SANtools® S.M.A.R.T. Disk Monitor (SMARTMon-UX)158

(.. truncated here)
Current temperature +/- 3 degrees C: 41
Reference temperature +/- 3 degrees C: 68
The current temperature is 41C, and the shutdown is 68C. You can see that this disk drive can run much hotter before
there is need for concern.
Notes:
The temperature for SCSI, SAS, and fibre channel devices is standardized, but optional.
You can also obtain device temperature via the log page viewer .
1.46 Threshold Monitoring
In order to monitor thresholds, invoke your user-defined scripts, and email alerts and log file entries, you must invoke
the program with the -W option and supply SMARTMon-UX with the name of your configuration file.
Usage
smartmon-ux -Wfilename
Example
smartmon-ux -WDiskRWActivityRecorder.cfg
For details on the syntax and creation of the script, refer to the Threshold Configuration portion of this manual.
Note: Do not put a space between the -W and the filename!
1.47 Threshold Configuration
Threshold monitoring, introduced in release 1.15, is a powerful method for defining exactly what you want to monitor,
how often you want to look at it, and what you want to happen should it occur.
What can you do with log page threshold monitoring?
· Provide an alert if you have an A/C failure by monitoring drive temperature.
· Watch for unrecovered read or write errors.
· Watch for unrecovered write errors which might indicate data corruption.
· Automatically alert you when your tape drive indicates it needs to have the heads cleaned.
· Tell you if you have unrecovered read or write errors from your tape drive when creating a backup or performing a
recovery.
· Interface storage device and status information for your JBOD into enterprise-level SRM packages.
By optionally configuring an event script, you can launch a procedure of your choice if you have such a situation.
For example, with relatively little effort, you could poll megabytes read of a disk on 5 minute intervals, append the
information into a flat file, and import it into a spread sheet to graph your throughput over time. If you have a disk that
is in a SAN that is shared among multiple systems, there is NO other way to determine this information.
In order to utilize this feature, you must create a configuration file and launch SMARTMon-UX with the -W option
(Note - no space between the W and the filename) and pass it the name of the configuration file. The configuration
file is managed by launching smartmon-ux in the interactive mode with the -K option. You then choose configuration
commands in order to manipulate the file. This configuration file is in ASCII text, and you are free to edit it manually if
you desire. Once you familiarize yourself with the record layout, you might find it much more efficient to edit it
manually. Note that while the record layout is slightly different for UNIX and Windows-family operating systems, it is
consistent across all UNIX and LINUX versions.
Configuration Commands
When you launch the program with the -K option (smartmon-ux -K), it discovers all peripherals and returns with a list
of options. The program will not launch into the background, and it will not monitor hardware. The purpose of this
