defIT_RES_USAGE_P_75 トリガーされたアラートのマッピング：

mapsdb --show の出力から、dflt_moderate_policy がアクティブポリシーであることがわかります。

1 Dashboard Information: ======================= DB start time: Mon May 15 22:10:32 2023 Active policy: dflt_moderate_policy Configured Notifications: RASLOG,SNMP,SW_CRITICAL,SW_MARGINAL,SFP_MARGINAL,SDDQ,UNQUAR,RE_BALANCE Fenced Ports : None Decommissioned Ports : None Fenced circuits : None Quarantined Ports : None Top Zoned PIDs <pid(it-flows)>: 0x6f6dxx(60) 0x6f6cxx(60) 0x6fcbxy(60) 0x6f2dxy(60) 0x6fcbyy(60)

上記のmapsdb --show 出力では、IT_FLOW比率が最も高いPID/エンドデバイスも表示されます。これらはerrdump のエラーログにも表示されます。
