A recent post analyzed API performance by hour of day over a one-week period. The average performance of calls to the API was fairly consistent, except for calls made in the last hour of the day (the hour before Midnight Universal Time). The question is: why was average performance so much worse during the last hour of the day? To gain deeper insight into the characteristics of the data, we’ll compute statistics (minimum, maximum, mean, and standard deviation) for the raw data in each hour-of-day bin. First, we initialize several Python NumPy arrays…

Analyzing API Performance by Day of Week
My last post showed how the API Science API can be utilized to create a graphical analysis of API performance binned by hour of day. In this post, we use data extracted from the API Science API to analyze the performance of an API by day of week. This type of analysis would be useful […]

Performance data from the API Science API can be analyzed in many different ways. For example, a recent post presents A Graphical View of API Performance Based on Call Location. The analysis uses cURL statistics to compare the performance of monitors that call the World Bank Countries API from various locations around the globe over […]

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 […]

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 […]

Previous posts described how to use curl, cron, JSON, Python, matplotlib, and HTML to create an automatically-updated custom API performance web page. In addition to providing API performance data, the API Science API also provides uptime data for the APIs you monitor. In this post, I’ll demonstrate how to download API uptime data and create […]
Continue readingHow to Validate Your API Using API Science’s API Analysis Platform
You’ve got a product that requires many nines of uptime. If an API (external or internal) that your product requires is down, your own product is down, or key aspects of it are down. This article describes how you can utilize the API Science API to assess problems as they occur, and alert your team […]

Your business likely requires customized views of the data that is core to the creation of your product. Decades ago, accomplishing this involved development of large data analysis software libraries that were customized to a company’s particular needs, along with user interfaces that enabled employees to view the data, so they could respond to anomalies. […]

For your company to succeed, your API-based product must provide maximal performance and uptime to your customers. In order to provide this, you need to monitor the APIs (both internal and external) that are critical for your product’s customer experience. This series of posts illustrates how you can create a custom automated web site that […]

In my previous two posts, I illustrated how your team can Use cron and curl to Regularly Download API Performance Data and How to Use Python to Extract API Performance Data. In this post, I illustrate how you can use the Python MatPlotLib library to create plots of the downloaded data that will be of […]
