Matt Bostock 78715e4182 Alerts template: remove silence table header
There's no corresponding table column for this table header. The
placeholder link for silences was removed in e8800730.

Accordingly, regenerate `web/ui/bindata.go` by running:

Julius Volz 3bfec97d46 Make the storage interface higher-level.
See discussion in
https://groups.google.com/forum/#!topic/prometheus-developers/bkuGbVlvQ9g

The main idea is that the user of a storage shouldn't have to deal with
fingerprints anymore, and should not need to do an individual preload
call for each metric. The storage interface needs to be made more
high-level to not expose these details.

This also makes it easier to reuse the same storage interface for remote
storages later, as fewer roundtrips are required and the fingerprint
concept doesn't work well across the network.

NOTE: this deliberately gets rid of a small optimization in the old
query Analyzer, where we dedupe instants and ranges for the same series.
This should have a minor impact, as most queries do not have multiple
selectors loading the same series (and at the same offset).

storage: improve index lookups
2016-07-20 17:38:04 +02:00
beorn7 fc6737b7fb storage: improve index lookups
tl;dr: This is not a fundamental solution to the indexing problem
(like tindex is) but it at least avoids utilizing the intersection
problem to the greatest possible amount.

In more detail:

Imagine the following query:

    nicely:aggregating:rule{job="foo",env="prod"}

While it uses a nicely aggregating recording rule (which might have a
very low cardinality), Prometheus still intersects the low number of
fingerprints for `{__name__="nicely:aggregating:rule"}` with the many
thousands of fingerprints matching `{job="foo"}` and with the millions
of fingerprints matching `{env="prod"}`. This totally innocuous query
is dead slow if the Prometheus server has a lot of time series with
the `{env="prod"}` label. Ironically, if you make the query more
complicated, it becomes blazingly fast:

    nicely:aggregating:rule{job=~"foo",env=~"prod"}

Why so? Because Prometheus only intersects with non-Equal matchers if
there are no Equal matchers. That's good in this case because it
retrieves the few fingerprints for
`{__name__="nicely:aggregating:rule"}` and then starts right ahead to
retrieve the metric for those FPs and checking individually if they
match the other matchers.

This change is generalizing the idea of when to stop intersecting FPs
and go into "retrieve metrics and check them individually against
remaining matchers" mode:

- First, sort all matchers by "expected cardinality". Matchers
  matching the empty string are always worst (and never used for
  intersections). Equal matchers are in general consider best, but by
  using some crude heuristics, we declare some better than others
  (instance labels or anything that looks like a recording rule).

- Then go through the matchers until we hit a threshold of remaining
  FPs in the intersection. This threshold is higher if we are already
  in the non-Equal matcher area as intersection is even more expensive
  here.

- Once the threshold has been reached (or we have run out of matchers
  that do not match the empty string), start with "retrieve metrics
  and check them individually against remaining matchers".

A beefy server at SoundCloud was spending 67% of its CPU time in index
lookups (fingerprintsForLabelPairs), serving mostly a dashboard that
is exclusively built with recording rules. With this change, it spends
only 35% in fingerprintsForLabelPairs. The CPU usage dropped from 26
cores to 18 cores. The median latency for query_range dropped from 14s
to 50ms(!). As expected, higher percentile latency didn't improve that
much because the new approach is _occasionally_ running into the worst
case while the old one was _systematically_ doing so. The 99th
percentile latency is now about as high as the median before (14s)
while it was almost twice as high before (26s).

beorn7 bf6201483c Improve wording on log flag comment 2016-07-20 17:32:42 +02:00
beorn7 25385aafcb Explicitly add logging flags to our custom flag set
In https://github.com/prometheus/prometheus/pull/1782 , we moved to a
custom flag set to avoid getting test flags into the main prometheus
binary. However, that removed the logging flags, too. This commit
updates the vendoring to a version of the log package that allows
adding the log flags to our flag set explicitly.
