User metrics are measurements that show how people interact with a product, service, or website. They track things like how many users visit, how long they stay, and what actions they take. These metrics help businesses understand user behaviour and improve their offerings. By analysing user metrics, organisations can make better decisions about design, features,…
An output archive is a collection or storage location where the results or products of a process are saved for future use, review or distribution. This could include files, documents, images or data generated by a computer program, scientific experiment or business workflow. Output archives help to organise, protect and provide easy access to important…
A rate limiter is a tool or technique used to control how often a particular action can happen in a set period of time. It is commonly used in computer systems to prevent overuse or abuse of resources, such as APIs or websites. By setting limits, it helps maintain system stability and ensures fair access…
A session tracker is a tool or software feature that records and monitors user activity during a specific time period, known as a session. It helps websites and applications remember what a user does, such as pages visited or actions taken, while they are logged in or browsing. This information is often used to improve…
An API monitor is a tool or software that observes and tracks the activity of Application Programming Interfaces (APIs). It checks if APIs are working as expected, monitors their response times, and detects any errors or issues. By monitoring APIs, developers and businesses can ensure their applications are reliable and identify problems quickly.
Throughput analysis is the process of measuring how much work or data can pass through a system or process in a specific amount of time. It helps identify the maximum capacity and efficiency of systems, such as computer networks, manufacturing lines, or software applications. By understanding throughput, organisations can spot bottlenecks and make improvements to…
Latency sources are the different factors or steps that cause a delay between an action and its visible result in a system. These can include the time it takes for data to travel across a network, the time a computer spends processing information, or the wait for a device to respond. Understanding latency sources helps…
Peak usage refers to the time period when the demand for a service, resource, or product is at its highest. This can apply to things like electricity, internet bandwidth, water supply, or public transport. Understanding peak usage helps organisations plan for increased demand, prevent overloads, and provide a better experience to users.
A cache hit occurs when requested data is found in a cache, which is a temporary storage area designed to speed up data retrieval. Instead of fetching the data from a slower source, such as a hard drive or a remote server, the system retrieves it quickly from the cache. Cache hits help improve the…
Server spikes occur when the demand on a computer server suddenly increases for a short period. This can be caused by many users visiting a website or using an online service at the same time. If the server is not prepared for this extra demand, it can slow down or even crash, affecting everyone trying…
