Nodata in the [DiskRead and Write]&[Network Received and Transmitted] of the reports

Question

Hello everyone!
I'm a newbie.
The problem is the column of [DiskRead and Write]&[Network Received and Transmitted] has nodata.The others are OK(CPU,Memory etc.).  I already set the base rate for [DiskRead and Write]&[Network Received and Transmitted]  and I do some operations like copy files from one to another VM in the VM. But it still 0.00 in the report .
Can anybody tell me why? Is anything wrong in my vCenter Database?
Thank you very much!

Hello,
Thanks for sending the data.
The query that we asked you to run gives the values of network transmit-receive and disk read-write that CBM data collector has collected from VC.
A closer look at the output of the query shows that CBM has been able to collect data for network received and transmit (resource_id=6) from VC. The attached report contains costs for network received and transmit.
But there is no data for disk read and write (resource_id=2). So the report shows 0 costs for disk read and write.
Now we need to know the cause of  absence of this data from CBM DB. As a first step, we will like to see if VC DB contains disk read-write related data. Can you please attach the output of following steps?
1)  Please run following query on CBM DB
select entity_moid from cb_vc_entity where vc_entity_id=(select vc_entity_id from cb_vc_entity_mapping where cb_entity_id=(select entity_id from cb_entity where entity_name='work_GJL'))
This will give 'moid'. This moid should be used in the next query.
2) Please run following queries on VC DB.
We need outputs from 4 tables namely:
i) VPXV_HIST_STAT_YEARLY
ii) VPXV_HIST_STAT_MONTHLY
iii) VPXV_HIST_STAT_WEEKLY
iv) VPXV_HIST_STAT_DAILY
Substitute <table name> in the following query with each one of these and store the outputs of different queries independently and attach here.
select SAMPLE_TIME, SAMPLE_INTERVAL, STAT_VALUE from <table name> where ENTITY LIKE 'moid from above query' AND STAT_NAME = 'usage' and STAT_GROUP = 'disk' and STAT_ROLLUP_TYPE = 'average' order by SAMPLE_TIME
Thanks,
