Murphy,
That looks like you are in the recorder. The query that I was running is directly against the database. Either through the Database manager tool on the core Solarwinds Server (provided by solarwinds) or in your database directly. Alternatively, you can go petr's route through the web interface and change the playback period on each location that the recording is playing from. Our institution has over 30 locations and more than 100 recordings at each, so it was cumbersome and time consuming to go through the UI.
If i'm taking a guess, (this is just a guess). You're SQL statement would look something like this (assuming the recording "Name" is HPNA)
Update [SolarWindsOrion].[dbo].[SEUM_Transactions]
SET [Frequency] = 600
Where [Name] Like 'HPNA%'
YOU CAN VERIFY AND CHECK BY RUNNING THE FOLLOWING (NO UPDATING)
SELECT TOP 1000 [TransactionId]
,[RecordingId]
,[AgentId]
,[Name]
,[Description]
,[Frequency]
,[Unmanaged]
,[UnmanageFrom]
,[UnmanageUntil]
,[JobId]
,[LastStatus]
,[LastDuration]
,[LastDateTimeUtc]
,[LastErrorMessage]
,[WarningThreshold]
,[CriticalThreshold]
,[LastModificationUtc]
FROM [SolarWindsOrion].[dbo].[SEUM_Transactions]
WHERE [Name] Like 'HPNA%'
Does this help?
