See also SAP Note 1306843 for a reference on information to be provided when you open a support case.


Information to be provided for Support Messages

The following items are required for support messages:

  • Version of software component LM-SERVICE on Solution Manager Java stack
  • Version of component ST on Solution Manager ABAP stack
  • http Remote connection (if not conflicting with company policy) to
    • Solution Manager Java stack
    • Solution Manager ABAP stack
    • Introscope Webview
  • credentials (in Secure Area) for a user with admin permission
  • Log files from component with problems (EM, agent, ...)
  • Screenshots of the problem (if this makes sense)


The mapping between Introscope versions and SAP versions of the Introscope delivery is as follows:

  • Introscope follows a versioning scheme consisting of four parts: major.minor.servicepack.patchlevel, e.g.
  • SAP has a versioning scheme consisting of three parts: version SP supportpackage Patch patchlevel.
  • The mapping is defined as follows for recent versions:
    • Introscope major plus minor is mapped to SAP version
    • Introscope servicepack is mapped to SAP supportpackage
    • Introscope patchlevel is not mapped to SAP patchlevel but counted up stating from 0. Exact mapping you find in Introscope Release Notes.
  • Examples
    • maps to 10.5 SP2 Patch 0
    • maps to 10.5 SP2 Patch 1
  • Exceptions
    • old Introscope maps to 8 SP24 Patch 0 respectively maps to 8 SP25 Patch 0

Enterprise Manager (EM)

Additional Information to be provided for EM Problems

  1. Description of the problem
    • What kind of problem (slow Workstation / Webview, gaps in line chart, MoM losing connection to collectors, ...)?
    • Screenshot of the problem (e.g. from Workstation / Webview screens)
    • Reoccurrence: periodically, occasionally,
    • Reproducible? If yes, how to reproduce?
  2. Time range
    • When did the problem start occurring? 
    • Did the problem disappear without any action? If yes, when did it disappear?
  3. Thread dumps
    • if you observe any kind of hang / crash situation trigger a series of thread dumps for the MoM at least, if possible also for the collectors. See below for details on triggering thread dumps.
  4. Log files
    • Provide a complete set of log files (full contents of /logs folder) for MoM and all collectors. The log files must cover the time range when the problem occurred. Thread dumps will also arrive in the logs folder (em.log / EMService.log)
  5. Heap dumps
    • In case of out of memory situations heap dumps may have been generated (java_*.hprof)  in the EM installation folder. They might be needed as well
  6. Contents of the /data folder of the MoM installation
    • This contains important self-monitoring metrics for post-mortem analysis

EM Additional Diagnostics Options

To enhance the diagnostics options the following configuration changes are recommended (at least in case problems occur)

  • Run the Enterprise Manager on SAP JVM instead of the bundled Oracle / IBM JVM. This will provide more details in thread dumps, address some heap dump problems of Oracle JVM and enable a bunch of other diagnostics facilities. Make sure to use the same major Java version as present in the bundled JVM:
    • Java 8 for EM 10.1 and higher
  • Oracle / SAP JVM: Set the JVM parameter -XX:+HeapDumpOnOutOfMemoryError 

Enterprise Manager Log Files

Most relevant log files for problems with EM in sub directory logs are:

  • IntroscopeEnterpriseManager.log
  • IntroscopeEnterpriseManagerSupport.log

To isolate most SAP-specific log traffic into separate files add the following section of properties to config/

SAP-specific log configuration
# begin log configuration for DpcPush SAP extension
log4j.logger.Manager.SapPush=INFO, sapdpcpush
log4j.appender.sapdpcpush.layout.ConversionPattern=%d{M/dd/yy hh:mm:ss a z} [%-3p] [%c] %m%n
# end log configuration for DpcPush SAP extension

# begin log configuration for SAP Query extension
log4j.logger.Manager.SapQuery=INFO, sapquerylog
log4j.appender.sapquerylog.layout.ConversionPattern=%d{M/dd/yy hh:mm:ss a z} [%-3p] %m%n
# end log configuration for SAP Query extension

As result you will get two additional log files:

  • SapDpcPush.log - contains all activities for pushing metrics to Solution Manager and FRUN for System Monitoring
  • SapQuery.log - contains all activities of Solution Manager retrieving data from Introscope (Extractor Framework, status check, e.g. in "Define CA Introscope")

To get log output with log level DEBUG in file IntroscopeEnterpriseManager.log replace line

log4j.logger.Manager=INFO, logfile


log4j.logger.Manager=DEBUG, logfile

in file file <EM_Home>/config/

On Unix platforms the file em.log in the EM home directory contains helpful information. All console output of the Java VM, including full thread dumps, goes here.

On Windows platforms the logs folder contains an additional file EMService.log. This is written by the Windows service wrapper and may contain important information in case the EM fails to start as Windows service.

Enterprise Manager Version

There are multiple ways to determine the EM version:

  1. The log file IntroscopeEnterpriseManager.log contains the full version string at each startup of the EM. Example:

    8/23/12 09:49:47.289 AM MESZ [INFO] [WrapperSimpleAppMain] [Manager] Introscope Enterprise Manager Release (Build 993800)
  2. Solution Manager discovers the version and displays it in Basic Configuration.

Adapt Enterprise Manager Java VM parameters

Depending on the OS there are different locations where you adapt the Java VM parameters.

Windows Service:
Adapt the file <EM_HOME>/bin/EMService.conf. The properties<number> contain the Java parameters. Java heap size is specified in parameters and

Adapt the file Introscope_Enterprise_Manager.lax in the EM home directory. Property contains all JVM parameters. For Java heap size see Java parameter -Xmx and -Xms.

Recommended Java VM parameters for Enterprise Manager

In case the EM crashes with OutOfMemory (OOM) it makes sense to analyse the Garbage Collections (GC) in more detail. So setting additional java parameters
-verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails is recommended.
With java parameter -Xloggc:gc.log the GC output is redirected from file em.log to a dedicated file gc.log.

The parameter -XX:+HeapDumpOnOutOfMemoryError is usuful to trigger automatically a heap dump in case of OOM.
NOTE: heap dumps get a big as the Java heap size is configured. So make sure you have enough disk space available.

The bigger the Java heap size is configured the more it makes sense to work with parallel GCs by
setting additional java parameters -XX:+UseParNewGC -XX:+UseConcMarkSweepGC  or    -XX:+UseG1GC.

Start/Stop the Enterprise Manager

  1. Windows Service: Default Windows Service display name is "Introscope Enterprise Manager"
  2. Unix: use the script in folder bin:
    • start
    • stop

Register/Unregister Windows Service

The Windows Service to start/stop the Enterprise Manager usually gets registered by default during EM installation. In case you want to register or unregister this Windows Service manually you can do that with the script <EM_HOME>/bin/EMCtrl32.bat respectively EMCtrl64.bat. The command to register the service is EMCtrl64.bat register and EMCtrl64.bat unregister to remove the Windows Service.

The Windows Service display name and other details can be set in file  <EM_HOME>\bin\EMService.conf. Changes to e.g. property wrapper.displayname modifying the default service display name "Introscope Enterprise Manager" of an altready registered Windows Serive only take effect after unregistering and registering the Windows Service.

Other properties you may need to change e.g. if you run several EMs on the same Windows host are and wrapper.description. 

Collect Thread Dumps from the Enterprise Manager

If the Enterprise Manager appears stuck it may make sense to trigger a thread dump. The procedure differs depending on the operating system and the mode it is started.

If the EM is running as service (which is normal): Open a command prompt as adminsitrator and issue the command sc control IScopeEM 255 (IScopeEM is the default name of the service). The thread dump will be appended to the service log file logs/EMService.log. For processing in any thread dump analysis tools you will have to remove the wrapper prefix added to every line.

Example output of the command:

C:\usr\sap\ccms\apmintroscope>sc control IScopeEM 255
         TYPE               : 10  WIN32_OWN_PROCESS
         STATE              : 4  RUNNING
                                 (STOPPABLE, NOT_PAUSABLE, ACCEPTS_SHUTDOWN)
         WIN32_EXIT_CODE    : 0  (0x0)
         SERVICE_EXIT_CODE  : 0  (0x0)
         CHECKPOINT         : 0x0
         WAIT_HINT          : 0x0

Using jmxremote or SAP JVM is an alternative, but requires extra configuration.

If the EM is launched interactively (Introscope_Enterprise_Manager.exe) you can hit Ctrl-Break to trigger a dump. Unfortunately you get it on the console, difficult to capture.

On OS level identify the process ID of the Enterprise Manager, e.g. via the command ps -ef|grep java.
Send signal 3 to this process: kill -3 pid.
The thread dump will be written to the file em.log in the EM installation directory

Collect Heap Dumps from the Enterprise Manager

If the EM crashes and you find errors like "JAVA heap space out of memory" in the IntroscopeEnterpriseManager.log may have either configured the EM with low Java heap size (then see "Adapt Enterprise Manager Java VM parameters" above to increase the heap size) or there could be a memory leak. For the latter heap dumps are needed for analysis. To get heap dumps in case of an OutOfMemory set the additional java parameter -XX:+HeapDumpOnOutOfMemoryError (see "Adapt Enterprise Manager Java VM parameters" above; a restart of the EM is needed). Setting this parameter automatically a heap dump is triggered if an OutOfMemory occurs. The heap dump could consist of more than one file and is usually named java_pid<pid>.*.

In case you want to trigger heap dumps manually set java parameter -XX:+HeapDumpOnCtrlBreak. With every triggered thread dump (see "Collect Thread Dumps from the Enterprise Manager") you then also get a heap dump.
NOTE: heap dumps get a big as the Java heap size is configured. So make sure you have enough disk space available.

Performance / Scalability / Capacity

The EM provides several self-monitoring metrics about its internal status. The metric Overall Capacity (%) is also reported for each EM in the Solution Manager Administration work center. A value of 100% means that it has reached its capacity limit. Short peaks beyond 100% are not critical. Only if the capacity is permanently substantially beyond 100% you will experience problems like missing data points, poor performance, etc. You can find this Overall Capacity (%) metric in the Introscope Investigator via this path: Superdomain -> Custom Metric Host -> Custom Metric Process -> Custom Metric Agent -> Enterprise Manager -> Overall Capacity (%).

A more detailed view is available in the Introscope Investigator tree via the following path: Superdomain -> Custom Metric Host -> Custom Metric Process -> Custom Metric Agent -> Enterprise Manager. If you select the node Enterprise Manager in the tree, the tab Overview on the right side displays eight charts on EM sanity, as shown in the screenshot. It reveals heap utilization, number of metrics and agents.

Perflog Analysis

The EM collects Metrics about itself and reports them to a file called perflog.txt under 15 second time periods. By analyzing the entries in this file, it is possible identify beforehand if the EM is becoming overloaded and avoid future issues. 
To check the EM health check the  Introscope Troubleshooting WIKI page.

Known IntroscopeEnterpriseManager.log entries

DB is not available. Next attempt to retry to connect in 15 seconds.

The IntroscopeEnterpriseManager.log is flooded with entries 

[Manager.AppMap] DB is not available. Next attempt to retry to connect in 15 seconds.

This might happen if you have installed a new EM version 10.7 and have copied all configuration files from an old installation (e.g.). As mentioned in IntroscopeEMUpgrade it is not recommended to copy all configuration files but to transfer any customization of existing configuration files manually.

Follow Knowledge Base Article 1824881 to classify if the missing data should be provided via Introscope.

If you come to the insight that missing metrics indeed should come from Introscope then check KBA 2921337 for troubleshooting.

Java Bytecode Agent (BCA)

Introscope agents of a certain version can connect to Introscope Enterprise Managers of the same or higher version. It is not possible to connect them to an EM with a lower version than the agent is. For more information, refer to the Introscope JAVA Agent WIKI.

Log Files

Relevant log files for problems with the BCA are:

  • from directory /usr/sap/<AgentSID>/<AgentNo>/SMDAgent/applications.config/<Release>/wily
    • IntroscopeAgent.profile
  • from directory /usr/sap/<AgentSID>/<AgentNr>/SMDAgent/temp
    • IntroscopeAgent.<SID_Instance>_server*.log
    • AutoProbe.<SID_Instance>_server*.log
  • from directory /usr/sap/SID>/<inst>/work of the managed system if it's a Netweaver java node:
    • dev_server0 (contains the actually used JVM parameters)
    • std_server*.out

 If requested by SAP Development set in IntroscopeAgent.profile the property  log4j.logger.IntroscopeAgent from

log4j.logger.IntroscopeAgent=INFO, logfile


log4j.logger.IntroscopeAgent=DEBUG, logfile

A restart is not required. Do not forget to reset the value back to INFO after investigating the issue.

Agent Version

The agent version can be determined via one of the following procedures:

  • Check the log file IntroscopeAgent*.log for the right agent. The agent version is dumped at every restart of the Java VM.
  • Check the Introscope Investigator tree. For each agent, the node Agent Stats contains
    • Agent build and release
    • SAP build timestamp
    • location of the agent profile that is used

Missing CPU Metrics

The CPU node in the Investigator tree of the byte code instrumentation agent (e.g. Netweaver agent) is populated via a native library, the so-called platform monitor. There are multiple possible reasons why this node might be missing:

  • there is no platform monitor extension for all supported Netweaver platforms. As fallback you can use the OS metrics as provided by the Introscope host adapter (under node SAP Host Agent)
  • on Windows: If the user running the  Java VM is not in the administrators group it must be added to the group Performance Monitor Users to obtain the privileges required to read performance data.

Missing JMX Metrics

For troubleshooting JMX metric collection in the agent you can increase logging of the JMX service by setting these two additional properties:

JMX debug logging
log4j.logger.IntroscopeAgent.JMX\ Service=ALL, logfile
log4j.logger.IntroscopeAgent.JMXService=ALL, logfile

In general polling of particular MBeans will be switched off until the next restart of the Java VM as soon as any exception occurs for polling that MBean.

For Netweaver there is a known problem that reporting of http sessions ("Current Http Sessions") stops reporting. See SAP Note 2067705 for a fix.

Troubleshoot Netweaver Jmx Metrics

Java Managed System does not start due to missing Agent.jar

If a Java Managed System has been instrumented for CA Introscope via the Java VM parameter -javaagent:/some/path/to/Agent.jar and the file Agent.jar is not accessible by the instrumented Java VM then it fails to start. Possible reasons why the file Agent.jar is not accessible:

  1. The corresponding Diagnostics Agent has been deleted before the CA Introscope instrumentation has been removed from the Java Managed System. The Java Managed System does not start anymore because the required Agent.jar in the Diagnostics Agent file system has been deleted.
  2. The managed Java VM does not have read access to the file system tree where the Introscope agent is located (e.g. user SAPService<SID> on Windows starting the SAP Netweaver system)

In the first case the instructions for uninstalling the Introscope Byte Code Agent were not followed correctly.
You can find those instructions in the Introscope Installation or Setup Guide for your Solution Manager Release.

These installation or setup guides can be found at
=> Alphabetical Index => S
=> SAP Solution Manager
=> "your solution manager release"
=> "one of the sections on installations"
=> "respective Wily Introscope guide".

In these guides, please refer to the section titled "Uninstalling Introscope Agents". It is recommended to use the SAP Solution Manager provided mechanism to remove the problematic properties.
In case the Diagnostics Agent was already deleted, it may be necessary to delete the properties by hand. In case of problems please create a ticket at component SV-SMG-DIA-WLY-BCA.

Log Files and Log Levels

Relevant logfiles for problems with Introscope Host Adapter are:

  • SMDAgentApplication*.log (most content here)
  • SMDSystem*.log (in case wilyhost does not start up at all)
    They are persisted in directory /usr/sap/<SMDAgentID>/<InstanceNo>/SMDAgent/log

The log level for SMDAgentApplication.log might have to be increased to DEBUG for troubleshooting. This is done via diagnostics agent administration.

If the Introscope host adapter does not show up in the Investigator the file jvm_SMDAgent.out may also be relevant. It corresponds to IntroscopeAgent*.log of the BCA. To increase the log level for the Introscope runtime of the host adapter (in jvm_SMDAgent.out) edit the application resource "IntroscopeSapAgent.profile" and change the property

log4j.logger.IntroscopeAgent=DEBUG, console

Thread Dumps

Thread dumps for the Introscope host adapter means thread dumps for the whole diagnostics agent. They can be triggered in various ways, e.g.:

  1. Via the SAP Management Console / MMC: Right-Click on the java procees for the agent and click Dump Stack Trace
  2. On OS level (Unix): find out the process ID of the agent process and issue the command kill -3 <pid>

In any case the thread dump is written to the file std_smdagent.out in the work directory of the diagnostics agent.

  1. Former Member

    I had issues getting the workstation to start for Wily

    When using Java 1.7 u71 or Java 1.8 u25 on the client desktop, the Webstart Workstation fails to start

    Follow these directions, it now works for Java 7 (1.7):

    To workaround the problem:

    1. Make a backup copy of the file EM_HOME/product/enterprisemanager/plugins/com.wily.introscope.workstation.webstart_9.x.0/WebContent/jnlp/workstation.jsp


    2. Edit the workstation.jsp file and locate the comment "<! -- Information usually specified in the config.ini -->"


    3. Immediately below that line, add the following line and save the file:

    <property name="" value="osgi"/>


    4. Clear the browser and Java caches on the client desktop.


    5. Relaunch the Webstart Workstation and the problem should be resolved.

  2. Former Member

    I had issues in getting the wily workstation started, but it did not just work after apply the work around mentioned in Workstation webstart section about. We had to change the j2se version to our client java version which 1.8*

    Workstation webstart

    The Java WebStart for the Introscope Workstation fails for higher patch levels of Java 7 and for Java 8 due to changes in the security checks of Java WebStart. In some cases the launch of the Workstation fails silently, in other cases an exception is shown.

    In addition, for the following Java patch levels work-arounds are available:

    • Java 7 Update 71 (Java 1.7.0_71) and newer: Workstation WebStart client fails again. Workaround for Introscope 9.5.6: add line <property name="" value="osgi"/> to file  <EM_HOME>/product/enterprisemanager/plugins/com.wily.introscope.workstation.webstart_<version>/WebContent/jnlp/workstation.jsp. 
    • Modify the j2se version in same file <j2se version=1.x*" here x is your java version eg. java8, then its 8
    1. Hi Raghu,

      thanks for your contribution. As a general note I have updated the page to point out that all problems are resolved for Introscope 9.7 and higher versions.
