- Add Try* prefix to functions, which return bool result in order to improve readability and reduce the probability of missing check for the result returned from these functions. - Call the adjustSampleValues() only once on input samples. Previously it was called on every attempt to flush data to peristent queue. - Properly restore the initial state of WriteRequest passed to tryPushWriteRequest() before returning from this function after unsuccessful push to persistent queue. Previously a part of WriteRequest samples may be lost in such case. - Add -remoteWrite.dropSamplesOnOverload command-line flag, which can be used for dropping incoming samples instead of returning 429 Too Many Requests error to the client when -remoteWrite.disableOnDiskQueue is set and the remote storage cannot keep up with the data ingestion rate. - Add vmagent_remotewrite_samples_dropped_total metric, which counts the number of dropped samples. - Add vmagent_remotewrite_push_failures_total metric, which counts the number of unsuccessful attempts to push data to persistent queue when -remoteWrite.disableOnDiskQueue is set. - Remove vmagent_remotewrite_aggregation_metrics_dropped_total and vm_promscrape_push_samples_dropped_total metrics, because they are replaced with vmagent_remotewrite_samples_dropped_total metric. - Update 'Disabling on-disk persistence' docs at docs/vmagent.md - Update stale comments in the code Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5088 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2110
