     Example 1 (cluster with not recommended architecture)

     $ pgd verify-cluster

     Check                                                                               Status   Groups

     There is always at least 1 Global Group and 1 Data Group                            Ok
     There are at least 2 data nodes in a Data Group (except for the witness-only group) Critical group_b
     There is at most 1 witness node in a Data Group                                     Warning  group_a
     Witness-only group does not have any child groups                                   Ok
     There is at max 1 witness-only group iff there is even number of local Data Groups  Warning  bdrgroup
     There are at least 2 proxies configured per Data Group if routing is enabled        Warning  group_a, group_b

     Example 2 (cluster with recommended architecture)

     $ pgd verify-cluster

     Check                                                                               Status Groups

     There is always at least 1 Global Group and 1 Data Group                            Ok
     There are at least 2 data nodes in a Data Group (except for the witness-only group) Ok
     There is at most 1 witness node in a Data Group                                     Ok
     Witness-only group does not have any child groups                                   Ok
     There is at max 1 witness-only group iff there is even number of local Data Groups  Ok
     There are at least 2 proxies configured per Data Group if routing is enabled        Ok
