The telemetry role allows users to set up iDRAC telemetry support and visualizations.

| Name | Default, accepted values | Required? | Purpose |
|---|---|---|---|
| idrac_telemetry_support | true, false | Required | Enables iDRAC telemetry support and visualizations. |
| slurm_telemetry_support | true, false | Required | Enables slurm telemetry support and visualizations. |
| timescaledb_name | telemetry_metrics | Optional | Postgres DB name with timescale extension is used for storing iDRAC and slurm telemetry metrics. |
| mysqldb_name | idrac_telemetrysource_services_db | Optional | MySQL DB name used to store IPs and credentials of iDRACs having datacenter license |
| timezone | GMT, EST, CET, MST, CST6CDT, PST8PDT | Optional | This is the timezone that will be set during provisioning of OS. Accepted values are listed in telemetry/common/files/timezone.txt |
| timescaledb_user | Required | Username used for to authenticate to timescale db. The username must not contain -,, ',". The Length of the username should be at least 2 characters. | |
| timescaledb_password | Required | Password used for to authenticate to timescale db. The username must not contain -,, ',". The Length of the username should be at least 2 characters. | |
| mysqldb_user | Required | Username used for to authenticate to mysql db. The username must not contain -,, ',". The Length of the username should be at least 2 characters. | |

| mysqldb_root_password | Required | Root password used for to authenticate to mysql db. The username must not contain -,, ',". The Length of the username should be at least 2 characters. | |
| idrac_username | Optional | The username for idrac. The username must not contain -,, ',". Required only if idrac_telemetry_support is true. | |
| idrac_password | Optional | The password for idrac. The username must not contain -,, ',". Required only if idrac_telemetry_support is true. | |
| grafana_username | Required | The username for grafana UI. The length of username should be at least 5. The username must not contain -,, ',". | |

Once control_plane.yml and omnia.yml are executed, run the following commands from omnia/telemetry: :
ansible-playbook telemetry.yml -i inventoryNote
The passed inventory should have 3 groups: idrac, manager, compute.
After initiation, new nodes can be added to telemetry by running the following commands from omnia/telemetry: :
ansible-playbook add_idrac_node.yml -i inventoryNote
* The passed inventory should have an idrac group. * telemetry_config.yml is encrypted upon executing telemetry.yml. View and edit instructions are provided in the Troubleshooting Guide * If idrac_telemetry is true while executing telemetry.yml, or while running add_idrac_node.yml, if the inventory passed does not contain an idrac group, idrac telemetry will run on IP’s present under /opt/omnia/provisioned_idrac_inventory of control plane.
