    Minimize bandwidth usage on agent/server communication

    Hey,

    We are testing zabbix agent on devices which use mainly mobile connections with restricted data plans. We are using PSK for encryption.

    Currently I'm using the basic linux system template with 31 active items, cpu/process info etc. Using 1m interval on every item and 15 minute send buffer this translates to approx 465 data entries per communication (using 5m interval means 93 data entries and so on).

    I did some testing with these, removed all text types and it would seem that sending only integer/float items (with PSK) takes up about 135 bytes/item. That seems like way excessive for integer/float items. I wonder if there is something I could do about this? The length of PSK doesn't seem to matter much.

Working...
