Service metrics

Metric name Type, unit	Description Labels
`queue.messages.client_processing_duration_milliseconds` `DGAUGE`, milliseconds	Message processing time spent by the recipient.
`queue.messages.deduplicated_count_per_second` `DGAUGE`, messages/s	Message deduplication frequency shows the number of messages processed a certain number of times during the above-mentioned period, e.g. how many messages were processed once, how many were processed twice, etc. This metric allows you to determine excessive processing of repeating messages.
`queue.messages.deleted_count_per_second` `DGAUGE`, messages/s	Message dequeuing frequency.
`queue.messages.empty_receive_attempts_count_per_second` `DGAUGE`, attempts/s	Number of detected attempts to obtain an empty message per second.
`queue.messages.inflight_count` `DGAUGE`, number	Number of messages received by their recipients but not dequeued (that are still within the visibility timeout window).
`queue.messages.oldest_age_milliseconds` `DGAUGE`, milliseconds	Storage time of the earliest message in the queue. The metric name is obsolete and its `milliseconds` component does not reflect the current units of measure. Currently, the metric is measured in seconds (`s`).
`queue.messages.purged_count_per_second` `DGAUGE`, messages/s	Frequency of message deletion using the PurgeQueue method.
`queue.messages.receive_attempts_count_rate` `DGAUGE`, number	Number of attempts to receive messages from the queue.
`queue.messages.received_bytes_per_second` `DGAUGE`, bytes/s	Total size of messages received from the queue per second.
`queue.messages.received_count_per_second` `DGAUGE`, messages/s	Number of messages received from the queue per second.
`queue.messages.request_timeouts_count_per_second` `DGAUGE`, errors/s	Number of errors when executing the `ReceiveMessage` requests.
`queue.messages.reside_duration_milliseconds` `DGAUGE`, milliseconds	Message processing time in the queue.
`queue.messages.sent_bytes_per_second` `DGAUGE`, bytes/s	Total size of messages sent to the queue per second.
`queue.messages.sent_count_per_second` `DGAUGE`, messages/s	Number of messages sent to the queue per second.
`queue.messages.stored_count` `DGAUGE`, number	Number of messages currently enqueued.
