Catching Faults Missed by APM and Monitoring tools

August 19, 2019 | Ajay Singh

As software gets more complex, it gets harder to test all possible failure modes within a reasonable time. Monitoring can catch known problems – albeit with pre-defined instrumentation. But it’s hard to catch new (unknown) software problems. 

A quick, free and easy way to find anomalies in your logs

Deploying into Production: The need for a Red Light

July 23, 2019 | Larry Lancaster

As scale and complexity grow, there are diminishing returns from pre-deployment testing. A test writer cannot envision the combinatoric explosion of coincidences that yield calamity. We must accept that deploying into production is the only definitive test.

Using ML to auto-learn changing log structures

July 14, 2019 | David Adamson

Software log messages are potential goldmines of information, but their lack of explicit structure makes them difficult to programmatically analyze. Tasks as common as accessing (or creating an alert on) a metric in a log message require carefully crafted regexes that can easily capture the wrong data by accident (or break silently because of changing log formats across software versions). But there’s an even bigger prize buried within logs – the possibility of using event patterns to learn what’s normal and what’s anomalous. 

Why understand log structure at all?
