Hello all,
I'm very new to Zenoss Core and how RRD graphing works in general.
I have a temp probe from RoomAlert. I've installed the MIBs and SNMP is working correctly. snmpwalk works.
I wanted to create a custom graph of the temperature returned by the probe.
Under the Monitoring Templates I setup a new template. bound it to my device tree. Setup my data sources, data points, and add to a new graph.
When I test the data source it returns what I expect "SNMPv2-SMI::enterprises.20916.1.9.1.1.2.2.0 = INTEGER: 7152" as in 71.52 Fahrenheit.
The graph defaults to %5.2lf%s so it formats my data into 7.15k not 71.52.
In the Graph i manage the graph points. Change the format to %7.2lf (or anything). Save that all. re-model.
But the graph either fails to returns any data or will only show it as the default 7.15k.
What am i missing

Zenoss 5 don't use RRDs, but data are stored in OpenTSDB now. Probably backward compatibility with RRD custom graph definition is not fully implemented and it's root cause of your problem. I recommend you to check Zenoss 5 docs/githubs/manuals/...

Fixed my issue.
Nothing I did in the "format" field would help me change the format of the data points. Regardless of what the rrdtool's doc says. To me it feels like zenoss5 is ignoring that field.
In the end what fixed my problem was using the RPN field when you manage graph points (under graphs).
SNMP returned values like 7255. Zenoss would graph them like 7.255k.
For the RPN i entered "100,/" as in divide that number by 100. Making the data show up as 72.55. Basically moving the decimal point.
