Discovery stitcher rules

Use these stitcher rules for reference when you are working with discovery stitchers.

AnalyzeSQLStats()
The AnalyzeSQLStats(); stitcher rule analyzes an SQLite database or a single specified table in that database and ensures that SQLite has up-to-date statistics on its database tables from which it can make efficient SQL query plans. This ensures that any subsequent SQL select queries made using the data in the tables are efficient.
DiscoReadConfig()
The DiscoReadConfig rule tells the Discovery Engine, ncp_disco, to reread its configuration files.
DncimRecordsDone()
The DncimRecordsDone(); rule notifies the discovery that a RecordToDNCIMDb() rule session has completed and instructs the discovery to commit any outstanding SQL actions.
DiscoRefresh()
The DiscoRefresh(); stitcher rule sends a refresh message to the Helper server, finders, or agents connected to the discovery process. The effect of the refresh message will vary depending on the process and the arguments.
DiscoRetrieveClass()
The DiscoRetrieveClass(); stitcher rule is used to retrieve the class of a discovered device during the discovery process, so that users can determine device type while the discovery is still running.
DiscoSendOQLToFinder()
The DiscoSendOQLToFinder(); stitcher rule sends OQL results to the finder subprocess from the discovery. This is commnly used as part of the feedback process, where the ping finder is seeded with subnets and IP addresses discovered during the course of the network discovery.
DncimUpdate()
The DncimUpdate(); rule updates a record in a specified table in the dNCIM database and sets a flag so that the updated row will be broadcast in the next call to the BroadcastToModel(); rule. The DncimUpdate(); rule can also be called omitting the optional record to force a broadcast of the row even if no other changes are made. This is useful when a row has been removed as part of a cascaded delete.
EnumerationLookup()
The EnumerationLookup(); rule retrieves a value from the DNCIM enumeration table. The data in the enumeration table is downloaded when the Discovery engine, ncp_disco, is first started and then accessed directly by the rule, thereby enabling fast data retrieval.
RecordToDncimDb()
The RecordToDncimDb(); takes a record and passes it through the mappings in the ModelNcimDb.cfg and DbEntityDetails.cfg configuration files. These mappings are used to populate multiple dNCIM tables and create new objects.
StitcherProfiling()
The StitcherProfiling(); stitcher rule sets the discovery process to log the time each stitcher takes to complete and the number of executions for each stitcher during a discovery cycle. The logging results help diagnose discovery issues. This rule is set in the FinalPhase stitcher.
