DX Application Performance Management

If I invoke Command Line Workstation in interactive mode in the following manner:
"cat input.txt | java $MY_OPTIONS -jar CLWorkstation.jar > output.txt

The output file contains the correct result for the first command contained in the input file followed by:
"Unable to connect to the Enterprise Manager XYZ"

input.txt:
list agents matching (.*)Agent1(.*)
list agents matching (.*)Agent2(.*)
----------------------------------------------

output.txt:

Host|Process|Agent1
Unable to connect to the Enterprise Manager XYZ:5001

DEBUG mode logging indicates that CLW is trying to connect a new Workstation instance instead of "re-using" the old connection :

Caused by: com.wily.isengard.messageprimitives.MaxMomsExceededException: MOM connection from Node=Workstation_1223, Address=Blah, Type=socket was rejected since the clamp value of 1 has been reached

Can someone help Richard with next steps? 

Hi Richard,

Interesting. I cannot even get that standard input method to work at all with my 10.7 CLWorkstation.jar. 

I always get a syntax error implying I have not included a "list" option. (adding any CLW trace option like "-Dintroscope.clw.debug=true" shows no more)

===

# echo $MY_OPTIONS
-Duser=admin_local -Dhost=willy03-i2438.ca.com -Dport=5001

# java $MY_OPTIONS -jar CLWorkstation.jar list agents matching \(.*\)Tomcat\(.*\)
willy03-I2438|Tomcat|Tomcat Agent

# cat input.txt
list agents matching \(.*\)Tomcat\(.*\)
list agents matching \(.*\)Tomcat\(.*\)

# cat input.txt | java $MY_OPTIONS -jar CLWorkstation.jar

Usage: java -Xmx128M <EM_logon> <Trace_props> -jar CLWorkstation.jar <Arguments>

Where:....

Hiko_Davis might have some more input.

Hi Richard,

Did you leave off "-i" from your command in your original post?

Sorry my bad I had not used the interactive mode "-i" option before and with that added I now have it working and I am seeing the expected 2 results:

# echo $MY_OPTIONS
-Duser=admin_local -Dhost=willy03-i2438.ca.com -Dport=5001

# cat input.txt
list agents matching .*EPAgent.*
list agents matching .*Tomcat.*

# cat input.txt | java $MY_OPTIONS -jar CLWorkstation.jar -i
willy03-I2438|EPAgentProcess|EPAgent
willy03-I2438|Tomcat|Tomcat Agent

I can only find "Caused by: com.wily.isengard.messageprimitives.MaxMomsExceededException: MOM connection from Node=Workstation...." previously reported for MOM-Collector handshake connection failures.

I am using a standalone EM and not a cluster, but will try to test on that next.

Lynn

Hi Richard,

I tested with a 10.7 mini cluster and I am still not seeing a problem when connecting to the MOM

CLW DEBUG ("-Dintroscope.clw.debug=true") output below shows it is does create a separate socket connection/workstation session for each line of standard input:

I see similar in the EM log with the first Workstation session being logged out before the 2nd one is started:

So CLW starting a separate Workstation session for each line of input is the correct behaviour, but I cannot explain why you are having a problem starting the 2nd Workstation session.

If this important for you please create a support case and refer to this thread so we can investigate further.

Thanks
