ResponseTime Monitor

Shows the response times of up to three webservers. Useful to see how the internet/server connection performs.

ResponseTime Monitor is a handy Chrome extension that tracks and displays the response times of up to three webservers, helping users monitor their internet and server connection performance. It presents the last 31 response times in a clear, visually appealing chart where higher bars indicate slower responses, and red bars signify timeouts.

This tool is essential for quickly assessing server load and internet stability. A consistent bar height shows a healthy connection, while mixed red and blue bars or high volatility suggest instability or server overload. The extension requires permission to access 'Your data on all websites' to enable accurate response time checks for user-specified URLs, ensuring comprehensive monitoring across any chosen servers.

User reviews

ResponseTime Monitor is praised for its simplicity and effectiveness in monitoring internet connection quality and latency, especially on Chromebooks. Users appreciate its quick display and minimal design. However, consistent issues include the lack of average response time calculations, inability to toggle the extension on or off, and unreliable outage detection on Windows PCs. Users also desire additional features like log file output and notification alerts for sustained connectivity problems.

Pros

Simple and minimalistic design making it easy to use.
Effectively monitors internet connection quality and network latency.
Works well on Chromebooks and some PCs.
Provides quick and straightforward display of internet connection status.
Useful tool for tracking response times and overall network performance.

Cons

Lacks the ability to compute average response time over a period of time.
No option to enable or disable the extension (on/off switch).
Does not reliably detect internet outages on Windows PCs—color indicator remains blue even when offline.
Limited features such as absence of log files or notifications for consecutive timeouts.

It seems to have two major issues: it does not compute average response time for a period of time. The second problem is there is no way to enable and disable this extension, like on/off.
