Hello thanks for coming back, as was unable to setup SMTP easily I have moved that functionality to Grafana, and querying from influx.
Having a few teething problems including certain queries - created a new post here https://community.influxdata.com/t/flux-query-help/17831/2
There is the added issue of silence alerts which does not seem an option for a time frame within Grafana, as when patching occurs I would need to silence alerts from certain servers etc for certain days / hours a month
I am getting there and starting to understand the way Influx works and its integrations but still a very long way to go.
