Tuning discovery
After copying the discovery configurations from one of the
IP Availability Manager
installations to the installation, you should consider modifying certain configurations in the discovery.conf
and tpmgr-param.conf files to reduce memory usage and to shorten the discovery time of the . If neither high memory usage nor long discovery time is an issue in your deployment,
you can ignore the following considerations.Consider doing the following to reduce memory usage and to shorten discovery time:
- Increase the number of discovery threads in discovery.confIncrease the number of discovery threads in discovery.conf
- Disable unnecessary discovery probes in discovery.confDisable unnecessary discovery probes in discovery.conf
- Ensure that unnecessary discovery probes are disabled in tpmgr-param.confEnsure that unnecessary discovery probes are disabled in tpmgr-param.confAlso, consider adding the--nodx option to the service command, to reduce memory use by preventing the loading of the libraries that enable codebook correlation and event generation. If necessary, use property subscription to subscribe to DiscoveryError events for UnitaryComputerSystem elements.If memory usage is not an issue, do not add the--nodx option to the service command.
