TACACS & Radius Server Monitoring

@Michael Rodrigues I had a similar thought. Downloaded tactest from tacacs.net. The cli is straightforward to use. This can be loaded on the primary and backup collectors and run from the script you've mentioned. If we don't figure out an elegant way to test via groovy we will use this method for both tacacs and radius. 

@Dennis Walcott I've done something similar in another monitoring tool in a past life. I used a script that called a radius test client and made a request directly to the RADIUS server. Parse the results and return a simple 1 or 0 for failure or success.

I would probably go with a DataSource over a webcheck in this case.

You can use Expect to run the radius test client if it's installed on your collector.

@Michael Rodrigues Thank you for the quick response. Your suggestion of using DataSource over webcheck makes sense. I have taken a look at using Expect, but after reading through the help documents I decided to engage LogicMonitor Support and possibly Professional Services. I will update this post once I have direction or a working solution.

@Dennis Walcott thought of a codeless way to do it.

If you have a command line utility that allows you to test RADIUS (I used radtest from freeradius) you can just install it on your collector and call it with the "upload script" type Datasource.

Presumably the cli utility will give you back something you can easily regex for in a datapoint, "SUCCESS" or "FAILURE" gets printed out if I remember correctly.
