ZBX_TCP_READ: connection reset by peer

[shoong]

Hi Guys,

Long time lurker and I've usually been able to find my answer based on previous posts. However, I can't figure this one out.

• CentOS 6.5
• Zabbix Server 2.4.2

I added the agent to my local windows box to test before I start adding it to every system we currently have. I have configured the file on the agent:

• Server: 127.0.0.1
• ServerActive: 192.168.72.104 (Zabbix Server IP)

zabbix_agent.log

Under the zabbix web gui

• Host name: *made it a generic name, does this have to match what my computer name is?*
• Groups: Discovered Hosts
• Agent interfaces: IP Address: 192.168.42.179 (this is the IP of my box, I also tried inputting the Zabbix Server IP with no luck)
• Templates: App_Zabbix_agent and ICMP_Ping

I have tried resetting my local box. I also reset my box everytime I made a change. Any help will be appreciated. Let me know if you need any other information.

Check ServerActive setting, I guess you have "zabbix" instead of IP there.

Agent wants to connect to "zabbix:10051" but fails. This may be a DNS problem, zabbix does not resolve to the IP of your Zabbix server.

Also host name in the frontend must match Hostname setting in the agent configuration file if you want active checks to work.

Hi Glebs,

Thanks for your reply. when you say frontend do you mean on the web gui? i changed zabbix to the ip of the host and it now stats host [utl-zabbix01.dev.priv] not found.

i'm assuming i'll have to plug that name in somewhere?

Do I have to set a hostname or can I leave it commented out on the windows agent conf side and CentOS agent conf side?

issue resolved. the hostnames parameter on both my window's box agent conf and centos agent conf had to be the same.
