pprof profile - endpoint |
|
The pprof endpoints are not configurable easily. We would have to custom register our own handlers. We basically need to completely re-work how we handle the web endpoint for exporters to handle this better. Really, I don't think we should be doing this at all. This is too much extra boilerplate and makes our exporters inconsistent. The fact that this has been hand-implemented by the blackbox exporter, and this PR is a mess of additional code, shows that we should not be doing this. |

Shouldn't these flags be part of github.com/prometheus/exporter-toolkit/web/kingpinflag?
This is a duplicate of #1328
Sorry for the duplicate. Didn't realize deleting my branch would auto-close the pull request. Anyways... 🤦♂️
Add feature to serve application behind a route prefix or external URL by supplying args --web.external-url/--web.route-prefix, in the same way as blackbox_exporter or other exporters.
I am also submitting a pull request for exporter-toolkit so that this will actually work. Currently you cannot serve the landing page on anything other than root ("/"), so the tests are going to fail initially.
I would consider these additional args to be "must-have" features to bring snmp_exporter closer to feature parity with the other exporters. I needed to serve this exporter behind a prefix like I'm doing with the other exporters, so I figured I would make an attempt at this update myself, as it does appear to be something other people have been wanting for quite some time.
