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:
Starting with Zabbix 1.8.2, objects with whitespaces can be passed using zabbix_sender. In this case, these objects must be quoted using double quotes.
Starting with Zabbix 1.8.4, zabbix_sender has been improved in realtime sending scenarios by gathering multiple values that are passed to it in close succession, and sending them to the server in single connection. Value that is not further apart from previous value than 0.2 seconds can be put in the same stack, but maximum pooling time still is 1 second.
If sending many values from an input file, Zabbix sender will batch them at 250 values in one go (all values will be processed), for example:
All entries from an input file are sent in a sequential order top-down.
If the target item has triggers referencing it, all timestamps in an input file must be in an increasing order, otherwise event calculation will not be correct.
Starting from version 1.8.6 Zabbix Sender will terminate if invalid (not following parameter=value notation) parameter entry is present in specified configuration file.
See Zabbix Sender manpage for more information.
