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.

Clickhouse

Telegraf’s SQL plugin is engineered to write metric data into an SQL database by dynamically creating tables and columns based on incoming metrics. When configured for ClickHouse, it utilizes the clickhouse-go v1.5.4 driver, which employs a unique DSN format and a set of specialized type conversion rules to map Telegraf’s data types directly to ClickHouse’s native types. This approach ensures optimal storage and retrieval performance in high-throughput environments, making it well-suited for real-time analytics and large-scale data warehousing. The dynamic schema creation and precise type mapping enable detailed time-series data logging, crucial for monitoring modern, distributed systems.

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"

Clickhouse

[[outputs.sql]]
  ## Database driver
  ## Valid options include mssql, mysql, pgx, sqlite, snowflake, clickhouse
  driver = "clickhouse"

  ## Data source name
  ## For ClickHouse, the DSN follows the clickhouse-go v1.5.4 format.
  ## Example DSN: "tcp://localhost:9000?debug=true"
  data_source_name = "tcp://localhost:9000?debug=true"

  ## Timestamp column name
  timestamp_column = "timestamp"

  ## Table creation template
  ## Available template variables:
  ##  {TABLE}        - table name as a quoted identifier
  ##  {TABLELITERAL} - table name as a quoted string literal
  ##  {COLUMNS}      - column definitions (list of quoted identifiers and types)
  table_template = "CREATE TABLE {TABLE} ({COLUMNS})"

  ## Table existence check template
  ## Available template variables:
  ##  {TABLE} - table name as a quoted identifier
  table_exists_template = "SELECT 1 FROM {TABLE} LIMIT 1"

  ## Initialization SQL (optional)
  init_sql = ""

  ## Maximum amount of time a connection may be idle. "0s" means connections are never closed due to idle time.
  connection_max_idle_time = "0s"

  ## Maximum amount of time a connection may be reused. "0s" means connections are never closed due to age.
  connection_max_lifetime = "0s"

  ## Maximum number of connections in the idle connection pool. 0 means unlimited.
  connection_max_idle = 2

  ## Maximum number of open connections to the database. 0 means unlimited.
  connection_max_open = 0

  ## Metric type to SQL type conversion for ClickHouse.
  ## The conversion maps Telegraf metric types to ClickHouse native data types.
  [outputs.sql.convert]
    conversion_style = "literal"
    integer          = "Int64"
    text             = "String"
    timestamp        = "DateTime"
    defaultvalue     = "String"
    unsigned         = "UInt64"
    bool             = "UInt8"
    real             = "Float64"

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.

Clickhouse

1. Real-Time Analytics for High-Volume Data: Use the plugin to feed streaming metrics from large-scale systems into ClickHouse. This setup supports ultra-fast query performance and near real-time analytics, ideal for monitoring high-traffic applications.

2. Time-Series Data Warehousing: Integrate the plugin with ClickHouse to create a robust time-series data warehouse. This use case allows organizations to store detailed historical metrics and perform complex queries for trend analysis and capacity planning.

3. Scalable Monitoring in Distributed Environments: Leverage the plugin to dynamically create tables per metric type in ClickHouse, making it easier to manage and query data from a multitude of distributed systems without prior schema definitions.

4. Optimized Storage for IoT Deployments: Deploy the plugin to ingest data from IoT sensors into ClickHouse. Its efficient schema creation and native type mapping facilitate the handling of massive volumes of data, enabling real-time monitoring and predictive maintenance.
