[TrapoSAMA]

Hi all!

I have some VM linux machine working fine! but other dont work with Template OS Linux by Zabbix agent active only with Template OS Linux by Zabbix agent and dont why or who. Some tips for checks or debug?

All of them work fine with the previous Template OS Linux

1) Firewall ports are ok you?

• In zabbix-server: telnet zabbix-agent-ip 10050
• In zabbix-agent: telnet zabbix-server-ip 10051

2) ServerActive configuration in the agent has the right parameters (needs the IP from Zabbix-server)?

Hi!

all linux have the same conf and put the custom conf in /etc/zabbix/zabbix_agentd.d/agent.conf
i try with and without firewall activated, ports are open and working but template active dont work . Is possible check why fail if the ports are open and conf is fine?

i try delete host an recreate, reinstall agent with conf and the same result.

Thx

Agent Logs probably in /var/log/zabbix/zabbix_agentd.log if it's not enough you can try to go for a higher DebugLevel in agent configuration.

And look out for zabbix_sender and configure a trapper test item, then you can fire it from host to server to test the communication.

Hi!

i try using zabbix_sender and work i think:

zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -k mysql.queries -o 342.45
Response from "zabbix.domain.com:10051": "processed: 0; failed: 1; total: 1; seconds spent: 0.000025"
sent: 1; skipped: 0; total: 1

echo "- hw.serial.number 1287872261 SQ4321ASDF" | zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -T -i -
Response from "zabbix.domain.com:10051": "processed: 0; failed: 1; total: 1; seconds spent: 0.000029"
sent: 1; skipped: 0; total: 1

I check in both linux VM (with active template and without active template) and the same result

port open and working in both VM, check with telnet.

Thx

It did not work. Failed = 1, now do the same sender and put a -vv in it to see the errors.

How about DebugLevel=5 + AgentLogs? Any news?

lol!

using sender method is more complex, failed with both linux. Activating debuglevel in one linux and change from normal template to active. What need search in log?
