Now I am able to get Network Down Alert for Single Node Separate Email for Each Node. Guide Me How to Get All the List of Down Nodes in Single Email.
This is where you need a down nodes report sending out in the email. So create your down nodes report and simply attach it to your email and send it out on a schedule say once a day.
You probably want to cut that list down a bit rather than just all. Draws false connections.An example similar macro is here:
Other downs in the last 15 minutes ${SQL: SELECT Caption+Char(9)+Char(10) FROM Nodes WHERE Vendor in ('Windows', 'Linux', 'net-snmp') AND Status like '2' AND ISServer like '1' AND DATEDIFF(minute, Nodes.LastSystemUpTimePollUTC, GETUTCDATE()) <= 15 AND Caption not like '${N=SwisEntity;M=Caption}' UNION SELECT ' ' AS Caption For XML path('') }</pre>
