Overseer is a set of tools simplifying access to real-time measurement of low-level information such as Hardware Performance Counters (HPCs), IPMI sensors, and Java VM internal events. Overseer supports functionalities like HPC-management, process/thread affinity settings, RDTSC timers, child-processes tracing, power-consumption and temperature monitoring, etc. Both the C/C++ and Java languages are supported.
Based on libpfm4 and Linux kernels (2.6.31+), Overseer does not require specific patches or additional modules, thus offering a better solution for distributed and dynamic configurations not demanding administrator modifications to the underlying system.
Overseer requires the following development tools to be installed and configured on the targeted systems:
- libpfm http://perfmon2.sourceforge.net/
- hwloc http://www.open-mpi.org/projects/hwloc/
- freeipmi http://www.gnu.org/software/freeipmi/
For Fedora 22 and later versions:
sudo dnf install -y libpfm hwloc freeipmi libpfm-devel hwloc-devel freeipmi-devel
make
sudo make installRuntime libraries are installed to /usr/local/bin by default. Edit makefiles if your Linux distribution doesn't follow this standard.
To access Overseer functionalities from Java, include the overseer.jar file that is available in the /src/java/ directory.
Also don't forget about Shared Library Management(http://www.cyberciti.biz/tips/linux-shared-library-management.html) and register your dynamic libraries in /etc/ld.so.conf or use LD_LIBRARY_PATH environment variable.
