Configuration

This is an illustrative example of the configuration file in YAML format.

# FlexLM Licenses to be monitored.

licenses:
  - name: app1
    license_file: /usr/local/flexlm/licenses/license.dat.app1
    featurestoexclude: feature1,feature2
    monitor_users: True
    monitor_reservations: True
    monitor_versions: False
  - name: app2
    license_server: 28000@host1,28000@host2,28000@host3
    featurestoinclude: feature5,feature30
    monitor_users: True
    monitor_reservations: True
    monitor_versions: False

Notes:

1. It is possible to define a license with a path in license_file, that has to be readable from the exporter instance, or with license_server in a port@host combination format. 2. You can exclude some features from exporting with featurestoexclude, or export some defined and exclude the rest with featuretoinclude.
