Valid for agent 9.1 and later:
You can limit the number of 9.1 and later agents that are configured as disallowed but can passively connect to a standalone Enterprise Manager or Collector. Passively connected agents have these characteristics:
  • Do not send any metric data to the Enterprise Manager.
  • Do not try to reconnect to other Enterprise Managers that become available.
Setting this clamp limit is performance measure because it limits the number of connections to an Enterprise Manager. Each connection requires some resources, so an overly high number of connections can decrease Enterprise Manager performance.
Follow these steps:
  1. Go to the
    <EM_Home>
    \config directory and open the IntroscopeEnterpriseManager.properties file.
  2. Set the introscope.enterprisemanager.agent.disallowed.connection.limit property.
  3. Save the IntroscopeEnterpriseManager.properties file.
    The setting is applied when the Enterprise Manager checks the property file during a hot deploy, which occurs about once every 60 seconds.
    When the clamp is hit and an agent configured as disallowed tries to connect to the Enterprise Manager, the Enterprise Manager performs these actions:
    • Logs the event.
    • Denies the new connection.
