dfm interface slow

I have added 4 new filers to my estate and ops manager has become very slow.  There are only 15 filers in total and the DFM database monitordb.db is now 370 Mb in size on a high spec, single task server with 4Gb of ram.  This server is only used for Ops and performance manager and both apps are running standard monitoring and are not killing the box poling every second, etc.

Any ideas why the interface just sticks at "loading"?  Please see image.

We have also move some volumes between aggregates by using snapmirror and rename.

Thanks

Re: dfm interface slow

Which version of DFM are you using?

Re: dfm interface slow

3.7 - Sorry should have put it in the post.

Re: dfm interface slow

Can you provide the NMC logs for further debugging ? If you are able to reproduce this issue, set the  log level as ALL (default is ERROR) in the log4j.properties in the NMC home directory and send them.

Re: dfm interface slow

Sorry I forgot about this issue but have started using DFM again and the problems are worse than ever.

The E:\Program Files\NetApp\DataFabric\DFM\data\monitordb.db is 395 Mb yet the dbsrv9.exe process only shows 353 Mb in windows task manager.

The windows service "DFM Sybase ASA" - DataFabric Manager database server starts the database with the switch below.

"E:\Program Files\NetApp\DataFabric\Sybase\ASA\win32\dbsrv9.exe" -hvDFMSybase

Has anyone played with the cache options to speed up the databse?

Re: dfm interface slow

Maybe you already checked it, but is a virusscanner perhaps active?

Running on linux here: 28 filers, 1.8 GB database and 125 GB of PA data. All running smooth.

Re: dfm interface slow

AV does not scan the database folder.

Thanks for the idea however.

Re: dfm interface slow

Going to deploy v4 of Operations manager.  Many changes to improve performance in this release.

Re: dfm interface slow

Just wndering how anyone got on with v4 of DFM and if it has improved performance.

was v4 installed on a Linux OS rather than windows.

Im having performance issues with W2K3 server running DFM v3.x monitoring approx 10 appliances, mostly it appears DB/SQL related.

Thanks.

Hi Martin,

Can you paste the output of 'dfm about' in the DFM version that you are currently using.

Looks like in current version, there is not enough free space in the installation directory.

A sample output :

[root@lnx186-143 script]# dfm about
CPU Count                        1
System Memory                    2026 MB (load excluding cached memory: 69%)
Installation Directory           /opt/NTAPdfm
                                 2.17 GB free (17.1%)
