Custom DNS sensor

Votes:

0

I need a custom DNS sensor for two reasons, per below. I can't seem to make the built-in typical DNS sensor work for me...

1) Track if my domain becomes blacklisted in a RBL... Query a certain DNS server if example.com reports 127.0.0.x Then have PRTG generate an alert if the response = any of the following, or perhaps just one of the following... 127.0.0.2 127.0.0.3 127.0.0.4 127.0.0.5 127.0.0.10 127.0.0.11

2) Track the number of users detected on my hotspot... When using DNS Redirector the number of clients online is reported in the answer of a special DNS lookup: online.dnsredirctrl.com 0.0.0.1 = one client is online 0.0.0.2 = two clients are online 0.0.1.1 = eleven clients are online ...etc. Then graph this as the number online in a PRTG graph.

Possible?? Please :-)

Hello,

I'm afraid such a sensor is not very likely to come. We would recommend to setup a script which runs as a Custom Script Sensor.

Best Regards.
