The maximum number of Agents than can be allowed to export, print or mail from Agents Summary Report or Agents Legacy Summary Report.
When trying to export the total number of agents that a DLP system has in DLP (versions 12.5 – 14.0.1) to a file from the Agent Summary Report in the Enforce console the default limit is set 30000.
On the Enforce server (Windows) go to the X:SymantecDLPProtectconfigmanager.properties file or (Linux) /opt/SymantecDLP/Protect/config/manager.properties and edit the following value:
# The maximum number of Agents than can be allowed to export, print or mail from Agents Summary Report or Agents Legacy Summary Report.
com.vontu.manager.advanced.summary.export_or_print_or_mail.maxrows = 30000
Before attempting to change this value make sure to either make a copy of the default setting or the manager.properties file in case you need to rollback for any reason.
Change the 30000 value to a value that will reflect accurately the total number of agents that exist within the DLP system. Example – 40000.
After making the change save the file and restart the DLP services as per – https://support.symantec.com/en_US/article.TECH220062.html
You will now be able to export a report of 40000 agents successfully.
