mod_debug

mod_debug offers various utilities to aid you debug a problem.

debug.show_connections (action)

shows a page similar to the one from mod_status, listing all active connections

debug.show_connections;

By specifying one or more "connection ids" via querystring (parameter "con"), one can request additional debug output for specific connections.

Example

if req.path == "/debug/connections" { debug.show_connections; }

debug.profiler_dump (action)

dumps all allocated memory to the profiler output file if profiling enabled

debug.profiler_dump;

lighttpd2 needs to be compiled with profiler support, and profiling has to be enabled by setting the environment variable LIGHTY_PROFILE_MEM to the path of a target log file.

debug.show_events (action)

shows a plain text list of all events

debug.show_events;

this is a very low level debug tool for developers.

Example

if req.path == "/debug/events" { debug.show_events; }

debug.show_events_after_shutdown (setup)

time in seconds after start of shutdown to log remaining active events

debug.show_events_after_shutdown timeout;
timeout
timeout after which to display events (default: disabled)

this is a very low level debug tool for developers; it shows which event listeners keep lighttpd2 alive when it should stop.

Example

setup { debug.show_events_after_shutdown 5; }
