Analyzing API Call Performance from Different Global Locations Based on cURL Metrics

My previous post presented “A Graphical View of API Performance Based on Call Location.” In that post, we analyzed the performance of a week of calls to the World Bank Countries API (which is served from Washington DC) from four different locations around the globe: Washington DC USA, Oregon USA, Ireland, and Tokyo Japan. The API performance across the week showed remarkable consistency. Calls to the API from Washington DC had by far the best performance; calls from Ireland generally outperformed calls from Oregon, which generally outperformed calls from Tokyo. Here’s the data for the week (the Y axis is logarithmic)

A Graphical View of API Performance Based on Call Location

The performance of APIs is dependent on both the processing time from when the API receives a request and delivers a response, and the time it takes for the request and response data packets to traverse the Internet distance between the calling system and the system that hosts the API. The timings for calls to […]

Configuring API Monitors for Specific Response Formats

Global variables can be utilized to store any kind of data that is needed as a reference resource within a complex API monitoring process. For example, global variables can be created by one API monitor, then that data store can be read as input data by another API monitor. In my post Introduction to API […]

Monitoring Your API’s Performance Using the API Science API

If your product depends on your own internal API, or if your primary customers are users who use your API, then you need to know when your API’s performance is experiencing problems. In my last post I described how you can use the API Science Uptime Report to address an unexpected massive outage related to […]

What to Do when a Massive Cyber Attack Brings Down APIs

In mid-May, a massive global cyber attack was executed that affected major companies in more than 150 countries. Major victims of the attack included Britain’s National Health Service, “causing widespread disruptions and interrupting medical procedures across hospitals in England and Scotland.” Other major victims included Spain’s Telefonica, Deutsche Bahn (Germany’s national railway service), French carmaker […]

Using the Weekly API Science Report to Improve Customer Experience

Your API Science account automatically provides you with the “Weekly API Science Report” which is delivered by email to the email address associated with your account. Here’s an sample email for an account that runs two API Science monitors: The report proceeds from a performance overview for all of your monitors down to the details […]

Timing-Out Slow-Performing External API Requests

API performance varies depending on many variables, including the response of the Internet (for example, resolve time and transfer time) and the timing for work that occurs on the remote server (connect time and processing time). My last post illustrated that calls to the World Bank Countries API sometimes exhibit abnormally slow performance. Unpredictable, though […]
