This article explains an unknown syslog output by rpd regarding watermark.

The below messages were logged:

rpd[xxxx]: %DAEMON-5-RPD_RT_TIME_AVRGD_WM_NOTICE: New time averaged watermark for RIB routes xx [Old: xx]

Meaning of the log:
 

RPD_RT_TIME_AVRGD_WM_NOTICE indicates the current routing and forwarding (RIB/FIB) route table (using the time-averaged-watermark-interval)

Time-averaged watermark is calculated whenever the time-averaged interval is changed and logged in Syslog if the logs are enabled in the system at LOG_NOTICE level or higher. The default time-averaged watermark interval is 1 day.

Reason for re-occurrence:

As the default time-averaged watermark is set to 1 day, it is a normal behavior for the device to log this message once in every 24hours.

There is no business impact regarding the below logs on the system because it is just RIB/FIB information. This message reports an event, not an error and this is normally ignorable if it outputs once every 24 hours.

To change the interval of logging:

#set routing-options time-averaged-watermark-interval 15  >> (Selectable value range(Day) is 1~15)

To exclude log message:

#set system syslog file messages match “!(.RPD_RT_TIME_AVRGD_WM_NOTICE.)”
