lvm-exporter

---

This repository provides code for a Prometheus metrics exporter for LVM. This exporter can be run as a seperate daemonset or as a sidecar container.

This exporter makes use of prometheus-go-client, the official Go client library for prometheus.

The following metrics/labels are being exported:

lvm_lv_total_size{device="",lv_active="",lv_dm_path="",lv_full_name="",lv_name="",lv_path="",lv_uuid="",vg_name=""} TOTAL_SIZE
lvm_vg_free_size{vg_name=""} FREE_SIZE
lvm_vg_total_size{vg_name=""} TOTAL_SIZE

To publish container to Docker

• Update DOCKER_REPO in deploy.env with you own dockerhub repo name.
• Run make all in the top directory. It will:
  • Build the docker image with the binary and will publish it in your docker repo.

To deploy:

• Run it as a daemonset or as a sidecar container.
  • Please visit examples for daemonset yamls and how to deploy it.

To run lvm-exporter as textfile-collector with node-exporter

• The textfile collector is similar to the Pushgateway, in that it allows exporting of statistics from batch jobs. It can also be used to export static metrics, such as what role a machine has. The Pushgateway should be used for service-level metrics. The textfile module is for metrics that are tied to a machine.

• To use it, set the --collector.textfile.directory flag on the node_exporter commandline. The collector will parse all files in that directory matching the glob *.prom using the text format.

• To deploy lvm-textfile-collector with node-exporter:

  • Please visit lvm-textfile-collector to build image and use it with node-exporter
