<%- if @topic_view.topic.tags.present? %>
<%= t 'js.tagging.tags' %>: <%- @topic_view.topic.tags.each do |t| %> <%= t %> <%- end %>

i’m trying to set up email alert when my switches reach high chassis temp.
but i dont recieve any email, even if the temp treshold is reachead.

and here is the result of validate.php:

thanks for help!

I run two temperature alert rules: one for devices which have a high temperature alert limit, and a second for those which also have a (lower) high temperature warning limit:

sensors.sensor_current > sensors.sensor_limit AND sensors.sensor_class = "temperature"


sensors.sensor_current > sensors.sensor_limit_warn AND sensors.sensor_current <= sensors.sensor_limit AND sensors.sensor_class = "temperature"

The first applies globally, the second only to devices in a group defined by:

sensors.sensor_limit_warn != "NULL"


i will try this.
thanks for your help
