Prometheus Metrics

# Read metrics from one or many prometheus clients
[[inputs.prometheus]]
## An array of urls to scrape metrics from.
  urls = ["http://localhost:9100/metrics"]
 
  ## Metric version controls the mapping from Prometheus metrics into Telegraf metrics.
  ## See "Metric Format Configuration" in plugins/inputs/prometheus/README.md for details.
  ## Valid options: 1, 2
  # metric_version = 1
 
  ## Url tag name (tag containing scrapped url. optional, default is "url")
  # url_tag = "url"
 
  ## Whether the timestamp of the scraped metrics will be ignored.
  ## If set to true, the gather time will be used.
  # ignore_timestamp = false
 
  ## An array of Kubernetes services to scrape metrics from.
  # kubernetes_services = ["http://my-service-dns.my-namespace:9100/metrics"]
 
  ## Kubernetes config file to create client from.
  # kube_config = "/path/to/kubernetes.config"
 
  ## Scrape Pods
  ## Enable scraping of k8s pods. Further settings as to which pods to scape
  ## are determiend by the 'method' option below. When enabled, the default is
  ## to use annotations to determine whether to scrape or not.
  # monitor_kubernetes_pods = false
 
  ## Scrape Pods Method
  ## annotations: default, looks for specific pod annotations documented below
  ## settings: only look for pods matching the settings provided, not
  ##   annotations
  ## settings+annotations: looks at pods that match annotations using the user
  ##   defined settings
  # monitor_kubernetes_pods_method = "annotations"
 
  ## Scrape Pods 'annotations' method options
  ## If set method is set to 'annotations' or 'settings+annotations', these
  ## annotation flags are looked for:
  ## - prometheus.io/scrape: Required to enable scraping for this pod. Can also
  ##     use 'prometheus.io/scrape=false' annotation to opt-out entirely.
  ## - prometheus.io/scheme: If the metrics endpoint is secured then you will
  ##     need to set this to 'https' & most likely set the tls config
  ## - prometheus.io/path: If the metrics path is not /metrics, define it with
  ##     this annotation
  ## - prometheus.io/port: If port is not 9102 use this annotation
 
  ## Scrape Pods 'settings' method options
  ## When using 'settings' or 'settings+annotations', the default values for
  ## annotations can be modified using with the following options:
  # monitor_kubernetes_pods_scheme = "http"
  # monitor_kubernetes_pods_port = "9102"
  # monitor_kubernetes_pods_path = "/metrics"
 
  ## Get the list of pods to scrape with either the scope of
  ## - cluster: the kubernetes watch api (default, no need to specify)
  ## - node: the local cadvisor api; for scalability. Note that the config node_ip or the environment variable NODE_IP must be set to the host IP.
  # pod_scrape_scope = "cluster"
 
  ## Only for node scrape scope: node IP of the node that telegraf is running on.
  ## Either this config or the environment variable NODE_IP must be set.
  # node_ip = "10.180.1.1"
 
  ## Only for node scrape scope: interval in seconds for how often to get updated pod list for scraping.
  ## Default is 60 seconds.
  # pod_scrape_interval = 60
 
  ## Restricts Kubernetes monitoring to a single namespace
  ##   ex: monitor_kubernetes_pods_namespace = "default"
  # monitor_kubernetes_pods_namespace = ""
  ## The name of the label for the pod that is being scraped.
  ## Default is 'namespace' but this can conflict with metrics that have the label 'namespace'
  # pod_namespace_label_name = "namespace"
  # label selector to target pods which have the label
  # kubernetes_label_selector = "env=dev,app=nginx"
  # field selector to target pods
  # eg. To scrape pods on a specific node
  # kubernetes_field_selector = "spec.nodeName=$HOSTNAME"
 
  ## Filter which pod annotations and labels will be added to metric tags
  #
  # pod_annotation_include = ["annotation-key-1"]
  # pod_annotation_exclude = ["exclude-me"]
  # pod_label_include = ["label-key-1"]
  # pod_label_exclude = ["exclude-me"]
 
  # cache refresh interval to set the interval for re-sync of pods list.
  # Default is 60 minutes.
  # cache_refresh_interval = 60
 
  ## Scrape Services available in Consul Catalog
  # [inputs.prometheus.consul]
  #   enabled = true
  #   agent = "http://localhost:8500"
  #   query_interval = "5m"
 
  ## Use bearer token for authorization. ('bearer_token' takes priority)
  # bearer_token = "/path/to/bearer/token"
  ## OR
  # bearer_token_string = "abc_123"
 
  ## HTTP Basic Authentication username and password. ('bearer_token' and
  ## 'bearer_token_string' take priority)
  # username = ""
  # password = ""
 
  ## Optional custom HTTP headers
  # http_headers = {"X-Special-Header" = "Special-Value"}
 
  ## Specify timeout duration for slower prometheus clients (default is 5s)
  # timeout = "5s"
 
  ## deprecated in 1.26; use the timeout option
  # response_timeout = "5s"
 
  ## HTTP Proxy support
  # use_system_proxy = false
  # http_proxy_url = ""
 
  ## Optional TLS Config
  # tls_ca = /path/to/cafile
  # tls_cert = /path/to/certfile
  # tls_key = /path/to/keyfile
 
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false
 
  ## Use the given name as the SNI server name on each URL
  # tls_server_name = "myhost.example.org"
 
  ## TLS renegotiation method, choose from "never", "once", "freely"
  # tls_renegotiation_method = "never"
 
  ## Enable/disable TLS
  ## Set to true/false to enforce TLS being enabled/disabled. If not set,
  ## enable TLS only if any of the other options are specified.
  # tls_enable = true
 
  ## Control pod scraping based on pod namespace annotations
  ## Pass and drop here act like tagpass and tagdrop, but instead
  ## of filtering metrics they filters pod candidates for scraping
  #[inputs.prometheus.namespace_annotation_pass]
  # annotation_key = ["value1", "value2"]
  #[inputs.prometheus.namespace_annotation_drop]
  # some_annotation_key = ["dont-scrape"]
