real time display of log files - any other ideas?

real time display of log files - any other ideas?

(OP)
I read thread452-566155 re displaying log files in near real time. That thread uses tail (linux) and perl/html forcing the web page to refresh.

Ive got a number of different jobs reading a syslog alarm log file - would like it to be viewable from any other pc on the LAN so I can keep an eye on events via a web browser.

I also update icons on a main alarm web page using javascript/perl also using this heavy refresh technique - need to move to more advanced methods.

Does anyone have any alternatives to this to do this smoother i.e. using java (tcp/udp updates) that uses a stream or other techniques??

Any comments welcome.

Hi

Use server-push :

CODE

#!/bin/bash

echo -e "Content-type: text/html\n"

cat <<EOT
<html>
<body>
<pre>
EOT

tail -f "/path/to/log"
The modern browsers will keep the connection open and render the content as it arrives.

I wrote a bash script just because it is more clear.
