sysstat, alternative Linux à Wise Memory Optimizer
Mis à jour le
Notre avis
sysstat is a solid replacement for Wise Memory Optimizer if you are comfortable with command‑line tools and need detailed historical data. It provides real‑time and logged memory usage, per‑process stats, and a system‑wide overview, but it lacks a graphical interface and the automatic cache‑clearing feature of Wise Memory Optimizer. It suits power users, sysadmins, and those who want to script or log memory metrics, not casual users who prefer a simple GUI.

- It does not offer a dedicated cache‑clearing feature
Ouvrir vos fichiers Wise Memory Optimizer
Wise Memory Optimizer does not produce standard log or configuration files that sysstat can read. There is no direct way to import its data into sysstat. You would need to export Wise data to a CSV or text format manually, then parse it with a custom script if you want to compare it with sysstat logs.
Passer de Wise Memory Optimizer à sysstat, étape par étape
- Install sysstat using your distro’s package manager (e.g., apt install sysstat).
- Enable data collection by editing /etc/default/sysstat and setting ENABLED=1, then restart the sysstat service.
- Run sar -r 1 5 to view real‑time memory usage; use sar -r -f /var/log/sysstat/saXX for historical data.
- Use pidstat -r -p ALL to see per‑process memory usage.
- Optionally install htop or btop for a visual, interactive view of memory usage.
