multiple alerts are sended (up to 90 in my setup) each single time the monitoring service detects a missing service. All alerts have the exact same timestemp.
##### STEPS TO REPRODUCE
<!--
For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
- create a VPC / shared network with out providing service userdata / dns / dhcp
- wait for the first iteration of monitoring service
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
- if the monitoring service detects a missing service / service failure one alert should be sendet to the management server
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
- sending huge numbers of alerts to the management-server, which are related all to the timestemp and check of the monitoring service.
- Flooding of Alert-Overview with the same alert
~~~

@Hudratronium I've now a redundant VPC running with the same services but no alerts. The only difference is that I am running the latest, i.e. 4.16.0. If you have a change to reproduce it in a test environment, please try 4.16. I'll try out a 4.15.2 as well to see if I get any health check failures.

@Hudratronium can you give some clues as to which services are provided in the VPC and what the alerts are about.
I created a vpc without dns/dhcp/userdata and am trying to reproduce, but to no avail so far.

Hi @DaanHoogland
i enabled the healthchecks on my 4.16 environment. Up till now no "false" alerts or anything.
Result for dhcp check: "All 0 VMs are present ind dhcphosts.txt" <- Which seems logial to me as the dhcp service is not deployed. :-D Same result for the dns check.
So up till now this seems working for me under 4.16. Lovely!

Service Offerings of the VPC:
- Static NAT
- Portforwarding
- VPN
- NetworkACL
- SouceNAT
Checks that failed (that's why i disabled them manually):
- dhcp check
- dns check
If i remember correctly, this was the case for both routers - as i deployed a redundant VPC.
