    Windows Local Host "Availability" shows red

    Hi Everyone,

    I am new to Zabbix and i want to test some monitoring capabilities on my local host. I have added my laptop as a host on Zabbix and to my knowledge it looks like I added it correctly, but I keep seeing a red "Availability" icon instead of a green one. I have installed the Zabbix agent to my machine and the service is running, I have also checked my Firewall Outbound rules and can see the Zabbix 10050 port.

    The message I get on the red icon is as follows (Get Value from agent failed: cannot read response: cannot read from socket: [104] connection reset by peer)

    Can anyone maybe guide me in the right direction? maybe I am missing something?

    Kind Regards

    We have not enough information to answer
    But after you installed zabbix agent you must set Server (which Server can access zabbix) and ServerActive (which zabbix servers agents will send data in active mode) parameters in zabbix agent configuration file and restart agent.
    Second open firewall of course oru se Active checks. In case of active checks make sure hostname in zabbix server and agent match.

      You seem to say you're running Windows. So where's your Zabbix server? Have you got one?
      I presume you installed the Zabbix Agent (2) using the MSI. If so, that will have created rules in Windows Firewall.

      What is the value of ServerActive=
      in C:\Program Files\Zabbix Agent 2\zabbix_agent2.conf

        Apologies for any confusion, so we have a dedicated server that was spun up for Zabbix, and then I added my windows laptop on Zabbix as a Host/resource just to see what metrics I can get. I did download and install the Zabbix agent on my laptop and can see the agent service running.

        I can also see the port 10050 on my laptop Outbound rules (which I believe I should see)

        The Value I have for "ServerActive=" is a IP address.

        Kind Regards

          Right, from PowerShell on the laptop, do a Test-NetConnection -Computername zabbixserverIPaddress -Port 10051
          It sounds like a connectivity / latency issue. You may need to look at it from a network perspective (firewall?)

          You will also need to assign at least one template to the host (laptop) in Zabbix.
