scollector

Question

只是关于 scollector 标记的问题。我有一个如下所示的配置文件：

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>)\.[.]+'

我们的想法是我们可以从不同的 vsphere 服务器检索和标记数据。

我对文档的理解是，这将根据 Vsphere 主机名的正则表达式为我们提供许多不同的标签值。初始标签用于本地主机，我们使用覆盖来自 Vsphere 的数据。

但是，当我实施此操作时，我注意到这些指标随 "bosun" 的原始环境标签一起出现，而不是应用覆盖。

我试过另一种配置：

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"

但我看到了类似的行为（最后一个环境标签应用于所有 vpshere 数据），所以我不太确定哪里出错了。

有人可以帮助我了解我哪里出错了吗？

更新

根据下面 Greg 的回答，我的问题是我没有完全正确地设置 CollectorExpr。

使用 scollector -l 我能够想出正确的 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）最终是这样的：

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'

Answer 1

我认为 CollectorExpr 是一个正则表达式，必须与 scollector -l 的输出或 scollector.collector.duration 指标中使用的收集器标记值相匹配。我们的 vsphere 实例获取 ny-vsphere02 的 vsphere-ny-vsphere02 标签值和 nyhq-vsphere01 的 vsphere-nyhq-vsphere01 标签值。以下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，除非您设置 FullHost，否则所有主机名都会被截断为其短名称（无 FQDN） = 在 scollector.toml 文件中为真。我的猜测是您的设置失败，因为 CollectorExpr 不正确。尝试类似的东西：

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

如果这不起作用，请尝试在开发环境中使用“[TagOverride.Tags]”，看看是否可以将测试 tags/values 添加到这些指标。
