# GitHub Input Plugin
|
|
||||||
|
|
||||||
Gather repository information from [GitHub][] hosted repositories.
|
|
||||||
|
|
||||||
**Note:** Telegraf also contains the [webhook][] input which can be used as an
|
|
||||||
alternative method for collecting repository information.
|
|
||||||
|
|
||||||
### Configuration
|
|
||||||
|
|
||||||
```toml
|
|
||||||
[[inputs.github]]
|
|
||||||
## List of repositories to monitor
|
|
||||||
repositories = [
|
|
||||||
"influxdata/telegraf",
|
|
||||||
"influxdata/influxdb"
|
|
||||||
]
|
|
||||||
|
|
||||||
## Github API access token. Unauthenticated requests are limited to 60 per hour.
|
|
||||||
# access_token = ""
|
|
||||||
|
|
||||||
## Github API enterprise url. Github Enterprise accounts must specify their base url.
|
|
||||||
# enterprise_base_url = ""
|
|
||||||
|
|
||||||
## Timeout for HTTP requests.
|
|
||||||
# http_timeout = "5s"
|
|
||||||
```
|
|
||||||
|
|
||||||
### Metrics
|
|
||||||
|
|
||||||
- github_repository
|
|
||||||
- tags:
|
|
||||||
- name - The repository name
|
|
||||||
- owner - The owner of the repository
|
|
||||||
- language - The primary language of the repository
|
|
||||||
- license - The license set for the repository
|
|
||||||
- fields:
|
|
||||||
- forks (int)
|
|
||||||
- open_issues (int)
|
|
||||||
- networks (int)
|
|
||||||
- size (int)
|
|
||||||
- subscribers (int)
|
|
||||||
- stars (int)
|
|
||||||
- watchers (int)
|
|
||||||
|
|
||||||
When the [internal][] input is enabled:
|
|
||||||
|
|
||||||
+ internal_github
|
|
||||||
- tags:
|
|
||||||
- access_token - An obfuscated reference to the configured access token or "Unauthenticated"
|
|
||||||
- fields:
|
|
||||||
- limit - How many requests you are limited to (per hour)
|
|
||||||
- remaining - How many requests you have remaining (per hour)
|
|
||||||
- blocks - How many requests have been blocked due to rate limit
|
|
||||||
|
|
||||||

# Prometheus Input Plugin
|
|
||||||
|
|
||||||
The prometheus input plugin gathers metrics from HTTP servers exposing metrics
|
|
||||||
in Prometheus format.
|
|
||||||
|
|
||||||
### Configuration:
|
|
||||||
|
|
||||||
```toml
|
|
||||||
# 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. When using the prometheus_client output, use the same
|
|
||||||
## value in both plugins to ensure metrics are round-tripped without
|
|
||||||
## modification.
|
|
||||||
##
|
|
||||||
## example: metric_version = 1; deprecated in 1.13
|
|
||||||
## metric_version = 2; recommended version
|
|
||||||
# metric_version = 1
|
|
||||||
|
|
||||||
## 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 Kubernetes pods for the following prometheus annotations:
|
|
||||||
## - prometheus.io/scrape: Enable scraping for this pod
|
|
||||||
## - 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
|
|
||||||
# monitor_kubernetes_pods = true
|
|
||||||
## Restricts Kubernetes monitoring to a single namespace
|
|
||||||
## ex: monitor_kubernetes_pods_namespace = "default"
|
|
||||||
# monitor_kubernetes_pods_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"
|
|
||||||
|
|
||||||
## 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 = ""
|
|
||||||
|
|
||||||
## Specify timeout duration for slower prometheus clients (default is 3s)
|
|
||||||
# response_timeout = "3s"
|
|
||||||
|
|
||||||
## 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
|
|
||||||
```
|
|
||||||
|
|
||||||
`urls` can contain a unix socket as well. If a different path is required (default is `/metrics` for both http[s] and unix) for a unix socket, add `path` as a query parameter as follows: `unix:///var/run/prometheus.sock?path=/custom/metrics`
|
|
||||||
|
|
||||||
#### Kubernetes Service Discovery
|
|
||||||
|
|
||||||
URLs listed in the `kubernetes_services` parameter will be expanded
|
|
||||||
by looking up all A records assigned to the hostname as described in
|
|
||||||
[Kubernetes DNS service discovery](https://kubernetes.io/docs/concepts/services-networking/service/#dns).
|
|
||||||
|
|
||||||
This method can be used to locate all
|
|
||||||
[Kubernetes headless services](https://kubernetes.io/docs/concepts/services-networking/service/#headless-services).
|
|
||||||
|
|
||||||
#### Kubernetes scraping
|
|
||||||
|
|
||||||
Enabling this option will allow the plugin to scrape for prometheus annotation on Kubernetes
|
|
||||||
pods. Currently, you can run this plugin in your kubernetes cluster, or we use the kubeconfig
|
|
||||||
file to determine where to monitor.
|
|
||||||
Currently the following annotation are supported:
|
|
||||||
|
|
||||||
* `prometheus.io/scrape` Enable scraping for this pod.
|
|
||||||
* `prometheus.io/scheme` If the metrics endpoint is secured then you will need to set this to `https` & most likely set the tls config. (default 'http')
|
|
||||||
* `prometheus.io/path` Override the path for the metrics endpoint on the service. (default '/metrics')
|
|
||||||
* `prometheus.io/port` Used to override the port. (default 9102)
|
|
||||||
|
|
||||||
Using the `monitor_kubernetes_pods_namespace` option allows you to limit which pods you are scraping.
|
|
||||||
|
|
||||||
#### Bearer Token
|
|
||||||
|
|
||||||
If set, the file specified by the `bearer_token` parameter will be read on
|
|
||||||
each interval and its contents will be appended to the Bearer string in the
|
|
||||||
Authorization header.
|
|
||||||
|
|
||||||
### Usage for Caddy HTTP server
|
|
||||||
|
|
||||||
If you want to monitor Caddy, you need to use Caddy with its Prometheus plugin:
|
|
||||||
|
|
||||||
* Download Caddy+Prometheus plugin [here](https://caddyserver.com/download/linux/amd64?plugins=http.prometheus)
|
|
||||||
* Add the `prometheus` directive in your `CaddyFile`
|
|
||||||
* Restart Caddy
|
|
||||||
* Configure Telegraf to fetch metrics on it:
|
|
||||||
|
|
||||||
```toml
|
|
||||||
[[inputs.prometheus]]
|
|
||||||
# ## An array of urls to scrape metrics from.
|
|
||||||
urls = ["http://localhost:9180/metrics"]
|
|
||||||
```
|
|
||||||
|
|
||||||
> This is the default URL where Caddy Prometheus plugin will send data.
|
|
||||||
> For more details, please read the [Caddy Prometheus documentation](https://github.com/miekg/caddy-prometheus/blob/master/README.md).
|
|
||||||
|
|
||||||
### Metrics:
|
|
||||||
|
|
||||||
Measurement names are based on the Metric Family and tags are created for each
|
|
||||||
label. The value is added to a field named based on the metric type.
|
|
||||||
|
|
||||||
All metrics receive the `url` tag indicating the related URL specified in the
|
|
||||||
Telegraf configuration. If using Kubernetes service discovery the `address`
|
|
||||||
tag is also added indicating the discovered ip address.
|
|
||||||
|
|
||||||
