Tencent Cloud Redis¶

Tencent Cloud Redis metrics display, including connection count, request count, latency, and slow queries.

config¶

Install Func¶

Recommend opening 「Integrations - Extension - DataFlux Func (Automata)」: All preconditions are installed automatically, Please continue with the script installation

If you deploy Func yourself,Refer to Self-Deployment of Func

Installation script¶

Tip：Please prepare Tencent AK that meets the requirements in advance（For simplicity's sake,，You can directly grant the global read-only permissionReadOnlyAccess）

To synchronize the monitoring data of ECS cloud resources, we install the corresponding collection script：「Guance Integration（Tencent Cloud-RedisCollect）」(ID：guance_tencentcloud_redis)

Click 【Install】 and enter the corresponding parameters: Tencent AK, Tencent account name.。

tap【Deploy startup Script】，The system automatically creates Startup script sets，And automatically configure the corresponding startup script。

After this function is enabled, you can view the automatic triggering configuration in「Management / Crontab Config」。Click【Run】，you can immediately execute once, without waiting for a regular time。After a while, you can view task execution records and corresponding logs。

If you want to collect logs, you must enable the corresponding log collection script. If you want to collect bills, start the cloud bill collection script.

We collected some configurations by default, as described in the Metrics column Configuring Custom Cloud Object Metrics

Verify¶

1. In「Management / Crontab Config」check whether the automatic triggering configuration exists for the corresponding task,In addition, you can view task records and logs to check whether exceptions exist
2. On the observation cloud platform, click 「Infrastructure / Custom」 to check whether asset information exists
3. On the observation cloud platform, press 「Metrics」 to check whether monitoring data exists

Metric¶

Configure Tencent Cloud Redis monitoring. The default metric set is as follows. You can collect more metrics by configuring them Tencent Cloud Monitor Metrics Details

Overview of Parameters Corresponding to Each Dimension¶

Querying cloud database Proxy node monitoring data, the input parameter values 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

Querying cloud database Redis node monitoring data, the input parameter values 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

Querying cloud database Redis latency metrics (command dimension) monitoring data, the input parameter values 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

Object¶

The data structure of collected Tencent Cloud Redis object can be viewed in 'Infrastructure - Custom' where object data is available

{
  "measurement": "tencentcloud_redis",
  "tags": {
    "name"        : "crs-xxxx",
    "BillingMode" : "0",
    "Engine"      : "Redis",
    "InstanceId"  : "crs-xxxx",
    "InstanceName": "solution",
    "Port"        : "6379",
    "ProductType" : "standalone",
    "ProjectId"   : "0",
    "RegionId"    : "ap-shanghai",
    "Status"      : "2",
    "Type"        : "6",
    "WanIp"       : "172.x.x.x",
    "ZoneId"      : "200002"
  },

    "InstanceTitle"   : "Running",
    "Size"            : 1024,
    "message"         : "{Instance JSON data}"
  }
}

Logging¶

Slow Query Statistics¶

Prerequisites for Slow Query Statistics¶

Hint 1: The execution of this script relies on Redis instance object collection. If custom object collection for Redis is not configured, the slow log script will be unable to collect slow log data

Installation of Slow Query Statistics Script¶

Based on the previous steps, you need to install another script RDS Tencent Cloud-Redis Slow LogCollect

In the 'Management / Script Market' section, click and install the corresponding script package：

• 「Guance Integration（Tencent Cloud - Redis Slow Log Collect） 」(ID：guance_tencentcloud_redis_slowlog)

After successful data synchronization, you can view the data in the 'Logs' section of the Observation Cloud.

The example of reported data 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"    : "{InstanceJSONdata}"
    }
}

Partial parameter explanations are as follows:

Note: The fields in tags and fields may change in subsequent updates Hint 1: The value of tags.name is the instance ID, which serves as a unique identifier Hint 2: The value of fields.message is a JSON-serialized string
