HAProxy and VictoriaMetrics Integration

Input and output integration overview

This plugin gathers and reports statistics from HAProxy, a popular open-source load balancer and proxy server, to help in monitoring and optimizing its performance.

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

HAProxy

The HAProxy plugin for Telegraf enables users to gather statistics directly from a HAProxy server via its stats socket or HTTP statistics page. HAProxy is a widely employed software load balancer and proxy server that provides high availability and performance for TCP and HTTP applications. By integrating with HAProxy, this plugin allows users to monitor and analyze various performance metrics such as active server counts, request rates, response codes, and session statuses in real-time, facilitating better decision-making and proactive management of network resources. Key features include support for both HTTP and socket-based metrics collection, compatibility with basic authentication for secure access, and configurable options for metric field naming, allowing for customization tailored to user preferences.

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.

Configuration

HAProxy

[[inputs.haproxy]]
  ## List of stats endpoints. Metrics can be collected from both http and socket
  ## endpoints. Examples of valid endpoints:
  ##   - http://myhaproxy.com:1936/haproxy?stats
  ##   - https://myhaproxy.com:8000/stats
  ##   - socket:/run/haproxy/admin.sock
  ##   - /run/haproxy/*.sock
  ##   - tcp://127.0.0.1:1936
  ##
  ## Server addresses not starting with 'http://', 'https://', 'tcp://' will be
  ## treated as possible sockets. When specifying local socket, glob patterns are
  ## supported.
  servers = ["http://myhaproxy.com:1936/haproxy?stats"]

  ## By default, some of the fields are renamed from what haproxy calls them.
  ## Setting this option to true results in the plugin keeping the original
  ## field names.
  # keep_field_names = false

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

VictoriaMetrics

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

  ## VictoriaMetrics accepts InfluxDB line protocol directly
  database = "db_name"

  ## Optional authentication
  # username = "username"
  # password = "password"
  # skip_database_creation = true
  # exclude_retention_policy_tag = true
  # content_encoding = "gzip"

  ## Timeout for HTTP requests
  timeout = "5s"

  ## Optional TLS configuration
  # tls_ca = "/path/to/ca.pem"
  # tls_cert = "/path/to/cert.pem"
  # tls_key = "/path/to/key.pem"
  # insecure_skip_verify = false

Input and output integration examples

HAProxy

1. Dynamic Load Adjustment: Utilize the HAProxy plugin to monitor traffic patterns in real time, enabling automated adjustments to load balancing algorithms. By continuously gathering metrics on server loads and request rates, system administrators can dynamically allocate resources, ensuring that no single server becomes a bottleneck, thus enhancing overall application performance and availability.

2. Historical Performance Analytics: Integrate this plugin with a time series database to collect HAProxy metrics over time, allowing you to analyze historical performance and traffic trends. This can facilitate predictive analysis and planning for capacity, giving businesses insights into peak traffic times and helping to identify potential future resource needs.

3. Alerting on Anomalies: Implement alerting workflows that trigger when unusual patterns are detected in HAProxy metrics, such as sudden spikes in error rates or drops in request handling capacity. By leveraging this plugin, operations teams can receive timely notifications, allowing for swift intervention and minimizing the impact of potential downtime on end-users.

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.
