Choosing a REST API Monitoring Tool
Having a solid API monitoring system is pretty much mandatory for any organization’s environment that runs its own web services. The loss of API functionality could result in thousands of dollars of lost revenue.
While there’s clearly plenty of choices when it comes to filling your REST API monitoring needs, some tools shine brighter than others. I find Loggly to strike the best balance between usability, flexibility, functionality, and price.
AlertSite is a great runner up, with a clean user interface, multiple alerting configurations, and codeless element based testing. Not all monitors may suit your needs so be sure to take full advantage of any free trials that may be available.
REST API Monitoring FAQs
🎛How to check the health of REST API?
Health checking functions vary depending on the API being used. The best way to track the health of a REST API is through an API monitoring tool, such as those listed in this article.
👍What are some good ways to track API usage?
API usage tracking functions depend on the ownership of the API you want to track. If the API is a partner tool from one of your own programs, you need to integrate access logging within the API code, writing to a log file on your server every time the API is accessed. If you have deployed an API from a utility owned by someone else and want to record how many times that piece of code is activated, you will need to associate a logfile record generating function with the triggering of the API.
🤔What is the difference between REST API and RESTful API?
REST stands for “Representational State Transfer” and it is an architecture of application interface that is based on existing Web technologies and protocols, such as HTTP. The term “RESTful” simply means “written in the REST style.” So, the terms REST API and RESTful API are more or less interchangeable.
