SNMP - Integer values to floating point

Is it possible to convert the values being received from SNMP monitors to floating point before conversion?

I have some equipment that is reporting environment values as integers - example: room temperature is 257, when it is actually 25.7 deg celcius. I can do the divide by 10 in the monitor, but the value is kept as integer and thus truncated to 25.

This lack of precision in the converted value makes it difficult to spot trends across a day or week, when the variation may be < 1 or 2 deg C through the whole period. I am also wanting to compare the data between several sources, so getting the data into a common format prior to comparison is essential.

The new build resolved my issue. I can now see the properly scaled SNMP values on the device real-time charts as well as the graph reports sent by email.

Build 8.3.17 has the fix for anyone else with this issue.

Hi cbellhouse,

In the SNMP monitor click on the Advanced button and that will give you a way to scale the value. This value is what will be stored in the database not the original value. Here is a link to the SNMP Monitor page for more details.

Unfortunately, I am doing exactly that already. I enter "value/10" in the advanced options | Scale value field, but the value is converted from 259 to 25. I need it to store 25.9. Any way to do that?

Hi cbellhouse,

Make sure that you are using at least v8.3, this feature was just recently added. If you need the latest version you can get it from Here.

Hi Quinn I installed the release candidate you attached (v8.3.1.3), but the same thing happens. I get 257 when the value is not scaled, but 25 when it is.

I tried creating a new SNMP monitor task and doing the SNMP walk to find the value. You can see the raw value, and the data type of integer. Next screen showing the scaled value, no decimal place. Looks exactly the same as the version 8.2 screenshot above.
