WatchSumo

Sumo helps you keep track of website issues by monitoring uptime and sending instant notifications of any problems via email or webhook. It's perfect for both in-house website development teams and website developers who need to monitor their clients' websites. Sumo comes with a simple dashboard that shows the status of every website you've added at a glance, including current state and response time. Once you've bought a plan, you can add as many websites as you want without any limit. Just add a URL and Sumo will start tracking it. All the data will be presented in elegant graphs that show the performance of each website, including: Last 24 Hours Availability, Last 7 Days Availability, Last Month Availability, Last 7 Days Mean Response Time, Last Month Mean Response Time, Last Response Details, and more.
