Tencent Cloud Redis¶

Tencent Cloud Redis Metrics display, including connections, requests, latency, slow queries, etc.

Configuration¶

Install Func¶

It is recommended to enable TrueWatch Integration - Extensions - DataFlux Func (Automata): All prerequisites are automatically installed, please proceed with script installation.

If deploying Func manually, refer to Manual Func Deployment

Install Script¶

Note: Please prepare Tencent Cloud AK with the required permissions in advance (for simplicity, you can directly grant global read-only permissions ReadOnlyAccess).

To synchronize Tencent Cloud-Redis monitoring data, we install the corresponding collection script: "TrueWatch Integration (Tencent Cloud-Redis Collection)" (ID: integration_tencentcloud_redis).

Click 【Install】, then input the corresponding parameters: Tencent Cloud AK, Tencent Cloud account name.

Click 【Deploy Startup Script】, the system will automatically create a Startup script set and configure the corresponding startup scripts.

Additionally, in 「Manage / Auto Trigger Configuration」, you can see the corresponding auto-trigger configuration. Click 【Execute】 to immediately execute once without waiting for the scheduled time. Wait a moment, and you can view the execution task records and corresponding logs.

We have collected some configurations by default, for details see the Metrics section Configure Custom Cloud Object Metrics

Verification¶

1. In 「Manage / Auto Trigger Configuration」, confirm whether the corresponding task exists in the auto-trigger configuration, and check the task records and logs for any exceptions.
2. In TrueWatch, check if asset information exists in 「Infrastructure / Custom」.
3. In TrueWatch, check if there is corresponding monitoring data in 「Metrics」.

Metrics¶

After configuring Tencent Cloud-Redis, the default Measurement is as follows. More Metrics can be collected through configuration Tencent Cloud Monitoring Metrics Details

Redis Instance Monitoring¶

Overview of Parameters for Each Dimension¶

Input Parameter Description¶

To query Tencent Cloud Redis instance monitoring data, input parameters are as follows: &Namespace=QCE/REDIS_MEM &Instances.N.Dimensions.0.Name=instanceid &Instances.N.Dimensions.0.Value=Instance ID

To query Tencent Cloud Proxy node monitoring data, input parameters are as follows: &Namespace=QCE/REDIS_MEM &Instances.N.Dimensions.0.Name=instanceid &Instances.N.Dimensions.0.Value=Instance ID &Instances.N.Dimensions.1.Name=pnodeid &Instances.N.Dimensions.1.Value=Proxy Node ID

To query Tencent Cloud Redis node monitoring data, input parameters are as follows: &Namespace=QCE/REDIS_MEM &Instances.N.Dimensions.0.Name=instanceid &Instances.N.Dimensions.0.Value=Instance ID &Instances.N.Dimensions.1.Name=rnodeid &Instances.N.Dimensions.1.Value=Redis Node ID

To query Tencent Cloud Redis latency metrics (command dimension) monitoring data, input parameters are as follows: &Namespace=QCE/REDIS_MEM &Instances.N.Dimensions.0.Name=instanceid &Instances.N.Dimensions.0.Value=Instance ID &Instances.N.Dimensions.1.Name=command &Instances.N.Dimensions.1.Value=Specific Command Word

Object¶

Collected Tencent Cloud Redis object data structure, can be viewed in 「Infrastructure-Custom」

Logging¶

Slow Query Statistics¶

Prerequisites for Slow Query Statistics¶

Note 1: The code execution of this script depends on Redis instance object collection. If Redis custom object collection is not configured, the slow log script cannot collect slow log data.

Slow Query Statistics Installation Script¶

On top of the previous setup, you need to install another corresponding RDS Slow Query Statistics Log Collection Script.

In 「Manage / Script Market」, click and install the corresponding script package:

• "TrueWatch Integration (Tencent Cloud-Redis Slow Query Log Collection)" (ID: integration_tencentcloud_redis_slowlog)

After data synchronization is normal, you can view the data in TrueWatch's 「Logs」.

The reported data example is as follows:

{
    "measurement": "tencentcloud_redis_slow_log",
    "tags": {
        "BillingMode" : "0",
        "Client"      : "",
        "Engine"      : "Redis",
        "InstanceId"  : "crs-rha4zlon",
        "InstanceName": "crs-rha4zlon",
        "Node"        : "6d5d8cc6fxxxx",
        "Port"        : "6379",
        "ProductType" : "standalone",
        "ProjectId"   : "0",
        "RegionId"    : "ap-shanghai",
        "Status"      : "2",
        "Type"        : "8",
        "WanIp"       : "172.17.0.9",
        "ZoneId"      : "200002",
        "name"        : "crs-xxxx"
    },
    "fields": {
        "Command"    : "config",
        "CommandLine": "config get whitelist-ips",
        "Duration"   : 1,
        "ExecuteTime": "2022-07-22 18:00:28",
        "message"    : "{Instance JSON Data}"
    }
}

Partial parameter descriptions are as follows

Note: Fields in tags, fields may change with subsequent updates Note 1: tags.name value is the instance ID, used as a unique identifier. Note 2: fields.message is a JSON serialized string.
