Hyperic SIGAR 1.4

Hyperic SIGAR (System Information Gatherer and Reporter) is a cross-platform, cross-language library and command-line tool for accessing operating system and hardware level information in Java, Perl and .NET.
Hyperic developed SIGAR to overcome the lack of portable access to low-level hardware and operating system metrics found in the Java platform. Its now a key component of the Hyperic HQ management platform since it provides HQ with visibility into things that are otherwise impossible to get to through the standard Java API.
Over the last four years of development, weve enhanced SIGAR to support multiple language bindings and operate on more than 10 OS/hardware combinations.
We think other applications would benefit from the type of information SIGAR provides. We also want to create and foster a community of users who will help us push this technology forward and incorporate it into both open source and commercial applications. So we decided to make this technology open source to give others the ability to enhance their applications.
Main features:
- System memory statistics - total, free, shared
- CPU statistics - load averages, user cpu, system cpu
- Process level statistics - process arguments, memory consumption, cpu consumption, credential info, state, environment, open file descriptors
- File system level statistics - local and remote mounted file systems (NTFS, ext, SMB, NFS, etc), capacity, utilization
- Network interface level statistics - all available network interfaces detected and monitored for bytes received/transmitted, packets received/transmitted, collisions, errors, dropped packets
Enhancements:
- Improved performance and efficiency.
- A bug with User Mode Linux VMs where SIGAR acquired incorrect CPU info has been fixed.
