System Resource and Process Monitoring History Daemon
Atop is an ASCII full-screen performance monitor, similar to the top
command. At regular intervals, it shows system-level activity related to
the CPU, memory, swap, disks and network layers, and it shows for every
active process the CPU utilization in system and user mode, the virtual
and resident memory growth, priority, username, state, and exit code. The
process level activity is also shown for processes which finished during
the last interval, to get a complete overview about the consumers of things
such as CPU time. Atop only shows the active system-resources and processes,
and only shows the deviations since the previous interval.
This subpackage contains the permanent monitoring daemon, to store history
information about processes and system resources.
Paths come from the repository package-file index for the observed builds. They describe archive/package associations, not every file that will exist on a running system after maintainer scripts, alternatives, generated state, diversions, or installation choices.
Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.
