Today’s Frog-Blog top-tips are quite simple ones, but ones that I always find very useful. SSRS Report Performance monitoring.

Once you start to build up a few Reporting Services reports, you need to find out how they’re performing, whether any particular reports are causing the server problems and even which users are running which reports. The following set of queries should point you in the right direction. They should all be run against the ReportServer database.

The 20 most recently run reports

  SELECT TOP 20
     C.Path, C.Name,
     EL.UserName,
     EL.Status,
     EL.TimeStart,
     EL.[RowCount],
     EL.ByteCount,
     (EL.TimeDataRetrieval
          + EL.TimeProcessing
          + EL.TimeRendering)/1000 AS TotalSeconds,
     EL.TimeDataRetrieval,
     EL.TimeProcessing,
     EL.TimeRendering
  FROM ExecutionLog EL
     INNER JOIN Catalog C ON EL.ReportID = C.ItemID
  ORDER BY TimeStart DESC

The slowest reports (in the last 28 days)

  SELECT TOP 10
     C.Path, C.Name,
     Count(*) AS ReportsRun,
     AVG((EL.TimeDataRetrieval
        + EL.TimeProcessing
        + EL.TimeRendering)) AS AverageProcessingTime,
     Max((EL.TimeDataRetrieval
        + EL.TimeProcessing
        + EL.TimeRendering)) AS MaximumProcessingTime,
     Min((EL.TimeDataRetrieval
        + EL.TimeProcessing
        + EL.TimeRendering)) AS MinimumProcessingTime
  FROM ExecutionLog EL
     INNER JOIN Catalog C ON EL.ReportID = C.ItemID
  WHERE EL.TimeStart>Datediff(d,GetDate(),-28)
  GROUP BY C.Path,C.Name
  ORDER BY
     AVG((EL.TimeDataRetrieval
        + EL.TimeProcessing
        + EL.TimeRendering)) DESC

The most active users

  SELECT TOP 10
     EL.UserName,
     Count(*) AS ReportsRun,
     Count(DISTINCT [C.Path]) AS DistinctReportsRun
  FROM ExecutionLog EL
     INNER JOIN Catalog C ON EL.ReportID = C.ItemID
  WHERE EL.TimeStart>Datediff(d,GetDate(),-28)
  GROUP BY EL.UserName
  ORDER BY Count(*) DESC

The most popular reports

  SELECT TOP 10
     C.Path, C.Name,
     Count(*) AS ReportsRun,
     AVG((EL.TimeDataRetrieval
        + EL.TimeProcessing
        + EL.TimeRendering)) AS AverageProcessingTime,
     Max((EL.TimeDataRetrieval
        + EL.TimeProcessing
        + EL.TimeRendering)) AS MaximumProcessingTime,
     Min((EL.TimeDataRetrieval
        + EL.TimeProcessing
        + EL.TimeRendering)) AS MinimumProcessingTime
  FROM ExecutionLog EL
     INNER JOIN Catalog C ON EL.ReportID = C.ItemID
  WHERE EL.TimeStart>Datediff(d,GetDate(),-28)
  GROUP BY C.Path, C.Name
  ORDER BY Count(*) DESC

Failed Reports

  SELECT TOP 20
     C.Path, C.Name,
     EL.UserName,
     EL.Status,
     EL.TimeStart,
     EL.[RowCount],
     EL.ByteCount,
     (EL.TimeDataRetrieval
          + EL.TimeProcessing
          + EL.TimeRendering)/1000 AS TotalSeconds,
     EL.TimeDataRetrieval,
     EL.TimeProcessing,
     EL.TimeRendering
  FROM ExecutionLog EL
     INNER JOIN Catalog C ON EL.ReportID = C.ItemID
  WHERE EL.Status <> 'rsSuccess'
  ORDER BY TimeStart DESC

There are countless other variations, but this should be enough to get you going.
