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

The one which sten has posted.

Are you trying to run this query in SWQL Studio?

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

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

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.
