Website uptime testing

Uptime monitoring means AgentSlug actively checks whether your website is up or not.

Once you set up the URL of your website, you will get notifications via e-mail or Slack every time our robots detect confirmed downtime..

We monitor websites from different locations in Europe, America, Asia and Australia so you can also compare how user location affects performance of your website.

Application monitoring

With Application Monitoring AgentSlug waits for your application to tell whether it's healthy or not.

For example, if you worker executes something every hour, it would send a signal to our API. When there is no signal for a given time, you get a notification.

You can configure how often this signal has to be sent to recognise the app working correctly.

Setup is simple and will work in every environment that is able to send an HTTPS POST request to api.agentslug.com. Please find more information about it on the application monitoring documentation page
