An independent Linux alternative inspired by Hard Disk Sentinel for continuous storage health inspection, kernel block queue analysis, live disk I/O telemetry, and filesystem capacity alerts in user space without requiring raw block-device access. Key Features: * Kernel Block Inspector (/sys/block/\*): Reads real drive model, vendor, firmware revision, sector capacity, SSD/HDD rotational indicator, active I/O scheduler, queue depth, logical/physical sector sizes, and TRIM/discard granularity. * Live Disk I/O Telemetry (/proc/diskstats): Tracks cumulative reads/writes, sectors transferred, active I/O milliseconds, live MB/s throughput, IOPS, and utilization curves in real time. * NVMe & Hardware Thermal Sensors: Reads /sys/class/nvme/\* controller status and /sys/class/hwmon/\* drive temperature sensors when exposed by the kernel. * Mount Space Watchdog (os.statvfs & /proc/mounts): Monitors partition capacity, inode usage, read-only mount states, and configurable warning/critical space thresholds, plus safe temporary file SHA-256 read/write latency verification and CSV/JSON/TXT report export.

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 TC Disk Sentinel To install TC Disk Sentinel, simply use the following command: ``` sudo snap install tc-disk-sentinel ``` ### 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?
