The introduction of pull support in InfluxDB's Kapacitor 1.3 beta release allows for a standardized way of exposing targets for metrics data collection, reducing the effort required to write collectors and making it easier for services and applications of all kinds to expose their metrics data. This is achieved through service discovery and scraping, similar to Prometheus, which enables outside systems to collect telemetry data from applications without them sending data to a new service. The pull method has its advantages, such as allowing any outside system to collect telemetry data, but also has limitations, including the need for periodic polling of targets. Kapacitor's integration with Prometheus' service discovery and scraping code provides a standardized way to expose targets and collect metrics data, making it easier to implement pull monitoring and collection in InfluxDB.
