6 Sender

Overview

�����IJ� sender is a command line utility that may be used to send performance data to �����IJ� server for processing.

The utility is usually used in long running user scripts for periodical sending of availability and performance data.

For sending results directly to �����IJ� server or proxy, a trapper item type must be configured.

Running �����IJ� sender

An example of running �����IJ� UNIX sender:

shell> cd bin
       shell> ./zabbix_sender -z zabbix -s "Linux DB3" -k db.connections -o 43

where:

• z - �����IJ� server host (IP address can be used as well)
• s - technical name of monitored host (as registered in �����IJ� frontend)
• k - item key
• o - value to send

�����IJ� sender can be used to send multiple values from an input file. See the �����IJ� sender manpage for more information.

�����IJ� sender accepts strings in UTF-8 encoding (for both UNIX-like systems and Windows) without byte order mark (BOM) first in the file.

�����IJ� sender on Windows can be run similarly:

zabbix_sender.exe [options]

Since �����IJ� 1.8.4, zabbix_sender realtime sending scenarios have been improved to gather multiple values passed to it in close succession and send them to the server in a single connection. A value that is not further apart from the 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, �����IJ� 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.
