如何在prometheus中使用blackbox_exporter ping目标
如何在prometheus中使用blackbox_exporter ping目标
提问于 2019-04-05 07:56:42
我正在尝试使用prometheus的blackbox_exporter对目标列表执行ping操作，但我似乎只能探测到blackbox_exporters，而不能探测我想要检查的实际目标。
我在blackbox中找不到任何关于在哪里列出目标的文档，所以我做了一个奇怪的假设，它使用了prometheus配置中提供的目标，但据我所知，这只是让prometheus相信有很多黑盒需要探测。
这是我的blackbox_exporter配置
modules:
icmp:
prober: icmp
timeout: 5s
icmp:
preferred_ip_protocol: ip4然而，当我访问blackbox的web GUI时，配置包含一堆我没有指定的参数。
modules:
icmp:
prober: icmp
timeout: 5s
http:
ip_protocol_fallback: true
tcp:
ip_protocol_fallback: true
icmp:
preferred_ip_protocol: ip4
ip_protocol_fallback: true
dns:
ip_protocol_fallback: true这是我的普罗米修斯配置
global:
scrape_interval: 15s
evaluation_interval: 15s
- job_name: 'blackbox'
metrics_path: /probe
params:
module: [icmp]
static_configs:
- targets:
- icmp-target1 # supposed to be a switch, router, pc or anything that responds to ping
- icmp-target2预期结果:在旅途中的某个地方，我希望我的目标会被blackbox和prometheus pinged，收集结果。
实际结果: Prometheus通过HTTP为其目标列表中列出的每个目标发送探测请求。

尽管有些令人困惑，但blackbox_exporter自述文件确实解释了如何配置它，请参阅Prometheus Configuration一节。
您的黑盒配置是正确的。
对于您的Prometheus配置，您需要类似以下内容。我假设黑盒导出器和普罗米修斯是并置的(因此是localhost)，否则就是适应。
# this is to scrape blackbox itself (this is optional)
- job_name: blackbox
static_configs:
- targets: ['localhost:9115']
- job_name: blackbox-ping
metrics_path: /probe
params:
module: [icmp]
static_configs:
- targets:
- 192.168.1.1 # <== Put here your targets
relabel_configs: # <== This comes from the blackbox exporter README
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: localhost:9115 # Blackbox exporter.另一个令人困惑的部分是回答这个问题：“如何将blackbox exporter用于多种协议，比如ICMP和HTTP?”在这种情况下，有多种选择，但更清楚的是每个协议都有一个部分。这就是我将ICMP探测器称为blackbox-ping的原因。假设我们还想拥有HTTP探测器，我们将添加另一个部分：
- job_name: blackbox-http
metrics_path: /probe
params:
module: [http_2xx]
static_configs:
- targets:
- https://www.google.com # <== your targets here
relabel_configs: # <== This comes from the blackbox exporter README
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: localhost:9115 # Blackbox exporter.您还需要相应的黑盒配置：
modules:
http_2xx: # <== This is the new section for HTTP
prober: http
timeout: 10s # <== This depends on what you want to do
http:
valid_status_codes: [] # Defaults to 2xx
method: HEAD # <== This depends on what you want to do
no_follow_redirects: true # <== this depends on what you want to do
icmp: # <== this is the one you already have
prober: icmp
timeout: 10s # <== This depends on what you want to do
icmp:
