beorn7 ec08c9a391 Rework the way to communicate backpressure (AKA suspended ingestion)
This gives up on the idea to communicate throuh the Append() call (by
either not returning as it is now or returning an error as
suggested/explored elsewhere). Here I have added a Throttled() call,
which has the advantage that it can be called before a whole _batch_
of Append()'s. Scrapes will happen completely or not at all. Same for
rule group evaluations. That's a highly desired behavior (as discussed
elsewhere). The code is even simpler now as the whole ingestion buffer
could be removed.

Logging of throttled mode has been streamlined and will create at most
one message per minute.

Anders Daljord Morken 9fb65a91af Close HTTP connections on HTTP errors too.
Move defer resp.Body.Close() up to make sure it's called even when the
HTTP request returns something other than 200 or Decoder construction
fails. This avoids leaking and eventually running out of file descriptors.

Will Rouesnel 7810448dbe Add proxy_url parameter to allow specifying per-job HTTP proxy servers
Allow scrape_configs to have an optional proxy_url option which specifies
a proxy to be used for all connections to hosts in that config.

Internally this modifies the various client functions to take a *url.URL pointer
which currently must point to an HTTP proxy (but has been left open-ended to
allow the url format to be extended to support others, such as maybe SOCKS if
needed).

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

Julius Volz 267fd34156 Switch Prometheus to use github.com/prometheus/log.
This change is conceptually very simple, although the diff is large. It
switches logging from "github.com/golang/glog" to
"github.com/prometheus/log", while not actually changing any log
messages. V(1)-style logging has been changed to be log.Debug*().

Fabian Reinartz 385919a65a Avoid inter-component blocking if ingestion/scraping blocks.
Appending to the storage can block for a long time. Timing out
scrapes can also cause longer blocks. This commit avoids that those

Also the Target interface was removed.

beorn7 fa1935a644 Remove /api/targets call and do not show job and instance labels on status.
/api/targets was undocumented and never used and also broken.

Showing instance and job labels on the status page (next to targets)
does not make sense as those labels are set in an obvious way.

Also add a doc comment to TargetStateToClass.

beorn7 be11cb2b07 Remove the sample ingestion channel.
The one central sample ingestion channel has caused a variety of
trouble. This commit removes it. Targets and rule evaluation call an
Append method directly now. To incorporate multiple storage backends
(like OpenTSDB), storage.Tee forks the Append into two different
appenders.

Note that the tsdb queue manager had its own queue anyway. It was a
queue after a queue... Much queue, so overhead...

Targets have their own little buffer (implemented as a channel) to
avoid stalling during an http scrape. But a new scrape will only be
started once the old one is fully ingested.

The contraption of three pipelined ingesters was removed. A Target is
an ingester itself now. Despite more logic in Target, things should be
less confusing now.

Also, remove lint and vet warnings in ast.go.
2015-03-15 14:08:22 +01:00
Julius Volz 140eede5e0 Rename UNREACHABLE to UNHEALTHY.
The current wording suggests that a target is not reachable at all,
although it might also get set when the target was reachable, but there
was some other error during the scrape (invalid headers or invalid
scrape content). UNHEALTHY is a more general wording that includes all
these cases.

For consistency, ALIVE is also renamed to HEALTHY.

beorn7 0f191629c6 Next try to deal with backed-up ingestion.
This is now not even trying to throttle in a benign way, but creates a
fully-fledged error. Advantage: It shows up very visible on the status
page. Disadvantage: The server does not really adjusts to a lower
scraping rate. However, if your ingestion backs up, you are in a very
irregulare state, I'd say it _should_ be considered an error and not
dealt with in a more graceful way.

In different news: I'll work on optimizing ingestion so that we will
not as easily run into that situation in the first place.

The simple algorithm applied here will increase the actual interval
incrementally, whenever and as long as the scrape itself takes longer
than the configured interval. Once it takes shorter again, the actual
interval will iteratively decrease again.

Bjoern Rabenstein 1909686789 Make metrics exported by the Prometheus server itself more consistent.
- Always spell out the time unit (e.g. milliseconds instead of ms).

- Remove "_total" from the names of metrics that are not counters.

- Make use of the "Namespace" and "Subsystem" fields in the options.

- Removed the "capacity" facet from all metrics about channels/queues.
  These are all fixed via command line flags and will never change
  during the runtime of a process. Also, they should not be part of
  the same metric family. I have added separate metrics for the
  capacity of queues as convenience. (They will never change and are
  only set once.)

- I left "metric_disk_latency_microseconds" unchanged, although that
  metric measures the latency of the storage device, even if it is not
  a spinning disk. "SSD" is read by many as "solid state disk", so
  it's not too far off. (It should be "solid state drive", of course,
  but "metric_drive_latency_microseconds" is probably confusing.)

- Brian suggested to not mix "failure" and "success" outcome in the
  same metric family (distinguished by labels). For now, I left it as
  it is. We are touching some bigger issue here, especially as other
  parts in the Prometheus ecosystem are following the same
  principle. We still need to come to terms here and then change
  things consistently everywhere.

Julius Volz 740d448983 Use custom timestamp type for sample timestamps and related code.
So far we've been using Go's native time.Time for anything related to sample
timestamps. Since the range of time.Time is much bigger than what we need, this
has created two problems:

- there could be time.Time values which were out of the range/precision of the
  time type that we persist to disk, therefore causing incorrectly ordered keys.
  One bug caused by this was:

  https://github.com/prometheus/prometheus/issues/367

  It would be good to use a timestamp type that's more closely aligned with
  what the underlying storage supports.

- sizeof(time.Time) is 192, while Prometheus should be ok with a single 64-bit
  Unix timestamp (possibly even a 32-bit one). Since we store samples in large
  numbers, this seriously affects memory usage. Furthermore, copying/working
  with the data will be faster if it's smaller.

*MEMORY USAGE RESULTS*
Initial memory usage comparisons for a running Prometheus with 1 timeseries and
100,000 samples show roughly a 13% decrease in total (VIRT) memory usage. In my
tests, this advantage for some reason decreased a bit the more samples the
timeseries had (to 5-7% for millions of samples). This I can't fully explain,
but perhaps garbage collection issues were involved.

*WHEN TO USE THE NEW TIMESTAMP TYPE*
The new clientmodel.Timestamp type should be used whenever time
calculations are either directly or indirectly related to sample
timestamps.

For example:
- the timestamp of a sample itself
- all kinds of watermarks
- anything that may become or is compared to a sample timestamp (like the timestamp
  passed into Target.Scrape()).

When to still use time.Time:
- for measuring durations/times not related to sample timestamps, like duration
  telemetry exporting, timers that indicate how frequently to execute some
  action, etc.

*NOTE ON OPERATOR OPTIMIZATION TESTS*
We don't use operator optimization code anymore, but it still lives in
the code as dead code. It still has tests, but I couldn't get all of them to
pass with the new timestamp format. I commented out the failing cases for now,
but we should probably remove the dead code soon. I just didn't want to do that
in the same change as this.

Matt T. Proud e20e6980e9 Completely extract response payload for decoding.
This commit forces the extraction framework to read the entire response payload
into a buffer before attempting to decode it, for the underlying Protocol Buffer
message readers do not block on partial messages.

Bernerd Schaefer 3929582892 Target uses HTTP transport with deadlines
Instead of externally handling timeouts when scraping a target, we set
timeouts on the HTTP connection. This ensures that we don't leak
goroutines on timeouts.

Julius Volz a1ba23038e Fix scrape timestamps to reduce sample time jitter.
We're currently timestamping samples with the time at the end of a scrape
iteration. It makes more sense to use a timestamp from the beginning of the
scrape for two reasons:

a) this time is more relevant to the scraped values than the time at the
   end of the HTTP-GET + JSON decoding work.
b) it reduces sample timestamp jitter if we measure at the beginning, and
   not at the completion of a scrape.

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>
