I think the need here is pretty obvious from the context, though I think it's easy to imagine preferring this to be a change to the existing processor. I raised as a new one as I thought it might make existing behavior cleaner to retain. **Link to tracking Issue:** As above this is a bit of a premature PR since I intended to raise as an issue, and thus there isn't one, but I think it's easy enough to deal with here so leaving open for now and have learned GitHub's ways for the future (I rarely use github). **Testing:** New module so associated tests are added showing all relevant behavior, and passing. **Documentation:** Updated README and example config --------- Signed-off-by: dependabot[bot] <support@github.com> Co-authored-by: dependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com> * [googlemanagedprometheusexporter] Clarify support status of this exporter (open-telemetry#28863) * Link to related GCP docs * Clarify mention of "traces" * Drop mention of PromQL support as a difference from `googlecloud` exporter * [filelogreceiver]: Add ability to sort by mtime (open-telemetry#28850) **Description:** <Describe what has changed.> * Adds a new `mtime` sort type, which will sort files by their modified time * Add a feature gate for `mtime` sort type An optional follow-up performance improvement may be made here, to have the finder return fs.DirEntry directly to query the mtime without making an extra call to os.Stat for each file. **Link to tracking Issue:** open-telemetry#27812 **Testing:** * Added unit tests for new functionality **Documentation:** * Added new `mode` parameter to filelogreceiver docs * [pkg/traslator] move skywalking_to_traces into pkg/translator (open-telemetry#28814) **Description:** A part of open-telemetry#28693 <!--Ex.

By creating one exporter per worker we can now increase the number of metrics being send to the backend. Fixes open-telemetry#26709 - Units tests pass - Ran local load tests with different configurations ## Before code change Generate metrics: ``` telemetrygen metrics \ --metric-type Sum \ --duration "60s" \ --rate "0" \ --workers "10" \ --otlp-http=false \ --otlp-endpoint <HOSTNAME> \ --otlp-attributes "service.name"=\"telemetrygen\" ``` Output: ``` metrics generated {"worker": 8, "metrics": 139} metrics generated {"worker": 0, "metrics": 139} metrics generated {"worker": 9, "metrics": 141} metrics generated {"worker": 4, "metrics": 140} metrics generated {"worker": 2, "metrics": 140} metrics generated {"worker": 3, "metrics": 140} metrics generated {"worker": 7, "metrics": 140} metrics generated {"worker": 5, "metrics": 140} metrics generated {"worker": 1, "metrics": 140} metrics generated {"worker": 6, "metrics": 140} ``` ## After code change ``` telemetrygen metrics \ --metric-type Sum \ --duration "60s" \ --rate "0" \ --workers "10" \ --otlp-http=false \ --otlp-endpoint <HOSTNAME> \ --otlp-attributes "service.name"=\"telemetrygen\" ``` Output: ``` metrics generated {"worker": 6, "metrics": 1292} metrics generated {"worker": 3, "metrics": 1277} metrics generated {"worker": 5, "metrics": 1272} metrics generated {"worker": 8, "metrics": 1251} metrics generated {"worker": 9, "metrics": 1241} metrics generated {"worker": 4, "metrics": 1227} metrics generated {"worker": 0, "metrics": 1212} metrics generated {"worker": 2, "metrics": 1201} metrics generated {"worker": 1, "metrics": 1333} metrics generated {"worker": 7, "metrics": 1363} ``` By adding more workers you can now export more metrics and use `telemetrygen` better for load testing use cases. With the code change I can now utilize my CPU better for load tests. When adding 200 workers to the above config the CPU usage can go above 80%. Before that CPU usage would be around 1% with 200 workers.  --------- Co-authored-by: Alex Boten <aboten@lightstep.com> * [scraper/processscraper] Fix TestScrapeMetrics_MuteErrorFlags failures on windows and darwin (open-telemetry#28864) **Description:** There were some issues related to how `mock.On` works.

Fixing a bug - Describe the bug and how this fixes the issue. Ex. Adding a feature - Explain what this achieves.--> This pull request introduces the ability to configure the Azure Monitor Exporter using a connection string, aligning the exporter configuration with Azure Monitor's recommended practices. The current implementation requires users to set the instrumentation key directly, which will soon be deprecated in favor of using the connection string. **Changes Made:** 1. Configuration Update: Modified the `Config` struct and related configuration parsing logic to support a `ConnectionString` field. 2. Parsing Logic: Implemented functionality to parse the connection string and extract necessary details, such as `InstrumentationKey` and `IngestionEndpoint`. 3. Updated Tests: Revised existing tests and added new ones to ensure coverage of the new configuration option. **Benefits:** * Streamlines the configuration process for end-users. * Aligns with Azure Monitor's best practices and recommended configuration approach. * Paves the way for the upcoming deprecation of direct instrumentation key configuration. **Backwards Compatibility:** This update maintains full backwards compatibility. Users currently utilizing the instrumentation key for configuration can continue to do so but are advised to transition to using the connection string. **To-Do** * Documentation Update in a follow up PR * Deprecation Notice: A future update will introduce a deprecation warning for users still configuring the exporter with the instrumentation key, encouraging them to switch to using a connection string. * Add support for `EndpointSuffix` in connection string - https://learn.microsoft.com/en-us/azure/azure-monitor/app/sdk-connection-string?tabs=dotnet5#connection-string-with-an-endpoint-suffix **Link to tracking Issue:** <Issue number if applicable> open-telemetry#28853 **Testing:** <Describe what testing was performed and which tests were added.> Conducted comprehensive testing, including unit tests, to validate that the new configuration option works as expected and does not introduce regressions. All tests are currently passing. ``` [Wed Nov 1 12:53:42 PDT 2023] --------- Transmitting 27 items --------- [Wed Nov 1 12:53:43 PDT 2023] Telemetry transmitted in 331.926261ms [Wed Nov 1 12:53:43 PDT 2023] Response: 200 [Wed Nov 1 12:53:43 PDT 2023] Items accepted/received: 27/27 [Wed Nov 1 12:53:53 PDT 2023] --------- Transmitting 30 items --------- [Wed Nov 1 12:53:53 PDT 2023] Telemetry transmitted in 73.171392ms [Wed Nov 1 12:53:53 PDT 2023] Response: 200 [Wed Nov 1 12:53:53 PDT 2023] Items accepted/received: 30/30 [Wed Nov 1 12:54:04 PDT 2023] --------- Transmitting 27 items --------- [Wed Nov 1 12:54:04 PDT 2023] Telemetry transmitted in 68.037724ms [Wed Nov 1 12:54:04 PDT 2023] Response: 200 [Wed Nov 1 12:54:04 PDT 2023] Items accepted/received: 27/27 ``` **Documentation:** <Describe the documentation added.> TODO, in a follow up PR. * [exporter/awsxray] Add aws sdk http error events to x-ray subsegment and strip prefix `AWS.SDK.` from aws remote service name (open-telemetry#27232) **Description:** <Describe what has changed.> <!--Ex.

Part of open-telemetry#28647 Signed-off-by: Alex Boten <aboten@lightstep.com> * Make replication stats return whole number (open-telemetry#28824) **Description:** I failed to reproduce []uint8 to int64 conversion but I was able to repro float64 to int64 conversion error. Different types may be due to different versions or values reported. The fix is forcing query to retrieve integer values. While this may seem like most obvious fix I'm not really aligned with it. What query is returning for is a lag as a decimal number (whole part is seconds) by forcing this to return just an int we kind of losing precision. `0.4s` are reported as `0` while it is `400ms`. My proposal here would consists of 2 options. First one is change reporting in a way that what we report is in fact time-span in `ms`. This could most likely be considered breaking. Second option (I'm more in favor of) is to change the type of what is reported (from int to float). This way unit is intact and does not break possible visualizations, but we gain precision and won't lose data. My first issue here so I wanted to get some feedback first before publishing something unreasonable. _EDIT_ Went with the option of deprecating metrics with second precision (still fixing conversion failures) and introducing alternative to these metrics with `_ms` suffix in name and millisecond precision. Old metrics are now behind a featuregate which is enabled by default for now. **Link to tracking Issue:** open-telemetry#26714 **Testing:** Setting up replicated postgres instances and testing method against this deployment. **Documentation:** - --------- Co-authored-by: Daniel Jaglowski <jaglows3@gmail.com> * Retract googlecloud exporter releases that don't have logging (open-telemetry#28884) **Description:** Logging was broken after open-telemetry#25900 (released in v0.84.0).

If we manually modify the code(as shown below) and use invalid kafka broker, such as `localhost:invalid-port`, the same error as shown in the issue may occur. ``` // receiver/kafkametricsreceiver/integration_test.go scraperinttest.WithCustomConfig( func(t *testing.T, cfg component.Config, ci *scraperinttest.ContainerInfo) { rCfg := cfg.(*Config) rCfg.CollectionInterval = 5 * time.Second rCfg.Brokers = []string{"localhost:invalid-port"} rCfg.Scrapers = []string{"brokers", "consumers", "topics"} }), ``` 2. If we execute the test commands **sequentially** , it seems that the execution results are all correct. ``` # all result are correct for i in {1..100}; do echo "Run $i"; ./${CMD} ; done ``` 3. If we execute the commands in **parallel** end with **`&`**, sometimes the error shown in the issue may occur. ``` # sometimes result occur error for i in {1..20}; do echo "Run $i"; ./${CMD} &; done ``` **Inference:** I have found that duplicate container networks and container names can cause container creation to fail or result in successfully created containers with unavailable ports, which may lead to issues similar to the one shown. **Additional information:** Since Kafka's startup relies on ZooKeeper (which waits for the default `zookeeper.connection.timeout.ms=18000`), if Kafka starts first and ZooKeeper fails to start properly after the timeout duration, it will cause the Kafka container to fail to start correctly. I found the issue testcontainers/testcontainers-go#1791 wants to support that. **Documentation:** --------- Signed-off-by: sakulali <sakulali@126.com> * [chore][processort/tailsamplingprocessor] Limit concurrency for certain tests (flay test on Windows runners) (open-telemetry#29014) **Description:** Limit number of goroutines started during `processor/tailsamplingprocessor` tests.

Udp-receiver reuses the same buffer when each packet is processed. While that's working fine when running it without async config, it cause a significant amount of duplicate packets and corrupted packets being sent downstream. The reader-async thread is reading a packet from the udp port into the buffer, places that buffer in the channel, and reads another packet into the same buffer and pushes it to the channel. Let's say that the processor-async thread was a bit slow, so it only tries to read from the channel after the 2 items were placed in the channel. In that case, the processor thread will read 2 items from the channel, but it will be the same 2nd packet (since the 1st one was overwritten). In some cases, it seems the processor is reading a corrupted buffer (since the reader is currently writing into it). We can't fix it by having the reader allocate a new buffer before each time it reads a packet from the udp port, since that hurts performance significantly (reducing it up to ~50%). Instead, use a pool so the buffers are reused. Before reading a packet, the reader get a buffer from the pool. The processor returns it back to the pool after it has been successfully processed **Link to tracking Issue:** 27613 **Testing:** Ran existing unitests.

…lushing (#32210) **Description:** Discard counter span metric exemplars after flushing to avoid unbounded memory growth when exemplars are enabled. This is needed because #28671 added exemplars to counter span metrics, but they are not removed after each flush interval like they are for histogram span metrics. Note: this may change behaviour if using the undocumented `exemplars.max_per_data_point` configuration option, since exemplars would no longer be accumulated up until that count. However, i'm unclear on the value of that feature since there's no mechanism to replace old exemplars with newer ones once the maximum is reached. Maybe a follow-up enhancement is only discarding exemplars once the maximum is reached, or using a circular buffer to replace them. That could be useful for pull-based exporters like `prometheusexporter`, as retaining exemplars for longer would decrease the chance of them getting discarded before being scraped. **Link to tracking Issue:** Closes #31683 **Testing:** - Unit tests - Running the collector and setting a breakpoint to verify the exemplars are being cleared in-between flushes. Before the change I could see the exemplar count continually growing **Documentation:** <Describe the documentation added.> Updated the documentation to mention that exemplars are added to all span metrics. Also mentioned when they are discarded
