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 Snap is available for [Red Hat Enterprise Linux (RHEL) 8](https://www.redhat.com/en/enterprise-linux-8) and RHEL 7, from the 7.6 release onward. The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective [Extra Packages for Enterprise Linux](https://fedoraproject.org/wiki/EPEL) (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below. The EPEL repository can be added to **RHEL 9** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 8** with the following command: ``` sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm sudo dnf upgrade ``` The EPEL repository can be added to **RHEL 7** with the following command: ``` sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm ``` Adding the *optional* and *extras* repositories is also recommended: ``` sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms" sudo yum update ``` Snap can now be installed as follows: ``` sudo yum install snapd ``` Once installed, the *systemd* unit that manages the main snap communication socket needs to be enabled: ``` sudo systemctl enable --now snapd.socket ``` To enable *classic* snap support, enter the following to create a symbolic link between `/var/lib/snapd/snap` and `/snap`: ``` sudo ln -s /var/lib/snapd/snap /snap ``` 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?
