DTL Counters
You can use DTL counters in Workflow.
Counter Name | Description | |
---|---|---|
DTL Pending Packets Acknowledged | Shows how many non-specific packet acknowledgements are in the queue. If this number starts increasing, it indicates that DTL is having difficulties processing. | |
DTL Received Packets Queued | Monitors the queue from the RxThread to PacketProcessThread. If you are generating many events with multiple clients, this counter should increment. | |
DTL Received Packets Dropped | DTL limits the size of the queue from the RxThread to the PacketProcessThread to a maximum of 1,000 (ReceiveQueueLimit) packets. If the RxThread gets a packet when the queue is full, the packet is dropped, and this counter increments. | |
DTL Send Packets Queued | Monitors the queue of packets to be sent, which is added to by the BuildPacketThread and emptied by the TxThread. Normally, this queue is not busy. It indicates that something is generating packets faster than they are being transmitted. If your network connection is slow, or is very busy and generating a high volume of events, this counter may increase. | |
DTL Record Rate Changed | Reports the number of change records per second coming into the DTL subsystem (typically from an event subsystem), which is the event producer side of the multi-server system. When events are generated, this rate counter moves. | |
DTL Change Records Queued | Monitors the queue of change records coming from the Events subsystem (and possibly others) that are emptied by the BuildPacketThread. Because the BuildPacketThread pauses to try to get multiple changes per packet, this counter should change when there are a high volume of events. | |
DTL Change Records Dropped | The queue of change records is limited to 1,000. If more change events come in than can fit in the queue, DTL starts dropping change records, and this counter increases. Typically, this counter does not move, but if the events are generated fast enough, it may move. |
