Alibaba Cloud Redis Standard Edition¶

Alibaba Cloud Redis Standard Edition Metrics display, including CPU usage, memory usage, disk read/write, network traffic, access per second, etc.

Configuration¶

Install Func¶

It is recommended to enable Guance integration - extension - hosted Func: all prerequisites are automatically installed. Please continue with the script installation.

If you deploy Func on your own, refer to Self-deployed Func

Installation Script¶

Note: Please prepare an Alibaba Cloud AK that meets the requirements in advance (for simplicity, you can directly grant global read-only permission ReadOnlyAccess)

To synchronize monitoring data of Alibaba Cloud Redis Standard Edition, we install the corresponding collection script: Guance Integration (Alibaba Cloud - Redis Collection) (ID: guance_aliyun_redis).

After clicking 【Install】, enter the corresponding parameters: Alibaba Cloud AK, Alibaba Cloud account name.

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

In addition, you can see the corresponding automatic trigger configuration in the 「Manage / Automatic Trigger Configuration」. Click 【Execute】 to run it immediately without waiting for the scheduled time. After a short wait, you can view the execution task records and corresponding logs.

We collect some configurations by default; for more details, see the Metrics section.

Verification¶

1. In 「Manage / Automatic Trigger Configuration」, confirm whether the corresponding task has the corresponding automatic trigger configuration, and check the corresponding task records and logs for any anomalies.
2. In the Guance platform, under 「Infrastructure / Custom」, check if there is asset information.
3. In the Guance platform, under 「Metrics」, check if there is corresponding monitoring data.

Metrics¶

After configuring Alibaba Cloud - Cloud Monitoring, the default metric set is as follows. You can collect more metrics via configuration Alibaba Cloud Cloud Monitoring Metric Details

Objects¶

The collected Alibaba Cloud redis object data structure can be seen in 「Infrastructure - Custom」.

{
  "measurement": "aliyun_redis",
  "tags": {
    "name"            : "r-bp12xxxxxxx",
    "InstanceId"      : "r-bp12vxxxxxxxxx",
    "RegionId"        : "cn-hangzhou",
    "ZoneId"          : "cn-hangzhou-h",
    "InstanceClass"   : "redis.master.small.default",
    "EngineVersion"   : "5.0",
    "ChargeType"      : "PrePaid",
    "ConnectionDomain": "r-bp12vxxxxxxx.redis.rds.aliyuncs.com",
    "NetworkType"     : "VPC",
    "PrivateIp"       : "xxxxxx",
    "Port"            : "6379",
    "InstanceName"    : "xxx System",
    "InstanceType"    : "Redis",
    "InstanceStatus"  : "Normal"
  },
  "fields": {
    "Capacity"  : "1024",
    "EndTime"   : "2022-12-13T16:00:00Z",
    "CreateTime": "2021-01-11T09:35:51Z",
    "Accounts"  : "[{JSON Account Information}]",
    "message"   : "{JSON Instance Data}"
  }
}

Logs¶

Slow Queries¶

Prerequisites¶

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

Installation Script¶

On top of the previous setup, you need to install another script for Redis Slow Query Log Collection.

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

• 「Guance Integration (Alibaba Cloud - Redis Slow Query Log Collection)」(ID: guance_aliyun_redis_slowlog)

After the data synchronization is normal, you can view the data in the 「Logs」 section of Guance.

An example of the reported data is as follows:

{
  "measurement": "aliyun_redis_slowlog",
  "tags": {
      "name"            : "r-bp1c4xxxxxxxofy2vm",
      "Account"         : "(null)",
      "IPAddress"       : "172.xx.x.201",
      "AccountName"     : "(null)",
      "DBName"          : "3",
      "NodeId"          : "(null)",
      "ChargeType"      : "PrePaid",
      "ConnectionDomain": "r-bpxxxxxxxxxxy2vm.redis.rds.aliyuncs.com",
      "EngineVersion"   : "4.0",
      "InstanceClass"   : "redis.master.small.default",
      "InstanceId"      : "r-bpxxxxxxxxxxxxxxx2vm",
      "InstanceName"    : "xx3.0-xx System",
      "NetworkType"     : "VPC",
      "Port"            : "6379",
      "PrivateIp"       : "172.xxx.xx.200",
      "RegionId"        : "cn-hangzhou",
      "ZoneId"          : "cn-hangzhou-h"
  },
  "fields": {
    "Command"    : "latency:eventloop",
    "ElapsedTime": 192000,
    "ExecuteTime": "2022-07-26T03:18:36Z",
    "message"    : "{JSON Instance Data}"
  }
}

Descriptions of some parameters are as follows:

Note: Fields in tags, fields may change with subsequent updates.

Note: fields.message is a JSON serialized string.
