Node Down Time

You can use this query as an SWQL report or as a Query Widget. It is excellent as a widget as it includes hyperlinks. Credit to the original creator for adding all the comments!

Hi,

I am trying to use above sql query but its giving me an error as Invalid column name 'Nodes'. at StartTime.Nodes.NodeID

Please suggest

When I try to run his Query in SWQL Studio I get an error 

for your error... try changing 'Nodes.' to 'Node.'

have you tried my query above?

It didnt work, same error.

Before using i have removed any custom property, actually I am trying to convert this script as SQL one. As that the requirement.

In swql, verify your tables...

for the error posted above you must either comment or remove line 7 from the query. It is referencing a custom property that you likely do not have,

Yes I tried yours and its working, but failing to validate the out put of query to actual events on the nodes. I am finding that there is different in actual down event on the device when I see it from the console. Still validating 

Hi, I am getting error on line number 18 where its saying invalid column name node, custom property I have already removed

If you are trying to use SQL... try this...

SELECT * from (

SELECT

StartTime.EventTime AS DownEventTime,

(SELECT TOP 1

EventTime

FROM Events AS Endtime

WHERE EndTime.EventTime >= StartTime.EventTime

AND EndTime.EventType = 5

AND EndTime.NetObjectType = 'N'

AND EndTime.NetworkNode = StartTime.NetworkNode

AND EventTime IS NOT NULL

ORDER BY EndTime.EventTime) AS UpEventTime,

Nodes.Caption, StartTime.Message, DATEDIFF(Mi, StartTime.EventTime,(SELECT TOP 1 EventTime FROM Events AS Endtime

WHERE EndTime.EventTime > StartTime.EventTime AND EndTime.EventType = 5 AND EndTime.NetObjectType = 'N'

AND EndTime.NetworkNode = StartTime.NetworkNode  ORDER BY EndTime.EventTime)) AS OutageDurationInMinutes

FROM Events StartTime INNER JOIN Nodes ON StartTime.NetworkNode = Nodes.NodeID

WHERE (StartTime.EventType = 1)

) as uptimetable

WHERE outageDurationInMinutes IS NOT NULL
ORDER By DownEventTime DESC

If you are trying to use SQL... try this...

SELECT * from (

SELECT

StartTime.EventTime AS DownEventTime,

(SELECT TOP 1

EventTime

FROM Events AS Endtime

WHERE EndTime.EventTime >= StartTime.EventTime

AND EndTime.EventType = 5

AND EndTime.NetworkNode = StartTime.NetworkNode  ORDER BY EndTime.EventTime)) AS OutageDurationInMinutes

FROM Events StartTime INNER JOIN Nodes ON StartTime.NetworkNode = Nodes.NodeID

WHERE (StartTime.EventType = 1)

) as uptimetable

WHERE outageDurationInMinutes IS NOT NULL
ORDER By DownEventTime DESC

Thanks John its working,

But somehow its not taking all the down event against a device. Eg. there is a device for which I can see 3 down/up event in web console events tab for last month but SQL output shows  only first two down/up even pair.

I am not sure why this behavior, please suggest. 

Trying to modify it to group by Device and Order by Down Event in descending order but getting an error.
