Configuration¶

Install Func¶

It is recommended to enable Guance Integration - Extension - Managed Func: all prerequisites are automatically installed. Please continue with the script installation.

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

It is recommended to deploy the GSE version.

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 ECS cloud resource monitoring data, we install the corresponding collection script: "Guance Integration (Alibaba Cloud - MongoDB Replica Set Collection)" (ID: guance_aliyun_mongodb)

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

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

After enabling, you can see the corresponding automatic trigger configuration under "Manage / Automatic Trigger Configuration." Click 【Execute】to execute immediately without waiting for the scheduled time. After a short while, you can view the execution task records and corresponding logs.

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

We default to collecting some configurations, for more details see the metrics section.

Customize Cloud Object Metrics

Verification¶

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

Metrics¶

By configuring Alibaba Cloud - Cloud Monitoring, the following default metrics are collected. More metrics can be collected through configuration. For more metrics, please refer to: Alibaba Cloud Cloud Monitoring Metrics Details

Cloud Database MongoDB Edition - Replica Set¶

Cloud Database MongoDB Edition - Sharded Cluster¶

Cloud Database MongoDB Edition - Single Node Instance¶

Objects¶

The structure of Alibaba Cloud MongoDB objects collected can be viewed under "Infrastructure - Custom."

  "measurement": "aliyun_mongodb",
  "tags": {
    "name"                 : "dds-bpxxxxxxxx",

Logs¶

Slow Query Logs¶

Prerequisites¶

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

Install Slow Query Collection Script¶

On top of the previous steps, you need to install another script corresponding to MongoDB Slow Query Collection

In the "Script Market - Official Script Market," go to "Details" and click to install the corresponding script package:

• "Guance Integration (Alibaba Cloud - MongoDB Slow Query Log Collection)" (ID: guance_aliyun_mongodb)

After the data synchronizes normally, you can view the data in the "Logs" section of Guance.

An example of the reported data is as follows:

{
  "measurement": "aliyun_mongodb_slowlog",
  "tags": {
    "name"                 : "dds-bpxxxxxxxx",
    "DBInstanceType"       : "replicate",
    "ChargeType"           : "PrePaid",
    "Engine"               : "MongoDB",
    "DBInstanceClass"      : "dds.xxxxxxxx",
    "DBInstanceId"         : "dds-bpxxxxxxx",
    "ZoneId"               : "cn-hangzhou",
    "RegionId"             : "cn-hangzhou-h",
    "VPCId"                : "vpc-bpxxxxxxxx",
    "EngineVersion"        : "4.2",
    "CurrentKernelVersion" : "mongodb_20210204_4.0.14",
    "StorageEngine"        : "WiredTiger",
    "DBInstanceDescription": "Business System",
    "DBName"               : "local",
    "AccountName"          : "AliCloud Account for Script Development",
    "HostAddress"          : "11.xxx.xxx.xx",
    "TableName"            : "oplog",
  },
  "fields": {
    "SQLText"           : "{SQL Statement}",
    "ExecutionStartTime": "1",
    "QueryTimes"        : "1",
    "ReturnRowCounts"   : "1",
    "KeysExamined"      : "1",
    "DocsExamined"      : "1",
  }
}

Some parameter descriptions are as follows:

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

Note: fields.message is a JSON serialized string.
