How to use Linux standard tools for monitoring

[Aahlaadith]

Linux users must be knowing that hard drives can always give up the ghost. Even if servers in this scenario usually cushioned by RAID systems, it is useful to detect defective hard disks as soon as possible and replaced. Please tell me how to use Linux standard tools for monitoring and alerts ?? I know that you will provide me replies sooner, but along with that I am expecting that you members to provide some information about an automated monitoring.

Hard drives are not an integral part of the computer world. It is often neglected, that they do not work forever - in fact, sometimes they hang from one moment to another. Sometimes they give but also signals that they will reach the end of their deployment. With the right resources can monitor hard drives, and administrators can be automatically informed about defects. Linux brings some free agent with the board to provide, properly configured, well.

SMART is an acronym for Self-Monitoring, Analysis and Reporting Technology - a technology that is included in all modern hard disks. In Linux, these services can be with the smartmontools claim take. The package provides two programs to the daemon smartd and smartctl command line program. By his own statement, the software supports ATA, ATAPI, SATA -3 - to 8-SATA and SCSI hard drives. Likewise, the tools supported tape drives. The smartmontools are not only for Linux. You can also Mac OS X, FreeBSD, OpenBSD, NetBSD, Solaris, OS / 2, Cygwin, QNX, eComStation and Windows to be usable. With most Linux distributions, see the software package in the repositories. With the usual suspects such as YaST, aptitude, apt-get and Synaptic, the tools should be easily re-install itself.

Those who only occasionally on the condition of their hard drives will inquire, not in the background of the smartd daemon must have run. Information obtained alternatively in smartctl. This can also find out if the hard drive is used at all SMART capable and supported. Under Linux, this would go as root for the hard disk / dev / sda for example, like this (you want to look at other mass storage, you have to / dev / sda with the appropriate designation replace you):

smartctl -i /dev/sda

If your device supports, you can perform a series of tests. smartctl -t offline /dev/sda out immediate offline test by one. This does not mean that the disk is unmounted. The tool then shows you at a time when the test is expected to be completed. You can search this time using smartctl -l error assess the result. Using parameter -t, you can the entire disk instead of just certain areas to test. What do the smartctl parameters in detail, and for what types of disks are used, please refer to the so-called smartctl manpage of which are on the command line using man smartctl can call.

Since, you also wanted to know about the automated monitoring, I thought to provide some information about it. In Ubuntu 8.04 and Debian-based distributions probably all you need to edit two files, for example. The leaves smartd in the file /etc/default/smartmontools activate. The configuration itself is done through /etc/smartd.conf . Fortunately, this file is filled with examples explained. You basically just need the appropriate line search. Next, remove the double cross that line and adjust as desired yet. Now you can start the service manually. On Ubuntu, it works like this: /etc/init.d/smartmontools start. This start command can vary from distribution to distribution.
