By default, in the event of a Collector instance crashing, no core dump is generated. This is for security reasons because the Collector may be monitoring encrypted (SSL) traffic. However, some customer issues can only be resolved by Customer Support if a core dump is made available. To enable creation of core dumps, do the following:
As a RUEI_DATA
user, login to the system on which the Collector instance is running and run the following command:
ulimit -c unlimited
Edit the APPSENSOR_HOME
/wg/config/config.cfg
file, and modify the value of CoreSize
setting to -1.
Restart the Collector by running the following command:
appsensor restart wg
When core dumps are enabled, stack trace extracts are stored in the APPSENSOR_HOME
/core_dir
directory. RUEI automatically cleans up any core dumps in the APPSENSOR_HOME
directory, every night at 2:30 AM. In addition, if core dumps are regularly generated, the file system may fill up. Therefore, it is recommended that the default configuration is restored as soon as the required core dumps are generated.
When you contact Customer Support, it is recommended that a Helpdesk report file is created and uploaded to the Service Request (SR). The report file contains extended system information that is useful to Customer Support when handling the reported issues. To generate the report file, select System>Maintenance> Helpdesk report.
In the Reporter user interface, the Helpdesk report can be created manually by doing the following:
Log in to the Reporter system as the RUEI_USER
user.
Run the following commands:
source /etc/ruei.conf project -save --all
Retrieve the generated .tgz
file from the location as indicated by the command output.
Upload the file to the appropriate SR.
