OpenStack and VictoriaMetrics Integration

Input and output integration overview

This plugin collects metrics from essential OpenStack services, facilitating the monitoring and management of cloud infrastructures.

This plugin enables Telegraf to efficiently write metrics directly into VictoriaMetrics using the InfluxDB line protocol, leveraging the performance and scalability features of VictoriaMetrics for large-scale time-series data.

Integration details

OpenStack

The OpenStack plugin allows users to collect performance metrics from various OpenStack services such as CINDER, GLANCE, HEAT, KEYSTONE, NEUTRON, and NOVA. It supports multiple OpenStack APIs to fetch critical metrics related to these services, enabling comprehensive monitoring and management of cloud resources. As organizations increasingly adopt OpenStack for their cloud infrastructure, this plugin plays a vital role in providing insights into resource usage, availability, and performance across the cloud environment. Configuration options allow for customized polling intervals and filtering unwanted tags to optimize performance and cardinals.

VictoriaMetrics

VictoriaMetrics supports direct ingestion of metrics in the InfluxDB line protocol, making this plugin ideal for efficient real-time metric storage and retrieval. The integration combines Telegraf’s extensive metric collection capabilities with VictoriaMetrics’ optimized storage and querying features, including compression, fast ingestion rates, and efficient disk utilization. Ideal for cloud-native and large-scale monitoring scenarios, this plugin offers simplicity, robust performance, and high reliability, enabling advanced operational insights and long-term storage solutions for large volumes of metrics.

  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## Options for tags received from Openstack
  # tag_prefix = "openstack_tag_"
  # tag_value = "true"

  ## Timestamp format for timestamp data received from Openstack.
  ## If false format is unix nanoseconds.
  # human_readable_timestamps = false

  ## Measure Openstack call duration
  # measure_openstack_requests = false

VictoriaMetrics

[[outputs.influxdb]]
  ## URL of the VictoriaMetrics write endpoint
  urls = ["http://localhost:8428"]

Input and output integration examples

OpenStack

1. Cross-Cloud Management: Leverage the OpenStack plugin to monitor and manage multiple OpenStack clouds from a single Telegraf instance. By aggregating metrics across different clouds, organizations can gain insights into resource utilization and optimize their cloud architecture for cost and performance.

2. Automated Scaling Based on Metrics: Integrate the metrics gathered from OpenStack into an automated scaling solution. For example, if the plugin detects that a specific service’s performance is degraded, it can trigger auto-scaling rules to launch additional instances, ensuring that system performance remains optimal under varying workloads.

3. Performance Monitoring Dashboard: Use data collected by the OpenStack Telegraf plugin to power real-time monitoring dashboards. This setup provides visualizations of key metrics from OpenStack services, enabling stakeholders to quickly identify trends, pinpoint issues, and make data-driven decisions in managing their cloud infrastructure.

4. Reporting and Analysis of Service Availability: By utilizing the metrics collected from various OpenStack services, teams can generate detailed reports on service availability and performance over time. This information can help identify recurring issues, improve service delivery, and make informed decisions regarding changes in infrastructure or service configuration.

VictoriaMetrics

1. Cloud-Native Application Monitoring: Stream metrics from microservices deployed on Kubernetes directly into VictoriaMetrics. By centralizing metrics, organizations can perform real-time monitoring, rapid anomaly detection, and seamless scalability across dynamically evolving cloud environments.

2. Scalable IoT Data Management: Use the plugin to ingest sensor data from IoT deployments into VictoriaMetrics. This approach facilitates real-time analytics, predictive maintenance, and efficient management of massive volumes of sensor data with minimal storage overhead.

3. Financial Systems Performance Tracking: Leverage VictoriaMetrics via this plugin to store and analyze metrics from financial systems, capturing latency, transaction volume, and error rates. Organizations can rapidly identify and resolve performance bottlenecks, ensuring high availability and regulatory compliance.

4. Cross-Environment Performance Dashboards: Integrate metrics from diverse infrastructure components—such as cloud instances, containers, and physical servers into VictoriaMetrics. Using visualization tools, teams can build comprehensive dashboards for end-to-end performance visibility, proactive troubleshooting, and infrastructure optimization.
