1.collect-isis-counters rule, the field name is level-num but in collect-isis-lsdb-lsp it is level-numb, please keep naming constant across all rules.
2.collect-isis-lsdb-neighbsysid has maultiple keys ( instance-name protocol-name level-num lsp-id tlv-value neighb-sysid ), can this be reduced?
3.Add the requirement number if available for all rules.
4.collect-isis-lsdb-subtlv rule also has 7 keys, please reduce the number of keys.Check for all rules.
