Directory Size Exporter

Overview

The directory size exporter is a typical metrics exporter in the Prometheus format. It is meant to run as a sidecar to an application to watch a specific application file storage and export metrics about that storage. At the moment, it is used only as a sidecar for the telemetry-fluent-bit instances to watch the file buffer sizes.

The following configuration options are available:

• log-format - log format parameter for the logger (json or text)
• log-level - log level parameter for the logger (debug, info, warn, error, fatal)
• storage-path - the path to the root directory to be observed by the exporter (default /data/log/flb-storage/)
• metric-name - the metric name to use for the metric exposure (default telemetry_fsbuffer_usage_bytes)
• port - the port under which the metrics will be exposed in the Prometheus format (default 2021)
• interval - interval in seconds at which the exporter should check the storage (default 30)
