Motivation¶

In #167051 we discovered that our testing of telegraf is not optimal and @nicksinger stumbled over https://github.com/influxdata/telegraf/tree/master/plugins/outputs/health#health-output-plugin - this could be used to replace the current pipeline approach of logging into the monitoring host and executing telegraf --test. Instead the healtcheck could be configured to only monitor relevant plugins (e.g. only inputs but no custom scripts) and polled on demand (e.g. in pipelines crated by MRs) to instantly inform about the health of that service and gathered metrics.
