Apollo

Apollo is a server, website & SSL monitoring tool that alerts users when an SSL certificate is about to expire or when downtime has been detected on your website or server. What makes Apollo so unique is the ability to SSH into your server when downtime is detected and perform routine tasks to get your server or website back to full health. This gives your developers and server managers much more time to react and find a better solution for the problem causing the downtime. Apollo also sends notifications to Slack, Pushover, Email and can even send tweets out for you to make your audience aware of downtime.
