Hi Matt, Thank you for your information! I will submit a patch to implement this function. Best Regards, Xu, Chenjie From: Peters, Matt [mailto:Matt.Peters@windriver.com] Sent: Tuesday, September 17, 2019 9:32 PM To: Xu, Chenjie <chenjie.xu@intel.com> Cc: starlingx-discuss@lists.starlingx.io; Zhao, Forrest <forrest.zhao@intel.com>; Khalil, Ghada <Ghada.Khalil@windriver.com> Subject: Re: [Starlingx-discuss] OVS collectd interface/port state monitoring Hi Chenjie, Yes, the dump-ports-desc can be used to obtain the current port state and negotiated state with the peer. This data will need to be mapped back to the data interface mapping of the host so that the appropriate alarms may be raised against the proper entity. In addition, if the data interface is a bond, the following information will also have to be retrieved in order to obtain the full state of the bond interface, including LACP information (if applicable). ovs-appctl bond/show ovs-appctl lacp/show Finally, the alarming behavior should be the following: Data port is down and does not belong to a bond – Critical Alarm Data port(s) down, but enabled port remains in bond – Major Alarm (degraded service) All data ports down in a bond – Critical Alarm From: "Xu, Chenjie" <chenjie.xu@intel.com<mailto:chenjie.xu@intel.com>> Date: Monday, September 16, 2019 at 11:32 PM To: "Peters, Matt" <Matt.Peters@windriver.com<mailto:Matt.Peters@windriver.com>> Cc: "starlingx-discuss@lists.starlingx.io<mailto:starlingx-discuss@lists.starlingx.io>" <starlingx-discuss@lists.starlingx.io<mailto:starlingx-discuss@lists.starlingx.io>>, "Zhao, Forrest" <forrest.zhao@intel.com<mailto:forrest.zhao@intel.com>>, Ghada Khalil <Ghada.Khalil@windriver.com<mailto:Ghada.Khalil@windriver.com>> Subject: [Starlingx-discuss] OVS collectd interface/port state monitoring Hi Matt, For task “OVS collectd interface/port state monitoring”, which parts should be monitored?
