Monitoring URL - Trigger for "Temporary failure in name resolution"

[anjo_ed]

Hello, how are you doing ?

So, I have a Dev environment with the follow configuration:
- Zabbix 6.4
- Ubuntu 22.04
- 10 hosts: 2 ubuntu and 8 URLs


My URLs were create using this parameters:

body:
jsonrpc: "2.0"
method: "item.create"
params:
name: "Check {{ item }}"
key_: "web.page.get['{{ item }}']"
hostid: "{{ zabbix_template_id }}"
type: 19 # HTTP agent
value_type: 3 # Numeric Unsigned
interfaceid: 0 # Não necessário para HTTP agent
tags:
- tag: "URL"
value: "{{ item }}"
delay: "30s"
url: "{{ item }}"
status_codes: "200"
follow_redirects: 1
output_format: 1 # Extracted JSON
posts: ""
headers:
Content-Type: "application/json"
verify_host: 0
verify_peer: 0
allow_traps: 0
auth: "{{ zabbix_api_token }}"
id: 1

Where ITEM is an URL; the type is HTTP Agent
Here we have an example:






So, it is working when the domain exists, I mean, when it is resolving and it is not returning an error like: "Temporary failure in name resolution". However, How Can I monitor this situation ? When is the domain not resolving ? How could I detect it and create an alert for it ? Is there a way ? Maybe I am using the wrong type to monitor it ?

Thanks!

Hello.

I didn't find a solution yet. Maybe the solution is to use curl together with the system.run ?
