Observability platform vs. observability tools

Dynatrace

Metrics are measures of critical system values, such as CPU utilization or average write latency to persistent storage. For example, in 2005, Dynatrace introduced a distributed tracing tool that allowed developers to implement local tracing and debugging. Observability is made up of three key pillars: metrics, logs, and traces.

The Surprising Effectiveness of Non-Overlapping, Sensitivity-Based Performance Models

John McCalpin

The presentation discusses a family of simple performance models that I developed over the last 20 years — originally in support of processor and system design at SGI (1996-1999), IBM (1999-2005), and AMD (2006-2008), but more recently in support of system procurements at The Texas Advanced Computing Center (TACC) (2009-present).

Linux Load Averages: Solving the Mystery

Brendan Gregg

Nowadays, the source code to old operating systems can also be found online. Linux is also hard coding the 1, 5, and 15 minute constants. This state is used by code paths that want to avoid interruptions by signals, which includes tasks blocked on disk I/O and some locks. This, too, was a dead end. This, too, was a dead end.

Service Workers can save the environment!

Dean Hume

Electricity used by servers doubled between 2000 and 2005 (and has continued growing ever since) from 12 billion to 23 billion kilowatt hours. Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user.
