containers-telegraf

Telegraf container for monitoring various services and applications.

This container is based on the official Telegraf Alpine image and provides several configuration profiles:

• telegraf_debug.conf: Full metrics collection (all fields enabled) - use for performance analysis and system debugging
• telegraf_production.conf: Optimized with fieldinclude filters for reduced ingestion - use for production monitoring with resource optimization

Dynamic detection of host comptability for the following plugins:

• [[inputs.linux_cpu]] cpufreq plugin
• [[inputs.linux_cpu]] thermal plugin

Usage

Build the container

docker build -t telegraf .

Runtime configuration

Environment variables:

• TELEGRAF_CONFIG_LEVEL: the configuration profile to use (default: production; options: debug, production)
• TELEGRAF_CONFIG_FILE: override the configuration file path (default: /etc/telegraf/telegraf_$TELEGRAF_CONFIG_LEVEL.conf)
• TELEGRAF_HOSTNAME: the hostname to use in the InfluxDB output plugin (default: telegraf)
• REDIS_SERVERS: auto-detected from available Redis instances (redis-local, redis-master, redis-slave)
