The memory utilization for a particular service on the
container application depends on the complexity of service implementation, payload, workload, the number of services deployed on the
container application
, CPU or memory resources made available to the
container
.
Prerequisites
Assuming all the components of the engine are tuned for debugging high memory utilization issues on the
container application
, collect the following data that helps in further debugging and understanding the issues.
Procedure
-
Capture heap dump on the
container application when memory issues are observed on the
container application
.
The heap dump can be analyzed using memory analyzer tool for checking memory leaks and top components of memory.
-
Capture
jstat data for checking the allocation and utilization of different memory pools for 5 minutes run.
jstat –gc <PID of container application> > jstat_gc.txt
-
Capture thread dumps for analyzing the thread state and calls. Capture 5 thread dumps at an interval of 5 seconds each. Redirect all the collected threads dumps to separate files.
-
Capture top CPU consuming threads by using
jvmtop utility for 5 minute run.
For more information about
jvmtop utility, see support article
KB000034702.
./jvmtop <PID of container application> > JVM_topthreads.txt
-
Capture method level CPU profiling data using
jvmtop for 5 minutes run.
./jvmtop --profile <PID of > > JVM_CPUProfile.txt
-
Capture
container
logs for the test run duration.
-
Capture the CPU and memory utilization data of the
container application for 5 minutes run.
-
Check the BW_JAVA_OPTS and other run-time parameters with which the container is running. This helps analyze the JVM parameters and other engine tuning parameters.
-
Capture system configurations of servers such as CPU details, RAM, and number of cores where
TIBCO BusinessWorks™ Container Edition
applications, external services, and load generator are running. Capture details of
/proc/meminfo and
/proc/cpuinfo files.
cat /proc/meminfo and cat /proc/cpuinfo
