Metrics
Prerequisites
In order to gather metrics, make sure you have a simulation that is currently running. If that is not the case, please refer to the section on starting your simulation. You will also need your cluster key for accessing the metrics of remote simulations.
While your simulation is running on a cluster if you have set metrics_enabled to true in your configuration, our infrastructure will collect metrics from all the running servers populating a Prometheus database. The metrics_enable configuration can be found in the
runtime_config.toml file in the example configuration. Please see the platform documentation for more details.You can either connect directly to this database which will be running on your gateway server on port 9090, or alternatively the Hadean CLI includes a function to allow you to retrieve a text file including the Prometheus format metrics using the following command.
