### Considerations
## Considerations
- Plug-in **paths** is set by default to `$EAR_INSTALL_PATH/lib/plugins`.
- Default **power model** library is specified in `ear.conf` (*energy_model* option). By default EAR includes a `basic_model.so` and `avx512_model.so` plug-ins.
- The **node energy readings** library is specified at `ear.conf` in the *energy_plugin* option for each tag. Several plug-ins are included: `energy_nm.so` (uses Intel NodeManager IPMI commands), `energy_rapl.so` (uses a node energy estimation based on DRAM and PACKAGE energy provided by RAPL), `energy_sd650.so` (uses the high frequency IPMI hardware included in Lenovo SD650 systems) and the `energy_inm_power_freeipmi.so`, which uses the Intel Node Manager power reading commands and requires the freeipmi library.
- **Power policies** included in EAR are: `monitoring.so`, `min_energy.so`, `min_time.so`, `min_energy_no_models.so` and `min_time_no_models.so`. The list of policies installed is automatically detected by the EAR plug-in. However, only policies included in `ear.conf` can be used.
- The **tracing** is an optional functionality. It is included to provide additional information or to generate runtime information.
- **Report** plug-ins include different options to report EAR data from the different components. By default it is included the eard, eardbd, csv_ts, mysql/psql (depending on the installation). Plug-ins to be loaded by default can be specified on the `ear.conf`.
- **Report** plug-ins include different options to report EAR data from the different components. By default it is included the eard, eardbd, csv_ts, mysql/psql (depending on the installation). Plug-ins to be loaded by default can be specified on the `ear.conf`. For more information, check the [report section](Report)
> **Note** SLURM Plugin does not fit in this philosophy, it is a core component of EAR and can not be replaced by any third party development.
