Parameter | Dimension | Dimension Description | Format |
Instances.N.Dimensions.0.Name | target | Target dimension name | Enter a String-type dimension name: target |
Instances.N.Dimensions.0.Value | target | Subject to the query dimension | Please see the value reference table |
Note:
Valid values of
Instances.N.Dimensions.0.Value for TencentDB:
TencentDB for MongoDB is a cluster service. You can query monitoring data in three dimensions: "cluster", "replica set", and "node" as detailed below:"Cluster" dimension: it represents a certain TencentDB for MongoDB instance you purchased. In this dimension, you can query the number of read and write requests, capacity utilization, and timed-out requests of the entire instance.
"Replica set" dimension: you can query the internal capacity utilization and primary-secondary lag of a certain replica set in the cluster. A replica set instance itself contains only one replica set, while each shard of a shard instance is a replica.
"Node" dimension: you can query the CPU, memory, and other information of any node in the cluster.
dimensions.0.value value reference table
Value Type | Sample Value | Description |
Instance ID | cmgo-6ielucen | Unique ID of a TencentDB for MongoDB instance： which can be obtained in the TencentDB for MongoDB console or by calling an applicable TencentDB for MongoDB API |
Replica set ID | cmgo-6ielucen_0 cmgo-6ielucen_2 | A replica set ID can be obtained by adding "_index number" after the instance ID. The "index number" starts at 0 and can be up to the number of replica sets - 1. A replica set instance has only one replica set, so it is sufficient to always suffix "_0". A sharded instance has many shards, each of which is a replica set; for example, for the replica set ID of the third shard, suffix "_2" |
Node ID | cmgo-6ielucen_0-node-primary cmgo-6ielucen_1-node-slave0 cmgo-6ielucen_3-node-slave2 | Add "-node-primary" after the replica set ID to get the primary node ID of the replica set. Add "-node-slave node index number" after the replica set ID to get the corresponding secondary node ID. The "secondary node index number" starts at 0 and can be up to the number of secondary nodes - 1 |
Input Parameter Description
To query the monitoring data of a TencentDB for MongoDB instance, use the following input parameters:
&Namespace=QCE/CMONGO
&Instances.N.Dimensions.0.Name=target
&Instances.N.Dimensions.0.Value=subject to query dimension
Yes
No
