I'm really sorry, this needs a rebase, but otherwise lgtm! And sorry again for this slipping through the cracks, so thank you for pinging me again. In the future also feel free to ping me on the Parca Discord server if you want to make sure to get a faster review! :) |
this updates the definition of `PprofProfilingConfig` such that a new integer field `Seconds` is added which can be set for profiles. additionally, it changes the behavior where setting any profiling configurations will end up overriding the default so merge will now become a replace. seconds is accepted as a query parameter and with this change, when provided, it will be used as scraping duration rather than the scraping interval value. this allows having scraping where process being profiled isn't under constant profiling. this only applies to configurations that have delta enabled. https://pkg.go.dev/net/http/pprof
