Increasing the Java heap size
After you configure the Cisco UCS agent, if you are monitoring a large Cisco UCS environment, then you might need to increase the heap size for the Java™ data provider.
About this task
The default heap size for the Java™ data provider is 256
megabytes. In large Cisco UCS environments, if the following problems arise, then you might need to
increase the heap size:
- The Java data provider stops because of a javacore problem, and creates a file that is named javacore.date.time.number.txt in the CANDLEHOME\tmaitm6_x64 directory.
- The javacore.date.time.number.txt file contains the string java/lang/OutOfMemoryError.
Procedure
Complete the following steps to set a value of 1 GB as heap size: - Open the %CANDLE_HOME%\TMAITM6_x64\kv6_data_provider.bat file.
- Add the following line before the line that starts with
KV6_JVM_ARGS="$KV6_CUSTOM_JVM_ARGS...:
SET KV6_CUSTOM_JVM_ARGS=-Xmx1024m - Restart the agent.
Complete the following steps to set a value of 1 GB as heap size: - Open the $CANDLEHOME/lx8266/vm/bin/kv6_data_provider.sh file.
- Add the following line before the line that starts with
KV6_JVM_ARGS="$KV6_CUSTOM_JVM_ARGS...:
KV6_CUSTOM_JVM_ARGS=-Xmx1024m - Restart the agent.
