Disable System Statistics Reset Service (sysstat)

service_sysstat_disabled

Description

The sysstat service resets various I/O and CPU performance statistics to zero in order to begin counting from a fresh state at boot time. The sysstat service can be disabled with the following command:

$ sudo systemctl mask --now sysstat.service

Rationale

By default the sysstat service runs a program at boot to reset performance statistics. This data can be retrieved using programs such as sar and sadc. While the sysstat service may provide useful insight into system operation, through the lens of providing only essential system services, this service should be disabled.
