Hi, I’m Matt Anderson.

I build practical tools and notes around Linux, networking, performance analysis, and operations work.

Featured Tool

SARkart

My latest featured project: a fast browser-based viewer for Linux and Unix SAR files that keeps the analysis local to your machine.

Performance triage for SAR/sysstat files

SARkart is built for the moment when someone hands you a SAR text file and asks what happened. Drop in the file, inspect the charts, and copy a concise summary into a ticket or case note.

TypeScript Preact Plotly.js Linux SAR Client-side parsing
  • Interactive charts for CPU, memory, disk, network, load, and process activity.
  • Deterministic bottleneck checks ranked by severity and incident timing.
  • Local browser parsing so uploaded SAR files stay on the user’s machine.
  • PDF export, heatmaps, command palette, and copy-ready support summary.
