ZABBIX Processes
ZABBIX Server
ZABBIX Server is a central process of ZABBIX software. ZABBIX Server can be started by executing:
shell> cd bin shell> ./zabbix_server
ZABBIX Server runs as a daemon process.
ZABBIX Server accepts the following command line parameters:
-c --config <file> specify configuration file, default is /etc/zabbix/zabbix_server.conf -h --help give this help -v --version display version number
In order to get this help run:
shell> zabbix_server -h
Example of command line parameters:
shell> zabbix_server –c /usr/local/etc/zabbix_server.conf shell> zabbix_server --help shell> zabbix_server -v
The configuration file contains parameters for zabbix_server. The file must exist and it should have read permissions for user ‘zabbix’. Supported parameters:

ZABBIX Agent (UNIX, standalone daemon)
ZABBIX UNIX Agent runs on a host being monitored. The agent provides host's performance and availability information for ZABBIX Server.
ZABBIX Agent processes items of type ‘ZABBIX Agent’ or ‘ZABBIX Agent (active)’.
ZABBIX Agent can be started by executing:
shell> cd bin shell> ./zabbix_agentd
ZABBIX Agent runs as a daemon process.
ZABBIX Agent accepts the following command line parameters:
-c --config <file> specify configuration file, default is /etc/zabbix/zabbix_agentd.conf -h --help give this help -v --version display version number -p --print print supported metrics and exit -t --test <metric> test specified metric and exit
In order to get this help run:
shell> zabbix_agentd –h
Example of command line parameters:
shell> zabbix_agentd –c /usr/local/etc/zabbix_agentd.conf shell> zabbix_agentd –help shell> zabbix_agentd –print shell> zabbix_agentd –t “system.cpu.load[all,avg1]”
The configuration file contains configuration parameters for zabbix_agentd. The file must exist and it should have read permissions for user ‘zabbix’. Supported parameters:

ZABBIX Agent (Windows)
ZabbixW32 is ZABBIX agent for Win32 systems. It will work on Windows NT 4.0, Windows 2000, Windows XP, and Windows Vista.
Installation
Installation is very simple and includes 3 steps: Create configuration file. Step 1 Create configuration file c:/zabbix_agentd.conf (it has the same syntax as UNIX agent). Install agent as a Windows service. Step 2 ZabbixW32.exe install If you wish to use configuration file other that c:\zabbix_agentd.conf, you should use the following command for service installation: ZabbixW32.exe --config <your_configuration_file> install Full path to configuration file should be specified. Run agent. Step 2 Now you can use Control Panel to start agent's service or run: ZabbixW32.exe start Windows NT 4.0 note. ZabbixW32 uses PDH (Performance Data Helper) Note: API to gather various system information, so PDH.DLL is needed. This DLL is not supplied with Windows NT 4.0, so you need to download and install it by yourself. Microsoft Knowledge Base article number 284996 describes this in detail and contains a download link. You can find this article at http://support.microsoft.com/default.aspx?scid=kb;en-us;284996
Usage
zabbixw32 [options] [command] ZABBIX Windows Agent accepts the following command line parameters: check-config Check configuration file and exit. help Display help information. install Install ZABBIX Win32 Agent as a service. install-events Install ZABBIX Win32 Agent as event source for Event Log. This is done automatically when service is being installed. remove Remove previously installed ZABBIX Win32 Agent service. remove-events Remove ZABBIX Win32 Agent event source. This is done automatically when service is being removed. standalone Run in standalone mode. start Start ZABBIX Agent service. stop Stop ZABBIX Agent service. version Display version information. And possible options are: --config <file> Specify alternate configuration file (default is c:\zabbix_agentd.conf). The file contains configuration parameters for ZabbixW32. Supported parameters: Parameter Mandatory Default value Description No - Sets the alias for parameter. Alias It can be useful to substitute long and complex parameter name with a smaller and simpler one. For example, if you wish to retrieve paging file usage in percents from the server, you may use parameter
"perf_counter[\Paging
File(_Total)\% Usage]", or
you may define an alias by
adding the following line to
configuration file: Alias =
pg_usage:perf_counter[\Pagi
ng File(_Total)\% Usage]
After that you can use
parameter name "pg_usage"
to retrieve the same
information. You can specify
as many "Alias" records as
you wish. Please note that
aliases cannot be used for
parameters defined in
"PerfCounter" configuration
file records.
No - The parameter has no effect.

For example, if you wish to
receive average number of
processor interrupts per
second for last minute, you
can define new parameter
"interrupts" as following:
PerfCounter =
interrupts,"\Processor(0)\Inter
rupts/sec",60
Please note double quotes
around performance counter
path. Samples for calculating
average value will be taken
every second.
No - The parameter has no effect.

servers. Connections from
other IP addresses will be
rejected.
No - The parameter has no effect.

several user-defined
parameters. Value has form

not use spaces around pipe

ZABBIX Sender (UNIX)
ZABBIX UNIX Sender is a command line utility which may be used to send performance data to ZABBIX Server for processing.
The utility is usually used in long running user scripts for periodical sending of availability and performance data.
ZABBIX Sender can be started by executing:
shell> cd bin shell> ./zabbix_sender –z zabbix –p 10051 –h LinuxDB3 –k db.connections –o 43
ZABBIX Sender accepts the following command line parameters:
-z --zabbix-server <zabbix server> Hostname or IP address of ZABBIX Server. -p --port <zabbix server port> Specify port number of server trapper running on the server. Default is 10051. -s --host <host name or IP> Specify host name or IP address of a host. -k --key <key of metric> Specify metric name (key) we want to send. -o --value <value> Specify value of the key. -i --input-file <input file> Load values from input file. -h –help Give this help. -v –version Display version number.
In order to get this help run:
shell> zabbix_sender -h
ZABBIX Get (UNIX)
ZABBIX UNIX Get is a process which communicates with ZABBIX Agent and retrieves required information.
The utility is usually used for troubleshooting of ZABBIX Agents.
ZABBIX Get can be started by executing:
shell> cd bin shell> ./zabbix_get -s127.0.0.1 -p10050 -k"system.cpu.load[all,avg1]"
ZABBIX Get accepts the following command line parameters:
-p --port <port number> Specify port number of agent running on the host, Default is 10050 -s --host <host name or IP> Specify host name or IP address of a host. -k --key <key of metric> Specify metric name (key) we want to retrieve. -h --help Give this help. -v --version Display version number.
In order to get this help run:
shell> zabbix_get -h
