Logging Transactions

The vxtranslog command allows you to log VxVM transactions to a file. The following table demonstrates the usage of vxtranslog:

Transactions are logged to the file, translog, in the directory /etc/vx/log. This path name is a symbolic link to a directory whose location depends on the operating system. If required, you can redefine the directory which is linked. If you want to preserve the settings of the vxtranslog utility, you must also copy the settings file, .translog, to the new directory.

The size of the transaction log is checked after an entry has been written so the actual size may be slightly larger than that specified. When the log reaches a maximum size, the current transaction log file, translog, is renamed as the next available historic log file, translog.number, where number is an integer from 1 up to the maximum number of historic log files that is currently defined, and a new current log file is created.

A limited number of historic log files is preserved to avoid filling up the file system. If the maximum number of historic log files has been reached, the oldest historic log file is removed, and the current log file is renamed as that file.

Each log file contains a header that records the host name, host ID, and the date and time that the log was created.

The following are sample entries from a transaction log file:

The first line of each log entry is the time stamp of the transaction. The Clid field corresponds to the client ID for the connection that the command opened to vxconfigd. The PID field shows the process ID of the utility that is requesting the operation. The Status and Abort Reason fields contain error codes if the transaction does not complete normally. The remainder of the record shows the data that was used in processing the transaction.
