The discovery.conf file contains several settings that you can edit to improve performance during topology discovery. However, changing these values beyond the recommended values can adversely affect the discovery process. These settings include:

  • defaultICMPAutoRetries

  • defaultICMPAutoTimeout

  • defaultSNMPAutoRetries

  • defaultSNMPAutoTimeout

  • defaultRetries

  • defaultTimeout

    The defaultICMPAutoRetries, defaultICMPAutoTimeout, defaultSNMPAutoRetries, and defaultSNMPAutoTimeout settings apply to discovery. These settings do not affect the operation of the ICMP or SNMP poller that polls objects to perform analysis.

    When a timeout occurs because of packet loss in the network, increase the number of retries. If the timeout occurs because the network is slow or the system is busy, increase the value of the timeout.
