@@ -39,6 +39,11 @@ metrics as they pass through Telegraf:
Both Aggregators and Processors analyze metrics as they pass through Telegraf.
Use [measurement filtering](CONFIGURATION.md#measurement-filtering)
to control which metrics are passed through a processor or aggregator. If a
metric is filtered out the metric bypasses the plugin and is passed downstream
to the next plugin.
**Processor** plugins process metrics as they pass through and immediately emit
results based on the values they process. For example, this could be printing
all metrics or adding a tag to all metrics that pass through.
