Using sensor alert with the following conditions:
sensor_value greater @sensor_limit
sensor_value less @sensor_limit_low
No predefined or custom values using hh3c-transceiver-info-mib
Still getting alerts even though /device/device=id/tab=health/metric=dbm/ shows no errors
Also ports that are shutdown will still alert if the values are out of bounds..

Where can I see the autogenerated value?
And isn't the info under /device/device=id/tab=health/metric=dbm/ correlated with the alerting function, meaning if there are alarms in that view, there would be an alert trigger if configured and vice versa
Regards

It's not actually possible for there not to be thresholds on a sensor, if they are removed, the system will autogenerate them based on the most recent value. It's likely that the autogenerated value isn't useful and the measured value is frequently bouncing out of the threshold range.
You can prevent alerts being generated for a sensor using the "Alerts" slide on the same options page, and/or by setting the threshold so it can't be tripped.
Whether the port underneath the sensor is up or down doesn't actually figure into the alerting at all, since the two are rarely connected in a way that makes this easy to handle.
The thresholds should regenerate after a discovery and be present in all of the places thresholds are present (on graphs as the dotted line, on tables as the threshold entry and on the settings page)
The status of the table on that page is historical, and applies the thresholds during page generation rather than taking into account any alerter entries that may exist for that entity.
