asyncio-zabbix-sender 0.2.1

Asyncio implementation of the Zabbix Sender protocol

Zabbix sender

Dependency free implementation of the Zabbix Sender protocol using asyncio.

Key features:

• Full specification implemented compared to other Zabbix sender implementations
• Compression is enabled as default
• Asynchronous implementation allows the program to continue while waiting for a response from Zabbix

Installation

The package can be found on PyPI and installed using pip:

pip install asyncio-zabbix-sender

Usage

The measurements for the Zabbix trapper item(s) can be sent using a high-level API. The Measurements object is a collection of measurements. The measurements can both be added via the constructor (as per the example below), but also dynamically via the add_measurement method.

import datetime
from asyncio_zabbix_sender import ZabbixSender, Measurements, Measurement

sender = ZabbixSender("example.com")

measurements = Measurements([
    Measurement(
        "vm-game-server", "cheat.used[doom,player1]", "idkfa", datetime.datetime.utcnow()
    )
])

response = await sender.send(measurements)

This package can also be used on a lower level to send packets directly.

from asyncio_zabbix_sender import create_packet, ZabbixSender

packet = create_packet(
    request=b'{"request":"sender data","data":[{"host":"<hostname>","key":"trap","value":"test value"}]}',
    use_compression=True
)

sender = ZabbixSender("example.com")
response = await sender.send_packet(packet)

Logging

The logger can be configured by using the name asyncio-zabbix-sender:

import logging

logger = logging.getLogger("asyncio-zabbix-sender")
logger.setLevel(logging.DEBUG)

Example from the test_send unit test by running pytest with --log-cli-level=DEBUG:

DEBUG    asyncio-zabbix-sender:_protocol.py:47 Compressed packet: 40 bytes. Original 35.
DEBUG    asyncio-zabbix-sender:_zabbix_sender.py:63 Created packet from measurements. Used compression: True.
DEBUG    asyncio-zabbix-sender:_zabbix_sender.py:78 Sending packet: b'ZBXD\x03(\x00\x00\x00#\x00\x00\x00x\x9c\xabVJI,IT\xb2\x8a\x8e\xd5Q*J-,M-.Q\xb2R*N\xcdKI-R\x00K\xd5\x02\x00\xd3\xc2\x0b\xfb'

Note that only a summary of the packet that are send and the response received are logged as informational. Everything else is logged at debug level.

The INFO log entry contains the response flags. A response flag are set by:

• 0x01 - Zabbix communications protocol
• 0x02 - If compression is used
• 0x04 - If the response is a large packet

Road map

The following improvements are planned (not necessary in order):

• Better error handling
• More documentation (how to set up ssl among other things)
