APM Top 20 Accessed KB Articles for October 2014
1. Bash Code Injection aka "Shellshock" and CEM TIM and TIMSoft TEC618037
https://support.ca.com/irj/portal/kbtech?docid=618037
Description:
The CEM Transaction Impact Monitor (TIM) is a passive network probe that collects business transaction information on
HTTP/HTTPS traffic through a network span or tap. The CEM TIM is a C++ based application that runs on specific versions of the
Linux operating system and does not use the Bash shell for any of its operational functions, however prior to version 9.6, the
TIM installation script does use the bash shell.
It has been recently disclosed by industry experts that most versions of Unix, Linux, OSX and other variants are susceptible to
a security issue that allows the execution of bash code injection. This is being referred to in the media as "Shellshock".

3. Explaining and Addressing an Agent Reaching Transaction Trace Component
Limit TEC597757
https://support.ca.com/irj/portal/kbtech?docid=597757
Description:
This article will discuss the causes and how to address "[WARN] [IntroscopeAgent.WilyTransactionStructure]Transaction trace
component limit of 5000 reached, recording of any new components will cease for this transaction."
4. The RTTM Service will not start. Instead, it appears to be stuck and the
Status is "IN PROGRESS". What should I do to get the Service started? TEC596475
https://support.ca.com/irj/portal/kbtech?docid=596475
Description:
The RTTM service in APM can get stuck and display in the APM CEM GUI that the status of the service is "In Progress". This
status persists across restarts of the Enterprise Manager, and the Start and Stop buttons are not available to click.
Using a database tool (such as pgadmin III or SQL*Plus), access the APM Database, and open the table
"ts_monitor_child_service". Look for the item where the column "ts_child_service_id" is "7", and check the value of the column
"ts_started" - it will have a value of "2". If the issue persists, contact CA Technologies APM Technical Support for next
steps. This could include an upgrade to a later release where certain causes of this condition have been eliminated.

9. Approaches to Use for Three common APM CE Situations - Not Seeing Enough Defects, Response Time Too Low/High, Not Seeing All
https://support.ca.com/irj/portal/kbtech?docid=598247
Components TEC598247
Description:
Three common APM CE questions can result in cases that require some investigation. Here is the approach that is used to resolve
these questions:
Why is the transaction defect count too low?
Why is the transaction response time too low/high? (Especially against another third-party monitoring tool)
Why do I not see all the components in a defect?
10. Duplicate or tardy metric value reported TEC595225
https://support.ca.com/irj/portal/kbtech?docid=595225
Description:
The EMService.log contain many messages "Duplicate or tardy metric value reported", for example:-
SuperDomain|*******|WebSphere|**********/**********Cluster_*******Node01
|WebSphereMQ|Connector|mqseries_tst|mqsnttst|Queues|SERVICES.RESPONSE|Get:Concurrent Invocations (time=87239764/last closed
timeslice=87239764); ignoring.
SuperDomain|*******|WebSphere|**********/**********Cluster_*******Node01
|WebSphereMQ|Connector|mqseries_tst|*CA|Operations|Close:Concurrent Invocations (time=87298547/last closed timeslice=87298547);
ignoring
The messages are reported against only those agents enabling the MQ metrics, and all such MQ metrics are aggregated ones
(calculated inside of the MQAgent).

16. Stopping the Autoprobe log from expanding or getting excessively large. TEC617255
http://www.ca.com/us/support/ca-support-online/product-content/knowledgebase-articles/tec617255.aspx
Description:
A JVM's use of dynamically created classes, typically with a $ in the class name, can cause the Autoprobe log to grow
excessively large. The logs are filled up with repeating class names :
Processing class com/package/class$name1
Processing class com/package/class$name2
Processing class com/package/class$name3
Processing class com/package/class$name4
Processing class com/package/class$name5
Processing class com/package/class$name1
Processing class com/package/class$name2
Processing class com/package/class$name3
Processing class com/package/class$name4
Processing class com/package/class$name5
The above is a simplified example. However, typically part of the class or package name could be made up of random characters.
