From this directory, use a terminal to do the following. If npm is not installed, install it:
> npm install
> zip -r grafana.zip *
The grafana.zip now includes the index.js, the Grafana key and url files, and a full node_modules directory.
Note: You can also "brew install npm" on OSX. Follow the instructions to install npm for other operating systems.
Creating an annotation query for tag split
You must create an annotation query for tag split on the dashboards for where you want the Split annotations to appear. Refer to the Grafana documentation for information about dashboard settings. Once you set this up, you see the following:
The following shows you an example of what you see when you click the Preview in dashboard button:
Installing in AWS
To install Grafana in AWS, do the following:
- Create a new "split2grafana" lambda for Nodes.js.
- Upload grafana.zip to the Code screen of your AWS lambda.
- Once you create a lambda, create a functional URL to POST to it.
- Enable CORS and give the Allow Headers field an *
- Provide the functional URL to a new Split audit log webhook.
- Use the Split webhook test button to make sure you get back a 200 response from your lambda.
- Once done, to test this, make a change to a feature flag and save it.
Use CloudWatch to look at inbound events and check they're properly handled. Incorrect key or Grafana server host and port are likely problems.
