I've installed new NPM 20.20.6 and now the dust settled - I have completed adding several dozen nodes to monitor.
However, there are no 'pre-configured' alerts in the 'manage' alerts. I selected no groupings and nothing is showing.
I had to create 2 alerts. One to alert when node status is Down, other alert when node status is Up.
Did I miss a step when installing NPM 20.20.6? I did a web install and it was done in about 1 hour.
Thank you all for your input.
