Detailed Description

System logging access functions using SYSLOG protocol.

The server supports standard Linux syslog access and also supports vendort-provided syslog access APIs.

Function Documentation

◆ cvt_level2syslog_prio()

int cvt_level2syslog_prio ( log_debug_t  level)

Convert from log_debug (native) level to syslog priority.

Parameters
levelNative debug level
Returns
Mapping to syslog priority (see syslog.h)
Here is the caller graph for this function:

◆ log_syslog_append()

void log_syslog_append ( boolean  recursive,
log_debug_t  level,
log_debug_t  sub_level,
const char *  fstr,
va_list  args 
)

Append formatted string output to the internal syslog log buffer.

Parameters
recursiveTRUE means this is a recursive callback from print_backtrace()
levelinternal logger "screening" level
sub_levelinternal logger functional (content) level
fstrformat string in printf format
argsany additional arguments for printf
Here is the call graph for this function:

◆ log_syslog_cleanup()

void log_syslog_cleanup ( void  )

Cleanup syslog related logging state, if any.

Note: Invocation should be delayed to the LAST POSSIBLE MOMENT. This is because the various cleanup routines often want to log errors/warnings/info as well various debugs using standard logging.

Here is the call graph for this function:
Here is the caller graph for this function:

◆ log_syslog_close()

void log_syslog_close ( void  )

Close down syslog connection.

Here is the caller graph for this function:

◆ log_syslog_common()

void log_syslog_common ( boolean  recursive,
log_debug_t  level,
log_debug_t  sub_level,
const char *  fstr,
va_list  args 
)

Generate a log entry destined for vendor specific processing.

Parameters
recursiveTRUE means this is a recursive callback from print_backtrace()
levelYumaPro log level
sub_levelYumaPro log sub-level
fstrformat string in printf format
argsany additional arguments for printf
Here is the call graph for this function:

◆ log_syslog_connect()

void log_syslog_connect ( void  )

Connect to syslog output stream via openlog()

Here is the caller graph for this function:

◆ log_syslog_connected()

boolean log_syslog_connected ( void  )

Return syslog connect status.

Returns
TRUE if connected to syslog deamon
Here is the caller graph for this function:

◆ log_syslog_flush()

void void log_syslog_flush ( void  )

Flush contents of internal buffer to vendor logging system.

Here is the call graph for this function:
Here is the caller graph for this function:

◆ log_syslog_send()

void log_syslog_send ( log_debug_app_t  app,
log_debug_t  level,
const char *  fstr,
  ... 
)

Send log data to syslog via vsyslog()

Parameters
appYumaPro application (such as netconfd-pro or yangcli-pro) This info is already known to syslog via the connect.
levelYumaPro log message level. This will be translated appropriately into a syslog equivalent
fstrstart ptr to format string
...va_list

◆ log_util_flush()

void log_util_flush ( syslog_msg_desc_t desc)

Flush contents of internal buffer to external logging system.

Parameters
descpointer to a syslog msg descriptor to flush
Here is the caller graph for this function:

◆ log_util_init_buf()

void log_util_init_buf ( syslog_msg_desc_t dp)

Initialize the contents of an internal log buffer descriptor.

Parameters
dpaddr of descriptor
Here is the caller graph for this function:

◆ log_util_logbuf_append()

void log_util_logbuf_append ( syslog_msg_desc_t desc,
log_debug_app_t  app,
log_debug_t  level,
log_debug_t  sub_level,
const char *  fstr,
va_list  args 
)

Append formatted string output to an internal log buffer.

Parameters
descPointer to syslog msg buffer descriptor
appYumaPro app (like netconfd-pro or yangcli-pro). This will be (or has been) translated by vendor or syslog into an appropriate equivalent.
levelinternal send priority
sub_levelinternal content priority
fstrformat string in printf format
argsany additional arguments for printf
Here is the caller graph for this function:

◆ log_util_logbuf_common()

void log_util_logbuf_common ( syslog_msg_desc_t desc,
log_debug_app_t  app,
log_debug_t  level,
log_debug_t  sub_level,
const char *  fstr,
va_list  args 
)

Send formatted string output to an internal log buffer.

Parameters
