* 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.

* tsdb: shrink txRing with smaller integers

4 billion active transactions ought to be enough for anyone.

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.

* Get VM Scale Set NIC (#13283)

Calling `*armnetwork.InterfacesClient.Get()` doesn't work for Scale Set
VM NIC, because these use a different Resource ID format.

Use `*armnetwork.InterfacesClient.GetVirtualMachineScaleSetNetworkInterface()`
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.

TSDB: Simplify OOO Select by copying the head chunk (#14396)
Instead of carrying around extra fields in `Meta` structs which let us
approximate what was in the chunk at the time, take a copy of the chunk.

This simplifies lots of code, and lets us correct a couple of tests which
were embedding the wrong answer.

We can also remove boundedIterator, which was only used to constrain
the OOO head chunk.

Pass affected labels to MemPostings.Delete() (#14307)
* Pass affected labels to MemPostings.Delete

As suggested by @bboreham, we can track the labels of the deleted series
and avoid iterating through all the label/value combinations.

This looks much faster on the MemPostings.Delete call. We don't have a
benchmark on stripeSeries.gc() where we'll pay the price of iterating
the labels of each one of the deleted series.

Change LabelValuesFor() to accept index.Postings (#14280)
The only call we have to LabelValuesFor() has an index.Postings, and we
expand it to pass to this method, which will iterate over the values.

That's a waste of resources: we can iterate on the index.Postings
directly.

If there's any downstream implementation that has a slice of series,
they can always do an index.ListPostings from them: doing that is
cheaper than expanding an abstract index.Postings.

MemPostings.PostingsForLabelMatching(): don't hold the mutex while matching (#14286)
* MemPostings.PostingsForLabelMatching: let mutex go

This changes the `MemPostings.PostingsForLabelMatching` implementation
to stop holding the read mutex while matching the label values.

We've seen that this method can be slow when the matcher is expensive,
that's why we even added a context expiration check.

However, there are critical process that might be waiting on this mutex:
writes (adding new series) and compaction (deleting the
garbage-collected ones), so we should avoid holding it for a long period
of time.

Given that we've copied the values to a slice anyway, there's no need to
hold the lock while matching.

MemPostings.Delete(): reduce locking/unlocking (#13286)
* MemPostings: reduce locking/unlocking

MemPostings.Delete is called from Head.gc(), i.e. it gets the IDs of the
series that have churned.

I'd assume that many label values aren't affected by that churn at all,
so it doesn't make sense to touch the lock while checking them.

headIndexReader.LabelNamesFor: skip not found series
It's quite common during the compaction cycle to hold series IDs for
series that aren't in the TSDB head anymore.

We shouldn't fail if that happens, as the caller has no way to figure
out which one of the IDs doesn't exist.

Check context every 128 labels instead of 100 (#14118)
Follow up on https://github.com/prometheus/prometheus/pull/14096

As promised, I bring a benchmark, which shows a very small improvement
if context is checked every 128 iterations of label instead of every
100.

It's much easier for a computer to check modulo 128 than modulo 100.
This is a very small 0-2% improvement but I'd say this is one of the
hottest paths of the app so this is still relevant.

Add method `PostingsForLabelMatching` to `tsdb.IndexReader`, to obtain postings for labels with a certain name and values accepted by a provided callback, and use it from `tsdb.PostingsForMatchers`.
The intention is to optimize regexp matcher paths, especially not having to load all label values before matching on them.

Plus tests, and refactor some `tsdb/index.Reader` methods.

Benchmarking shows memory reduction up to ~100%, and speedup of up to ~50%.

Stop compactions if there's a block to write (#13754)
* Stop compactions if there's a block to write

db.Compact() checks if there's a block to write with HEAD chunks before calling db.compactBlocks().
This is to ensure that if we need to write a block then it happens ASAP, otherwise memory usage might keep growing.

But what can also happen is that we don't need to write any block, we start db.compactBlocks(),
compaction takes hours, and in the meantime HEAD needs to write out chunks to a block.

This can be especially problematic if, for example, you run Thanos sidecar that's uploading block,
which requires that compactions are disabled. Then you disable Thanos sidecar and re-enable compactions.
When db.compactBlocks() is finally called it might have a huge number of blocks to compact, which might
take a very long time, during which HEAD cannot write out chunks to a new block.
In such case memory usage will keep growing until either:
- compactions are finally finished and HEAD can write a block
- we run out of memory and Prometheus gets OOM-killed

This change adds a check for pending HEAD block writes inside db.compactBlocks(), so that
we bail out early if there are still compactions to run, but we also need to write a new
block.

Also add a test for compactBlocks.

relied on the default values for min and max time and integer overflow
when they were checked in `Head.compactable()`. The check in
`Head.compactable()` effectively did `math.MinInt64 - math.MaxInt64`
which overflowed and wrapped to `1`. Since `1` is less than `1.5`
times the chunk range, compaction did not happen. This was the correct
behavior but relying on overflow wrapping is surprising.

This change add a method for checking if the min and max time for the
head is unset and uses it to short-circuit compaction in that case.
It also replaces several explicit checks for the default value to
determine if the head has not yet had any samples added.

Marco Pracucci 501bc6419e
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.

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`).

Fix reusing float histograms
In https://github.com/prometheus/prometheus/pull/13276 we started reusing float histogram objects to reduce allocations in PromQL.
That PR introduces a bug where histogram pointers gets copied to the beginning of the histograms slice,
but are still kept in the end of the slice. When a new histogram is read into the last element,
it can overwrite a previous element because the pointer is the same.

This commit fixes the issue by moving outdated points to the end of the slice
so that we don't end up with duplicate pointers in the same buffer. In other words,
the slice gets rotated so that old objects can get reused.

Bryan Boreham ab3a47b489 postings: use Loser Tree for merge
It's faster.

Note change to test - instead of requiring that the data structure is
identical to `EmptyPostings()`, check that calling `Next()` returns
false, which implies it was empty.

Also the check for context cancellation during initialization was
removed. Initialization should be a small portion of the work done
during merge, so it's not worth plumbing a context argument through.

Enable reusing memory when converting between histogram types
The 'ToFloat' method on integer histograms currently allocates new memory
each time it is called.

This commit adds an optional *FloatHistogram parameter that can be used
to reuse span and bucket slices. It is up to the caller to make sure the
input float histogram is not used anymore after the call.

Change ChunkReader.Chunk() to ChunkOrIterable()
The ChunkReader interface's Chunk() has been changed to ChunkOrIterable(). 

This is a precursor to OOO native histogram support - with OOO native histograms, the chunks.Meta passed to Chunk() can result in multiple chunks being returned rather than just a single chunk (e.g. if oooMergedChunk has a counter reset in the middle). 

To support this, ChunkOrIterable() requires either a single chunk or an iterable to be returned. If an iterable is returned, the caller has the responsibility of converting the samples from the iterable into possibly multiple chunks. The OOOHeadChunkReader now returns an iterable rather than a chunk to prepare for the native histograms case. Also as a beneficial side effect, oooMergedChunk and boundedChunk has been simplified as they only need to implement the Iterable interface now, not the full Chunk interface.

When debugging an issue, seeing an ULID like

helpful, so I propose to make them readable in their ULID string

Fix error on ingesting out-of-order exemplars (#13021)
Fix and improve ingesting exemplars for native histograms.

See code comment for a detailed explanation of the algorithm.

Note that this changes the current behavior for all kind of samples slightly: We now allow exemplars with the same timestamp as during the last scrape if the value or the labels have changed.

Also note that we now do not ingest exemplars without timestamps for native histograms anymore.
