Getting System Information of server machine.... disk info. etc.

Hi

I have a JSP utility which runs on tomcat and also has a backend Java process which utilises a MySQL DB. Now I am building some pretty large tables of data. And I want to be able to check via the web server the space available on disk, I'd also like to check other things like memory usage and system start time etc.

Now the memory usage one I can get from the system class (along with OS etc. ) however I cannot find a way to get disk info.

Any help would be grrreeaaattt

cheers

There is no standard way to get it. On windows you can use something like this:
Process p = Runtime.getRuntime().exec("cmd /c dir c:");
BufferedReader br = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
String freeSpace = "";
while ((line = br.readLine()) != null) {
if (line.indexOf("bytes free") > -1) {
int start = line.indexOf("dir(s)") + 7;
int end = line.indexOf("bytes free", start);
freeSpace = line.substring(start, end).trim();
break;
}
}
System.out.println("Free space: " + freeSpace);

That is a nice way of getting the info. however theres a few flaws in that this will only work on windows and what if there are multiple hard disks or the disk is not c: it is g: etc.
