Hi all.

I am not expert in db mssql but I trying checking the level of database fragmentation of CAUIM.

My db is Microsoft SQL Server 2014 (SP2-GDR) (KB4057120) - Standard Edition (64-bit).

When I execute this command

SELECT dbschemas.[name] as 'Schema',
dbtables.[name] as 'Table',
dbindexes.[name] as 'Index',
indexstats.avg_fragmentation_in_percent,
indexstats.page_count
FROM sys.dm_db_index_physical_stats (DB_ID(), NULL, NULL, NULL, NULL) AS indexstats
INNER JOIN sys.tables dbtables on dbtables.[object_id] = indexstats.[object_id]
INNER JOIN sys.schemas dbschemas on dbtables.[schema_id] = dbschemas.[schema_id]
INNER JOIN sys.indexes AS dbindexes ON dbindexes.[object_id] = indexstats.[object_id]
AND indexstats.index_id = dbindexes.index_id
WHERE indexstats.database_id = DB_ID()
ORDER BY indexstats.avg_fragmentation_in_percent desc

Return this tablas with fragmentation very high, according the documentation (UMP (USM) Slow Performance Guide and Troubleshooting Checklist 1.1) the tables fragmentation should be less than 30%.

I attached the file of all tables with fragmentation if your need see.

What can I do with this high fragmentation?

How does I reduce this fragmentation? because it feel certain slow when consulting data in the USM and maybe this is the problem.

M.E

So it would look like either the data_engine does not have the re-index enabled or it is failing for some reason.

the best thing to do is to engage your DBA.

have them setup a nightly job to re-index all of the tables in the database.

you both can review the UIM MS Sql best practice guide here:

CA UIM (Nimsoft) Database Best Practices for MS SQ - CA Knowledge 

Gene, the re-index not enable because I think understand that is only support MSSQL Enterprise and my CANIS is MSSQL2014 Standart.

That is fine. Then you will need to work with your DBA to setup a nightly schedule to re-index all tables in the UIM database using native database tools.

As a side note, High fragmentation and low page count is fine, high fragmentation and high page count is going to impact performance.

for reference:

How does data_engine maintenance and retention wor - CA Knowledge 

Yes ,It will cause slowness in UMP .Please do index rebuild in CA_UIM database and enable auto indexing in data_engine probe and ensure that it is working .
