How communication happen between zabbix GUI and Zabbix server?

[rangeshgupta]

Hi,

I m just exploring the architecture of the zabbix. There some point that i don't understands how it works.

1. How the communication between zabbix server and zabbix GUI is happening? Is it completely through database or you guys are using other methods also?

2. As to my understanding zabbix server puts all the latest values in cache. How that cache value is retried by the zabbix GUI?


Thanks

Regarding point 1: Yes, all communication between server and front end is going through the database.

For point 2, I doubt that the server can put data in any other cache than the database servers cache, but that sounds unlikely. The database usually handles this by itself. Maybe you are thinking of the server caching the list of hosts and items to get from the clients?

Thanks for your quick and valuable reply.

Sorry if my question was not clear.

Yea i m asking about the server caching.

Another thing, in the configuration file it is asking for

• Shared memory size for storing hosts and items data.
• Shared memory size for storing hosts and items data.
• Shared memory size for storing hosts and items data.
• Shared memory size for storing character, text or log history data.

Ques 1: So, for storing the data on shared memory he is reading from database or it has been kept at the time of polling?

Ques 2: At the time of polling, where the server put the latest value, database or server cache or both?


Thanks
