description                 \
    The plugin-driven server agent for collecting & reporting metrics.

long_description            \
    Telegraf is an agent for collecting, processing, aggregating, and writing \
    metrics.  Design goals are to have a minimal memory footprint with a \
    plugin system so that developers in the community can easily add support \
    for collecting metrics. Telegraf is plugin-driven and has the concept of \
    4 distinct plugin types: input plugins, processor plugins, aggregator \
    plugins, and output plugins.

To start the Telegraf service, use `port load`: \$ sudo port load ${name}

Once running, the service will log to: ${telegraf_log_file}

Stop and remove the service with: \$ sudo port unload ${name}
