Option to print log level in NS_LOG messages
Last modified: 2013-12-12 17:46:41 UTC
Created attachment 1438 [details] diff of src/core/model/log.{h,cc} It'd be nice if there was an option to print the LOG_LEVEL (severity) in the message, similar to prefixing the time, node, or function. This patch enables NS_LOG="*=all|prefix_level" and prints as [ERROR] error message [WARN] warn message [DEBUG] debug message [INFO] info message [LOGIC] logic message $ NS_LOG="*=all|prefix_all" ./waf --run scratch-simulator Scratch Simulator ScratchSimulator:main(): [ERROR] error message ScratchSimulator:main(): [WARN] warn message ScratchSimulator:main(): [DEBUG] debug message ScratchSimulator:main(): [INFO] info message ScratchSimulator:main(function) ScratchSimulator:main(): [LOGIC] logic message (I added NS_LOG_ERROR ("error message"), etc to scratch-simulator.cc, for illustration.) If this patch is accepted, I volunteer to amend the tutorial.
Also added "prefix_all", as you'll see in the diff.
Relabel to core component.
ok for commit. Can you please update this bug report with the commit changeset once you are done ?
Commit 9c0cc3997ece http://code.nsnam.org/ns-3-dev/rev/9c0cc3997ece I volunteered to write a manual chapter, but that's going to have to wait, along with some ideas for wildcards...
This has been reraised in bug 1531.
I'm reopening this, as this doesn't seem to behave as expected as of ns-3.16: NS_LOG="*=all|prefix_all" ./waf --run first nor this: NS_LOG="*=all|prefix_all" ./waf --run scratch-simulator (prefix levels are not printed out) Also, the scratch-simulator.cc program was not patched as described in the tracker.
actually, after further testing and reading the patch, it seems to be working since it is limited to these levels: + labels[LOG_ERROR] = "ERROR"; + labels[LOG_WARN] = "WARN"; + labels[LOG_DEBUG] = "DEBUG"; + labels[LOG_INFO] = "INFO"; + labels[LOG_LOGIC] = "LOGIC"; but I'll leave this open until documentation is completed.
