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.

Matt T. Proud 0d2d6e9a27 Include uptime in the status console. 
In order to help corroborate whether a Prometheus instance has
flapped until meta-monitoring is in-place, we ought to provide the
instance's start time in the console to aid in diagnostics.

Julius Volz 8586c7520c Support negative graph values. 
Currently graph Y-Axes were hardcoded to start at 0. Choose the Y-scale
automatically based on the graph data instead.

Matt T. Proud 1a95406b81 Include forgotten databases.html. 2013-05-14 14:50:54 +02:00
Matt T. Proud b224251981 Simplify compaction and expose database sizes. 
This commit simplifies the way that compactions across a database's
keyspace occur due to reading the LevelDB internals. Secondarily it
introduces the database size estimation mechanisms.

Include database health and help interfaces.

Add database statistics; remove status goroutines.

This commit kills the use of Go routines to expose status throughout
the web components of Prometheus. It also dumps raw LevelDB status
on a separate /databases endpoint.

Matt Proud 7f0d816574 Schedule the background compactors to run. 
This commit introduces three background compactors, which compact
sparse samples together.

1. Older than five minutes is grouped together into chunks of 50 every 30
   minutes.

2. Older than 60 minutes is grouped together into chunks of 250 every 50
   minutes.

3. Older than one day is grouped together into chunks of 5000 every 70
   minutes.

This commit destroys the use of AppState, which makes passing
concrete state along to various serving components onerous.

Matt T. Proud 961ff26874 Fix positional flags for `cp` on Darwin. 
Unfortunately ``cp`` on Darwin regards some flags as positional and

 2013-04-24 18:51:07 +02:00
Matt T. Proud 9e02c2393a Include generated Protocol Buffer descriptor. 
The Protocol Buffer compiler supports generating a machine-readable
descriptor file encoded as a provided Protocol Buffer message type,
which can be used to decode messages that have been encoded with it
after-the-fact.  The generated descriptor also bundles in dependent
message types.

We can use this to perform forensics on old Prometheus clients, if
necessary.

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.

 2013-04-12 07:27:30 -07:00
Johannes 'fish' Ziemke 14407a076a Convert addresses pointing to localhost in status. 
Until now, targets pointing to localhost in the status view are linked to localhost, so you can't follow those links by clicking on them.
This change converts the links to point to the hostname of the prometheus server.

Before:
<a href="http://localhost:9090/metrics.json">http://localhost:9090/metrics.json</a>

After:
<a href="http://hostname-of-prometheus-server:9090/metrics.json">http://localhost:9090/metrics.json</a>

Matt T. Proud 3e97a3630d Include nascent curator scaffolding. 
The curator doesn't do anything yet; rather, this is the type
definition including the anciliary testing scaffold.

Improve Makefile and Git developer experience.

The top-level Makefile was a bit overloaded in terms of generation of
assets and their management.  This has been offloaded into separate
Makefiles.

The Git developer experience sucked due to lack of .gitignore
policies.

Also: Fix faulty skiplist naming from old merge.

- make targets within a pool exchangable while preserving existing

- allow exchanging targets via HTTP API (PUT)
- show target lists in /status (experimental, for own debug use)
