Using MEASURE Counters
LightWave Server supports several 'user defined' MEASURE counters which you can use to help analyze performance of your LightWave Server application. The available MEASURE counter names and types are shown below:
| Counter Name | Type | Description |
|---|---|---|
| lw-connect | qbusy | The amount of time spent processing an inbound connection. |
| lw-conn-ssl-hs | qbusy | The amount of time spent processing the SSL/TLS handshake for a connection. |
| lw-request | qbusy | The amount of time spent receiving the request from the client over the network. |
| lw-deserialize | qbusy | The amount of time spent deserializing the request payload into the server request IPM. |
| lw-pathsend-io | qbusy | The amount of time spent sending the request and receiving the reply from a Pathway server. |
| lw-process-io | qbusy | The amount of time spent sending the request and receiving the reply from a process server. |
| lw-serialize | qbusy | The amount of time spent serializing the reply IPM into the response payload. |
| lw-request | qbusy | The amount of time spent sending the response to the client over the network |
| lw-diag-log | qbusy | The amount of time spent generating the diagnostic log. |
| lw-msg-log | qbusy | The amount of time spent filtering and delivering the message logging events. |
| lw-requests | accum | The total number of requests processed |
| lw-ssl-hs | accum | The total number of SSL/TLS handshakes |
| lw-recv-bytes | accum | The total number of bytes received over the network |
| lw-send-bytes | accum | The total number of bytes received over the network |
| lw-sock-recvs | accum | The total number of TCP/IP socket recv operations processed |
| lw-sock-sends | accum | The total number of TCP/IP socket send operations processed |
| lw-sock-connects | accum | The total number of TCP/IP connection requests processed. |
| lw-sock-accepts | accum | The total number of TCP/IP accept operations processed. |
| lw-deleg-fails | accum | The total number of SERVER to SWORKER requests delegations that have failed. This may indicate that the SWORKERs are over capacity. |
| lw-pathsend-ios | accum | The total number of Pathsend I/Os processed. |
| lw-process-ios | accum | The total number of process server I/Os processed. |
| lw-pathsend-max | snapshot | The maximum number of concurrent Pathsend I/O operations |
| lw-process-max | snapshot | The maximum number of concurrent process server I/O operations. |

These MEASURE counters may differ from values recorded in diagnostic logs. The diagnostic log measures elapsed time whereas the MEASURE counters represent actual work time.
