    That is used by the warehouse for all maintenance jobs… including aggregation.  

    To reduce the impact by that job… you can focus on:

    1.  Increasing the disk I/O and server resources for the data warehouse database.

    2.  Reduce the amount of data going into the warehouse, and reduce the retention.

    You really need to find out exactly what is causing the blocking when this runs… to determine the best course of action.  A SQL DBA with SQL profiler in hand should be able to indentify the major causes…

    How big is your warehouse?  Agent count?

    Kevin –

    I am experiencing the problems you describe for the CollectEventData workflows. If I follow your workaround, will I be prevent specific types of event collection? Can you provide more detail in what is causing this?



  3. Kevin Holman says:

    The IIS MP has some frequent and noisy discoveries.  Many run every hour.  I like to modify the frequency of those to once per day.

  4. Kevin Holman says:

    That is from the Exchange 2007 conversion MP – unfortunately – the event is created from script – if you turn off that workflow – you will also turn off the script.  đŸ™

    This is not a problem in the new native MP coming out with R2.  That event will be a top consumer – but should not flood the database – it just will be at the top of the list.

  5. Noah Deah says:

    I had the same symptoms (and pretty much all of them) as discussed above.  My problem seemed to be that I had inserted an account into the ‘Data Warehouse SQL Server Authentication Account’ ‘Run As Account’ where I should have had a space…. as noted here:


    This stopped the 2115 errors immediately.

  6. Kevin Holman says:

    No – we will simply drop batches of events that get stuck and hold up the queue.

  7. Kevin Holman says:

    So – that hotfix – 969130 – simply allows dropping of old event tables.  Their existence will not really impact event insertion into the DW – so that is why that didnt work.  Also – that could only possibly affect the DW.CollectEventData 2115, and no others.

    The MEP table query – dealed with discovery data.  This can be a problem when management packs run discoveries that constantly update discovery data with properties that change frequently.  If your only 2115 is from DW.CollectDiscoveryData – then a deeper analysis of discovered properties is in order.

    The best queries I have seen for that are here:


  8. Kevin Holman says:

    You should not make any overrides for this.

    The overrides in this article handled a very specific issue with events, and it is NOT applicable to perf collection.

    If you continuously have issues with perf insertion into the data warehouse – your warehouse is likely not performing well.  Look for blocking, and for avg disk sec/write values.

  9. Kevin Holman says:

    @Seth – I have heard about this… scalability issues with Unix monitoring.  Some good rules of thumb:

    1.  Dedicate the management server for cross platform monitoring and do not assign Windows agents to it.

    2.  Place the Management server health service queue on very fast disk with large IOPS capability and very low latency (RAID10 with 4 spindles, 15k drives, Tier 1 SAN, etc..)

    3.  Use physical hardware for the MS when scaling at maximum, with more than the minimum hardware requirements available for memory, CPU, etc…

    4.  Be very careful with what you write as far as custom workflows against the cross platform systems, as these can add additional load and will affect scale.

    My understanding is that we can scale up to 500 cross platform agents per MS when these are met above…. and using the built in MP's for base level Xplat monitoring.  

  10. Kevin Holman says:

    That override was not a fix to address all 2115’s.  It was only to address a specific situation with 2115 events of a Workflow Id : Microsoft.SystemCenter.DataWarehouse.CollectEventData.

    1.  Are ALL (at least 99%) your 2115 events coming from the above workflow?  If they are – then apply this override – and bounce the healthservice on your affected management server (in a cluster – take offline and then back online)  and you might consider clearing out the old healthservice cache.

    2.  If they are NOT all from DataWarehouse.CollectEventData, and are from random sources…. the next step is to see if they are all from a DataWarehouse workflow ID, or some are, some not.  In either case, this is typically SQL database performance related.  Bounce the healthservice and see if these comes back immediately, or if they take some time before you see them.

  11. Kevin Holman says:

    So – here is what I look at with 2115’s.

    1.  Look for a pattern – do the 2115’s happen at a specific time or random?  If a pattern – look for other jobs that might be running at that time, like a backup – or SQL DBA maintenance plans.

    2.  Look at the 2115’s… do they come from a single datasource/workflow… or multiple?  The workaround I posted only applies if they are ALL from the collectevent and data warehouse workflow.

    3.  Random 2115’s with LOW times… (under 300 seconds) are normal… as long as we recover.  If they have longer times associated with them… that is indicative of a SQL perf issue, or blocking on the DB.  SQL perf is caused by keeping too much data in the DB, bad disk/memory I/O, not enough spindles for the DB, DB and logs not being in distinct volumes/spindle sets, poor SAN performance, too many agents in the management group, other jobs stepping on the DB, too many consoles open, etc….

    Any help will be appreciated.


  13. mkielman says:

    One other question. Can this problem cause agents to receive the event "Alert generated by Send Queue % Used Threshold"?

  14. Kevin Holman says:

    You are correct – I did.  This was a copy/paste from a newsgroup posting.

  15. Kevin Holman says:

    I believe so – if the management server queue is also blocked.  One customer I worked with had a lot of send queue % alerts…. and these cleared up when we implemented this change.

  16. mkielman says:

    Thank you! It appears this fix has cleared up my issue as well including the Send Queue Alerts. Thanks!

  17. Kevin Holman says:

    When did you put in these overrides?

    If this just started – and the overrides have been in place for some time…. and SQL I/O performance is good… and this is ONLY coming from the warehouse collect event data source – then I would look for:

    1.  Blocking on the SQL server processes – check Activity monitor…. if performance counters look good on SQL – we can still have an insert problem if something is causing blocking.

    2.  Something is flooding events.  Run the most common event query from my SQL query blog – and see if you can determine the source.

  18. Rich says:

    I think you missed  


    from your workflows.

  19. sb says:

    i have applied all the 3 overrides :

    – Max Execution Attempt Count to 10

    – Execution Attempt Timeout Interval Seconds to 6

    – Max Batches To Process Before Maintenance Count to 50

    but 2115 warning on my RMS server are still arriving.  note that i have 2 physical rms and a virtual rms server (cluster)


  20. thomas says:

    Thx Kevin for this great Blob.

    I have been experiencing this error for a week now. After about 12 hours of working fine, the warnings 2115 start appearing. After some minutes, there are only 2115 errors in the Log and the RMS turns gray. The Workflow IDs include all possibilities, they seem to appear in a cyclic behavior to each other. The workaround didn’t fix it, unfortunatelly. I suspect a SQL performance problem. Before migrating the whole system to a new, better server, I just wanted to make sure if this might be the Problem.

  21. Mike Ory says:

    I just started getting these every 5 – 10 minutes.

    All coming from Microsoft.SystemCenter.DataWarehouse.CollectEventData

    They come back right away after bouncing the service. No MP’s have been added/deleted in about 3 months.

    The performance of the SQL server looks great The db and logs are on different volumes.

    I’ve set the 3 overrides as described above. I’ve rebooted my SQL server and then the RMS.

    Any other ideas?

  22. Mike Ory says:

    Thanks Kevin.

    Yes the overrides have been in place for a long time actually. I’m not seeing any blocking, but using your queries I found that a ton of events from our Exchange servers may be the problem.

    I’m going to disable the event collection rule: "Execute: Test-ServiceHealth diagnostic cmdlet", which seems to be one of the major contributors, and see what happens.

    And by the way, you say that you are not an expert on this subject? I have to repectfully disagree.  đŸ˜‰

  23. Mike Ory says:

    Turns out we DO have blocking.

    This is causing the issue, but I’m not sure what can be done about it:

    exec StandardDatasetMaintenance

  24. Dennis says:


    In our environment we have the same problem but nearly all 2115 errors are coming from the workflow Microsoft.SystemCenter.DataWarehouse.CollectPerformanceData with times ranging from 1 minute till 5 minutes before the cache is written to the DW. I tried making overrides to the Performance Data Collector analog to the Event Data Collector although the values aren’t exactly the same.

    I’ve put these settings for now:

    Maximum number of data items batches to process before maintenance: 50

    Subsequent execution attempt timeout interval in seconds: 6

    Maximum write operation execution attempt count: 10

    This still generates a lot of 2115 errors together with constant alert of the type: Performance data collection process unable to write data to the Data Warehouse which get closed the next minutes.

    Anything you can recommend?

  25. Mike Ory says:

    I’ve got a case open with Microsoft on this. I can tell you that one of the things they had me do (which didn’t work for me, but may work for you) is to install this hotfix:


    They also had me run this query, which I think tells me where most of my DW writes are coming from?

    select top 20 met.ManagedEntityTypeSystemName, count(*) from

    ManagedEntityProperty mep

       join ManagedEntity me on (mep.ManagedEntityRowId = me.ManagedEntityRowId)

       join ManagedEntityType met on (me.ManagedEntityTypeRowId =

    met.ManagedEntityTypeRowId) Where mep.FromDateTime > ‘2009-01-01’

    group by met.ManagedEntityTypeSystemName having (count(*)) > 5 order by 2 desc

  26. Mike Ory says:

    Ok, that’s good stuff. I ran the ‘Discovered Objects in the last 4 hours’ query and found that Microsoft.Windows.InternetInformationServices.2003.FTPSite has 36 changes.

    I can tell you for sure that we have not added any FTP Sites in quite awhile…

  27. augusto says:

    Great blog.

    Just wondering where I can find the ‘Discovered Objects in the last 4 hours’ query.


  28. John says:

    A Bind Data Source in Management Group ABC has posted items to the workflow, but has not received a response in 122 seconds.  This indicates a performance or functional problem with the workflow.

    Workflow Id : Microsoft.SystemCenter.DataWarehouse.CollectEntityHealthStateChange

    Instance    : MS4.ABC.local

    Instance Id : {43BE45BE-573D-AD34-B4333-3673F673BE32}

    This come 4 times within a couple of minuts (first 61 sec, 122, 183 and then 245) – but do also come 20 times in a hour – do have a cluster DB with 64 GB RAM and a cluster RMS with 16 GB and 6 MS with 8 GB. There are (for now) 32 agents connected to one MS and even I move agents to other MS then the events come on the "new" MS. It shouldn´t be performance issue – Any idea?

  29. mrbsmallz says:

    Worked like a charm for our OpsMgrR2 on VMWARE virtualized environment that is supporting 250 agents!  Thank you.

  30. Seth Technet says:

    I just battled this issue on the phone with MSFT for hours… turns out our 181 UNIX servers reporting to a single SCOM MS was causing this.  The UNIX boxes have been reporting to this SCOM MS for 2-3 months so the MSFT Performance team is going to contact me tomorrow to run some tests…. apparently UNIX is a disk I/O hog.  1 UNIX servers = 10 Windows servers on disk I/O.

  31. Paul Stonehewer says:

    Hi Kevin, I had ID2115 every 60 seconds covering all the Microsoft.SystemCenter.xxxxxx workflows. I looked at your fix and applied it, this just stopped me getting the errors it did not fix my problem which the RMS server (the only MS in the group) showing greyed out.

    I reviewed all the changes over the last couple of days since the problem occured and noticed that the Management Server Action account that had been in the Default Action Account Profile under the RMS server was now changed to local system.

    I changed this back and all my errors stopped reporting and the servers health was ok. Lessoned learnt….

    Keep up the good work


  32. Prabhu V says:

    Hi Kevin,

    Not really strange or if i am missing something here.

    In my env i have been having a lot of 2115 errors and many of them for “CollectPublishedEntityState” and “CollectAlertss” data.

    Upon looking for some blogs and the relevant workflow ids the majority is with "Workflow id: Microsoft.SystemCenter.CollectDiscoveryData", though i do find some for "Workflow id: Microsoft.SystemCenter.DataWarehouse.CollectEventData "

    I havent been able to crack for the first workflow id. Any help on this please?

  33. shiva says:

    Hi Kevin,

    I need your help in this issue. We are litterally getting alert ” Management server reached the quota limit” and also unable to discover any TFS build servers. I would request you to help me on this if you have created any blogs for this.

  34. Daya Ram says:

    I am getting 2115 events from Workflow Id : Microsoft.SystemCenter.DataWarehouse.CollectEntityHealthStateChange only and are generated about every hour. Datawarehouse SQL performance is also good. Please suggest how to troubleshoot these.

  35. Kevin Holman says:

    @Daya – if that is the only one you are receiving – that’s odd, and usually there will be other events that help us understand whats wrong. I’d recommend opening a support case IF these are values that are incrementing. If the times stay low (less than
    5 minutes) you might just be overloaded in the warehouse during aggregations, and you just need to do some tuning or get better disk IO

    Hi Kevin,
    I’m seeing following events in MS server every minute. My SCOM server is not healthy now. How to proceed on this?

    1. Kevin Holman says:

      @ Sebastian – that isnt a typical bind – that is NOTHING is writing to your DB.

      You need to investigate other events – it is likely access denied due to an account failure.

  37. This is a fantastic post! very informative!
    Although I am still in a little bit of a problem myself with this one, even after reading your great post here. I’m wondering if maybe you could help me out.
    See in my case I don’t have the Microsoft.SystemCenter.DataWarehouse.CollectEventData issue that you have, so your fix doesn’t work for me.
    So, I took your advice and I started analyzing the workflows, pending times and frequency of these events on all of my management servers:
    My top 5 offenders are the following with their respective event 2115 counts.
    Count – WorkflowId
    5932 – Microsoft.SystemCenter.CollectPerformanceData
    5931 – Microsoft.SystemCenter.CollectDiscoveryData
    5930 – Microsoft.SystemCenter.CollectSignatureData
    3247 – Microsoft.SystemCenter.CollectPublishedEntityState
    2497 – Microsoft.SystemCenter.CollectAlerts
    My grand total of events is 26375 across all my management servers and only 351 of these events are at or under the 120-second mark.
    The rest of the events hike all the way up to 15,540~1,041,840 seconds.
    Any ideas on what I should do with my situation here?

    1. Kevin Holman says:

      Those all point to the OpsDB.

      Either something is terribly wrong with your OpsDB performance, or you have significant blocking, or you have a permission issue and your SDK account is unable to write to the DB.

  38. Joff Andrada says:

    Hi Kevin,

    Quick question,

    We have redeploy our Datawarehouse database and now we are seeing lots of this warnings every minute:

    “A Bind Data Source in Management Group XXXXX has posted items to the workflow, but has not received a response in 420960 seconds. This indicates a performance or functional problem with the workflow.
    Workflow Id : Microsoft.SystemCenter.DataWarehouse.CollectPerformanceData
    Instance Id : {AF7BC122-3A06-C23F-4EE9-159AB43A0E47}”

    I’m also not seeing any data being written to the tables.

    Any idea on how can i resolve this issue?

    Your assistance will be greatly appreciated.
