Each 'call' has an associated record in 'call_paths'. +# 'calls_paths' is only created when the 'calls' option to this script is specified. +# +# branch_types +# +# 'branch_types' provides descriptions for each type of branch. +# +# comm_threads +# +# 'comm_threads' shows how 'comms' relates to 'threads'. +# +# comms +# +# 'comms' contains a record for each 'comm' - the name given to the executable that is running. +# +# dsos +# +# 'dsos' contains a record for each executable file or library. +# +# machines +# +# 'machines' can be used to distinguish virtual machines if virtualization is supported. +# +# selected_events +# +# 'selected_events' contains a record for each kind of event that has been sampled. +# +# symbols +# +# 'symbols' contains a record for each symbol. Only symbols that have samples are present. +# +# threads +# +# 'threads' contains a record for each thread. +# +# Views: +# +# Most of the tables have views for more friendly display.
