RDM Server Statistics
The RDM Server Statistics form displays all statistics gathered
from a call to gather statistics from the CV11 Server. You can
refresh the statistics by selecting the REFRESH button. When
the statistics are refreshed, all accumulated statistics are totaled.
This diagnostic tool enables system technicians to benchmark
CV11 Server and Extension Module performance. This is meant
to help troubleshoot server related issues.
These statistics are primarily to enable the Collect!
Technical Services Team to more quickly pinpoint issues
related to the CV11 Server and Extension Module.
The RDM Server Statistics form may be accessed through
the System, Diagnostics menu. Select Db Statistics to open
the form.
A complete list of the defined server constants appears below.
These constants contain the index into the array of longs
returned from s_statistics. All values are totals and do not show
current values. For example, the value returned in the LOGINS
field represents the total number of user logins that have
occurred since the server was started, not the current number
of active users. To obtain the current number, subtract the
total of LOGOUTS from LOGINS.
Page Zero Read
Total number of times RDM Server performed
a page zero read from a database file.
Page Zero Write
Total number of times RDM Server performed a
page zero write to a database file.
Open Db Tables
Total number of times a database open required a
database dictionary read from disk.
Close Db Tables
Total number of times a database dictionary was removed
from memory. This counter is incremented when all users
of the database have called d_close and the table can be
removed from RDM Server memory.
Open Db
Total number of times RDM Server performed a database open.
Close Db
Total number of times RDM Server performed a database close.
Group Lock Request
Total number of lock requests RDM Server serviced. This
counter is incremented when RDM Server receives a lock
request, whether it was granted, blocked, timed out, or
an RDM Server error occurred.
Group Lock Blocked
Total number of lock requests blocked because of an
incompatible lock.
Group Lock Timeout
Total number of times a lock timed out because of an
incompatible lock.
Instance Read Locks
Total number of times an instance read lock is granted.
Table Read Locks
Total number of times a table read lock is granted.
Instance Write Locks
Total number of times an instance write lock is granted.
Table Write Locks
Total number of times a table write lock is granted.
Freed Locks
Total number of successful requests to free instance
and table locks.
Transaction Begins
Total number of times a database transaction began.
This counter is incremented after every successful
d_trbegin call to an open database.
Transaction Ends
Total number of times a database transaction ended.
This counter is incremented after every successful
d_trend call to an open database.
Transaction Aborts
Total number of times a transaction aborted.
This counter is incremented after a transaction
was aborted by a d_trabort call on an open database.
Change Log Write
Total number of times the change log is updated.
This counter is incremented when a transaction is
written to a change log on disk.
Change Logs
Total number of change logs created. This counter is
incremented when RDM Server creates multiple change
log cycles.
Change Logs Bytes Write
Total number of bytes written to change logs. This counter
is increased by the size of each write and is only
incremented each time CHANGE LOG WRITE
is increased.
Open Change Log
Total number of times the change log is opened. This
counter is incremented each time RDM Server opens
the change log file.
Close Change Log
Total number of times the change log file is closed. This
counter is incremented each time RDM Server closes the
change log file.
Transaction Rollbacks
Total number of transaction rollbacks. This counter is
incremented after a call to d_trrollback is successful
on an open database.
Checkpoints
Total number of cache checkpoints. See Chapter 3
of the RDM Server User's Guide for information on
checkpoint processing.
Piggybacks
Total number of times a contiguous block writes to a
database file during a checkpoint. This is a measure
of the fragmentation of the checkpoint writes. Higher
values mean less fragmentation.
Server Rpc Total
Total number of client RPC calls serviced by the server.
Logins
Total number of times the server processed a login.
Logouts
Total number of times the server processed a logout. This
counter is increased when a successful client logout is
serviced by RDM Server.
Client Aborts
Total number of times RDM Server aborted a client session.
For every session abort, a logout will be automatically
performed by RDM Server, hence the LOGOUTS total is
also incremented.
Requests
Total number of d_ function calls. This counter is increased
each time a d_ function call is made to RDM Server by a
client or by an RDM Server extension module.
Db Function Calls
Total number of d_ function calls. This counter is increased
each time a d_ function call is made to RDM Server by a
client or by an RDM Server extension module.
Db Errors
Total number of database errors. This counter is increased
each time a database error occurs.
Normal Requests
Total number of normal RPC requests. This counter is
increased each time RDM Server receives a normal RPC
request that is serviced by a normal RDM Server thread.
Pri Requests
Total number of priority RPC requests. This counter is
increased each time RDM Server receives a priority RPC
request that is serviced by a priority RDM Server thread.
