Sample alert is maybe too trigger happy

[micah]

The sample alertmanager alerts you provide are very helpul!

Unfortunately, if some temporary error condition happens, such as:

2021/10/15 20:27:48 while resolving for example.net.: dial tcp 1.1.1.1:53: connect: no route to host

then it will fire fairly quickly. I dont know if the alert should be tweaked to not be 1m or if the exporter should react differently in that scenario.
