Hi Experts,
I configured blackbox-exporter to monitor kubernetes services. But I didn't
managed to make it work
It shows targets down in Prometheus with error connection reset by peer.
Here is my settings:
*blackbox config:*
modules:
http_2xx:
prober: http
http:
method: GET
preferred_ip_protocol: "ip4"
valid_status_codes: [200]
http_post_2xx:
prober: http
http:
method: POST
http_kubernetes_service:
prober: http
timeout: 5s
http:
headers:
Accept: "*/*"
Accept-Language: "en-US"
tls_config:
ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
bearer_token_file:
/var/run/secrets/kubernetes.io/serviceaccount/token
preferred_ip_protocol: "ip4"
*Prometheus additional-scrape-configs*
- job_name: blackbox-exporter-kubernetes-services
tls_config:
ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
metrics_path: /probe
params:
module: [http_2xx]
kubernetes_sd_configs:
- role: service
relabel_configs:
- source_labels:
[__meta_kubernetes_service_annotation_prometheus_io_probed]
action: keep
regex: true
- source_labels: [__address__]
target_label: __param_target
- target_label: __address__
replacement:
monitoring-blackbox-exporter.kyma-system.svc.cluster.local:9115
- source_labels: [__param_target]
target_label: instance
- action: labelmap
regex: __meta_kubernetes_service_label_(.+)
- source_labels: [__meta_kubernetes_namespace]
target_label: kubernetes_namespace
- source_labels: [__meta_kubernetes_service_name]
target_label: kubernetes_name
*Error In Prometheus Targets*
Get
http://monitoring-blackbox-exporter.kyma-system.svc.cluster.local:9115/probe?module=http_2xx&target=kiali.my-ns.svc%3A20001:
read tcp {ip}:40780->{ip}:9115: read: connection reset by peer
I have tried several suggestion and cannot solve this! Anyone could help,
appreciate it!
Thanks!
