An executing computer program is debugged by the use of an events table comprising a plurality of table entries, each table entry comprising an event description describing an event occurring during execution of the executing computer program; a debugger description specifying a debugger to be invoked to debug the executing computer program upon an occurrence of the event; and debugger options to be passed to the debugger upon invocation of the debugger. Debugging the executing computer program comprises monitoring for the event; detecting the event; gathering event information beyond the event description; searching the event table responsive to the detection of the event; finding the table entry corresponding the event; responsive to the finding of the table entry, invoking the debugger specified by the debugger description in the table entry corresponding the event; passing the debugger options to the debugger; and passing the event information to the debugger. A first table entry may be used to invoke a first debugger responsive to a first event, and a second table entry may be used to invoke a second debugger responsive to a second event.
