SNMP support for exometer_function

[dergraf]

the current version of exometer_report_snmp.erl can not deal with exometer_function entries. It will run into

{error, {function_not_exported,
{snmp_bin, 1}}}
when calling modify_mib.
Is there a simple workaround besides specifying my own function entry module?

The issue with exometer_function is that they can return arbitrary values, thus one can't really map that to a particular SNMP structure. I think the easiest way forward for you would be to specify a custom module.

@uwiger Any idea how to generalize this?

I thought a bit about that, but am not sure I've arrived at a great solution.

I considered adding an option, {snmp_syntax, binary()} when creating the metric. This could then be used by the exometer_report_snmp:create_bin/3 function. It certainly would be easy enough to implement.

how is it going with this issue.. is there any way I can help with this?

[tolbrino]

I had something in the works for this, will resurrect it.
