Node Down Time

All,  I am looking for some SWQL/SQL code that can pull out the following information from the database. 

Columns Include: 

  • Device Name
  • IP Address
  • Time Down
  • Time Up 
  • Minutes Node was down

  • 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!

    select n.caption as [Device]
    -- shows the current status icon
    , '/Orion/images/StatusIcons/Small-' + n.StatusIcon AS [_IconFor_Device]
    -- makes a clickable link to the node details
    , n.DetailsUrl as [_linkfor_Device]
    --Show Mute Node Down Custom Property
    , n.customProperties.IgnoreNodeDown
    -- shows the timestamp of the down event, if there is no timestamp then is says the event was greater than the number of days in your event retention settings
    , isnull(tostring(t2.[Down Event]),concat('Greater than ',(SELECT CurrentValue FROM Orion.Settings where settingid='SWNetPerfMon-Settings-Retain Events'),' days ago')) as [Down Event]
    -- shows the timestamp of the up event, unless the object is still down
    , isnull(tostring(t2.[Up Event]),'Still Down') as [Up Event]
    -- figures out the minutes between the down and up events, if the object is still down it counts from the down event to now, displays 99999 if we cannot accurately determine the original downtime, and 
    , isnull(MINUTEDIFF(t2.[Down Event], isnull(t2.[Up Event],GETDATE())),99999) as Minutes

  • 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

  • If you would, please give us more details on what you are trying to do?  Maybe you can post your exact code??

  • Also, the above query is not for SQL.. it is for SWQL

  • Thanks John,

    I am using the above mentioned SWQL script to generate report. But its giving me an error Invalid column name 'Nodes'. at StartTime.Nodes.NodeID line in the script.

    Am I missing anything here?

  • there are actually two different scripts above...  which are you using? The one that I posted? or the one that sten posted?  can you post the exact script you are trying to use?

  • 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.'

  • 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.
