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: Julian Wiedmann <jwi@linux.ibm.com> * 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.

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.

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`). --------- Signed-off-by: Filip Petkovski <filip.petkovsky@gmail.com> Co-authored-by: George Krajcsovits <krajorama@users.noreply.github.com> * doc: Mark `mad_over_time` as experimental (#13440) We forgot to do that in https://github.com/prometheus/prometheus/pull/13059 Signed-off-by: beorn7 <beorn@grafana.com> * Change metric label for Puppetdb from 'http' to 'puppetdb' Signed-off-by: Paulin Todev <paulin.todev@gmail.com> * mirror metrics.proto change & generate code Signed-off-by: Ziqi Zhao <zhaoziqi9146@gmail.com> * TestHeadLabelValuesWithMatchers: Add test case (#13414) Add test case to TestHeadLabelValuesWithMatchers, while fixing a couple of typos in other test cases.

He has contributed a lot of native histogram code, but more importantly, he has contributed substantially to reviewing other contributors' native histogram code, up to a point where I was merely rubberstamping the PRs he had already reviewed. I'm confident that he is ready to to be granted commit rights as outlined in the "Maintainers" section of the governance: https://prometheus.io/governance/#maintainers According to the same section of the governance, I will announce the proposed change on the developers mailing list and will give some time for lazy consensus before merging this PR.

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.

beorn7	5b53aa1108	style: Replace `else if` cascades with `switch` ... Wiser coders than myself have come to the conclusion that a `switch` statement is almost always superior to a statement that includes any `else if`. The exceptions that I have found in our codebase are just these two: * The `if else` is followed by an additional statement before the next condition (separated by a `;`). * The whole thing is within a `for` loop and `break` statements are used. In this case, using `switch` would require tagging the `for` loop, which probably tips the balance. Why are `switch` statements more readable? For one, fewer curly braces. But more importantly, the conditions all have the same alignment, so the whole thing follows the natural flow of going down a list of conditions. With `else if`, in contrast, all conditions but the first are "hidden" behind `} else if `, harder to spot and (for no good reason) presented differently from the first condition. I'm sure the aforemention wise coders can list even more reasons. In any case, I like it so much that I have found myself recommending it in code reviews. I would like to make it a habit in our code base, without making it a hard requirement that we would test on the CI. But for that, there has to be a role model, so this commit eliminates all `if else` occurrences, unless it is autogenerated code or fits one of the exceptions above.

Bryan Boreham	abd9909595	Update package storage/remote for new labels.Labels type ... `QueueManager.externalLabels` becomes a slice rather than a `Labels` so we can index into it when doing the merge operation. Note we avoid calling `Labels.Len()` in `labelProtosToLabels()`. It isn't necessary - `append()` will enlarge the buffer and we're expecting to re-use it many times. Also, we now validate protobuf input before converting to Labels. This way we can detect errors first, and we don't place unnecessary requirements on the Labels structure.

Chris Marchbanks	a11e73edda	Fix a deadlock between Batch and FlushAndShutdown (#10608) ... If FlushAndShutdown is called with a full batchQueue, and then Batch is called rather than the normal path of reading from a queue a deadlock might be encountered. Rather than having FlushAndShutdown having blocking code while holding a lock retry sending the batch every second. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	3 years ago
Chris Marchbanks	e970acb085	Fix deadlock between adding to queue and getting batch ... Do not block when trying to write a batch to the queue. This can cause appends to lock forever if the only thing reading from the queue needs the mutex to write. Instead, if batchQueue is full pop the sample that was just added from the partial batch and return false. The code doing the appending already handles retries with backoff.

Chris Marchbanks	bfb1500a38	Fix deadlock when stopping a shard (#10279) ... If a queue is stopped and one of its shards happens to hit the batch_send_deadline at the same time a deadlock can occur where stop holds the mutex and will not release it until the send is finished, but the send needs the mutex to retrieve the most recent batch. This is fixed by using a second mutex just for writing. In addition, the test I wrote exposed a case where during shutdown a batch could be sent twice due to concurrent calls to queue.Batch() and queue.FlushAndShutdown(). Protect these with a mutex as well. Signed-off-by: Chris Marchbanks <csmarchbanks@gmail.com>	3 years ago

Goutham Veeramachaneni	1af81dc5c9	Update sent timestamp when write irrecoverably fails. ... We have an alert that fires when prometheus_remote_storage_highest_timestamp_in_seconds - prometheus_remote_storage_queue_highest_sent_timestamp_seconds becomes too high. But we have an agent that fires this when the remote "rate-limits" the user. This is because prometheus_remote_storage_queue_highest_sent_timestamp_seconds doesn't get updated when the remote sends a 429. I think we should update the metrics, and the change I made makes sense. Because if the requests fails because of connectivity issues, etc. we will never exit the `sendWriteRequestWithBackoff` function. It only exits the function when there is a non-recoverable error, like a bad status code, and in that case, I think the metric needs to be updated.

Dieter Plaetinck	cda025b5b5	TSDB: demistify SeriesRefs and ChunkRefs (#9536) ... * TSDB: demistify seriesRefs and ChunkRefs The TSDB package contains many types of series and chunk references, all shrouded in uint types. Often the same uint value may actually mean one of different types, in non-obvious ways. This PR aims to clarify the code and help navigating to relevant docs, usage, etc much quicker. Concretely: * Use appropriately named types and document their semantics and relations. * Make multiplexing and demuxing of types explicit (on the boundaries between concrete implementations and generic interfaces). * Casting between different types should be free. None of the changes should have any impact on how the code runs.
