Hi, can someone please clarify what does the ‘No Data’ rule state do or mean? Does it trigger an alert instantly (ignoring the rule’s For value)? Does it annotate the graph?
I want to get an alert, say 10 minutes after, a source server stops reporting (i.e. machine down or network timeout etc.), but I’m unsure if setting If no data or all values are null to No Data is the ideal solution, or having a separate rule condition with Has No Value?
