+
+This exporter supports sending metrics to BMC Helix Operation Management.
+
+## Getting Started
+
+The following settings are **required**:
+
+- `endpoint`: is the URL of your BMC Helix environment, at **onbmc.com** (e.g., `https://company.onbmc.com`).
+- `api_key`: API key to authenticate the exporter. Connect to BMC Helix Operations Management, go to the Administration > Repository page, and click on the Copy API Key button to get your API Key.
+
+Example:
+
+```yaml
+exporters:
+  bmchelix/helix1:
+    endpoint: https://company.onbmc.com
+    api_key: <api-key>
+```
+
+### Optional Settings
+
+The following settings can be **optionally configured**:
+
+- `timeout`: (default = `10s`) Timeout for requests made to the BMC Helix.
+- `retry_on_failure` [details here](https://github.com/open-telemetry/opentelemetry-collector/tree/main/exporter/exporterhelper#configuration)
+  - `enabled` (default = true)
+  - `initial_interval` (default = 5s) Time to wait after the first failure before retrying; ignored if `enabled` is false.
+  - `max_interval` (default = 30s) The upper bound on backoff; ignored if `enabled` is false.
+  - `max_elapsed_time` (default = 300s) The maximum amount of time spent trying to send a batch; ignored if `enabled` is false. If set to 0, the retries are never stopped.
+- `resource_to_telemetry_conversion`: [details here](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/pkg/resourcetotelemetry#configuration)
+  - `enabled` (default = true): If enabled is true, all the resource attributes will be converted to metric labels by default.
+
+Example:
+
+```yaml
+exporters:
+  bmchelix/helix2:
+    endpoint: https://company.onbmc.com
+    api_key: <api-key>
+    timeout: 20s
+    retry_on_failure:
+      enabled: true
+      initial_interval: 5s
+      max_interval: 1m
+      max_elapsed_time: 8m
+    resource_to_telemetry_conversion:
+      enabled: true
+```
+
+### Resource to Telemetry Conversion
+
+To ensure resource attributes (e.g., `host.name`) are available for all metrics, keep `resource_to_telemetry_conversion` enabled by default. Disabling it will remove resource attributes from metrics unless explicitly configured.
+
+---
+
+## Setting Required Attributes for Metrics
+
+To ensure metrics are correctly populated in BMC Helix, the following attributes must be set:  
+
+- `entityName`: Unique identifier for the entity. Used as display name if `instanceName` is missing.
+- `entityTypeId`: Type identifier for the entity.
+- `instanceName`: Display name of the entity.
+
+> **Note:** If `entityName` or `entityTypeId` is missing, the metric will not be populated.
+
+### Transformer Example for Hardware Metrics
+
+You can use the following OpenTelemetry Transformation Language (OTTL) configuration to map these attributes dynamically:
+
+```yaml
+  transform/hw_to_helix:
+   # Apply transformations to all metrics
+    metric_statements:
+
+      - context: datapoint
+        statements:
+          # Create a new attribute 'entityName' with the value of 'id'
+          - set(attributes["entityName"], attributes["id"]) where attributes["id"] != nil
+          # Create a new attribute 'instanceName' with the value of 'name'
+          - set(attributes["instanceName"], attributes["name"]) where attributes["name"] != nil
+
+      - context: datapoint
+        conditions:
+          - IsMatch(metric.name, ".*\\.agent\\..*")
+        statements:
+          - set(attributes["entityName"], attributes["host.id"]) where attributes["host.id"] != nil
+          - set(attributes["instanceName"], attributes["service.name"]) where attributes["service.name"] != nil
+          - set(attributes["entityTypeId"], "agent")
+
+      - context: datapoint
+        statements:
+          # Mapping entityTypeId based on metric names and attributes
+          - set(attributes["entityTypeId"], "connector") where IsMatch(metric.name, ".*\\.connector\\..*")
+          - set(attributes["entityTypeId"], "host") where IsMatch(metric.name, ".*\\.host\\..*") or attributes["hw.type"] == "host"
+          - set(attributes["entityTypeId"], "battery") where IsMatch(metric.name, "hw\\.battery\\..*") or attributes["hw.type"] == "battery"
+          - set(attributes["entityTypeId"], "blade") where IsMatch(metric.name, "hw\\.blade\\..*") or attributes["hw.type"] == "blade"
+          - set(attributes["entityTypeId"], "cpu") where IsMatch(metric.name, "hw\\.cpu\\..*") or attributes["hw.type"] == "cpu"
+          - set(attributes["entityTypeId"], "disk_controller") where IsMatch(metric.name, "hw\\.disk_controller\\..*") or attributes["hw.type"] == "disk_controller"
+          - set(attributes["entityTypeId"], "enclosure") where IsMatch(metric.name, "hw\\.enclosure\\..*") or attributes["hw.type"] == "enclosure"
+          - set(attributes["entityTypeId"], "fan") where IsMatch(metric.name, "hw\\.fan\\..*") or attributes["hw.type"] == "fan"
+          - set(attributes["entityTypeId"], "gpu") where IsMatch(metric.name, "hw\\.gpu\\..*") or attributes["hw.type"] == "gpu"
+          - set(attributes["entityTypeId"], "led") where IsMatch(metric.name, "hw\\.led\\..*") or attributes["hw.type"] == "led"
+          - set(attributes["entityTypeId"], "logical_disk") where IsMatch(metric.name, "hw\\.logical_disk\\..*") or attributes["hw.type"] == "logical_disk"
+          - set(attributes["entityTypeId"], "lun") where IsMatch(metric.name, "hw\\.lun\\..*") or attributes["hw.type"] == "lun"
+          - set(attributes["entityTypeId"], "memory") where IsMatch(metric.name, "hw\\.memory\\..*") or attributes["hw.type"] == "memory"
+          - set(attributes["entityTypeId"], "network") where IsMatch(metric.name, "hw\\.network\\..*") or attributes["hw.type"] == "network"
+          - set(attributes["entityTypeId"], "other_device") where IsMatch(metric.name, "hw\\.other_device\\..*") or attributes["hw.type"] == "other_device"
+          - set(attributes["entityTypeId"], "physical_disk") where IsMatch(metric.name, "hw\\.physical_disk\\..*") or attributes["hw.type"] == "physical_disk"
+          - set(attributes["entityTypeId"], "power_supply") where IsMatch(metric.name, "hw\\.power_supply\\..*") or attributes["hw.type"] == "power_supply"
+          - set(attributes["entityTypeId"], "robotics") where IsMatch(metric.name, "hw\\.robotics\\..*") or attributes["hw.type"] == "robotics"
+          - set(attributes["entityTypeId"], "tape_drive") where IsMatch(metric.name, "hw\\.tape_drive\\..*") or attributes["hw.type"] == "tape_drive"
+          - set(attributes["entityTypeId"], "temperature") where IsMatch(metric.name, "hw\\.temperature.*") or attributes["hw.type"] == "temperature"
+          - set(attributes["entityTypeId"], "vm") where IsMatch(metric.name, "hw\\.vm\\..*") or attributes["hw.type"] == "vm"
+          - set(attributes["entityTypeId"], "voltage") where IsMatch(metric.name, "hw\\.voltage.*") or attributes["hw.type"] == "voltage"
+```
+
+This transformer dynamically sets the attributes required for BMC Helix based on metric names and resource attributes.
