Challenge

When a name of a cluster contains unsupported characters, the following error can occur in the Enterprise Manager log (server.txt file):
INFO  IMon  Error:
System.ArgumentException: An item with the same key has already been added.
at System.ThrowHelper.ThrowArgumentException(ExceptionResource resource)
at System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add)
at System.Collections.Generic.Dictionary`2.Add(TKey key, TValue value)
at Veeam.LicenseServer.InfrastructureMonitor.createDictionary(ClusterInfo[] state)
at Veeam.LicenseServer.InfrastructureMonitor.queryChanges()
at Veeam.LicenseServer.InfrastructureMonitor.go(Object data)

As a result, the cluster will not appear in nworks Enterprise Manager Web UI.

Cause

nworks 5.6 does not support brackets in names of clusters.

Solution

Remove brackets from the cluster name, or upgrade to nworks 5.7.
