Hi, Torsten Curdt <tcurdt@vafer.org> [20060923 09:35:30 +0200]:
2. you can 'tune in' to the logging messages you want from anywhere
Haha! :-)
I think its the latter that you would be interested in particularly. Although I have multicast logging setup here at work I have yett to get around to write the 'tuning in' perl script that will stream the logs to the local machine, so what you would type on the developer machines is:
$ ./syslog-mc.pl 239.239.12.13 514 | grep cheese
That would be awesome! Exactly what I was after. Was more thinking about a standard tcp/udp connection but why not multicast...
Well you will need multicast support if you have to cross subnet's/routers however if its all on the same subnet you could get away with the recent broadcast support added and pick your particular log by port number. The disavantage of this is that *every* machine on the subnet will receive the packets whether they want them or not. The multicast approach obviously is cleaner for several reasons, also if you have developers wanting to do this from across a VPN then multicast is the only way to go about doing this.
which would display live all the lines with cheese that are being streamed to the multicast address 239.239.12.13 (port 514).
If you grovel suitably I'll get around to writing[1] the tuning in script sooner rather than later ;)
Hehehe
Is this what you are after? syslog-ng would still run on the logging box but you would broadcast to multicast groups your streams.
This sounds pretty good! ...I will check with my folks and then might begin to grovel ...or to contribute ;-)
Its actually rather straight forward to do and its only something I have not done yet as the logging cluster is not being extensively used yet. If someone else has a use for it then I'll get around to it sooner rather than later. However if you cannot wait it seems someone has made a multicast enabled netcat: http://code.google.com/p/mnc/ You will be able to use this to do something very similar, it also says that it works under windoze aswell. Cheers Alex
