Thank you for your reply jan.garaj. Problem is that I don't have any agent log file in /var/log/zabbix-agent and in /tmp/zabbix_agentd.log (this location is in my zabbix_agentd.conf file). I have only the log file of server and it says about agent this

Code:

Item [Zabbix server:net.if.in[eth1,bytes]] error: Get value from agent failed: Cannot connect to [127.0.0.1:10050] [Connection refused$

This are my agent files.

Your agent cannot start - agent is not in "ps -aux | grep zabbix".
Set ListenIP=0.0.0.0 in server configuration - server will work on all network interfaces (also 127.0.0.1) and restart server.
Try disable firewall.
Check write permission for user zabbix to /var/tmp /tmp

Set DebugLevel=4 (i not understand what is level 5) in /etc/zabbix/zabbix_agentd.conf
and try start agent (as root) "/etc/init.d/zabbix-agent start" or direct "/usr/sbin/zabbix-agentd" and see your /tmp/zabbix_agentd.log
