Measures reported by MongoWorkloadTest
Periodically, administrators should measure the workload on the Mongo database server and evaluate the server's ability to handle the load, so that they can figure out whether the server's sized commensurate to its load or not. Administrators can perform this load analysis using the MongoWorkloadTest test.
This test tracks the load on the Mongo database server and reports what type of operations are contributing to the workload of the server. The test additionally reports the number of clients performing read and write operations on the server, so that you can figure out the count of clients that are generating the load on the MongoDB server. Capacity planning and clustering decisions can be taken based on insights provided by this test.
Outputs of the test : One set of results for the target Mongo database server being monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Insert_oper_rate |
Indicates the rate at which insert operations are performed on the target server. |
Inserts/Sec |
|
| Query_oper_rate |
Indicates the rate at which query operations are performed on the target server. |
Queries/Sec |
|
| Update_oper_rate |
Indicates the rate at which update operations are performed on the target server. |
Updates/Sec |
|
| Delete_oper_rate |
Indicates the rate at which delete operations are performed on the target server. |
Deletes/Sec |
|
| Getmore_rate |
Indicates the rate at which get more operations are performed on the target server. |
Getmores/Sec |
|
| Commands_rate |
Indicates the rate at which command operations are performed on the target server. |
Commands/Sec |
|
| Read_requests |
Indicates the rate at which read requests are received by the target server. |
Requests/Sec |
A consistent increase in the value of these measures could indicate a potential overload. |
| Write_requests |
Indicates the rate at which write requests are received by the target server. |
Requests/Sec |
| Read_operations |
Indicates the number of the active client connections performing read operations. |
Number |
The value of these measures indicate how many clients are generating the load on the MongoDB server. |
| Write_operations |
Indicates the number of the active client connections performing write operations. |
