Solarwinds NPM and SAM performance issue

The last DB update time may be related more to a time difference between the SQL server and the Orion server. That itself does look a little odd since that's saying that nothing new has been written to database in 500 minutes. Definitely a problem and not at all related to not being able to keep up. If Orion was unable to keep up it would still be collecting and writing to the database, but likely things would not be polled as frequently as you would like or have configured. The result would be a marginal delay in how often things get polled, but the Orion server would still be polling *something* constantly, trying to keep up.

I would argue that you are probably right on the cusp of needing an Additional Poller, but I don't think that's related to your database update delay.You can determine how close you are to needing an additional poller by looking at [Settings - Polling Engines] and seeing what the following percentages look like. The closer you are to 100% (or over) the more likely you are to need an Additional Poller.

Also, I don't see the need for 10 vCPUs on the NPM/SAM server. The DB server definitely could do with a few more vCPUs - 1 is too little.  And, definitely, you will need to check the Polling Engines settings page to see where the polling throughput is at currently.

Hey Guys,

Thank you for response.  When i originally bought solarwinds it was just for a small group of servers, so i had the sql server running on the same box as the app.  As we added more i added more CPU, hence the reason for 10 vCPU's.  I'll be cutting that back one of these days.  I also added another vCPU to the SQL server to see if that helps any.  Below are my current polling rates.

Based on those numbers everything looks good. What does your polling completion rate look like on that same page?

Well came back from along weekend and my solarwinds servers was 1226 minutes behind!  Below is all the polling info.  I'm checking with my DBA team to see if they see any issues on the dba server.

I would recommend opening a case with support so we can dig through your log files to determine what's going on. Unfortunately this is a particularly difficult problem to troubleshoot properly via a forum like Thwack.
