I like tools that can help me to stay on top of things without requiring too much time investment.

Robotalp has been very easy to configure and since then it lets me know when the website is down so I can quickly check it out.

I like the fact there are multiple monitor types available and I can customise the duration.

For me this is a great tool to add to my stack and I particularly like the uptime page. This is a great way for me to easily show to my site visitors how stable the site is and it updates in real time.

There are lots of new features being added all the time however this is the type of tool that is something you should consider getting because it's better to be in a position where your website is being regularly monitored so if for any reason it does you down, you can react quickly to avoid disruption to customers.
