If your Unified Dashboard is not populating with data, make sure all required data sources for the Unified Dashboard are enabled. The required probe must be deployed and must be configured so that required QoS metrics and subkeys or targets are activated. For more information, see the help topic on required data sources for the Unified Dashboard.
EMC VMAX Required Data Sources
This table lists the probes, QoS metrics, and subkeys or targets that must be activated to populate data in the EMC VMAX dashboard.

System IO Performance
Column
Description
Host
Name of the system that hosts the VMAX server. Click the name of a host to view a Performance Report with IO performance data for that host. Enter text in the filter field in the column header to see only host names that contain that text.
Write/Sec
Number of write requests per second for the array.
Read/Sec
Number of read requests per second for the array.
Dir I/O per Sec
Number of IO requests per second for all directors.
Write Hit ratio
Aggregated ratio of write requests for the array found in cache, as opposed to disk. The higher this number, the better the performance.
Read Hit Ratio
Aggregated ratio of read requests for the array found in cache, as opposed to disk. The higher this number, the better the performance.
System Health
Column
Description
Host
Name of the system that hosts the VMAX server. Click the name of a host to view a Performance Report with data for that host. Enter text in the filter field in the column header to see only host names that contain that text.
Cache Size
Total cache size.
Cache Hit Ratio
Aggregated ratio of read and write requests for the array found in cache, as opposed to disk. The higher this number, the better the performance.
70 to 100 = Green
20 to 70 = Yellow
10 to 20 = Orange
0 to 10 = Red
Raw Disk Free Capacity
Total capacity of all disks.
50 to 100 = Green
30 to 50 = Yellow
5 to 30 = Orange
0 to 5 = Red
Device Pool Subscribed
Percent of total disk capacity that is subscribed.
0 to 50 = Green
50.01 to 75 = Yellow
75.01 to 90 = Orange
Greater than 90 = Red
System Data Throughput
Column
Description
Host
Name of the system that hosts the VMAX server. Click the name of a host to view a Performance Report with throughput data for that host. Enter text in the filter field in the column header to see only host names that contain that text.
Disk KB Read/Sec
Read rate for all disks in kilobytes per second.
Disk KB Write/Sec
Write rate for all disks in kilobytes per second.
Device KB Read/Sec
Read rate for all logical devices in kilobytes per second.
Device KB Write/Sec
Write rate for all logical devices in kilobytes per second.
Front-End Directors Status
Column
Description
Front-End Directors
Name of the director.
Op Status
Status of the director.
Online = Green
Other = Red
Read IO per sec
Read rate per second for the director.
