The OLT does not (logging is only briefly cached), but ZMS should have that data. ________________________________ From: Mike Hammett via NANOG <nanog@lists.nanog.org> Sent: Saturday, April 5, 2025 2:59 PM To: North American Network Operators Group <nanog@lists.nanog.org> Cc: Mike Hammett <nanog@ics-il.net> Subject: [NANOG] DZS - ZMS Given DZS filing chapter 7, I doubt I'll get much support asking the company itself. Does anyone know if ZMS (or the OLT) carries historical information about ONU statuses? I have a current ONU status, but no idea when it was set, if it's changed, etc. I just found out that my recent upgrade of my monitoring server resulted in the syslog package being uninstalled, so I had to reinstall it... of course losing all syslog messages from when until now. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com _______________________________________________ NANOG mailing list https://lists.nanog.org/archives/list/nanog@lists.nanog.org/message/CVGL2EAS...
