openstack_exporter

Prometheus exporter to retrieve OpenStack metrics about limits and status

Usage

usage: main [<flags>]


Flags:
  -h, --[no-]help          Show context-sensitive help (also try --help-long and --help-man).
      --port=9595          Port to serve the metrics on
      --volume.limit=-1    Max number of volumes when on OTC
      --log.level=info     Only log messages with the given severity or above. One of: [debug, info, warn, error]
      --log.format=logfmt  Output format of log messages. One of: [logfmt, json]
      --[no-]version       Show application version.

The --volume.limit is only used when running the exporter on OTC, because we currently have no way of getting the limits via the API.

Authentication

You should authenticate by using environment variables. For OTC, make sure following environment variables are set:

* OS_AUTH_URL
* OS_DOMAIN_NAME
* OS_PASSWORD
* OS_USERNAME
* OS_PROJECT_ID
* OS_ACCESS_KEY
* OS_SECRET_KEY

For CloudFerro, following environment variables are needed:

* OS_AUTH_URL
* OS_USERNAME
* OS_REGION_NAME
* OS_PROJECT_ID
* OS_PASSWORD
* OS_DOMAIN_ID
