Matt T. Proud 30b1cf80b5 WIP - Snapshot of Moving to Client Model. 2013-06-25 15:52:42 +02:00
Julius Volz 1fe3d3b06b Remove obsolete argument from target handling code. 2013-06-11 17:54:58 +02:00
Julius Volz 51689d965d Add debug timers to instant and range queries.
This adds timers around several query-relevant code blocks. For now, the
query timer stats are only logged for queries initiated through the UI.
In other cases (rule evaluations), the stats are simply thrown away.

My hope is that this helps us understand where queries spend time,
especially in cases where they sometimes hang for unusual amounts of
time.

Julius Volz 56324d8ce2 Make AST query storage non-global. 2013-05-07 13:15:10 +02:00
Matt T. Proud 3b9b1c6ab4 Define dependencies for web. stack concretely.
This commit destroys the use of AppState, which makes passing
concrete state along to various serving components onerous.

Matt T. Proud e86f4d9dfd Convert time readers to represent time in UTC.
Go's time.Time represents time as UTC in its fundamental data type.
That said, when using ``time.Unix(...)``, it sets the zone for the
time representation to the local.  Unfortunately with diagnosis and
our tests, it is a PITA to jump between various zones, even though
the serialized version remains the same.

To keep things easy, all places where times are generated or read
are converted into UTC.  These conversions are cheap, for
``Time.In`` merely changes a pointer reference in the struct,
nothing more.  This enables me to diagnose test failures with fixture
data very easily.

Julius Volz a0d311c9e6 Constantize job name label. 2013-04-15 11:47:54 +02:00
Bernerd Schaefer 8af0bbb3a0 Set job label for targets registered through the API
This is set when jobs are statically registered (see
retrieval/targetmanager.go#L92), and should be set here, too.

Bernerd Schaefer 5e9447996b Set CORS Headers on API requests
By setting Access-Control headers, the Prometheus metrics API can be
accessed by cross-origin javascript applications (e.g., an external
dashboard pulling Prometheus metrics).

Julius Volz dd67ab115b Change GetAllMetricNames() to GetAllValuesForLabel(). 2013-03-26 14:47:07 +01:00
Julius Volz 8e4c5b0cea Use AST query analyzer and views with tiered storage. 2013-03-21 18:16:52 +01:00
Julius Volz 20c5ca1d72 Lower-case web API method arguments. 2013-03-21 18:11:02 +01:00
Julius Volz f1fc7d717a Allow replacing job targets via HTTP API.
This roughly comprises the following changes:

- index target pools by job instead of scrape interval
- make targets within a pool exchangable while preserving existing
  health state for targets
- allow exchanging targets via HTTP API (PUT)
- show target lists in /status (experimental, for own debug use)
