Server Agent for ARM Processor (Embedded Processors)

[mattta...@gmail.com]

Currently I am getting this error:

I can see from here that I don't have a libsigar-arm-linux.so where can I get this from?

Hi,

This question should be addressed to Hyperic SIGAR developers. ServerAgent use their library to contact OS for measurings.

If you have enough linux user skills you can try building sigar on arm from sources and renaming resulting SO to desired.

Okay Thanks

[mattta...@gmail.com]

Here it is if anyone else needs it.

Thanks

The reason I post this is because there may be someone like me trying to get PerfMon working on a target board that has and embedded ARM processor

[Andrey Pohilko]

Please, share the way you achieved your goal. Did you just built sigar from sources on ARM board?

Yes...sorry for the late reply I just did a build ANT on the target board then placed the file in the lib for server Agent.

Building SIGAR

The native library, Java JNI bindings and Java classes are built using the same build system which has the following requirements:

• JDK 1.4 or higher
• Ant 1.6.5 or higher
• Perl 5.6.1 or higher
• C compiler

Perl is required to generate much of the JNI code as well as many of the Java classes. The ant build system uses a modified version of
cpptasks which works on all platforms supported by SIGAR. The native library can be used by the following languages:

• C/C++
• Java (sigar.jar auto-loads the native library)
• Perl (requires bindings/perl build)
• .NET C# (requires bindings/csharp build)
• Ruby (requires bindings/ruby build)
• Python (requires bindings/python build)
• PHP (requires bindings/php build)
• Erlang (requires bindings/erl build)

Note The native library includes Java_org_hyperic_sigar_* functions, however there are no JRE dependencies for pure C/C++ applications using SIGAR. The Java JNI interface uses runtime linking and a function-pointer interface which allows us to combine both the sigar_ C API and JNI implementations into a single library. If this is not desirable, it would be trivial to have your own project build system simply compile src/*.c and src/os/$osname/*.c, then link the object files directly into your library or application.

Example build:

% tar -zxf hyperic-sigar-1.6.4-src.tar.gz   % cd hyperic-sigar-1.6.4-src/bindings/java % ant

Results in:

% ls -1 sigar-bin/lib libsigar-universal-macosx.dylib sigar.jar

Test using:

% java -jar sigar-bin/lib/sigar.jar test
