Java Code For Pulling Hard Drive Information From Linux

I've recently been tasked with developing a program to monitor a bunch of hard drive information (serial, maker, type, etc) from multiple hard drives. In my initial research I found that this was pretty easy to do using some C# code and created a test program that way. Unfortunately, I'm required to use a linux OS which means c# is off the table.

I was curious if anyone knows, or could point me in the right direction of developing an app in Java/C/C++ that would achieve the same effect. I do know that if you use Java you have to use the JNI and you're using C/C++ at that point regardless.

Thanks.

Depending on the exact information you need there might be no need to use JNI.

Linux make a lot of information about the hardware available in the sysfs and procfs virtual filesystems. For instance, you can find the harddisk model for the fist disk in /sys/block/sda/device/model, which you should be able to read in Java just like any other file.

Additionally you could look at the output of fdisk -l /dev/sda' andhdparm -I /dev/sdawhich both provide quite a bit of information. You can call these usingRuntime.exec()` and parse the output.

I'm not aware of any Java libraries making your life easier, but if you want to implement an OS independent solution supporting different OSes you should have a look at java.lang.Runtime which enables you to execute external processes. You could maintain a map for each OS defining the (CLI) commands for retrieving the required information. It may be easier than implementing a bunch of native calls using JNI:

Process p = Runtime.getRuntime().exec("df -h");
p.waitFor();

InputStream is = p.getInputStream();

/* work with command line output... */

I know it's not a perfect solution, but you may want to have a look at it.
