Google Cloud PubSub and VictoriaMetrics Integration

Input and output integration overview

This plugin ingests metrics from Google Cloud PubSub, allowing for real-time data processing and integration into monitoring setups.

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

Google Cloud PubSub

The Google Cloud PubSub input plugin is designed to ingest metrics from Google Cloud PubSub, a messaging service that facilitates real-time communication between different systems. It allows users to create and process metrics by pulling messages from a specified subscription in a Google Cloud Project. One of the critical features of this plugin is its ability to operate as a service input, actively listening for incoming messages rather than merely polling for metrics at set intervals. Through various configuration options, users can customize the behavior of message ingestion, such as handling credentials, managing message sizes, and tuning the acknowledgment settings to ensure that messages are only acknowledged after successful processing. By leveraging the strengths of Google PubSub, this plugin integrates seamlessly with cloud-native architectures, enabling users to build robust and scalable applications that can react to events in real-time.

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

Google Cloud PubSub

[[inputs.cloud_pubsub]]
  project = "my-project"
  subscription = "my-subscription"
  data_format = "influx"
  # credentials_file = "path/to/my/creds.json"
  # retry_delay_seconds = 5
  # max_message_len = 1000000
  # max_undelivered_messages = 1000
  # max_extension = 0
  # max_outstanding_messages = 0
  # max_outstanding_bytes = 0
  # max_receiver_go_routines = 0
  # base64_data = false
  # content_encoding = "identity"
  # max_decompression_size = "500MB"

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

Google Cloud PubSub

1. Real-Time Analytics for IoT Devices: Utilize the Google Cloud PubSub plugin to aggregate metrics from IoT devices scattered across various locations. By streaming data from devices to Google PubSub and using this plugin to ingest metrics, organizations can create a centralized dashboard for real-time monitoring and alerting. This setup allows for immediate insights into device performance, facilitating proactive maintenance and operational efficiency.

2. Dynamic Log Processing and Monitoring: Ingest logs from numerous sources via Google Cloud PubSub into a Telegraf pipeline, utilizing the plugin to parse and analyze log messages. This can help teams quickly identify anomalies or patterns in logs and streamline the process of troubleshooting issues across distributed systems. By consolidating log data, organizations can enhance their observability and response capabilities.

3. Event-Driven Workflow Integrations: Use the Google Cloud PubSub plugin to connect various cloud functions or services. Each time a new message is pushed to a subscription, actions can be triggered in other parts of the cloud architecture, such as starting data processing jobs, notifications, or even updates to reports. This event-driven approach allows for a more reactive system architecture that can adapt to changing business needs.

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.
