start tracing by using the schnell script ;) write the trace pattern in double quotes, have a look at the Redbug Trace Pattern examples.

Example 1:

Trace all ets lookups where the table is my_table, and stop when either a time of 10s has been reached, or a maximum of 1000 messages.

./start_erltea.sh 10 1000 "ets:lookup(Tbl, _) when Tbl == my_table -> return"

Example 2:

Trace all ets lookups and trace all ets:delete calls for 60s or 100 messages

./start_erltea.sh 60 100 "ets:lookup/2 -> return" "ets:delete/1 -> return" "ets:delete/2 -> return"
