How to reformat MQ error message

The content of the MQ error log is as following:

12/08/2018 08:21:42 AM - Process(16535.4) User(root) Program(amqzmur0)
                    Host(love) Installation(Installation1)
                    VRMF(8.0.0.9) QMgr(QM2)
                 
AMQ6287: WebSphere MQ V8.0.0.9 (p800-009-180321.1).

EXPLANATION:
WebSphere MQ system information:
Host Info         :- Linux 2.6.32-696.13.2.el6.x86_64 (MQ Linux (x86-64
platform) 64-bit)
Installation      :- /opt/mqm (Installation1)
Version           :- 8.0.0.9 (p800-009-180321.1)
ACTION:
None.
-------------------------------------------------------------------------------
12/08/2018 08:21:41 AM - Process(30069.1) User(root) Program(runmqchl)
                    Host(love) Installation(Installation1)
                    VRMF(8.0.0.9) QMgr(QM2)
                 
AMQ9213: A communications error for TCP/IP occurred.

EXPLANATION:
An unexpected error occurred in communications.
ACTION:
The return code from the TCP/IP (connect) call was 113 (X'71'). Record these
values and tell the systems administrator.
----- amqccita.c : 1278 -------------------------------------------------------
12/08/2018 08:21:41 AM - Process(30069.1) User(root) Program(runmqchl)
                    Host(love) Installation(Installation1)
                    VRMF(8.0.0.9) QMgr(QM2)
                 
AMQ9999: Channel 'QM2.V9QM2' to host '192.168.136.123(1415)' ended abnormally.

EXPLANATION:
The channel program running under process ID 30069 for channel 'QM2.V9QM2'
ended abnormally. The host name is '192.168.136.123(1415)'; in some cases the
host name cannot be determined and so is shown as '????'.
ACTION:
Look at previous error messages for the channel program in the error logs to
determine the cause of the failure. Note that this message can be excluded
AMQERR01.LOG


However I would like to reformat the error log as following:

12/08/2018 08:21:42 AM AMQ6287: WebSphere MQ V8.0.0.9 (p800-009-180321.1).
12/08/2018 08:21:41 AM AMQ9213: A communications error for TCP/IP occurred.
12/08/2018 08:21:41 AM AMQ9999: Channel 'QM2.V9QM2' to host '192.168.136.123(1415)' ended abnormally.

Only grep is not enough to handle, we must ask help from 'sed"

grep -o -E ".*[0-9]{2}:[0-9]{2}:[0-9]{2}\ [A,P]{,1}[M]{,1}[:space:]{,1}|AMQ[0-9]{4}:.*" AMQERR01.LOG|sed '$!N;s/\n/\ /'

grep:

-o: only print the match string
*** AIX 上的opensoure grep 要用[[:space:]]

sed:

N means read the next line (可用來合併二行)
$!N means read the next line unless it is the last line (最後一行不做)

sed   N和$!N 的理解使用

How to change the MQ qmgr error log file permission to allow user not in mqm group could access it

If you would like to allow user in non mqm user group to access the qmgr error log, you may try to modify the file and directory permission for the non mqm user group. However you will find after qmgr updating the content of the qmgr error log or qmgr restart, the qmgr sets all the files and folder permission back to the default setting. The non mqm user can’t access the error log again. To solve this issue, you need to use the following parameter in the qm.ini file.

Filesystem:ValidateAuth=No

This setting will cause the queue manager to leave the permissions on the error log files unaltered.

IT09572: ValidateAuth=No does not maintain file permissions on queue manager error logs
