Deep dives into infrastructure, security, and design from the engineers building the world's sharpest monitoring platform.
Why SSL certificates still expire — and how to catch it in time
Automatic renewal made expired certificates rare, not impossible. The ways renewal quietly fails, what an SSL monitor checks, and the settings that give you time to fix it.
Cron job monitoring: know when a scheduled job didn't run
