🚀 New components 🚀

• alertmanagerexporter: Add Alertmanager exporter implementation and tests (#23569)

  • receiver.jaegerreceiver.replaceThriftWithProto

• awsemfexporter/awscloudwatchlogsexporter: Add component name to user agent header for outgoing put log even requests (#29595)

• elasticsearchexporter: Logstash format compatibility. Traces or Logs data can be written into an index in logstash format. (#29624)

• extension/opampextension: Implement extension.NotifyConfig to be notified of the Collector's effective config and report it to the OpAMP server. (#27293)

• receiver/influxdbreceiver: Endpoint /ping added to enhance compatibility with third party products (#29594)

• kafkareceiver: Add the ability to consume logs from Azure Diagnostic Settings streamed through Event Hubs using the Kafka API. (#18210)

• resourcedetectionprocessor: Add detection of host.ip to system detector. (#24450)

• resourcedetectionprocessor: Add detection of host.mac to system detector. (#29587)

• pkg/ottl: Add silent ErrorMode to allow disabling logging of errors that are ignored. (#29710)

• postgresqlreceiver: Add config property for excluding specific databases from scraping (#29605)

• statsdreceiver: Add support for 'simple' tags that do not have a defined value, to accommodate DogStatsD metrics that may utilize these. (#29012)
  This functionality is gated behind a new enable_simple_tags config boolean, as it is not part of the StatsD spec.

🧰 Bug fixes 🧰

• exporter/prometheusremotewrite: prometheusremotewrite exporter fix created metrics missing timestamp (#24915)

• connector/spanmetrics: Fix memory leak when the cumulative temporality is used. (#27654)

• awscontainerinsightreceiver: Filter terminated pods from node request metrics (#27262)

• clickhouseexporter: Fix regression error introduced in #29095 (#29573)

• prometheusexporter: Fix panic when exporter mutates data (#29574)

• splunkhecexporter: Do not send null event field values in HEC events. Replace null values with an empty string. (#29551)

• k8sobjectsreceiver: fix k8sobjects receiver fails when some unrelated Kubernetes API is down (#29706)

• resourcedetectionprocessor: Change type of host.cpu.model.id and host.cpu.model.family from int to string. (#29025)

  • Disable the processor.resourcedetection.hostCPUModelAndFamilyAsString feature gate to get the old behavior.

• Fix problem where checkpoints could be lost when collector is shutdown abruptly: filelogreceiver (#29609, #29491)

• googlecloudspannerreceiver: Google Cloud Spanner Receiver currently generates an exception and exits if it attempts to read data from a database that doesn't exist. However it's normal for a single receiver to poll multiple databases, so this is not graceful failure. This PR makes a change to gracefully generate an error in case of an unreadable missing database and then continue reading other databases.. (#26732)

• pkg/stanza: Allow key_value_parser to parse values that contain the delimiter string. (#29629)
