Description
Steps to reproduce:
- Install several Zabbix proxies (use active mode)
- Enable PSK based encryption for the proxies
- Don't add proxies in the frontend for now
- Wait for an hour
- Check incoming traffic on Zabbix server
Result:
Each proxy generates ~11 Mbps of traffic. I.e. 10 proxies will push ~110 Mbps. Imagine if you have 1000 of proxies... These not registered proxies may overload Zabbix server network interface easily.
Steps to reproduce:
- Add these new proxies in the frontend (Administration --> Proxies)
- Wait for a moment and check incoming traffic graph again. You will see that each proxy will use ~10Kbps now (proxy has no monitored hosts).
Expected:
Not registered proxy should generate less traffic or send configuration request not so frequently.
Notes:
- I didn't test passive proxies
- I didn't test proxies without encryption
