Hi,
Could you please gimme an example how did you configure the
additionalScrapeConfigs? My testing case is quite simple. I wanted to feed 2
VMs (one Windows wmi exporter, one Linux node exporter) metrics to Prometheus
on Azure Kubernetes, which was deployed by stable/prometheus-operator helm
chart.
I see in the values.yaml file, there is a section for additionalScrapeConfigs
below.. Shall I add config in the values.yaml directly? Or I have to create a
prometheus-additional.yaml like below and make a secret out of this
configuration? The doc is not clear. If I do this way, how does Prometheus pick
this additional scrape_config up after secret is created??
prometheus-additional.yaml
- job_name: “node_exporter”
static_configs:
- targets: ['xx.xx.xx.xx:9100']
Default values.yaml
## The scrape configuraiton example below will find master nodes, provided they
have the name .*mst.*, relabel the
## port to 2379 and allow etcd scraping provided it is running on all
Kubernetes master nodes
##
additionalScrapeConfigs: []
# - job_name: kube-etcd
# kubernetes_sd_configs:
# - role: node
# scheme: https
# tls_config:
# ca_file: /etc/prometheus/secrets/etcd-client-cert/etcd-ca
# cert_file: /etc/prometheus/secrets/etcd-client-cert/etcd-client
# key_file: /etc/prometheus/secrets/etcd-client-cert/etcd-client-key
# relabel_configs:
# - action: labelmap
# regex: __meta_kubernetes_node_label_(.+)
# - source_labels: [__address__]
# action: replace
# targetLabel: __address__
# regex: ([^:;]+):(\d+)
# replacement: ${1}:2379
# - source_labels: [__meta_kubernetes_node_name]
# action: keep
# regex: .*mst.*
# - source_labels: [__meta_kubernetes_node_name]
# action: replace
# targetLabel: node
# regex: (.*)
# replacement: ${1}
# metric_relabel_configs:
# - regex:
(kubernetes_io_hostname|failure_domain_beta_kubernetes_io_region|beta_kubernetes_io_os|beta_kubernetes_io_arch|beta_kubernetes_io_instance_type|failure_domain_beta_kubernetes_io_zone)
# action: labeldrop
