来自vsphere的scollector标记度量

Question

只是一个关于收藏家贴标签的问题。我有一个配置文件，如下所示：

Host = "bosun01:80"
BatchSize = 5000

[Tags]
  customer = "Admin"
  environment = "bosun"
  datacenter = "SITE1"

[[Vsphere]]
  Host = "CUST2SITE1VC01.F.Q.D.N"
  User = "user"
  Password = "pass"

[[Vsphere]]
  Host = "CUST3SITE1VC01.F.Q.D.N"
  User = "user"
  Password = "pass"

[[Vsphere]]
  Host = "CUST4SITE1VC01.F.Q.D.N"
  User = "user"
  Password = "pass"

[[Vsphere]]
  Host = "CUST4SITE2VC01.F.Q.D.N"
  User = "user"
  Password = "pass"

[[TagOverride]]
  CollectorExpr = "Vsphere"
    [TagOverride.MatchedTags]
      Host = '^(?P<customer>.{5})(?P<datacenter>.{5})(?P<environment>)\.[.]+'

我们可以从不同的vsphere服务器检索和标记数据。

我对docs的理解是，这将根据Vsphere主机名中的regex提供许多不同的标记值。初始标记用于本地主机，我们使用重写来自Vsphere的数据。

然而，当我实现这一点时，我注意到这些指标是与原始环境标记"bosun“一起出现的，而不是被应用的覆盖。

我尝试了另一个配置：

Host = "bosun01:80"
BatchSize = 5000

[Tags]
  customer = "Admin"
  environment = "bosun"
  datacenter = "SITE1"

[[Vsphere]]
  Host = "CUST2SITE1VC01.F.Q.D.N"
  User = "user"
  Password = "pass"
  [[TagOverride]]
    [TagOverride.Tags]
      environment = "Env01"

[[Vsphere]]
  Host = "CUST3SITE1VC01.F.Q.D.N"
  User = "user"
  Password = "pass"
  [[TagOverride]]
    [TagOverride.Tags]
      environment = "Env02"


[[Vsphere]]
  Host = "CUST4SITE1VC01.F.Q.D.N"
  User = "user"
  Password = "pass"
  [[TagOverride]]
    [TagOverride.Tags]
      environment = "Env03"


[[Vsphere]]
  Host = "CUST4SITE2VC01.F.Q.D.N"
  User = "user"
  Password = "pass"
  [[TagOverride]]
    [TagOverride.Tags]
      environment = "Env04"

但是我看到了类似的行为(最后一个环境标记应用于所有的vpshere数据)，所以我不太确定我在哪里出错。

有人能帮我弄清楚我哪里出了问题吗？

更新

根据格雷格下面的回答，我的问题是我没有完全正确的CollectorExpr。

使用scollector -l，我能够得到正确的CollectorExpr。

# ./scollector-linux-amd64 -l | grep vsphere
vsphere-CUST1-SITE1-MGMTVC01
vsphere-CUST1-SITE2-MGMTVC01
vsphere-CUST1-SITE1-CLIVC01
vsphere-CUST1-SITE2-CLIVC01
#

我们的配置(对于那些寻找示例的人)最终得到的结果如下：

Host = "hwbosun01:80"
BatchSize = 5000

[Tags]
  customer = "Customer1"
  environment = "bosun"
  datacenter = "eq"

[[Vsphere]]
  Host = "CUST1-SITE1-MGMTVC01"
  User = "user"
  Password = "pass"

[[Vsphere]]
  Host = "CUST1-SITE2-MGMTVC01"
  User = "user"
  Password = "pass"

[[Vsphere]]
  Host = "CUST1-SITE1-CLIVVC01"
  User = "user"
  Password = "pass"

[[Vsphere]]
  Host = "CUST-SITE1-CLIVVC01"
  User = "user"
  Password = "pass"

[[TagOverride]]
  CollectorExpr = "CUST-SITE1-MGMTVC01"
    [TagOverride.Tags]
      environment = "vsphere.mgmt"
      datacenter = 'site1'

[[TagOverride]]
  CollectorExpr = "CUST-SITE1-MGMTVC01"
    [TagOverride.Tags]
      environment = "vsphere.mgmt"
      datacenter = 'site2'

[[TagOverride]]
  CollectorExpr = "CUST-SITE1-CLIVC01"
    [TagOverride.Tags]
      environment = "vsphere.mgmt"
      datacenter = 'site1'

[[TagOverride]]
  CollectorExpr = "CUST-SITE1-CLIVC01"
    [TagOverride.Tags]
      environment = "vsphere.mgmt"
      datacenter = 'site2'

我认为CollectorExpr是一个正则表达式，必须与scollector -l的输出或scollector.collector.duration度量中使用的收集器标记值匹配。我们的vsphere实例获取vsphere-ny-vsphere02的标记值，而vsphere-nyhq-vsphere01的标记值为nyhq-vsphere01。下列设置应与这些收集器名称匹配：

[[TagOverride]]
  CollectorExpr = "vsphere-ny-"
    [TagOverride.Tags]
      datacenter = 'ny'

[[TagOverride]]
  CollectorExpr = "vsphere-nyhq-"
    [TagOverride.Tags]
      datacenter = 'nyhq'

使用[TagOverride.MatchedTags]而不是[TagOverride.Tags]应该可以从主机名中提取值，但请记住，除非在scollector.toml文件中设置FullHost = true，否则所有主机名都会被截断为它们的短名称(没有FQDN)。我猜您的设置失败了，因为CollectorExpr不正确。试一试如下：

[[TagOverride]]
  CollectorExpr = "vsphere-"
    [TagOverride.MatchedTags]
      Host = '^(?P<customer>.{5})(?P<datacenter>.{5})(?P<environment>[^.]+)'

如果这不起作用，尝试在dev环境中使用“TagOverride.Tags”，看看是否可以向这些度量标准中添加测试标记/值。
