Input and output integration overview
The MQTT Telegraf plugin is designed to read from specified MQTT topics and create metrics, enabling users to leverage MQTT for real-time data collection and monitoring.
The Google BigQuery plugin allows Telegraf to write metrics to Google Cloud BigQuery, enabling robust data analytics capabilities for telemetry data.
Integration details
MQTT
The MQTT plugin allows for reading metrics from specified MQTT topics, creating metrics using supported input data formats. This plugin operates as a service input, which listens for incoming metrics or events rather than gathering them at set intervals like normal plugins. The flexibility of the plugin is enhanced with support for various broker URLs, topics, and connection features, including Quality of Service (QoS) levels and persistent sessions. Its configuration options incorporate global settings to modify metrics and handle startup errors effectively. It also supports secret-store configurations for securing username and password options, ensuring secure connections to MQTT servers.
Google BigQuery
The Google BigQuery plugin for Telegraf enables seamless integration with Google Cloud’s BigQuery service, a popular data warehousing and analytics platform. This plugin facilitates the transfer of metrics collected by Telegraf into BigQuery datasets, making it easier for users to perform analyses and generate insights from their telemetry data. It requires authentication through a service account or user credentials and is designed to handle various data types, ensuring that users can maintain the integrity and accuracy of their metrics as they are stored in BigQuery tables. The configuration options allow for customization around dataset specifications and handling metrics, including the management of hyphens in metric names, which are not supported by BigQuery for streaming inserts. This plugin is particularly useful for organizations leveraging the scalability and powerful query capabilities of BigQuery to analyze large volumes of monitoring data.

Input and output integration examples
MQTT
-
Smart Home Monitoring: Use the MQTT Consumer plugin to monitor various sensors in a smart home setup. In this scenario, the plugin can be configured to subscribe to topics for different devices, such as temperature, humidity, and energy consumption. By aggregating this data, homeowners can visualize trends and receive alerts for unusual patterns, enhancing the overall quality and efficiency of home automation systems.
-
IoT Environmental Sensing: Deploy the MQTT Consumer to gather environmental data from sensors distributed across different locations. For instance, this can include readings from air quality sensors, temperature sensors, and noise level meters. The plugin can be configured to extract relevant tags and fields from the MQTT topics which allows for detailed analyses and reporting on environmental conditions at scale, supporting better decision making for urban planning or environmental initiatives.
-
Real-Time Vehicle Tracking and Telemetry: Integrate the MQTT Consumer plugin within a vehicle telemetry system that collects data from various sensors in real-time. With the plugin, metrics related to vehicle performance, location, and fuel consumption can be sent to a centralized monitoring dashboard. This real-time telemetry data enables fleet managers to optimize routes, reduce fuel costs, and improve vehicle maintenance schedules through proactive data analysis.
-
Agricultural Monitoring System: Leverage this plugin to collect data from agricultural sensors that monitor soil moisture, crop health, and weather conditions. The MQTT Consumer can subscribe to multiple topics associated with farming equipment and environmental sensors, allowing farmers to make data-driven decisions to improve crop yields while also conserving resources, enhancing sustainability in agriculture.
Google BigQuery
-
Real-Time Analytics Dashboard: Leverage the Google BigQuery plugin to feed live metrics into a custom analytics dashboard hosted on Google Cloud. This setup would allow teams to visualize performance data in real-time, providing insights into system health and usage patterns. By using BigQuery’s querying capabilities, users can easily create tailored reports and dashboards to meet their specific needs, thus enhancing decision-making processes.
-
Cost Management and Optimization Analysis: Utilize the plugin to automatically send cost-related metrics from various services into BigQuery. Analyzing this data can help businesses identify unnecessary expenses and optimize resource usage. By performing aggregation and transformation queries in BigQuery, organizations can create accurate forecasts and manage their cloud spending efficiently.
-
Cross-Team Collaboration on Monitoring Data: Enable different teams within an organization to share their monitoring data using BigQuery. With the help of this Telegraf plugin, teams can push their metrics to a central BigQuery instance, fostering collaboration. This data-sharing approach encourages best practices and cross-functional awareness, leading to collective improvements in system performance and reliability.
-
Historical Analysis for Capacity Planning: By using the BigQuery plugin, companies can collect and store historical metrics data essential for capacity planning. Analyzing trends over time can help anticipate system needs and scale infrastructure proactively. Organizations can create time-series analyses and identify patterns that inform their long-term strategic decisions.
