-ppv mlsrv16 option

mlsrv16 -c "connection-string" -ppv period ...

These values can provide insight into the state of the server, and are useful for determining the health and performance of the MobiLink server. For example, one could look at the DB_CONNECTIONS and LONGEST_DB_WAIT values to look for potential problems with the -w option or in the synchronization scripts. The values also provide an easy way to track system wide throughput measures, such as the number of rows uploaded or downloaded per second and the number of successful synchronizations per second.

The suggested period is 60 seconds.

If the period is set too small, the log will grow very quickly.

Each row of output is prefixed with PERIODIC: to aid in searching for and filtering out the values.

The printed values can include the following information:

PRIMARY_IS_KNOWN	Indicates if the primary server is known or not. Shows 0 if the server does not care what the primary server is. Shows 1 if the server knows what the primary server. Shows 2 if the server does not know what the primary server is.
RAW_TCP_STAGE_LEN	The length of the network work queue.
SERVER_IS_PRIMARY	Indicates if the server is primary or secondary. Shows 1 if the server is primary, otherwise shows 0.

TCP_CONNECTIONS_CLOSED	The total number of connections ever closed.
TCP_CONNECTIONS_OPENED	The total number of connections ever opened.
TCP_CONNECTIONS_REJECTED	The total number of connections ever rejected.
TIMED_WORK_STAGE_LEN	The length of the dynamic caching work queue.
TRACKED_MEMORY	The amount of memory allocated by the server. Use this metric for non-Windows systems where the MEMORY_USED metric is unavailable. On Microsoft Windows systems, use the MEMORY_USED metric for increased accuracy.
VM_MEM_USE	The amount of memory used by any attached VMs.
