LAB16 alternative B error

AlexeyBY

Hello,
I cannot see any alerts http://myip:9090/alerts
Alertmanager don't show any alerts too but I can open with my browser HTTP GUI.

Pls download all files to the RESOURCE for this lab :
1.Final version of the alertmanager.yml;
2.Prometheus.yml;
3.alerting_rules.yml -> !!!! i think i've got worng here due to copy_past form the lab guide.
4. I don't perform the Lab 16.5 because 16.1-4 failed

thank you
