I'm looking for a library that will provide this type of information:
RAM
Swap space
Number of CPUs
speed (CPU MHz)
Number of cores
Chip type
Ultimately I'll be calling into it from Java, but a C library would be fine, which I can wrap with JNI.
Platforms of interest include, but not limited to, AIX, HP-UX, Solaris, Windows.
Thanks!
Are you looking to query these systems remotely? If so, your best bet will probably be to use an SNMP library.
You may want to check out the following documentation site: http://en.wikipedia.org/wiki/Hardware_abstraction_layer
Also check out the Open Audit computer auditing and inventory tracking system http://www.open-audit.org source code and there script for auditing linux machines for examples of querying a hal database.
Like you I was looking for a cross platform system info library and found this:

I didn't test it yet but it might suit your needs.
good luck !
You can take a look at Sigar which supports the metrics and platforms that you want and has both C and Java APIs. It is GPL, which may or may not suit your needs.
