Asynchronous discovery sensor

The asynchronous discovery sensor is required for asynchronous discovery. IP addresses that are unreachable (cannot be pinged) are candidates for asynchronous discovery. The asynchronous discovery sensor attempts to determine which of the unreachable IP addresses are valid.

For information about asynchronous discovery, see Asynchronous discovery.

In asynchronous discovery, the output of the discovery script is an archive file that contains the discovery results and is stored in a directory on the TADDM server. An unreachable IP address is considered valid if an archive file exists on the TADDM server for that IP address. Based on the content of the archive file, the appropriate sensors are scheduled to process their discovery script output. Sensors then perform discovery by parsing the script output instead of directly accessing the target system, as is done in a nonscript-based discovery.

Configuring the sensor

The asynchronous discovery sensor does not use the access list.

The asynchronous discovery sensor uses the following entries in the collation.properties file:
  • com.ibm.cdb.discover.asd.AsyncDiscoveryResultsDirectory
  • com.ibm.cdb.discover.asd.ProcessUnreachableIPs
  • com.ibm.cdb.tarpath
