3 Nearly all NoBug Macros emit some log message. NoBug gives the user fine
4 grained control over these log messages to display only interesting information
5 without loosing details.
7 Log messages are routed to different destinations which are:
10 The underlying storage backend. Messages are appended to the
11 end of the buffer, overwriting older messages at the front of
12 the buffer. NoBug comes with a highly efficient ringbuffer
13 implementation. This ringbuffer is temporary by default but
14 can be made persistent on disk which can be inspected with the
18 This is either just stderr or if running under a supported
19 debugger then its facilities to print messages will be used.
22 The user can open files for log messages.
25 Messages are send to the standard system logging daemon.
28 There is are hooks which allows the programmer to catch logmessages and
29 display them in a application defined way.
31 Each logmessage has a priority describing its severity in the same way as
34 All non-fatal messages are associated with a programmer defined flag describing
35 the source of the message (subsystem, module, ...).
37 Putting it all together: A user can define which source/flag shall be logged at
38 what priority level and to which destination. To make this all easier NoBug
39 tries to give reasonable defaults.
