LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR, LOG_WARNING, LOG_NOTICE, LOG_INFO, LOG_DEBUG. The module defines the following constants: Priority levels (high to low): The function LOG_UPTO(pri) calculates the mask for all priorities up to and including pri. The function LOG_MASK(pri) calculates the mask for the individual priority pri. Calls to syslog() with a priority level not set in maskpri are ignored. Set the priority mask to maskpri and return the previous mask value. For example, openlog() will be called on the first syslog() call (if openlog() hasnвЂ™t already been called), and ident and other openlog() parameters are reset to defaults. This causes the module to behave as it does when initially imported. Reset the syslog module values and call the system library closelog(). The optional facility keyword argument (default is LOG_USER) sets the default facility for messages which do not have a facility explicitly encoded. The optional logoption keyword argument (default is 0) is a bit field вЂ“ see below for possible values to combine. The optional ident keyword argument is a string which is prepended to every message, and defaults to sys.argv with leading path components stripped. syslog() will call openlog() with no arguments if the log is not currently open. Logging options of subsequent syslog() calls can be set by calling openlog(). If openlog() has not been called prior to the call to syslog(), openlog() will be called with no arguments. If the facility is not encoded in priority using logical-or ( LOG_INFO | LOG_USER), the value given in the openlog() call is used. The optional priority argument, which defaults to LOG_INFO, determines the message priority. Each message is tagged with a priority composed of a facility and a level. A trailing newline is added if necessary. Send the string message to the system logger. The module defines the following functions: syslog.syslog(message) syslog.syslog(priority, message) A pure Python library that can speak to a syslog server is available in the logging.handlers module as SysLogHandler. This module wraps the system syslog family of routines.

#PYTHON SYSLOG CLIENT MANUAL#

Refer to the Unix manual pages for a detailed description of the syslog facility. '.date('M j H:m:s').' '.gethostname().' '.This module provides an interface to the Unix syslog library routines. ndto('' + t + ' ' + host + ' ' + line, (server, port)) PHP #!/usr/bin/php Sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) $time = strftime '%b %d %H:%M:%S', localtime Message = '' + time + ' ' + host + ' ' + line.chomp We can do the same thing in other scripting languages too Ruby #!/usr/bin/ruby Set it to log every 10 seconds and make a quick graph: while `true` do uptime |. Just for fun, IвЂ™ll extract the load average (if you want to know all the other things you can do with extracted fields visit the Log Insight Developer Center page )

For instance, letвЂ™s log the output of the system вЂuptimeвЂ™ command with uptime |. That will let us send something in through the standard input and send it to Log Insight over syslog. Super easy to do by hand, letвЂ™s turn that into a handy bash script I like to call logger.sh: #!/bin/bashД®cho '$date $host $message' | nc -w 1 -u $server $port You can do this with NetCat for instance: nc -u 514 Simply construct a UDP packet with that payload and send it to port 514 on your Log Insight server. The timestamp, hostname, tag and message are just as they appear in the logs, so what you send to the syslog port looks like this: Month DayOfMonth Hour:Minute:Second Hostname Tag: Message

#PYTHON SYSLOG CLIENT CODE#

The priority is a number that codes for the facility and the вЂњlevel surrounded by brackets, weвЂ™ll use in our examples and you can find the complete code table on Wikipedia. IвЂ™ll show you how easy it is to send syslog messages to Log Insight from a handful of scripting languages.ДЇirst, the basics: a syslog message is made from the priority, timestamp, hostname, tag and message вЂ“ in that order вЂ“ of the line you want to log. If you are wondering how syslog became so popular, it is because it is easy.

#PYTHON SYSLOG CLIENT SOFTWARE#

Now it is available for every operating system with commercial software available from multiple vendors. ItвЂ™s hard to believe that the syslog protocol was only a part of sendmail at first. Why did the Log Insight team choose syslog, invented way back in the 80s, as the input protocol for Log Insight? The 80s was the decade that brought us CD-ROMs, Doppler Radar and Digital Cell Phones.
