Healthchecks, the open source cron job monitoring service: your scheduled tasks ping it over HTTP and it alerts you when a ping goes missing. Preinstalled with gunicorn and nginx; a per instance administrator account is generated on first boot. Backed by 24/7 cloudimg support.
## Healthchecks by cloudimg
Healthchecks is the popular open source cron job monitoring service - a dead man's switch for your scheduled tasks. Every cron job, backup script, certificate renewal or batch process gets its own unique ping URL; the job requests that URL when it completes. If a ping does not arrive on schedule, Healthchecks flags the check and notifies you by email, Slack, Discord, Telegram, PagerDuty, webhooks and dozens of other integrations. Unlike active uptime probing, this passive model catches the jobs that silently stopped running. This Amazon Machine Image delivers Healthchecks fully installed and configured, so a complete cron monitoring platform is running within minutes of launch. The current release available is Healthchecks v4.2.
## Application Stack
Healthchecks runs bare-metal from the official release: the Django application is served by gunicorn behind an nginx reverse proxy on port 80, and the alert delivery daemon (sendalerts) runs as its own system service so notifications are sent the moment a check changes state. The database is SQLite on a dedicated data volume, the upstream-supported default for single-node deployments, keeping the appliance lean with no separate database server to manage.
## Secure By Default
On the first boot of your instance a one-shot service generates a fresh Django secret key and a fresh administrator password, unique to that instance, and writes them to a root only file. The instance's own address is configured as the site root automatically and open registration is disabled, so only the administrator can sign in or invite users. No shared or default credentials ship in the image.
## Ready To Use
The application, web server and alert daemon are all configured, with the application and its database on a dedicated, independently resizable storage volume. Browse to the instance address, sign in as the administrator, create your first check and add its ping URL to a cron job.
