If you want to perform one, just go to Perform Tests tab, select the text type, and execute it. They may take longer if the drive is not idle, and you won't be able to check SMART data while running them.
They are safe and can be done during normal system conditions. You can perform some tests to recognize drive faults.

You should check your drive's user manual first so as to know how to read Normalized, Raw, and other values (the interpretation may vary depending on the manufacturer). Those are some important attributes, you can see them all on SMART Wikipedia page. This attribute is for HDDs, and the higher value denotes that it may be suffering a mechanical problem. When a spin start is unsuccessful, this counts the attempts done to do a full-speed spin start.
Spin Retry Count: Count of retry spin start attempts. Wear Leveling Count: Shows the remaining endurance of the drive in percentage, it starts in 100 (best value) and decreases to 0 linearly as it gets written. This can help you to determine if the drive has been used intensely or not, which is useful for example if you want to buy an used drive. Power Cycle Count: Indicates the count of the drive's power on / off cycles. If you have a high value here, it's probably that your drive will fail soon. Reported Uncorrectable: This attribute represents the number of sectors that couldn't be recovered by the drive's error correction system. Reallocated Sector Count: Represents the number of sectors that couldn't be written by the SMART assessment. Tested in: Xubuntu 17.10 / Ubuntu 16.04 LTS Check hard disk health linux command Offline#
Enable / Disable Automatic Offline Data Collection.You can check the list of supported devices. This tool supports ATA drives (PATA and SATA), some USB to ATA bridges and some RAID controllers. The early detection of potential problems allows the user to get informed about the situation and make a backup and/or replace the drive before reaching the point of loosing important information. Its an acronym for Self Monitoring Analysis and Reporting Technology, a technology that makes it possible to detect HDD and SDD failures. It also allows you to run different tests. With this software, you can check the SMART data in order to determine its health. Such information can then be passed to other applications for further processing and analysis.GSmartControl is a GUI alternative for smartctl, a tool for controlling SMART data on hard disk drives and solid state drives.

You can use BigFix Inventory REST API to retrieve large amounts of data that is related to computer systems, software instances, and license usage in your environment. Follow the tips and the known solutions to these issues to keep the system in good shape and avoid performance problems. You can learn the possible causes of the most common performance issues in medium and large environments.
Tuning performance in medium and large environments. Learn about additional tasks that you might want to perform to improve the performance in your infrastructure. Additional tasks for improving performance. Learn how to improve the scanning and importing activities to optimize the performance in your infrastructure. To take advantage of the speed and scalability that is offered by BigFix, it is often necessary to tune the settings of the BigFix deployment. Using relays to increase the performance of BigFix. RAM performance metrics such as seek time or memory bandwidth, are strictly dependent on the memory type, which is linked with the processor type. You can also use the iostat command to determine average disk usage. On Linux™, you can use the hdparm and dd commands or the Bonnie++ application to determine the hard disk write rate. Learn some diagnostic methods and use them to ensure that the hardware infrastructure is in good shape. The storage performance of the BigFix Inventory server alone is not that important. To ensure good performance of BigFix Inventory, it is essential to have good storage performance on the database server computer. You must ensure that the recommended requirements are met. The main factor that affects the performance of the BigFix Inventory server is the performance of the underlying infrastructure on which the application server and the DB2 database are running. The following guidelines are applicable in big data environments as well as in smaller environments that are running on low-performance hardware. Learn how to plan the infrastructure of BigFix Inventory and to configure the application server to achieve optimal performance.
