Question

有没有办法轻松找出EC2实例上次停止的时间？通过查看ec2.get_only_instances()变量，我可以从launch_time获取启动时间。但是，它看起来好像停止时间存储在任何元数据中。

我们可能会使用rc#.d脚本来实现此功能，但我只是想知道是否可以通过boto获取该信息。

Answer 1

您可以使用reason个实例的stopped变量：

import boto.ec2
conn = boto.ec2.connect_to_region("eu-west-1")
reservations = conn.get_all_instances()
for r in reservations:
    for i in r.instances:
        if i.state == 'stopped':
            print "%s [%s] %s" % (i.id, i.state, i.reason)

输出：

i-11223344 [stopped] User initiated (2013-12-20 13:59:08 GMT)

这也适用于terminated个实例（只要它们仍然显示）。

Answer 2

我认为更好的做法是：

import boto.ec2
conn = boto.ec2.connect_to_region("eu-west-1")
reservations = conn.get_all_instances()
instances = []
for reservation in reservations:
    for instance in reservation.instances:
        if "Name" in instance.tags.keys():
            instances.append((instance.tags["Name"],
                              instance.get_console_output().timestamp))

您也可以替换if并获取所需内容，但instance.get_console_output().timestamp是获取实例已停止时间戳的正确方法

请看这个，它返回ec2名称中的时间戳，它在aws停止并且颜色为红色。请注意，在运行之前设置包含凭证的aws配置文件环境。

import boto.ec2    

class i_color:
  red   = '\033[31m'
  reset = '\033[0m'

def name(i):
  if 'Name' in i.tags:
    n = i.tags['Name']
    n = i_color.red + n + i_color.reset
  return n

conn = boto.ec2.connect_to_region("us-east-1")
reservations = conn.get_all_instances()
for r in reservations:
    for i in r.instances:
        if i.state == 'stopped':
           print "%s [%s] %s" % (name(i),i.state,i.reason)

示例输出：

test-ec2-temp05 [stopped] User initiated (2016-08-02 09:00:43 GMT)

Answer 4

代码：

import boto3
from prettytable import PrettyTable

cli = boto3.client('ec2')
resp = cli.describe_instances(
    Filters=[
        {
            'Name': 'instance-state-name',
            'Values': [
                'stopped',
            ]
        },
    ],
    MaxResults=1000,
)

table = PrettyTable()
table.field_names = ["Name", "ID", "State", "Reason"]

for r in resp["Reservations"]:
    for i in r["Instances"]:
        name = ''
        for t in i["Tags"]:
            if t["Key"] == "Name":
                name = t["Value"]

        table.add_row([name, i["InstanceId"], i["State"]["Name"],
                       i["StateTransitionReason"]])

print(table.get_string(sortby="Reason"))

输出：

+-------------------+---------------------+---------+------------------------------------------+
|       Name        |          ID         |  State  |                  Reason                  |
+-------------------+---------------------+---------+------------------------------------------+
| server-name-tag-1 | i-0a12b3056c789012a | stopped | User initiated (2017-02-27 20:20:00 GMT) |
| server-name-tag-2 | i-1b12b3956c789012b | stopped | User initiated (2018-02-27 20:20:00 GMT) |
| server-name-tag-3 | i-2c12b3856c789012c | stopped | User initiated (2019-02-27 20:20:00 GMT) |
| server-name-tag-4 | i-3d12b3756c789012d | stopped | User initiated (2020-02-27 20:20:00 GMT) |
