Steps to reproduce:

1. import and link the Supermicro template from here: https://github.com/v-zhuravlev/zbx_template_pack/tree/master/out/server/3.4
2. shutdown the Server
3. SNMP is still available but you will get a lot of alerts

Result:
See screenshot...

Expected:

• no non usefule alerts
• best would be a dependency if the server is up or down
