Combined bandwidth threshold help

[_sjm_]

I'm trying to trigger an alert on combined bandwidth (in/out) usage. I set the value for the trigger trying to use the RPN Expression of |ds:traffic_in|,|ds:traffic_out|,+ but it seems the value for the trigger is only |ds:traffic_in| . Am I missing something?

I have encountered the same problem with the multi-cpu template.
I need to set a threshold based on the mean between two cpu, but when i use a custom cdef (a,b,+,2,/), i receive a value not correct for my purpose.
For example how i can add a third data source based on the sum of the two cpu ???
Thanks in advance for your reply and excuse me for my bad english

You should try enabling the following lines from the "thold_functions.php" file ( remove the "//" in front of the cacti_log):

Code: Select all

692        //cacti_log(implode(",", array_keys($data_sources)));
693        //cacti_log(implode(",", $data_sources));
694        //cacti_log(implode(",", $expression));

then check your cacti log for some additional info.
