NAME¶

Usage¶

If you want to trace how and if the backend is called:

kdb mount file.ysp user/trace_point your_storage_plugin tracer

So now we can trace whats below your trace point.

kdb ls user/trace_point

Ok, no tracer is called because resolver immediately told that there is no file.

kdb get user/trace_point
Did not find key

Ok, same conclusion.

kdb set user/trace_point hello
create a new key user/trace_point with string "hello"
tracer: set(0xd34cc0, user/trace_point): user/trace_point 1
tracer: set(0xd34cc0, user/trace_point): user/trace_point 1
tracer: set(0xd34cc0, user/trace_point): user/trace_point 1

Now the 3 placements in set are called.

kdb get user/trace_point
tracer: get(0x22e1cc0, user/trace_point): 0
tracer: get(0x22e1cc0, user/trace_point): 0
hello

Now the 2 placements in get are called.

Module Loading¶

Will not log when loaded as module (config /module present), unless /logmodule is set:

kdb check -c "logmodule=" tracer
