Chapter 4, Logging Commands and Transactions

Associating Command and Transaction Logs

The Client and process IDs that are recorded for every request and command assist you in

correlating entries in the command and transaction logs. To find out which command

issued a particular request in transaction log, use a command such as the following to

search for the process ID and the client ID in the command log:

# egrep -n PID cmdlog | egrep Clid

In this example, the following request was recorded in the transaction log:

Wed Feb 12 21:19:36 2003

Clid = 8309, PID = 2778, Part = 0, Status = 0, Abort Reason = 0

DG_IMPORT foodg

DISCONNECT <no request data>

To locate the utility that issued this request, the command would be:

# egrep -n 2778 cmdlog | egrep 8309

7310:# 8309, 2778, Wed Feb 12 21:19:36 2003

The output from the example shows a match at line 7310 in the command log. Examining

lines 7310 and 7311 in the command log indicates that the vxdg import command was

run on the foodg disk group:

# sed -e ’7310,7311!d’ cmdlog

# 8309, 2778, Wed Feb 12 21:19:36 2003 7311

/usr/sbin/vxdg -m import foodg

Note If there are multiple matches for the combination of the client and process ID, you

can determine the correct match by examining the time stamp.

If a utility opens a conditional connection to vxconfigd, its client ID is shown as

zero in the command log, and as a non-zero value in the transaction log. You can

use the process ID and time stamp to relate the log entries in such cases.
