External Site Monitoring

Hi,

Currently looking into ways to monitor external sites and the response times that an end user would see for these.

Currently looking to to monitor both ports 443 and 80 (note I do not own the sites, I just want to be able to see what the response time to the sites is using the network. Connections are proxied, hence it helps to see if there are issues with clients on VPN's or issues within a network)

I can see from the CLI by doing either of the following.

ncat -v -z google.com 443 Ncat: Version 7.80 ( https://nmap.org/ncat ) Ncat: Connected to 216.58.223.206:443. Ncat: 0 bytes sent, 0 bytes received in 0.08 seconds. time nc -v -z google.com 443 google.com [216.58.223.206] 443 (https) open real 0m0.039s user 0m0.002s sys 0m0.005s 

However, I'm unsure on how i can graph the results from these tests.

Does anyone have experience of doing this or have it enabled, if so i'd like to hear about it if possible.

My thought process would the data can be pushed into a log file that gets ingressed into syslog and then we can graph based on the syslog messages. But again, unsure on how to do this.

If this is not he correct sub for this type of question, can I be pointed to one that may help.

Thanks in advance for any help and replies to this.
