# 6 Archive: Zabbix agent (UNIX, Inetd version)

The parameters supported in a Zabbix agent (UNIX, Inetd version)
configuration file:

|Parameter|Mandatory|Default value|Description|
|---------|---------|-------------|-----------|
|Alias|no|<|Sets an alias for an item key.<br>The alias can be used instead of the full item key in item configuration. For example:<br>*Alias*=system.cpu.load\[percpu,5\]:system.cpu.load\[percpu,avg5\]<br>*Item key*: system.cpu.load\[percpu,5\]<br>*Item name*: Processor load ($2 min average per core)<br>An alias can be especially useful to substitute a long and complex item key with a smaller and simpler one. Multiple aliases can be defined.|
|Include|no|<|You may include individual files or all files in a directory in the configuration file. See [special notes](special_notes_include) about limitations.|
|Server|yes|\-|Comma-delimited list of IP addresses of Zabbix servers or proxies. Connections from other IP addresses will be rejected.|
|Timeout|no|3|Do not spend more than Timeout seconds on getting requested value (1-255). The agent does not kill timeouted user parameter processes!|
|UnsafeUserParameters|no|0|Allow all characters to be passed in arguments to user-defined parameters|
|UserParameter|no|<|User-defined parameter to monitor. There can be several user-defined parameters.<br>Format: UserParameter=<key>,<shell command><br>Note that shell command must not return empty string or EOL only.<br>Example: UserParameter=system.test,who\|wc -l|
