Listing Cluster Licenses

The node licenses command displays license status information for each node in a cluster:

> grbcluster node licenses
ID       ADDRESS   STATUS TYPE     KEY   EXP ORG    USER APP VER CS    DL  ERROR
eb07fe16 server1   VALID  NODE               gurobi          8   true  0
b7d037db server2   VALID  NODE               gurobi          8   true  0

Add the —describe flag to see an explanation of each field:

> grbcluster node licenses --describe
ID        - Unique node ID, use --long to display full ID
ADDRESS   - Node address

TYPE      - License type
KEY       - License Cloud Key (not displayed if empty or restricted)
EXP       - License expiration

If a node has an INVALID license, you can run the following command to learn more:

> grbcluster node licenses
ID       ADDRESS STATUS  TYPE KEY EXP ORG USER APP VER CS    DL  ERROR
eb07fe16 server1 INVALID NODE                          false 0   No Gurobi license found...

Note that the node licenses command can be used at any time to check the validity and attributes of licenses on all the nodes of the cluster (expiration date, distributed limit, etc.).
