#### Linux page cache, dirty writeback telemetry & kernel sync utility

Disk Writeback and Sync Monitor is a desktop page-cache telemetry viewer and
kernel filesystem buffer sync utility for Linux workstations and removable
storage workflows. An independent Linux alternative to command-line disk flush
tools such as Sync, sync(1), and vmstat, it monitors live kernel dirty buffers
and executes measured os.sync() and targeted os.fsync() flushes.

Key Features:

* Live Page Cache & Writeback Telemetry: Reads /proc/meminfo (Dirty, Writeback,
  WritebackTmp, Cached, Buffers, Active(file), Inactive(file), SReclaimable) and
  /proc/vmstat (nr\_dirty, nr\_writeback, nr\_written, pgpgin, pgpgout) in real time.
* Measured Kernel Sync & Targeted fsync: Triggers system-wide os.sync() or
  directory/file os.fsync() operations while recording exact flush latency (ms)
  and pre/post Dirty KB deltas in an execution log.
* Kernel VM Writeback Policy Inspector: Displays live /proc/sys/vm thresholds
  including dirty\_ratio, dirty\_background\_ratio, dirty\_expire\_centisecs, and
  dirty\_writeback\_centisecs alongside mounted filesystem capacity stats.
* Time-Series Charts & Reports: Plots live Dirty/Writeback KB history and page
  cache composition charts and exports telemetry and sync logs to CSV and JSON.
