overview
The Sigar API provides a portable interface for gathering system information such as:
- System memory, swap, cpu, load average, uptime, logins
- Per-process memory, cpu, credential info, state, arguments, environment, open files
- File system detection and metrics
- Network interface detection, configuration info and metrics
- TCP and UDP connection tables Network route table
This information is available in most operating systems, but each OS has their own way(s) providing it. SIGAR provides developers with API to access this information regardless of the underlying platform. one The core API is implemented in pure C with bindings currently implemented for Java, Perl, Ruby, Python, Erlang, PHP and C#. The following platforms are currently supported:
| Operating System | Arch | Versions | Binaries included |
|---|---|---|---|
| Linux | x86 | 2.2, 2.4, 2.6 kernels | yes |
| Linux | amd64 | 2.6 kernels | yes |
| Linux | ppc | 2.6 kernels | yes |
| Linux | ppc64 | 2.6 kernels | yes |
| Linux | ia64 | 2.6 kernels | yes |
| Linux | s390 | 2.6 kernels | no |
| Linux | s390x | 2.6 kernels | no |
| Windows | x86 | NT4.0 through Windows 10 | yes |

While SIGAR only depends on the Linux kernel version, the following distributions have been certified:
| Distribution | Versions |
|---|---|
| Red Hat | 6.2, 7.3, 8.0, 9.0 |
| RHEL | 3, 4, 5, 6 |
| CentOS | 3, 4, 5 |
| Fedora | 2, 3, 4, 5, 6, 7, 8, 9, 10 |
| SuSE | 8, 9, 10, 11 |
| Ubuntu | 6.06, 8.04, 8.10, 9.04 |
| Debian | 2.6, 3.0, 3.1, 3.2, 4.0, 5.0 |
| VMware ESX | 2.x, 3.0 |
| XenServer | 3.1, 3.2, 4.0, 4.1, 5.0 |
| Slackware | 10, 11 |
| Mandrake | 10 |
| Scientific Linux | 5 |
| Gentoo |
To test drive run the following command:
% java -jar sigar-bin/lib/sigar.jar
sigar> help
The shell and commands are implemented in Java, the source code is located in .bindings/java/src/org/hyperic/sigar/cmd/ Including implementations of well-known commands such as:
- df
- du
- free
- ifconfig
- iostat
- netstat
- ps
- route
- top
- ulimit
- uptime
- who
Perl, Ruby, Python, Erlang, PHP and C# interfaces are still a work in progress. To try the Perl examples:
% cd bindings/perl
% perl Makefile.PL && make
% perl -Mblib examples/ifconfig.pl
