Python client and url params

[Rémi Verchère]

Hi,

I'm using the python client with a custom collector to export some data.

I use the basic start_http_server to run the exporter.

Does it support url params (i.e http://localhost:8000?target=10.0.0.1 to collect data from 10.0.0.1)? How can I handle it?

If not, do I have to use a specific handler to manage it?

Thanks for your help!

Can you explain more about what you're trying to do?

Usually an exporter only talks to one instance, so there's no need to pass a target.

I'm writing a vmware_exporter to get VMs metrics, and I'd like to use url params to choose the hypervisor or vcenter the exporter has to connect to (see https://github.com/rverchere/vmware_exporter/issues/5), having the same behavior as the snmp_exporter / blackbox exporter

The exporter use very basically the python prometheus_client.

Thanks,

That's a non-standard use case, so it's more difficult to do. You'll want to code up your own HTTP handler and use a custom registry. I'd suggest looking at the snmp_exporter back when it was in Python: https://github.com/prometheus/snmp_exporter/tree/0a189cb62438081e3dc7b78a436b620ca668116c/snmp_exporter
