InfiniBand and ServiceNow Integration

Input and output integration overview

The InfiniBand Telegraf plugin collects performance metrics from all InfiniBand devices installed on a Linux system, providing essential insights for monitoring network performance and reliability.

This output plugin streams metrics from Telegraf directly to a ServiceNow MID Server via HTTP, leveraging the nowmetric serializer for efficient integration with ServiceNow’s Operational Intelligence and Event Management.

Integration details

InfiniBand

This plugin gathers statistics for all InfiniBand devices and ports on the system. InfiniBand is a high-speed networking technology commonly used in high-performance computing and enterprise data centers. The plugin retrieves various performance counters from the system’s InfiniBand devices located in /sys/class/infiniband/<dev>/port/<port>/counters/. The metrics depend on the specific InfiniBand hardware and include various packet and error statistics that are essential for monitoring network health and performance. By utilizing this plugin, users can gain insights into the operational status of their InfiniBand networks, helping to identify potential issues and optimize performance.

ServiceNow

Telegraf can be used to send metric data directly to a ServiceNow MID Server REST endpoint. Metrics are formatted either using ServiceNow’s Operational Intelligence (OI) format or JSONv2 format, enabling seamless integration with ServiceNow’s Event Management and Operational Intelligence platforms. The serializer batches metrics efficiently, reducing network overhead by minimizing the number of HTTP POST requests. This integration allows users to quickly leverage metrics in ServiceNow for enhanced observability, proactive incident management, and performance monitoring, with ServiceNow’s operational intelligence capabilities.

Input and output integration examples

InfiniBand

1. Performance Monitoring in High-Performance Computing (HPC): Monitor the performance metrics of InfiniBand interconnects in a high-performance computing cluster. By analyzing metrics such as packet errors and throughput, system administrators can ensure optimal operation and quickly identify any performance degradation. This setup enhances the reliability of computational tasks by allowing timely interventions based on accurate monitoring data.

2. Network Health Audits: Perform routine health checks of InfiniBand networks. The detailed metrics gathered, such as excessive buffer overruns and link integrity errors, provide valuable insights for network audits. By establishing baseline performance and watching for anomalies, IT professionals can ensure the stability and performance of critical infrastructures.

3. Integration with Alerting Systems: Set up the InfiniBand plugin to work in conjunction with alerting systems to trigger notifications based on performance thresholds. For instance, if the number of link errors exceeds a predefined limit, an alert can be sent to the network operations team. This proactive approach ensures that potential issues are addressed before they impact business operations.

4. Data Visualization Dashboards: Feed InfiniBand metrics to a visualization tool to create dashboards that display the real-time performance of the network. This can help stakeholders visualize critical data such as packet transmission rates and errors, facilitating better decision-making regarding network management and capacity planning.

ServiceNow

1. Proactive Incident Management: Utilize the Telegraf and ServiceNow integration to stream infrastructure and application metrics in real-time to ServiceNow Event Management. Automatically trigger incidents or remediation workflows based on thresholds, significantly reducing incident detection and response times.

2. End-to-End Application Monitoring: Deploy Telegraf agents across multiple layers of an application stack, sending performance metrics directly into ServiceNow. Leveraging ServiceNow’s Operational Intelligence, teams can correlate metrics across components, quickly identifying performance bottlenecks.

3. Dynamic CI Performance Tracking: Integrate Telegraf metrics with ServiceNow’s CMDB by using this plugin to push performance data, allowing automatic updates of Configuration Item (CI) health states based on live metrics. This ensures an accurate and current state of infrastructure health in ServiceNow.

4. Cloud Resource Optimization: Collect metrics from hybrid and multi-cloud infrastructures using Telegraf, streaming directly to ServiceNow. Leverage these metrics for real-time analytics, predictive capacity planning, and resource optimization, enabling proactive management and reduced operational costs.
