Are your logs helping you, or are they just creating more work? If you’re sifting through endless data but still missing the important details, you’re not alone. It’s a common challenge—but one that can be solved. For anyone managing infrastructure, logs are essential. They show what’s happening, what’s broken, and sometimes even why. But without the right approach, they can easily turn into clutter instead of clarity.

Imagine trying to find a friend in a packed stadium with 50,000 people versus spotting them in a quiet coffee shop. That’s the difference between high and low cardinality data. And if you’re working with distributed systems or microservices, this isn’t just a theoretical distinction—it’s a fundamental challenge that can make or break your observability setup.

In the early days of DoubleClick, back when SaaS was still known as Application Service Provider (ASP), I was tasked with setting up the QoS (Quality of Service) Team. Our primary mission was to establish a monitoring system, but we quickly found ourselves managing Service Level Agreements (SLAs)—a task that became critical after we paid out over $1 million in penalties for SLA violations to a single customer. The reason? Someone had signed a contract promising 100% uptime, an impossible commitment.

Nobody likes being left in the dark when a service goes down. We can imagine how frustrating it is to refresh a page repeatedly, wondering if the issue is on your end or if something bigger is happening.
