fteSetAgentTraceLevel (set WebSphere MQ Managed File Transfer agent trace level)
Use the fteSetAgentTraceLevel command to modify the current trace level for an agent dynamically.
Purpose
Use this command to switch agent trace on and off or to change the level of agent trace that is set. When you use the fteSetAgentTraceLevel command, you do not have to shut down and restart an agent to modify the trace level. The trace files produced are located in MQ_DATA_PATH/mqft/logs/coordination_qmgr_name/agents/agent_name/logs/trace%PID%/trace%PID%.txt, where %PID% is the process ID for the agent instance.
In WebSphere® MQ Managed File Transfer Version 7.5, the fteSetAgentTraceLevel command also writes a trace for the agent process controller. The trace files produced are located in MQ_DATA_PATH/mqft/logs/coordination_qmgr_name/agents/agent_name/logs/pctrace%PID%/pctrace%PID%.txt, where %PID% is the process ID for the agent instance.
You can also use the command to cause the agent process to generate a Javacore. The agent generates a Javacore file in the following directory: MQ_DATA_PATH/mqft/logs/coordination_qmgr_name/agents/agent_name.
Because running trace can affect your performance significantly and can produce a large amount of trace data, run trace with care and only when necessary. Typically, enable trace only when asked to do so by your IBM® service representative.
You can set further trace properties, for example trace file size and the number of trace files to keep, in the agent.properties file. These properties are described in Advanced agent properties.
Specify the optional -p parameter for this command only if you want to use a set of configuration options different from your default set. See The agent.properties file for more information.
Syntax
Parameters
- -traceAgentclasses=level
- Required. Level to set the agent trace and which classes to apply
the trace to. Specify the following format:
For example:classes=level
com.ibm.wmqfte=all
Specify a comma-separated list of class specifications that you want the level of trace to apply to. If you do not specify this parameter, the trace level is applied to all agent classes.
You can substitute classes with an MQMFT package name to trace a specific package only. However, because this option captures just a subset of the agent's behavior, you are generally not recommended to use package filtering.
If (classes) start with a plus sign (+), the list of trace classes following the plus sign are added to any existing trace classes currently being traced.
The valid trace level options are as follows and are listed in ascending order of trace file size and detail:- off
- Switches the agent trace off but continues to write information to the log files. This is the default option.
- flow
- Captures data for trace points associated with processing flow in the agent.
- moderate
- Captures a moderate amount of diagnostic information in the trace.
- verbose
- Captures a verbose amount of diagnostic information in the trace.
- all
- Sets agent trace to run on all agent classes.To start full tracing for the agent, run the following command:
To stop full tracing for the agent, run the following command:fteSetAgentTraceLevel -traceAgent =all AGENT_NAME
fteSetAgentTraceLevel -traceAgent =off AGENT_NAME
- -disableOnAnyFFDC
- Optional. If this parameter is specified, trace is disabled on
the agent when it generates a First Failure Data Capture (FFDC) file.
You can specify only one of the -disableOnAnyFFDC and -disableOnFFDC parameters.
- -disableOnFFDCFFDC_specification
- Optional. If this parameter is specified, trace is disabled on
the agent when it generates a First Failure Data Capture (FFDC) file
that matches the FFDC_specification. FFDC_specification is
a comma-separated list of values. The format of the values can be
either:
- class_name
- The name of the class where the FFDC originated. For example,
com.ibm.wmqfte.classA
. - class_name:probe_ID
- The name of the class and the probe ID of the location in the
class that the FFDC originated from. For example,
com.ibm.wmqfte.classB:1
.
You can specify only one of the -disableOnAnyFFDC and -disableOnFFDC parameters.
- -jc
- Optional. Requests that the agent generates a Javacore file. The IBM service team may request that you run the command with this parameter to assist with problem diagnosis. This parameter cannot be used with any other parameter.
- -pconfiguration_options
- Optional. This parameter determines the set of configuration options
that is used to set the agent trace level. Use the name of a non-default
coordination queue manager as the input for this parameter. The command
then uses the set of properties files associated with this non-default
coordination queue manager.
If you do not specify this parameter, the set of configuration options based on the default coordination queue manager is used.
- agent_name
- Required. The name of the WebSphere MQ Managed File Transfer agent that you want to set the trace level for.
- -? or -h
- Optional. Displays command syntax.
Example
In this example, the trace level is set toall
for all classes for AGENT1: fteSetAgentTraceLevel -traceAgent com.ibm.wmqfte=all AGENT1
In
this example, the trace level is set to all
for the
classes com.ibm.wmqfte.agent.Agent
and com.ibm.wmqfte.cmdhandler
for
AGENT1:
fteSetAgentTraceLevel -traceAgent com.ibm.wmqfte.agent.Agent,com.ibm.wmqfte.cmdhandler=moderate
AGENT1
fteSetAgentTraceLevel -traceAgent com.ibm.outer=verbose AGENT1
fteSetAgentTraceLevel -traceAgent +com.ibm.outer.inner=off AGENT1
