beorn7 a6fa8a471c docs: Correct and clarify histogram bucket and resolution limits
Previously, the config doc suggested that scrapes are simply failed if
the bucket limit is exceeded. However, instead Prometheus first
attempts to reduce the resolution. This will succeed in almost all
non-pathological cases. However, in the rare case that it doesn't, the
scrape will be failed after all.

For the resolution limit AKA `native_histogram_min_bucket_factor`, the
logic is a bit different. Once the highest factor, i.e. schema -4, is
reached, the scrape will still succeed.

* remote write 2.0: sync with `main` branch (#13510)

* consoles: exclude iowait and steal from CPU Utilisation

'iowait' and 'steal' indicate specific idle/wait states, which shouldn't
be counted into CPU Utilisation. Also see
https://github.com/prometheus-operator/kube-prometheus/pull/796 and
https://github.com/kubernetes-monitoring/kubernetes-mixin/pull/667.

Per the iostat man page:

%idle
    Show the percentage of time that the CPU or CPUs were idle and the
    system did not have an outstanding disk I/O request.

%iowait
     Show the percentage of time that the CPU or CPUs were idle during
     which the system had an outstanding disk I/O request.

%steal
     Show the percentage of time spent in involuntary wait by the
     virtual CPU or CPUs while the hypervisor was servicing another
     virtual processor.

Signed-off-by: Bryan Boreham <bjboreham@gmail.com>

* tsdb: create isolation transaction slice on demand

When Prometheus restarts it creates every series read in from the WAL,
but many of those series will be finished, and never receive any more
samples. By defering allocation of the txRing slice to when it is first
needed, we save 32 bytes per stale series.

Calling `*armnetwork.InterfacesClient.Get()` doesn't work for Scale Set

instead.  This needs both the scale set name and the instance ID, so
add an `InstanceID` field to the `virtualMachine` struct.  `InstanceID`
is empty for a VM that isn't a ScaleSetVM.

* fix(discovery): allow requireUpdate util to timeout in discovery/file/file_test.go.

The loop ran indefinitely if the condition isn't met.

Before, each iteration created a new timer channel which was always outpaced by
the other timer channel with smaller duration.

minor detail: There was a memory leak: resources of the ~10 previous timers were
constantly kept. With the fix, we may keep the resources of one timer around for defaultWait
but this isn't worth the changes to make it right.

We would like to experiment with a different postings encoding format in
Thanos so in this change I am proposing adding another argument to
`NewWriter` which would allow users to change the format if needed.
Also, wire the leveled compactor so that it would be possible to change
the format there too.

* storage: skip merging when no remote storage configured

Prometheus is hard-coded to use a fanout storage between TSDB and
a remote storage which by default is empty.
This change detects the empty storage and skips merging between
result sets, which would make `Select()` sort results.

Bottom line: we skip a sort unless there really is some remote storage
configured.

* Optimize histogram iterators (#13340)

Optimize histogram iterators

Histogram iterators allocate new objects in the AtHistogram and
AtFloatHistogram methods, which makes calculating rates over long
ranges expensive.

In #13215 we allowed an existing object to be reused
when converting an integer histogram to a float histogram. This commit follows
the same idea and allows injecting an existing object in the AtHistogram and
AtFloatHistogram methods. When the injected value is nil, iterators allocate
new histograms, otherwise they populate and return the injected object.

The commit also adds a CopyTo method to Histogram and FloatHistogram which
is used in the BufferedIterator to overwrite items in the ring instead of making
new copies.

Note that a specialized HPoint pool is needed for all of this to work 
(`matrixSelectorHPool`).

* Labels: Add DropMetricName function, used in PromQL (#13446)

This function is called very frequently when executing PromQL functions,
and we can do it much more efficiently inside Labels.

In the common case that `__name__` comes first in the labels, we simply
re-point to start at the next label, which is nearly free.

`DropMetricName` is now so cheap I removed the cache - benchmarks show
everything still goes faster.

is ready to to be granted commit rights as outlined in the

how it is done for rate, sum_over_time and others.

* Add ShardedPostings() support to TSDB (#10421)

This PR is a reference implementation of the proposal described in #10420.

In addition to what described in #10420, in this PR I've introduced labels.StableHash(). The idea is to offer an hashing function which doesn't change over time, and that's used by query sharding in order to get a stable behaviour over time. The implementation of labels.StableHash() is the hashing function used by Prometheus before stringlabels, and what's used by Grafana Mimir for query sharding (because built before stringlabels was a thing).

Follow up work
As mentioned in #10420, if this PR is accepted I'm also open to upload another foundamental piece used by Grafana Mimir query sharding to accelerate the query execution: an optional, configurable and fast in-memory cache for the series hashes.

parameter added in 1.14.x. This parameter grants the operator more
flexibility to do server-side filtering of the Catalog, before
Prometheus subscribes for updates. Operators can use this to improve
both the performance of Prometheus's Consul SD and reduce the impact of
enumerating large catalogs.

Łukasz Mierzwa 870627fbed Add enable_compression scrape config option
Currently Prometheus will always request gzip compression from the target when sending scrape requests.
HTTP compression does reduce the amount of bytes sent over the wire and so is often desirable.
The downside of compression is that it requires extra resources - cpu & memory.

This also affects the resource usage on the target since it has to compress the response
before sending it to Prometheus.

This change adds a new option to the scrape job configuration block: enable_compression.
The default is true so it remains the same as current Prometheus behaviour.

Setting this option to false allows users to disable compression between Prometheus
and the scraped target, which will require more bandwidth but it lowers the resource
usage of both Prometheus and the target.

Fixes #12319.

scraping: limit detail on dropped targets, to save memory (#12647)
It's possible (quite common on Kubernetes) to have a service discovery
return thousands of targets then drop most of them in relabel rules.
The main place this data is used is to display in the web UI, where
you don't want thousands of lines of display.

The new limit is `keep_dropped_targets`, which defaults to 0
for backwards-compatibility.

Adds a new label to include the ID of the image that an instance is

instances using a certain image as that image includes some exporter.

Sometimes the image information isn't available, such as when the image
is private and the user doesn't have the roles required to see it. In
those cases we just don't set the label, as the rest of the information
from the discovery provider can still be used.

beorn7 9e500345f3 textparse/scrape: Add option to scrape both classic and native histograms
So far, if a target exposes a histogram with both classic and native
buckets, a native-histogram enabled Prometheus would ignore the
classic buckets. With the new scrape config option
`scrape_classic_histograms` set, both buckets will be ingested,
creating all the series of a classic histogram in parallel to the
native histogram series. For example, a histogram `foo` would create a
native histogram series `foo` and classic series called `foo_sum`,
`foo_count`, and `foo_bucket`.

This feature can be used in a migration strategy from classic to
native histograms, where it is desired to have a transition period
during which both native and classic histograms are present.

Note that two bugs in classic histogram parsing were found and fixed
as a byproduct of testing the new feature:

1. Series created from classic _gauge_ histograms didn't get the
   _sum/_count/_bucket prefix set.
2. Values of classic _float_ histograms weren't parsed properly.

Julien Pivotto ce55e5074d Add 'keep_firing_for' field to alerting rules
This commit adds a new 'keep_firing_for' field to Prometheus alerting
rules. The 'resolve_delay' field specifies the minimum amount of time
that an alert should remain firing, even if the expression does not
return any results.

This feature was discussed at a previous dev summit, and it was
determined that a feature like this would be useful in order to allow
the expression time to stabilize and prevent confusing resolved messages
from being propagated through Alertmanager.

This approach is simpler than having two PromQL queries, as was
sometimes discussed, and it should be easy to implement.

This commit does not include tests for the 'resolve_delay' field.  This
is intentional, as the purpose of this commit is to gather comments on
the proposed design of the 'resolve_delay' field before implementing
tests. Once the design of the 'resolve_delay' field has been finalized,
a follow-up commit will be submitted with tests."

Update example rules file to be valid with the default scrape config (#11692)
* Update docs example rules for default config

The prometheus download includes a default config to scrape itself.
This self-scraping prometheus doesn't include any metric named as
`http_inprogress_requests`, but does include one named
`prometheus_http_requests_total`.
Updating this example rule in the docs to one which can be used
out-of-the-box with the default download would be a nice improvement.
