Bigpanda vs Cronitor: What are the differences?
Bigpanda: The cure for alert fatigue. Bigpanda helps you manage and respond to ops incidents faster. All your alerts: organized, assignable, trackable, snoozeable, and updated in real-time; Cronitor: Monitor cron jobs, daemons and almost anything else. Monitoring systems are often complex and require a strong sysadmin background to properly configure and maintain. Cronitor replaces all this with a simple service that anyone can set up. Receive email/sms notifications if your jobs don't run, run too slow, or finish too quickly.
Bigpanda and Cronitor can be categorized as "Monitoring Aggregation" tools.
