Format string:
%(class)s Calling class the function belongs to, else empty
%(date)s Date using Logger.date_format, see time module
%(domain)s Full Domain: %(module)s.%(class)s.%(function)s
%(file)s Filename of the module
%(function)s Function name, empty in __main__
%(label)s Label according to log function call from Logger.label
%(level)d Internal logging level
%(line)d Line number in module
%(module)s Module name
%(message)s Log message
Standard levels:
FATAL Fatal error messages
ERROR Error messages
WARNING Warning messages
INFOx, x in [1..5] Information
DEBUGy, y in [1..10] Debug messages
NO_INFO No info output
NO_DEBUG No debug output
INFO_MAX Maximum info level
DEBUG_MAX Maximum debug level
x and y depend on info_max and debug_max from Logger class
initialization. See __init__ function.
Default logging targets:
stdout Logs to stdout
stderr Logs to stderr
syslog Logs to syslog
Additional arguments for logging functions (fatal, error, warning, info
and debug):
nl Disable newline at the end with nl=0, default is nl=1.
fmt Format string for this logging entry, overloads global format
string. Example: fmt="%(file)s:%(line)d %(message)s"
nofmt Only output message with nofmt=1. The nofmt argument wins over
the fmt argument.
Example:
from logger import log
log.setInfoLogLevel(log.INFO1)
log.setDebugLogLevel(log.DEBUG1)
for i in range(1, log.INFO_MAX+1):
log.setInfoLogLabel(i, "INFO%d: " % i)
log.setFormat("%(date)s %(module)s:%(line)d [%(domain)s] %(label)s: "
"%(level)d %(message)s")
log.setDateFormat("%Y-%m-%d %H:%M:%S")
fl = FileLog("/tmp/log", "a")
log.addInfoLogging("*", fl)
log.addDebugLogging("*", fl)
log.addInfoLogging("*", log.syslog, fmt="%(label)s%(message)s")
log.debug3("debug3")
log.debug2("debug2")
log.debug1("debug1")
log.info2("info2")
log.info1("info1")
log.warning("warning\n", nl=0)
log.error("error\n", nl=0)
log.fatal("fatal")
log.info(log.INFO1, "nofmt info", nofmt=1)
