# Scrutiny for YunoHost [](https://dash.yunohost.org/appci/app/scrutiny)   [](https://install-app.yunohost.org/?app=scrutiny) *[Lire ce readme en français.](./README_fr.md)* > *This package allows you to install Scrutiny quickly and simply on a YunoHost server. If you don't have YunoHost, please consult [the guide](https://yunohost.org/#/install) to learn how to install it.* ## Overview WebUI for smartd S.M.A.R.T monitoring > NOTE: Scrutiny is a Work-in-Progress and still has some rough edges. # Introduction If you run a server with more than a couple of hard drives, you're probably already familiar with S.M.A.R.T and the `smartd` daemon. If not, it's an incredible open source project described as the following: > smartd is a daemon that monitors the Self-Monitoring, Analysis and Reporting Technology (SMART) system built into many ATA, IDE and SCSI-3 hard drives. The purpose of SMART is to monitor the reliability of the hard drive and predict drive failures, and to carry out different types of drive self-tests. Theses S.M.A.R.T hard drive self-tests can help you detect and replace failing hard drives before they cause permanent data loss. However, there's a couple issues with `smartd`: - There are more than a hundred S.M.A.R.T attributes, however `smartd` does not differentiate between critical and informational metrics - `smartd` does not record S.M.A.R.T attribute history, so it can be hard to determine if an attribute is degrading slowly over time. - S.M.A.R.T attribute thresholds are set by the manufacturer. In some cases these thresholds are unset, or are so high that they can only be used to confirm a failed drive, rather than detecting a drive about to fail. - `smartd` is a command line only tool. For head-less servers a web UI would be more valuable. **Scrutiny is a Hard Drive Health Dashboard & Monitoring solution, merging manufacturer provided S.M.A.R.T metrics with real-world failure rates.** # Features Scrutiny is a simple but focused application, with a couple of core features: - Web UI Dashboard - focused on Critical metrics - `smartd` integration (no re-inventing the wheel) - Auto-detection of all connected hard-drives - S.M.A.R.T metric tracking for historical trends - Customized thresholds using real world failure rates - Temperature tracking - Provided as an all-in-one Docker image (but can be installed manually) - Configurable Alerting/Notifications via Webhooks - (Future) Hard Drive performance testing & tracking **Shipped version:** 0.6.0~ynh1 ## Screenshots  ## Documentation and resources * Official app website: * Official admin documentation: * Upstream app code repository: * YunoHost documentation for this app: * Report a bug: ## Developer info Please send your pull request to the [testing branch](https://github.com/YunoHost-Apps/scrutiny_ynh/tree/testing).
