# 6 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 -s "Linux DB3" -k db.connections -o 43

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:

    # zabbix_sender -z 127.0.0.1 -i /tmp/traptest.txt 
    Info from server: "Processed 250 Failed 0 Total 250 Seconds spent 0.002668"
    Info from server: "Processed 50 Failed 0 Total 50 Seconds spent 0.000540"
    sent: 300; skipped: 0; total: 300

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.

::: noteclassic
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.
