This got broken in
78047326b4
since it stopped using the DefaultServeMux.
This approach will defer pprof requests to the DefaultServeMux, which
may or may not have pprof enabled (in Prometheus, it gets it included in
main.go). An alternative approach would be to duplicate the four lines in
https://golang.org/src/net/http/pprof/pprof.go#L62. When choosing that
approach though, we would not automatically gain any new endpoints added
by net/http/pprof or other /debug endpoints in the future.
Besides fixing https://github.com/prometheus/prometheus/issues/805 by
making the entire externally reachable server URL configurable, this
adds tests for the "globalURL" template function and makes it easier to
test other such functions in the future.
This breaks the `web.Hostname` flag (and introduces `web.external-url`).
This flag is likely only used by few users, so I hope that's
justifiable.

Also remove hidden input fields that are not used anymore, because the
query params are now passed as JSON to the AJAX function. This also has
the wonderful side effect that we're no longer sending all the other
non-hidden fields along to the query endpoints anymore.
Changes to the UI:
- "Active Since" timestamps are now human-readable.
- Alerting rules are now pretty-printed better.
- Labels are no longer just strings, but alert bubbles (like we do on
the status page for base labels).
- Alert states and target health states are now capitalized in the
presentation layer rather than at the source.
This commit adds a federation handler on /federate. It accepts `match[]`
query parameters containing vector selectors. Their intersection determines
the in-memory metrics that are returned in the same way as the
/metrics endpoint does (modulo sorting).
Version information is determined at build-time and thus there is
no need to pass it down from main. In its own package it can
be used from various other packages.
Also, rearrange and clean up some things to make this work.
The textarea starts as a single line, but auto-expands when entering
multiple lines (e.g. via Shift+Enter). Pressing just "Enter" still
executes the expression.
Main changes:
- Switched to using `go-bindata` in place of `scripts/embed-static.sh`.
- Support for building Prometheus without a `Makefile`.
- Minor typo fix to make Prometheus build on Windows (without Makefiles).
Please note that this does not mean that prometheus will work on Windows.
There are still failing tests!
Figuring out what's going on with the new service discovery
and labels is difficult. Add a popover with the labels
to the target table to make things simpler, and help
discovery of potentially useful labels.
