+Requirements:

+- a webserver with activated PHP (apache, nginx or whatever) – PHP 7.x is ok
+
+ 
+
+Modifikation/Extension of hbmonitor (red lines need to add in script web_tables.py) – we log if a call is ended (I think it’s better as start) Please check permissions for writing the logfile in target folder !

+The line:

+    if int(float(p[9])) > 2:
+
+we can skip show in last heard for exmaple from MASTER with name OPB-Link
+
+    if p[3] != 'OPB-Link' and int(float(p[9])) > 2:
+
+
+I recommed to shorten the lastheard.log from time to time (I cut every day to 550 lines, longer values maybe extend the load time and parsing) with this script lh_shorten.sh:
+
+#!/bin/bash
+mv /var/www/html/lastheard.log /var/www/html/lastheard.log.save
+/usr/bin/tail -550 /var/www/html/lastheard.log.save > /var/www/html/lastheard.log
+mv /var/www/html/lastheard.log /var/www/html/lastheard.log.save
+/usr/bin/tail -550 /var/www/html/lastheard.log.save > /var/www/html/lastheard.log
+
+
+Call this script with crontab for everyday use.
+
+Put this file in /etc/cron.d/daily
+
+
+Call the website with http://[YOUR_HOST/log.php it runs with a refresh/reload time of 30sec, change the script for other timeset.

+PS 
+Thank you, Heiko, who shared the lastheard code
+The attached version of web_tables.py contains the display in the column of group names
