Native Unified Agent metricsNative Unified Agent metrics

Metric name Type, unit	Description
ua.backlog DGAUGE, number	Number of incoming messages for which no outgoing messages have been sent yet. Includes messages from the storage and all incoming but unsent messages. You can safely delete Unified Agent along with directories on the disk, if this metric equals zero and is not incrementing.
ua.bytes_lost RATE, bytes	Amount of data lost in transit.
ua.errors RATE, number	Number of Unified Agent events with ERROR level. For example, data loss due to a corrupted file on disk or exceeded limits, plugin errors while creating a session, or unavailable external services.
ua.messages_lost RATE, number	Number of messages lost in transit.
ua.metrics_lost RATE, number	Number of metrics lost in transit.
