Healthchecks.io is a cron job monitoring service. It helps you fix small issues before they turn into disasters.  Healthchecks.io works by listening for HTTP requests and email messages ("pings") from your cron jobs and scheduled tasks ("checks"). When a ping
does not arrive on time, Healthchecks.io notifies you. The benefits of this monitoring method:• No notification spam. Healthchecks.io keeps silent when everything is running smoothly, and only notifies you when something does not run as expected.
• Can catch many types of failures: when a cron job exits with non-zero exit code, when the monitored system loses network connection (as so is unable to notify about any failures on its own), when the monitored system is completely offline due to, say, a power cut.Healthchecks.io integrates with Slack and can post rich notifications to your nominated Slack channel or user.Healthchecks.io is used both in professional environments to monitor servers and services in datacenters, and in DIY setups to monitor residential internet connections, Raspberry PIs, power cuts in summer houses, and services in homelabs.
