![]() It will now display information particular to that canary. To view specific canary information, such as availability, click on the canary's name. If all goes as planned, you will be taken to the Canary page, where your canary will be displayed under the Canary option. The API canary may take a minute or two to construct. Leave the rest of the parameters at their defaults and click " Create canary". You can also instruct Canary to establish a new access authorization role or pick an existing one. Leave the Data Retention option at its default setting of 31 days.Īfter that, either leave the Data Storage option for the test artifacts at the default S3 location or adjust it to your preferred place. You can choose between " Run Continuously," " CRON expression," and " Run Once." We'll choose " Run Continuously" and set the run frequency to every 30 minutes. Select how frequently you want the canary to run under the Schedule box. For demonstration purposes, we'll leave it blank. Use the Environment Variable option if you need to send in environment variables. Give your step a name, and when finished, click the "Save" button. We will make a GET API call for demonstration purposes. Please keep in mind that no uppercase characters can be used in the name.Īdd the API HTTP request details, such as end point, Method, Request Data, and Headers, to the HTTP request option. Let's call it "canarycry" for the sake of demonstration. ![]() Under Create canary, select " Use a Blueprint" option and under Blueprint, select " API canary" Navigate to Synthetic Canaries from the Cloudwatch service and click Create Canary option. GUI Workflow - The GUI Workflow Builder blueprint verifies that actions can be taken on your webpage.įor further detail on each of these blueprints, refer to this link.Canary Recorder - With the canary recorder blueprint, you can use the CloudWatch Synthetics Recorder to record your click and type actions on a website and automatically generate a Node.js script that can be used to create a canary that follows the same steps.Visual Monitoring - The visual monitoring blueprint includes code to compare screenshots taken during a canary run with screenshots taken during a baseline canary run.Broken Link Checker -The broken link checker collects all the links inside the URL that you are testing.API Canary - API canaries can test the basic Read and Write functions of a REST API.Heartbeat Monitor - Heartbeat scripts load the specified URL and store a screenshot of the page and an HTTP archive file.The remainder of this post will provide a quick introduction of the various types of canary blueprints as well as instructions on how to set up an API canary.įollowing canary blueprints are available for synthetic monitoring. Other two are the inline editor and Import from S3, if you have your own synthetic monitoring scripts. They monitor REST APIs, URLs, and website content, and they can check for unauthorized changes from phishing, code injection and cross-site scripting.ĪWS provides three options for creating canaries. They support both the HTTP and HTTPS protocols.Ĭanaries also offer programmatic access to a headless Google Chrome Browser via Puppeteer or Selenium Webdriver.Ĭanaries check the availability and latency of the endpoints and can store load time data and screenshots of the UI. In your account, they create Lambda functions that leverage Node.js or Python framework. Canaries can be set to run on a set schedule.Ĭanaries' current versions are scripts written in either Node.js or Python. Canaries are programmable scripts that follow the same paths and do the same activities as customers, allowing you to validate your customer experience even when there is no client traffic on your apps. These actions or journey are then continuously monitored at specified intervals for performance, functionality and availability measures.Īmazon CloudWatch now allows you to monitor your endpoints and APIs by creating canaries using Cloudwatch Synthetics. Synthetic monitoring is also known as active monitoring or proactive monitoring. Script(s) are used to imitate action or journey that a user would take on a application, website or system. Synthetic monitoring is a type of monitoring that involves the use of emulation or scripted recording of transactions. AWS Cloudwatch synthetic monitoring with canaries is one of those Easter eggs. Every time you look at an AWS service, you'll discover a slew of hidden Easter eggs.
