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.

They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd If you’re running [Ubuntu 16.04 LTS (Xenial Xerus)](https://www.ubuntu.com/) or later, including [Ubuntu 18.04 LTS (Bionic Beaver)](https://www.ubuntu.com/desktop/features) and [Ubuntu 20.04 LTS (Focal Fossa)](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes), you don’t need to do anything. Snap is already installed and ready to go. For versions of Ubuntu between [14.04 LTS (Trusty Tahr)](https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes) and [15.10 (Wily Werewolf)](https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes), as well as Ubuntu flavours that don’t include *snap* by default, *snap* can be installed from the Ubuntu Software Centre by searching for *snapd*. Alternatively, snapd can be installed from the command line: ``` sudo apt update sudo apt install snapd ``` Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly. ### Install Disk Writeback and Sync Monitor To install Disk Writeback and Sync Monitor, simply use the following command: ``` sudo snap install dirty-cache-flusher ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
