Create a file named getlogs.json. Content example:

{
"topic": "",
"logstore": "logstore-a",
"project": "aliyun-test-project",
"toTime": "2021-05-28 15:33:00",
"offset": "0",
"query": "*|select status,COUNT(*) as pv group by status order by pv desc limit 3",
"line": "2",
"fromTime": "2021-05-28 15:18:00",
"reverse": "true"
}

We recommend that you specify a valid search or query statement that can be used to query data in the Simple Log Service console for the query parameter. For more information, see Log search overview and Log analysis overview.

Use the default account to query logs. Command example:

aliyunlog log get_logs --request="file://./getlogs.json" --format-output=json

The following result is returned:

[
  {
    "__source__": "",
    "__time__": "1622186280",
    "pv": "7928",
    "status": "200"
  },
  {
    "__source__": "",
    "__time__": "1622186280",
    "pv": "87",

  {
    "__source__": "",
    "__time__": "1622186280",
    "pv": "67",
    "status": "301"
  }
]

The query and analysis results show the top 3 statuses and the number of page views for each status.
