Missing Graphs and Ports for Mikrotik Device During Daytime (High Traffic)

Hello,

I am experiencing an issue where graphs are missing and some used interfaces do not appear in LibreNMS for a Mikrotik 1036 device during the daytime, when the ports handle high traffic (around 2G). The port is a 10G interface, and when traffic spikes, the specific ports’ graphs are not displayed.

Interestingly, during the night (low traffic period), the graphs appear as expected, and the ports show up as well. The issue seems to be confined to the daytime hours when the traffic load is significantly higher.

I have attached the device graph and some relevant logs/screenshots to illustrate the issue.

I wonder if there is a polling issue during the period of missing data, taking too long or not responding? Maybe try manually polling during high traffic time and see if there is anything odd. lnms device:poll <device-id>
