Collecting metrics by using BMC Helix Monitor Agent for OTel

The BMC Helix Monitor Agent for OTel streamlines data ingestion with a unified approach. It gathers metrics from various sources that export telemetry data in the OpenTelemetry Protocol (OTLP) format and forwards them to the backend.

OpenTelemetry is an open-source, vendor-neutral observability framework designed to instrument, generate, collect, and export telemetry data.

By adopting this standardized approach, the agent simplifies monitoring, improves visibility, and enables seamless integration of custom telemetry sources while optimizing data processing workflows.

Capabilities

• Seamless deployment and scalability: The BMC Helix Monitor Agent for OTel can be easily deployed within existing infrastructure, supporting horizontal scaling to accommodate growing telemetry needs. 
• Centralized configuration and governance: Organizations can centrally configure and enforce telemetry data collection rules across all monitored environments with policy management. 
• Flexible data collection mechanisms: BMC Helix Monitor Agent for OTel supports both push and pull models, allowing independent receivers to push metrics directly and enabling pluggable Knowledge Modules (KMs) to pull metrics as needed. 
• Real-time, Low-Latency Telemetry: It ensures high-frequency data collection with near-instantaneous processing, enabling faster decision-making in dynamic environments. 
• High extensibility: Its modular architecture allows seamless integration with third-party monitoring tools, cloud-based observability solutions, and custom-built monitoring stacks. 
• Enhanced interoperability: BMC Helix Monitor Agent for OTel works effortlessly with existing telemetry solutions, including Prometheus, allowing you to leverage your preferred monitoring ecosystem without vendor lock-in. 
• Reduced operational overhead: BMC Helix Monitor Agent for OTel simplifies monitoring and reduces management complexity by unifying multiple observability signals into a single framework.

Architecture

The BMC Helix Monitor Agent for OTel is a vendor-agnostic telemetry agent that efficiently collects, processes, and exports performance metrics.

Key components of BMC Helix Monitor Agent for OTel

• Receiver: Handles metric ingestion via pull mechanisms.
• Processor: Transforms, aggregates, and filters collected data.
• Exporter: Sends the processed metrics to BMC Helix Operations Management for visualization, analysis, and alerting.

Metric collection and data flow

• Data ingestion 
  • The Host pushes performance metrics to the BMC Helix Monitor Agent for OTel by using OTLP.
  • The agent also supports pluggable Knowledge Modules that pull additional metrics.
• Data processing within BMC Helix Monitor Agent for OTel
  • Receiver: Collects incoming OpenTelemetry (OTEL) metrics from the Host or pluggable KMs.
  • Processor: Maps metadata and processes the data by aggregating, filtering, or transforming it.
  • Exporter: Prepares and sends the processed monitoring entities to BMC Helix Operations Management.
• Data streaming and policy configuration
  • The BMC Helix Monitor Agent for OTel streams processed data to BMC Helix Operations Management, ensuring real-time monitoring insights.
  • Policies configured in BMC Helix Operations Management dynamically control data collection, filtering, and processing within the agent.

This architecture ensures efficient and scalable telemetry data collection, reducing the operational complexity of managing multiple monitoring agents.

To deploy the package

You can deploy a package either manually or silently. To deploy the package manually, use the option available on the UI. To deploy the package silently, either download it and run the silent installation commands or copy and run the install script.

Deploying the package manually

1. Click Configuration and select Agents (in BMC Helix Operations Management) or Managed Devices (in TrueSight Operations Management).
2. Perform one of the following actions:
   • To deploy and install packages on a single PATROL Agent, click the action menu.

   • To deploy and install packages on multiple PATROL Agents, select the devices by holding the Shift key, selecting them, and then clicking the action menu from the column heading.

     For deploying a package on multiple PATROL Agents or when you upgrade PATROL Agents, only the instance or service names that contain the word "PatrolAgent" are supported. The instance or service names are not case-sensitive.

3. Click Deploy and Install Packages and select your package name.
   View the current installation status by hovering your mouse over the icon in the Deploy Status column.
   If a package deployment fails in validation, an error message is displayed. Any remaining compatible packages are deployed and installed on the PATROL Agent.

Deploying the package silently

1. If you have not downloaded the package, download it by following these steps:
   1. Click Administration and select Repository.
