problem logs

[Pablo]

I have created a host called betazabbix (server and agent are installs and running correctly).

I have creted a new item to read de /var/log/syslog.

Key: log[/var/log/syslog]
type:zabbix agent
Type of information:log
And I get de following error:
This is the zabbix_server.log:

Parameter [log[/var/log/syslog]] is not supported by agent on host [betazabbix] Old status [0]

This is my zabbix_agentd (it's installed on the server)

Server=127.0.0.1

# Server port for sending active checks

ServerPort=10051

# Unique hostname. Required for active checks.

Hostname=betazabbix

# Listen port. Default is 10050
