The logger derives +from log4cpp (http://log4cpp.sourceforge.net/) which is readily +available in most Linux distributions. This is an optional dependency +and GNU Radio will work without it. + +When configuring GNU Radio, the -DENABLE_GR_LOG=On|Off option to cmake +will allow the user to toggle use of the logger on and off. The logger +defaults to "on" and will use log4cpp if it is available. If log4cpp +is not found, the default logging will output to standard output or +standard error, depending on the level of the log message. + +Logging is useful for blocks to print out certain amounts of data at +different levels. These levels are: + +<pre> + DEBUG < INFO < WARN < TRACE < ERROR < ALERT < CRIT < FATAL < EMERG +</pre> + + +The order here determines the level of output. These levels are +hierarchical in that specifying any level also includes any level +above it. For example, when using the Debug level, all Debug and +higher messages are logged and Trace is ignored. + +\subsection configfile Logging Configuration + +The logging configuration can be found in the gnuradio-core.conf file +under the [LOG] section. This allows us fairly complete control over +the logging facilities. The main configuration functions are to set up +the level of the loggers and set the default output behavior of the +loggers. + +There are two default loggers that all gr_block's have access to: +d_logger and d_debug_logger. The first is a standard logger meant to +output simple information about the block while it is running. The +debug logger is meant for debugging purposes and is added to make it +convenient to use a secondary logger that outputs to a different +stream or file. + +The four main configure options are: + +<pre> + log_level = debug + debug_level = debug + log_file = stdout + debug_file = stderr +</pre> + +This establishes the two loggers as having access to all levels of +logging events (DEBUG through EMERG). They are also configured not to +use files but instead output to the console. The standard logger will +output to standard out while the debug logger outputs to standard +error. + +Changing these last two lines to another value will create files that +are used to store the log messages. All messages are appended to the +file. + +When using either standard error or standard out, the messages for the +two different loggers will look like: + +<pre> + gr::log :\<level\>: \<block alias\> - \<message\> + gr::debug :\<level\>: \<block alias\> - \<message\> +</pre> + +When using a file, the only difference in the format is that the +message prefix of "gr::log" or "gr::debug" is not used. Instead, the +time in milliseconds from the start of the program is inserted. + +Remember that a local "~/.gnuradio/config.conf" file can be used to +override any parameter in the global file (see \ref prefs for more +details). + +To use these loggers inside of a GNU Radio block, we use the protected +data members of d_logger and d_debug_logger of gr_block and pass them +to our pre-defined macros: + +\code + GR_LOG_<level>(<logger>, "<Message to print>"); +\endcode + +Where \<level\> is one of the levels as mentioned above, \<logger\> is +either d_logger or d_debug_logger, and \<Message to print\> is the +message we want to output. If we wanted to output an INFO level +message to the standard logger and a WARN level message to the debug +logger, it would look like this: + +\code + GR_LOG_INFO(d_logger, "Some info about the block"); + GR_LOG_WARN(d_debug_logger, "Some warning about the block"); +\endcode + +When this is printed to wherever you are directing the output of the +logger, it will look like: + +<pre> + gr::log :INFO: <block's alias> - Some info about the block + gr::debug :WARN: <block's alias> - Some warning about the block +</pre> + +This provides us information about where the message came from, the +level of the message, and the block that generated the message. We use +the concept of the block's alias which by default (i.e., unless +otherwise set by the user) includes the name of the block and a unique +ID to distinguish it from other blocks of the same type. + +The various logging macros are defined in gr_logger.h. Here are some +simple examples of using them: + +\code + GR_LOG_DEBUG(LOG, "DEBUG message"); + GR_LOG_INFO(LOG, "INFO message"); + GR_LOG_NOTICE(LOG, "NOTICE message"); + GR_LOG_WARN(LOG, "WARNING message"); + GR_LOG_ERROR(LOG, "ERROR message"); + GR_LOG_CRIT(LOG, "CRIT message"); + GR_LOG_ALERT(LOG, "ALERT message"); + GR_LOG_FATAL(LOG, "FATAL message"); + GR_LOG_EMERG(LOG, "EMERG message"); +\endcode + +If the logger is not enabled, then these macros become nops and do +nothing (and d_logger and d_debug_logger are NULL pointers). If +logging is enabled but the log4cpp library is not found, then TRACE, +INFO, and NOTICE levels go to stdout and the rest to stderr. + + +\subsection adv_config Advanced Configuration Options + +If not using the simplified settings discussed above, where we can +direct the logger messages to either a file or one of the standard +outputs, we must use a more complicated configuration file. We do this +by specifying the "log_config" option in the [LOG] section. The +log4cpp documentation will provide more information on how +configuration works and looks. Mostly, a default configuration script +provided with GNU Radio can be used. After installation, the default +configuration script is located at: + +<pre> + $prefix/etc/gnuradio/gr_log_default.xml +</pre> + +For the following examples, we will assume that our local +"~/.gnuradio/config.conf" looks like this: + +\code +[LOG] +log_config = /opt/gr/etc/gnuadio/gr_log_default.xml +log_level = debug +debug_level = Off +\endcode + +Inside of the XML default configuration file, we define the parameters +for the two logger's, the standard logger the separate debug logger. + +If the levels of the two loggers are specified in our configuration +file, as in the above example, these levels override any levels +specified in the XML file. Here, we have turned on the standard logger +(d_logger) to all levels and turned off the debug logger +(d_debug_logger). So even if the debug logger is used in the code, it +will not actually output any information. Conversely, any level of +output passed to the standard logger will output because we have +turned this value to the lowest level "debug." + +If both an XML configuration file is set and the "log_file" or +"debug_file" options are set at the same time, both systems are +actually used. So you can configure file access and the pattern +through the XML file while also still outputting to stdout or stderr. + + +\section advlog Advanced Usage + +The description above for using the logging facilities is specific to +GNU Radio blocks. We have put the code necessary to access the +debugger into the gr_block parent class to simplify access and make +sure all blocks have the ability to quickly and easily use the logger. + +For non gr_block-based code, we have to get some information about the +logger in order to properly access it. Each logger only exists once as +a singleton in the system, but we need to get a pointer to the right +logger and then set it up for our local use. The following code +snippet shows how to do this to get access to the standard logger, +which has a root of "gr_log." (access to the debug logger is similar +except we would use "gr_log_debug." in the GR_LOG_GETLOGGER call): + +\code + gr_prefs *p = gr_prefs::singleton(); + std::string log_file = p->get_string("LOG", "log_config", ""); + std::string log_level = p->get_string("LOG", "log_level", "off"); + GR_CONFIG_LOGGER(log_file); + GR_LOG_GETLOGGER(LOG, "gr_log." + "my_logger_name"); + GR_LOG_SET_LEVEL(LOG, log_level); +\endcode + +This creates a pointer called LOG (which is instantiated as a +log4cpp:LoggerPtr in the macro) that we can now use locally as the +input to our logging macros like 'GR_LOG_INFO(LOG, "message")'. + +*/ diff --git a/docs/doxygen/other/main_page.dox b/docs/doxygen/other/main_page.dox index e7d4685f75..8895cd552d 100644 --- a/docs/doxygen/other/main_page.dox +++ b/docs/doxygen/other/main_page.dox @@ -39,6 +39,7 @@ More details on packages in GNU Radio: \li \ref page_vocoder More details on GNU Radio concepts: +\li \ref page_logger \li \ref page_pmt \li \ref page_msg_passing \li \ref page_metadata diff --git a/gnuradio-core/CMakeLists.txt b/gnuradio-core/CMakeLists.txt index b277103547..2bbb8570db 100644 --- a/gnuradio-core/CMakeLists.txt +++ b/gnuradio-core/CMakeLists.txt @@ -44,6 +44,7 @@ GR_REGISTER_COMPONENT("gnuradio-core" ENABLE_GR_CORE ) include(GrMiscUtils) + GR_SET_GLOBAL(GNURADIO_CORE_INCLUDE_DIRS ${CMAKE_CURRENT_SOURCE_DIR}/src/lib/runtime ${CMAKE_CURRENT_BINARY_DIR}/src/lib/general @@ -59,13 +60,17 @@ GR_SET_GLOBAL(GNURADIO_CORE_INCLUDE_DIRS ${CMAKE_CURRENT_BINARY_DIR}/src/lib/swig ${CMAKE_CURRENT_SOURCE_DIR}/src/lib/swig ${CMAKE_CURRENT_SOURCE_DIR}/src/lib/hier + ${CMAKE_BINARY_DIR} ) +list(APPEND GNURADIO_CORE_INCLUDE_DIRS ${CMAKE_BINARY_DIR}) + GR_SET_GLOBAL(GNURADIO_CORE_SWIG_INCLUDE_DIRS ${GNURADIO_CORE_INCLUDE_DIRS} ${CMAKE_CURRENT_SOURCE_DIR}/src/lib/swig ${CMAKE_SOURCE_DIR}/gruel/src/swig ${CMAKE_BINARY_DIR}/gruel/src/swig + ${CMAKE_BINARY_DIR} ) ######################################################################## @@ -107,12 +112,26 @@ CPACK_COMPONENT("core_swig" DEPENDS "gruel_swig;core_python;core_devel" ) +# Setup configure file +configure_file( + ${CMAKE_CURRENT_SOURCE_DIR}/gnuradio-core.conf.in + ${CMAKE_CURRENT_BINARY_DIR}/gnuradio-core.conf +@ONLY) + install( - FILES gnuradio-core.conf + FILES ${CMAKE_CURRENT_BINARY_DIR}/gnuradio-core.conf DESTINATION ${GR_PREFSDIR} COMPONENT "core_runtime" ) +if(ENABLE_GR_LOG AND HAVE_LOG4CPP) +install(FILES + ${CMAKE_CURRENT_SOURCE_DIR}/gr_log_default.xml + DESTINATION ${GR_CONF_DIR}/gnuradio + COMPONENT "core_runtime" +) +endif(ENABLE_GR_LOG AND HAVE_LOG4CPP) + ######################################################################## # Add subdirectories ######################################################################## diff --git a/gnuradio-core/gnuradio-core.conf b/gnuradio-core/gnuradio-core.conf deleted file mode 100644 index d575d1dc8a..0000000000 --- a/gnuradio-core/gnuradio-core.conf +++ /dev/null @@ -1,14 +0,0 @@ -# This file contains system wide configuration data for GNU Radio. -# You may override any setting on a per-user basis by editing -# ~/.gnuradio/config.conf - -[DEFAULT] - -verbose = False - -# The maximum number of messages a block will store up before pruning -# the queue by popping messages from the front. -max_messages = 100 - -[PerfCounters] -on = False diff --git a/gnuradio-core/gnuradio-core.conf.in b/gnuradio-core/gnuradio-core.conf.in new file mode 100644 index 0000000000..25abedb253 --- /dev/null +++ b/gnuradio-core/gnuradio-core.conf.in @@ -0,0 +1,31 @@ +# This file contains system wide configuration data for GNU Radio. +# You may override any setting on a per-user basis by editing +# ~/.gnuradio/config.conf + +[DEFAULT] +verbose = False + +# The maximum number of messages a block will store up before pruning +# the queue by popping messages from the front. +max_messages = 100 + + +[LOG] +# Levels can be (case insensitive): +# DEBUG, INFO, WARN, TRACE, ERROR, ALERT, CRIT, FATAL, EMERG +log_level = debug +debug_level = emerg + +# These file names can either be 'stdout' to output to standard output +# or 'stderr' to output to standard error.
