SITE_NAME

SITE_NAME is a service for monitoring cron jobs and similar periodic processes:

• SITE_NAME listens for HTTP requests ("pings") from services being monitored.
• It keeps silent as long as pings arrive on time.
• It raises an alert as soon as a ping does not arrive on time.

SITE_NAME works as a dead man's switch for processes that need to run continuously or on regular, known schedule. For example:

• filesystem backups, database backups
• task queues
• database replication status
• report generation scripts
• periodic data import and sync jobs
• periodic antivirus scans
• DDNS updater scripts
• SSL renewal scripts

SITE_NAME is not the right tool for:

• monitoring website uptime by probing it with HTTP requests
• collecting application performance metrics
• error tracking
• log aggregation
