This document describes the options when configuring Entropy. All the options are defined in the file config/entropy.properties and are loaded at startup.
This section describes the parameters to connect Entropy to the gmeta daemon .
| Property | Description | Default value |
| gmetad.host | The IP or hostname of the gmeta daemon | localhost |
| gmetad.port | The port of the gmeta daemon | 8651 |
This section describes the parameters to tune the decision and the plan module.
| Property | Description | Default value |
| dynamicConsolidation.vmpp.solvingTime | The solving time for the decision module in seconds. With a short solving time, the system is more reactive but may miss improved solutions or even a single solution if the problem is hard. | 60 |
| dynamicConsolidation.vmrp.solvingTime | The solving time for the plan module in seconds. The explanation are the same than above | 60 |
| dynamicConsolidation.simplify.activate | If the virtual machine are CPU intensive, then they can be considered as actives when they require their own CPU (e.g when a big computation is performed). Otherwise, they are inactive and their current consumption does not require a dedicated CPU. If this property is set to true, then the current requirement of each virtual machine is mapped following this model (it simplify the problem). | true |
| dynamicConsolidation.simplify.threshold | If the simplification is activated, then this property define the activity threshold. If the CPU consumption of a virtual machine is below this value, then the virtual machine is considered as inactive. Otherwise, it is considered inactive | 500 |
