Understanding Zabbix Protocols and Operations

[LunaLoomer]

Hello Zabbix Enthusiasts,

As I navigate my way through learning Zabbix, I've encountered some questions regarding the protocols it utilizes. I'd appreciate some clarity on the following:

What protocols does Zabbix use between the Zabbix server and agent? (I'm aware of TCP 10050 and 10051, but any additional insights would be helpful.)
Which protocol(s) does the Zabbix agent employ to gather data on the host?
Are there other protocols involved in various aspects of Zabbix operations that I should be aware of?
Additionally, I'm curious about Zabbix operations like trap and get. How do these compare to SNMP trap and SNMP get?

Your expertise in navigating Zabbix protocols will greatly assist my learning journey. Thank you in advance for sharing your insights!

Hi, note that currently Wireshark version 4.2.0 (and newer) is able to dissect Zabbix protocol as well, so go ahead and capture some traffic and see the protocol(s) in action.

Also see the Zabbix documentation about the protocols: https://www.zabbix.com/documentation...ndix/protocols

The network-level behavior of Zabbix agent (when gathering data) obviously depends on the items that are being used. Most item data is gathered using system-level APIs or similar calls (like the filesystem data or CPU/memory utilizations).

Thank you, Markku, for your insightful response. The tip about Wireshark version 4.2.0 is particularly helpful, and I'll make sure to explore capturing Zabbix traffic for a more hands-on understanding.

I've also taken a look at the Zabbix documentation you shared regarding protocols, and it's proving to be a valuable resource in my learning journey.

As I delve deeper, I'm curious if there are any community-recommended best practices or additional resources for understanding Zabbix protocols. Your experiences and guidance are immensely appreciated.

Looking forward to further discussions and insights!
