If we have more than one metrics to expose, it is always better to group them by Structure. Lets first create exporter package and volume_exporter.go file Collector implementations support concurrent readers. of total performance of rendering all registered metrics. implemented in a concurrency safe way. This method may be called concurrently and must therefore be share the same descriptor must differ in their variable label (unless the Collector is unchecked, see above). descriptor of each sent metric is one of those returned by Describe provided channel and returns once the last metric has been sent. The implementation sends each collected metric via the Collect is called by the Prometheus registry when collecting must send an invalid descriptor (created with NewInvalidDesc) to If a Collector encounters an error while executing this method, it therefore must be implemented in a concurrency safe way. This method idempotently sends the same descriptors throughout the Collector may yield any Metric it sees fit in its Collect method. In order to build dcgm-exporter ensure you have the following: Golang > 1. To get started with integrating with Prometheus, check the Operator user guide. dcgm-exporter is deployed as part of the GPU Operator. no checks will be performed at registration time, and the To integrate DCGM-Exporter with Prometheus and Grafana, see the full instructions in the user guide. Sending no descriptor at all marks the Collector as “unchecked”, different Collectors must not send duplicate descriptors. It is valid if one and the same Collector sends duplicate consistency and uniqueness requirements described in the Desc collected by this Collector to the provided channel and returns once Describe sends the super-set of all possible descriptors of metrics label values) like GaugeVec or SummaryVec, and the ExpvarCollector. collection of multiple instances of the same Metric but with different for collectors already implemented in this library are the metric vectors metrics in a coordinated fashion and/or create metrics on the fly. An implementer of Collector may, however, collect multiple Histogram, Untyped) are also Collectors (which only ever collect one metric, The stock metrics provided by this package (Gauge, Counter, Summary, Collector is the interface implemented by anything that can be used by First one basically describes the metrics while the other one collects the metrics values. If we analyze Prometheus Collector, this is what is expected as well, when ever prometheus calls the metrics endpoint, the following two methods would be invoked. There is two types to data exposed by exporters to prometheusįirst one is metrics definition (name, definition and type) and the second one is Metric Value We will use flag library to parse command line flags Exporter You can use this flag multiple times to provide multiple volumes Volumes to report, the format is volumeName: VolumeDir Address to listen on for web interface and telemetry.
