Model: OC200  
Hardware Version: V2
Firmware Version: 5.18

Hello, I'm working on the syslog collector using Grafana Alloy to send to Loki.

 

However, i;ve got issue that log message from Omada is not fully compliant with RFC5424  (https://datatracker.ietf.org/doc/html/rfc5424#section-6.2.3)

To be specific, the timestamp did not comply RFC3339 .

 

Log message from Omada to my log collectors : 

 

01:37:35.531863 IP static.vnpt.vn.33216 > 172.17.0.8.syslog: SYSLOG local0.info, length: 149

E.../f@.4...q.2...........-.<134>1 2025-04-17 01:36:46 Omada Controller_P1VCP_OC200 - - - DHCP Server allocated IP address 192.168.1.109 for the client[MAC: 3e-d3-e4-ab-5d-63].

 

 

The correct format of RFC5424/RFC3399 should be : 2025-04-15T01:36:46.000000Z

Hi  @Hahahihi 

 

We had a newer version with Built-in Omada SDN Controller v5.15.20.38.

 

Please update to it and see it that time format corrects.

Hi  @Hahahihi 

 

This is because the firmware is not released on the sg website yet. Thanks for bringing ths to us, I will feedback this to our relevant team.

 

For now, you can update it manually.

 

1. Download the firmware from en website;

2.  Manually upload the firmware from Global View > System Settings > Hardware Controller > Manual Upgrade:

Hi Mate, 


So we are on the same boat. 

What is your Log collector ? 

 

 

My original plan is using grafana Alloy as the Log Collector but it strictly require RFC compliance hence my temporary solution is using Datadog Vector as the log collector.

 

My interim arch : 

Omada ---> Vector ---> Loki ----> Grafana. 

 

give it a try and hit me if you need any help.

Using Loki. Don´t know the exact error message I got anymore but it was indeed due to the logs not being exactly RFC compliant. So hoping for a fix in the Sofware controller as well :) Currently running latest version 5.15.20.18
