Google Cloud Storage and DuckDB Integration

Input and output integration overview

The Google Cloud Storage plugin collects metrics from specified Google Cloud Storage buckets, providing insight into storage usage and performance.

This plugin enables Telegraf to write structured metrics into DuckDB using SQLite-compatible SQL connections, supporting lightweight local analytics and offline metric analysis.

Integration details

Google Cloud Storage

The Google Cloud Storage Telegraf plugin enables the collection of metrics from specified Google Cloud Storage buckets. As organizations increasingly rely on cloud storage solutions for their data management, the ability to monitor the performance and utilization of these resources becomes essential. This plugin is particularly useful for tracking how storage is used, understanding data patterns, and ensuring operational efficiency. By integrating with Google Cloud Storage APIs, it allows users to gather insights from their cloud environments, feeding metrics directly into monitoring systems for further analysis. The plugin supports various configuration options, enabling users to customize the data collection process based on their specific needs.

DuckDB

Use the Telegraf SQL plugin to write metrics into a local DuckDB database. DuckDB is an in-process OLAP database designed for efficient analytical queries on columnar data. Although it does not provide a traditional client-server interface, DuckDB can be accessed via SQLite-compatible drivers in embedded mode. This allows Telegraf to store time series metrics in DuckDB using SQL, enabling powerful analytics workflows using familiar SQL syntax, Jupyter notebooks, or integration with data science tools like Python and R. DuckDB’s columnar storage and vectorized execution make it ideal for compact and high-performance metric archives.

Configuration

Google Cloud Storage

[[inputs.google_cloud_storage]]
  bucket = "my-bucket"
  # key_prefix = "my-bucket"
  offset_key = "offset_key"
  objects_per_iteration = 10
  data_format = "influx"
  # credentials_file = "path/to/my/creds.json"

DuckDB

[[outputs.sql]]
  ## Use the SQLite driver to connect to DuckDB via Go's database/sql
  driver = "sqlite3"

  ## DSN should point to the DuckDB database file
  dsn = "file:/var/lib/telegraf/metrics.duckdb"

  ## SQL INSERT statement with placeholders for metrics
  table_template = "INSERT INTO metrics (timestamp, name, value, tags) VALUES (?, ?, ?, ?)"

  ## Optional: manage connection pooling
  # max_open_connections = 1
  # max_idle_connections = 1
  # conn_max_lifetime = "0s"

  ## DuckDB does not require TLS or authentication by default

Input and output integration examples

Google Cloud Storage

1. Automated Backup Monitoring: Utilize the Google Cloud Storage plugin to regularly monitor the status of backup files stored in a Cloud Storage bucket. By configuring the plugin to track file metrics, organizations can automate alerts if backup sizes deviate from expected patterns, ensuring that data protection processes are functioning properly and any anomalies are promptly addressed.

2. Cost Optimization Insights: Integrate this plugin into a cost management tool to analyze the usage patterns of Cloud Storage. By collecting metrics on file sizes and access frequencies, teams can optimize their storage solutions and make informed decisions about data retention policies, potentially reducing unnecessary storage costs and improving resource allocation.

3. Compliance and Auditing: Use the plugin to generate metrics that aid in compliance verification for data stored in Google Cloud Storage. By providing detailed insights into data access and storage usage, organizations can ensure adherence to regulatory requirements, helping in audits and aligning with best practices for data governance.

4. Performance Benchmarking: Deploy the plugin to benchmark the performance of data retrieval and storage operations in Google Cloud Storage. By analyzing metrics over time, teams can identify performance bottlenecks or inefficiencies, allowing them to optimize their applications and infrastructure that depend on cloud storage services.

DuckDB

1. Embedded Metric Warehousing for Notebooks: Write metrics to a local DuckDB file from Telegraf and analyze them in Jupyter notebooks using Python or R. This workflow supports reproducible analytics, ideal for data science experiments or offline troubleshooting.

2. Batch Time-Series Processing on the Edge: Use Telegraf with DuckDB on edge devices to log metrics locally in SQL format. The compact storage and fast analytical capabilities of DuckDB make it ideal for batch processing and low-bandwidth environments.

3. Exploratory Querying of Historical Metrics: Accumulate system metrics over time in DuckDB and perform exploratory data analysis (EDA) using SQL joins, window functions, and aggregates. This enables insights that go beyond what typical time-series dashboards provide.

4. Self-Contained Metric Snapshots: Use DuckDB as a portable metrics archive by shipping .duckdb files between systems. Telegraf can collect and store data in this format, and analysts can later load and query it using the DuckDB CLI or integrations with tools like Tableau and Apache Arrow.
