Wrong "Current Value" THOLD
Describe the bug Incorrectly displayed "current value on 10G ports and port-channel" configured (CDEF convert bytes to bits) periodically shows incorrect value. Examples of the problem are given in the screens. Also is it possible to make a single template for 10G + ports and apply. Because at the moment for each port I select values separately which is not convenient. But also periodically sends incorrect data to alert. Thold installed via Git v1.5.2

We are off working on other things at the moment. You are free to create a pull request though.
actual traffic_out = 99Mbit. You are using CDEF convert bytes to bits, so 99 * 8 = 792Mbit ... I thing that here is problem. Your traffic_out is in mbits and you are trying convert in again.
same problem is #540 , #549, #551 I thing that there were more problems:
-
graph says that traffic_in = 10mbit/s, but thold says traffic_in last = 80mbit (incorrect, used data manipulation/cdef bytes to bits). I cannot reproduce this with cacti 1.2.23 and thold 1.6
-
graph says that traffic_in = 10mbit/s, thold says traffic_in last = 10mbit (correct) but data source item[traffic_in] says = 640Mbit. moretime used CDEF. I cannot reproduce this with cacti 1.2.23 and thold 1.6

graph says that traffic_in = 10mbit/s, thold says traffic_in last = 10mbit (correct) but data source item[traffic_in] says = 80 Mbit. It is caused by data manipulation. For last traffic_in is used thold_format_number($td['lastread'], 2, $baseu, $suffix, $show_units), for data source item is used thold_format_number(thold_get_column_by_cdef($thold_data, 'lastread'), 2, $baseu, $suffix, $show_units) So two different values could be displayed (when any data manipulation).
For me easy fix is remove thold_get_column_by_cdef from displaying data source item. @TheWitness What do you thing? Is it correct?
