Livecache data cache usage - table monitor_caches

Question

Hi Team,
We have a requirement of capturing the Data cache usage of Livecache on an hourly basis.
Instead of doing it manually by going into LC10 and copying the data into an excel, is there a table which captures this data on a periodic basis which we can use to get the report at a single shot.
"monitor_caches" is one table which holds this data, but we are not sure how we can get the data from this table. Also, we need to see the contents of this table, we are not sure how we can do that.
As "monitor_caches" is a maxdb table I am not sure how I can the data from this table. I have never worked on Maxdb before.
Has anyone had this requirement.
Warm Regards,
Venu

Hi,
For Cache usage below tables can be referred
Data Cache Usage - total (table MONITOR_CACHES)
Data Cache Usage - OMS Data (table MONITOR_CACHES)
Data Cache Usage - SQL Data (table MONITOR_CACHES)
Data Cache Usage - History/Undo (table MONITOR_CACHES)
Data Cache Usage - OMS History (table MONITOR_CACHES)
Data Cache Usage - OMS Rollback (table MONITOR_CACHES)
Out Of Memory Exceptions (table SYSDBA.MONITOR_OMS)
OMS Terminations (table SYSDBA.MONITOR_OMS)
Heap Usage (table OMS_HEAP_STATISTICS)
Heap Usage in KB (table OMS_HEAP_STATISTICS)
Maximum Heap Usage in KB (table ALLOCATORSTATISTICS)
System Heap in KB (table ALLOCATORSTATISTICS)
Parameter OMS_HEAP_LIMIT (KB) (dbmrfc command param_getvalue OMS_HEAP_LIMIT)
For reporting purpose , look into the following BW extractors and develop BW report.
/SAPAPO/BWEXDSRC APO -> BW: Data Source - Extractor
/SAPAPO/BWEXTRAC APO -> BW: Extractors for Transactional Data
/SAPAPO/BWEXTRFM APO -> BW: Formula to Calculate a Key Figure
/SAPAPO/BWEXTRIN APO -> BW: Dependent Extractors
/SAPAPO/BWEXTRMP APO -> BW: Mapping Extractor Structure Field
Hope this helps.
