IS Metering - metering.agent.properties update for parameter metering.report.period not working

Product/components used and version/fix level:

10.15 Metering

Detailed explanation of the problem:

Hi All,

We have IS Metering in an IS 10.15. We have updated the metering.report.period parameter to 2400 in metering.agent.properties but still it is running after 1 hour only as per previous config of 3600 and not every 40 minutes as per new update

For the Property Update to reflect is IS Restart or any other Action needs to be performed?

PathD:\InstallationDirectory\common\metering\conf

File Namemetering.agent.properties

Error messages / full error message screenshot / log file:

Question related to a free trial, or to a production (customer) instance?
