One of our nodes uses a multi-target exporter, in shorts we do this to retrieve metrics:
curl $HOST/probe?target=http://anotherhost.com/data
We’re evaluating PMM and I’m trying to add this exporter as an external service with pmm-admin
like this:
pmm-admin --debug add external --listen-port XXXX --service-name=XXXX --metrics-path="/probe?target=http://anotherhost.com/data
but it doesn’t work, I get this error:

I’ve also tried with and without double quotes in the metrics-path value but still no luck.
Does anyone know if pmm-admin can handle multi-target exporters?
Thank you in advance.
