ActiveMQ and SQLite Integration

Input and output integration overview

The ActiveMQ Input Plugin collects metrics from the ActiveMQ message broker through its Console API, providing insights into the performance and status of message queues, topics, and subscribers.

Telegraf’s SQL output plugin stores metrics in an SQL database by creating tables dynamically for each metric type. When configured for SQLite, it utilizes a file-based DSN and a minimal SQL schema tailored for lightweight, embedded database usage.

Integration details

ActiveMQ

The ActiveMQ Input Plugin interfaces with the ActiveMQ Console API to gather metrics related to queues, topics, and subscribers. ActiveMQ, a widely-used open-source message broker, supports various messaging protocols and provides a robust Web Console for management and monitoring. This plugin allows users to track essential metrics including queue sizes, consumer counts, and message counts across different ActiveMQ entities, thereby enhancing observability within messaging systems. Users can configure various parameters such as the WebConsole URL and basic authentication credentials to tailor the plugin to their environment. The metrics collected can be used for monitoring the health and performance of messaging applications, facilitating proactive management and troubleshooting.

SQLite

The SQL output plugin writes Telegraf metrics to an SQL database using a dynamic schema where each metric type corresponds to a table. For SQLite, the plugin uses the modernc.org/sqlite driver and requires a DSN in the format of a file URI (e.g., ‘file:/path/to/telegraf.db?cache=shared’). This configuration leverages standard ANSI SQL for table creation and data insertion, ensuring compatibility with SQLite’s capabilities.

Configuration

ActiveMQ

[[inputs.activemq]]
  ## ActiveMQ WebConsole URL
  url = "http://127.0.0.1:8161"

  ## Required ActiveMQ Endpoint
  ##   deprecated in 1.11; use the url option
  # server = "192.168.50.10"
  # port = 8161

  ## Credentials for basic HTTP authentication
  # username = "admin"
  # password = "admin"

  ## Required ActiveMQ webadmin root path
  # webadmin = "admin"

  ## Maximum time to receive response.
  # response_timeout = "5s"

  ## 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

SQLite

[[outputs.sql]]
  ## Database driver
  ## Valid options: mssql (Microsoft SQL Server), mysql (MySQL), pgx (Postgres),
  ## sqlite (SQLite3), snowflake (snowflake.com), clickhouse (ClickHouse)
  driver = "sqlite"

  ## Data source name
  ## For SQLite, the DSN is a filename or URL with the scheme "file:".
  ## Example: "file:/path/to/telegraf.db?cache=shared"
  data_source_name = "file:/path/to/telegraf.db?cache=shared"

  ## 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
  ## The values on the left are the data types Telegraf has and the values on the right are the SQL types used when writing to SQLite.
  #[outputs.sql.convert]
  #  integer       = "INT"
  #  real          = "DOUBLE"
  #  text          = "TEXT"
  #  timestamp     = "TIMESTAMP"
  #  defaultvalue  = "TEXT"
  #  unsigned      = "UNSIGNED"
  #  bool          = "BOOL"

Input and output integration examples

ActiveMQ

1. Proactive Queue Monitoring: Use the ActiveMQ plugin to monitor queue sizes in real-time for a high-volume trading application. This implementation allows teams to receive alerts when queue sizes exceed a certain threshold, enabling rapid response to potential downtime caused by backlogs, thereby ensuring continuous availability of trading operations.

2. Performance Baselines and Anomaly Detection: Integrate this plugin with machine learning frameworks to establish performance baselines for message throughput. By analyzing historical data collected through this plugin, teams can flag anomalies in processing rates, leading to quicker identification of issues impacting service reliability and performance.

3. Cross-Messaging System Analytics: Combine metrics from ActiveMQ with those from other messaging systems in a centralized dashboard. Users can visualize and compare performance data, such as enqueue and dequeue rates, providing valuable insights into the overall messaging architecture and assisting in optimizing the message flow between different brokers.

4. Subscriber Performance Insights: Leverage the subscriber metrics collected by this plugin to analyze behavior patterns and optimize configuration for consumer applications. Understanding metrics such as dispatched queue size and counter values can guide adjustments to improve processing efficiency and resource allocation.

SQLite

1. Local Monitoring Storage: Configure the plugin to write metrics to a local SQLite database file. This is ideal for lightweight deployments where setting up a full-scale database server is not required.
2. Embedded Applications: Use SQLite as the backend for applications embedded in edge devices, benefiting from its file-based architecture and minimal resource requirements.
3. Quick Setup for Testing: Leverage SQLite’s ease of use to quickly set up a testing environment for Telegraf metrics collection without the need for external database services.
4. Custom Schema Management: Adjust the table creation templates to predefine your schema if you require specific column types or indexes, ensuring compatibility with your application’s needs.
