## What it is
Sysstat is a collection of Linux performance monitoring utilities including sar, iostat, mpstat, pidstat, tapestat, and cifsiostat. It collects, reports, and historizes system activity data such as CPU, memory, disk I/O, and network statistics, with export to CSV, XML, JSON, and SVG formats.

## Use cases
- monitor cpu and disk io usage on a linux server
- collect historical system performance data with sar
- find which process is consuming cpu or memory with pidstat
- export system activity metrics to  or csv
- troubleshoot slow disk io on linux
- generate graphs of server activity over time

## When to choose
- you need lightweight, native Linux performance monitoring from the command line
- you want to historize system activity data via cron or systemd for later analysis
- you need per-CPU, per-device, or per-process statistics without installing agents

## When to avoid
- you need monitoring of non-Linux systems
- you want a web dashboard or alerting system rather than CLI tools
- you need application-level or container-level metrics

## Facets
- artifact type: cli-tool
- maturity: stable
- function: monitoring, analytics
- domain: monitoring, performance
- platform: cli
- tags: sar, iostat, mpstat, pidstat, system-performance, historical-data-collection, devops, command-line, linux
