Traffic Frequency
Planning and Implementing the Control Manager Deployment
The following sources frequently generate traffic on a Control Manager network:
• Logs generated by managed products
• MCP polling and commands
• Trend Micro Management Infrastructure policies
Logs
Managed products send logs to Control Manager at different intervals, depending on
their individual log settings.
Managed Product Agent Heartbeat
By default, managed product agents send heartbeat messages every 60 minutes.
Administrators can adjust this value from 5 to 480 minutes (8 hours). When choosing a
heartbeat setting, choose a balance between the need to display the latest Communicator
status information and the need to manage system resources.
The default setting will be satisfactory for most situations, however should you feel the
need to customize these settings, consider the following:
• Long-Interval Heartbeats (above 60 minutes): The longer the interval between
heartbeats, the greater the number of events that may occur before the Control
Manager console displays the interval.
For example, if a connection problem with an agent is resolved between heartbeats,
it then becomes possible to communicate with an agent even if its status appears as
Inactive or Abnormal.
• Short-Interval Heartbeats (below 60 minutes): Short intervals between
heartbeats present a more up-to-date picture of your network status at the Control
Manager server. However, short-interval heartbeats increase the amount of
network bandwidth used.
