Alibaba Cloud RDS PostgreSQL¶

Alibaba Cloud RDS PostgreSQL Metrics display, including CPU usage, memory usage, etc.

Configuration¶

Install Func¶

It is recommended to activate the Guance Integration - Extensions - DataFlux Func (Automata)

For self-deploying Func, refer to Self-deploy Func

Activate Script¶

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

Activate Script on DataFlux Func (Automata)¶

1. Log in to the Guance console.
2. Click the [Integration] menu, select [Cloud Account Management].
3. Click [Add Cloud Account], select [Alibaba Cloud], and fill in the required information on the interface. If the cloud account information has been configured before, ignore this step.
4. Click [Test]. After the test is successful, click [Save]. If the test fails, please check whether the relevant configuration information is correct and test again.
5. Click [Cloud Account Management]. You can see the added cloud account in the list. Click the corresponding cloud account to enter the details page.
6. Click the [Integration] button on the cloud account details page. Under the Not Installed list, find Alibaba Cloud RDS PostgreSQL, click the [Install] button, and install it in the pop-up installation interface.

Activate Script Manually¶

1. Log in to the Func console, click [Script Market], enter the Guance Script Market, and search for: integration_alibabacloud_rds.
2. After clicking [Install], enter the corresponding parameters: Alibaba Cloud AK ID, AK Secret, and account name.
3. Click [Deploy Startup Script]. The system will automatically create the Startup script set and automatically configure the corresponding startup script.
4. After activation, you can see the corresponding automatic trigger configuration in "Management / Automatic Trigger Configuration". Click [Execute] to execute it immediately once without waiting for the scheduled time. Wait a moment, you can view the execution task records and corresponding logs.

Verification¶

1. In "Management / Automatic Trigger Configuration", confirm whether the corresponding task has the corresponding automatic trigger configuration. You can also check the corresponding task records and logs to see if there are any exceptions.
2. In Guance, check if asset information exists in "Infrastructure / Custom".
3. In Guance, check in "Metrics" to see if there is corresponding monitoring data.

Metrics¶

After configuring Alibaba Cloud CloudMonitor, the default Measurement is as follows. More Metrics can be collected through configuration. Alibaba Cloud CloudMonitor Metric Details

The collected Alibaba Cloud RDS PostgreSQL object data structure can be seen in "Infrastructure - Custom"

Logging¶

Slow Query Details¶

Slow Query Details Prerequisites¶

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

Slow Query Details Installation Script¶

On the previous basis, you need to install another script package for RDS slow query details log collection.

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

• "Guance Integration (Alibaba Cloud-RDS Slow Query Details Log Collection)" (ID: integration_alibabacloud_rds_slowlog_record)

After the data is synchronized normally, you can view the data in the "Log" of Guance.

The reported data example is as follows:

{
  "measurement": "aliyun_rds_slowlog",
  "tags": {
    "name"                 : "rm-xxxxx",
    "DBName"               : "cloudcare_core",
    "DBInstanceId"         : "rm-bp1xxxxxxxxxx",
    "RegionId"             : "cn-hangzhou",
    "DBInstanceType"       : "Primary",
    "PayType"              : "Prepaid",
    "Engine"               : "MySQL",
    "DBInstanceClass"      : "rds.mysql.s2.large",
    "ZoneId"               : "cn-shanghai-h",
    "DBInstanceDescription": "Business system",
    "HostAddress"          : "xxxx",
    "UserName"             : "xxxx",
    "ClientHostName"       : "xxxx",
    "ApplicationName"      : "xxxx",

  },
  "fields": {
    "SQLHASH"                      : "436f9dd030e0a87920bbcd818b34f271",
    "SQLText"                      : "{SQL statement}",
    "QueryTimes"                   : 0,
    "QueryTimesMS"                 : 0,
    "ReturnRowCounts"              : 0,
    "ParseRowCounts"               : 0,
    "ExecutionStartTime"           : "2022-02-02T12:00:00Z",
    "CpuTime"                      : 1,
    "RowsAffectedCount"            : 0,
    "LastRowsAffectedCount"        : 0,
    "message"                      : "{Log JSON data}"
  }
}

Partial parameter descriptions are as follows:

Note: Fields such as CpuTime, RowsAffectedCount, LastRowsAffectedCount are only supported by SQL Server instances. Note: Fields in tags and fields may change with subsequent updates. Note: fields.message is a JSON serialized string.
