I am using 4B3, but used to use 3.6.
I have a problem with bandwidth charting (which applies to all charting). If I have a really high piece of data (whether false or true). The chart autoscales to an unuseable amount. I cannot see any of the other data (e.g. usually 4mbit, surge to 1 gbit). This is a major problem, for I cannot zoom in and see the detail near the time of the surge. Is there a hidden method to set a max value for the scale for each chart?
I have considered modifying a function to limit the value, but of course this would not work for the automatically measured bandwidth numbers on a link (mastering configured).
Suggestions?? Thanks.
In 3.6 if you open the chart tool and keep diving down to the graph then to advanced you can find the spike in the data since you can see the raw collected values. You could modify that data to eliminate the spike. This is gone in 4x.

I am bumping this in hopes that someone has an idea.
I have a probe on a device for bandwidth. The function is
8 * rate( diff32(oid("iso.org.dod.internet.mgmt.mib-2.interfaces.ifTable.ifEntry.ifInOctets.2",10,5)) + diff32(oid("iso.org.dod.internet.mgmt.mib-2.interfaces.ifTable.ifEntry.ifOutOctets.2",10,5)) )
While the probe is simply a function probe. This provides total bandwidth on interface 2. It works great, unless the packet fails. In this situation, no data is provided, and then the next time it receives data, it spikes to a high number (rather than interpolate over the time period).
By contrast, on a (Dude) Link, I can graph the bitrate on the interface and get a chart for RX and TX that does not provide false spikes.
PLEASE, help, or if this is confusing, ask questions!!

Maybe just re-organize your probe so the multiplication takes place and causes a 0 value instead of a huge value.
Here is a rate calculator on g0/0 of a router - no i did not double check what would happen… ok i will try, no i wont.
string_substring((((rate(diff32(oid(“1.3.6.1.2.1.2.2.1.10.1”))+diff32(oid(“1.3.6.1.2.1.2.2.1.16.1”)))/diff32(oid(“1.3.6.1.2.1.2.2.1.5.1”))))*8),0,4)
