The Oracle Trace File Analyzer (TFA) Collector is a tool for targeted diagnostic collection that simplifies diagnostic data collection for Oracle Clusterware, Oracle Grid Infrastructure, and Oracle RAC systems. TFA collects and packages diagnostic data and also has the ability to centralize and automate the collection of diagnostic information.
TFA is installed into the Oracle Grid Infrastructure home when you install, or upgrade to, Oracle Database 12c release 1 (12.1.0.2). The TFA daemon discovers relevant trace file directories and then analyzes the trace files in those directories to determine their file type (whether they are database trace or log files, or Oracle Clusterware trace or log files, for example) and the first and last timestamps of those files. TFA stores this data in a Berkeley database in the Grid home owner's ORACLE_BASE directory.
The TFA daemon periodically checks for new trace directories to add, such as when a new database instance is created, and also periodically checks whether the trace files metadata need updating. TFA uses this metadata when performing diagnostic data collections.
TFA can perform diagnostic collections in two ways, either on demand or automatically:
Use tfactl set to enable automatic collection of diagnostics upon discovery of a limited set of errors in trace files

The tfactl diagcollect command collects trimmed trace files for any component and specific time range
