Measures reported by OraVdiDbTest
The Oracle VDI Core configuration data and runtime information is stored in a MySQL database, which may be shared across multiple Oracle VDI Core instances on the network. This database configuration ensures access to the Oracle VDI Core even in failover scenarios.
Since non-availability of the database can obstruct the normal functioning of the VDI core, it is imperative to periodically check the availability of the MySQL database.
This test runs availability checks on the MySQL database at configured intervals, and promptly alerts administrators whether the database is available or not. In a high availability configuration of the VDI core, you can use this test to also determine whether the database is the master or slave of a MySQL cluster.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement
Unit |
Interpretation |
| Status |
Indicates whether the database is currently available or not. |
|
If the database is available, then this measure will report the value Up. If the database is not available, then this measure will report the value Down.
The table below lists the numeric values that correspond to each of the states mentioned above:
| State |
Numeric Value |
| Up |
1 |
| Down |
0 |
Note:
Typically, this measure will report the States indicated in the table above as its values. However, in the graph of this measure, the status of the database will be represented using the numeric equivalents only - i.e., 0 and 1. |
| Database_host |
Indicates the percentage of memory utilized by the VDI manager service. |
|
The values that this measure reports and the numeric values that correspond to them are discussed in the table below:
The table below lists the numeric values that correspond to each of the states mentioned above:
| Measure Values |
Numeric Value |
| Master |
1 |
| Slave |
2 |
Note:
Typically, this measure will report the Measure Values indicated in the table above. However, in the graph of this measure, the status of the database will be represented using the numeric equivalents only - i.e., 1 and 2.
If the database is not part of a high availability cluster, then this measure will not be reported by the test.
