It's my understanding that the "service=XYZ" option is used to find a match in graphs.cfg (ie [XYZ]). Usually this is the same string as the column name, but sometimes not, and I have to admit that I don't fully understand the relationships between RRD filename, graph name, column name, service name, the variables TEST2RRD and GRAPHS and the per-host TRENDS settings.

Ah, that got it. I had REQUEST_METHOD=get on the same line as SCRIPT_NAME, effectively making the command ?showgraph REQUEST_METHOD=GET?
Also, the QUERY_STRING does not want the ncv: in it.
ConfigPulls yields:
$ $SCRIPT_NAME

While cpu, and another custom graph we have (proc-mem) both work fine.
I?m thinking the upper case maybe causing the issue. I?m going to try to rename the test to lowercase.

Following your commands, the only suggestion is that the variables might not have been set correctly. Perhaps run "echo $QUERY_STRING; echo $REQUEST_METHOD; echo $SCRIPT_NAME" immediately before "$SCRIPT_NAME".
In case my instructions were amiss, here's another example of debugging showgraph.sh to follow:

Looping back on this:
Running the showgraph by hand

This won't work. The showgraph.cgi binary expects to be run as a CGI and requires QUERY_STRING to be set (to host=nsmdenvp185&service=ncv:ConfigPulls&graph_width=...) and REQUEST_MATHOD to be set to "GET". It also expects SCRIPT_NAME to be set (and normally it would be showgraph.sh) but I think this only generates warnings.
Try running like so:
SCRIPT_NAME=showgraph.sh REQUEST_METHOD=GET QUERY_STRING='host=nsmdenvp185&service=ncv:ConfigPulls&graph_width=576&graph_height=120&disp=nsmdenvp185&nostale&color=blue&graph_start=1568489816&graph_end=1568662616&graph=hourly&action=view' ./showgraph.sh
The output will be partly binary, so you might want to try:
SCRIPT_NAME=showgraph.sh REQUEST_METHOD=GET QUERY_STRING='host=nsmdenvp185&service=ncv:ConfigPulls&graph_width=576&graph_height=120&disp=nsmdenvp185&nostale&color=blue&graph_start=1568489816&graph_end=1568662616&graph=hourly&action=view' ./showgraph.sh | sed '1,/^$/d' | file -
and see if it shows that a PNG file format was generated.
If this doesn't work, check for a service name such as "cpu" that is known to work, rather than your custom "ncv:ConfigPulls".

Yep, cos no QUERY_STRING.
