Both counter name and the values are updated for every heartbeat. This can be improved by sending names and values for the first time and only the values after that. The frequency can be reduced by doing update only when the counters got changed. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
