# HTTP Response Input Plugin
|
|
|
|
This input plugin checks HTTP/HTTPS connections.
|
|
|
|
### Configuration:
|
|
|
|
```
|
|
# HTTP/HTTPS request given an address a method and a timeout
|
|
[[inputs.http_response]]
|
|
## Deprecated in 1.12, use 'urls'
|
|
## Server address (default http://localhost)
|
|
# address = "http://localhost"
|
|
|
|
## List of urls to query.
|
|
# urls = ["http://localhost"]
|
|
|
|
## Set http_proxy (telegraf uses the system wide proxy settings if it's is not set)
|
|
# http_proxy = "http://localhost:8888"
|
|
|
|
## Set response_timeout (default 5 seconds)
|
|
# response_timeout = "5s"
|
|
|
|
## HTTP Request Method
|
|
# method = "GET"
|
|
|
|
## Whether to follow redirects from the server (defaults to false)
|
|
# follow_redirects = false
|
|
|
|
## Optional HTTP Request Body
|
|
# body = '''
|
|
# {'fake':'data'}
|
|
# '''
|
|
|
|
## Optional substring or regex match in body of the response (case sensitive)
|
|
# response_string_match = "\"service_status\": \"up\""
|
|
# response_string_match = "ok"
|
|
# response_string_match = "\".*_status\".?:.?\"up\""
|
|
|
|
## Optional TLS Config
|
|
# tls_ca = "/etc/telegraf/ca.pem"
|
|
# tls_cert = "/etc/telegraf/cert.pem"
|
|
# tls_key = "/etc/telegraf/key.pem"
|
|
## Use TLS but skip chain & host verification
|
|
# insecure_skip_verify = false
|
|
|
|
## HTTP Request Headers (all values must be strings)
|
|
# [inputs.http_response.headers]
|
|
# Host = "github.com"
|
|
|
|
## Interface to use when dialing an address
|
|
# interface = "eth0"
|
|
```
|
|
|
|
### Metrics:
|
|
|
|
- http_response
|
|
- tags:
|
|
- server (target URL)
|
|
- method (request method)
|
|
- status_code (response status code)
|
|
- result ([see below](#result--result_code))
|
|
- fields:
|
|
- response_time (float, seconds)
|
|
- response_string_match (int, 0 = mismatch / body read error, 1 = match)
|
|
- http_response_code (int, response status code)
|
|
- result_type (string, deprecated in 1.6: use `result` tag and `result_code` field)
|
|
- result_code (int, [see below](#result--result_code))
|
|
|
|
#### `result` / `result_code`
|
|
|
|
Upon finishing polling the target server, the plugin registers the result of the operation in the `result` tag, and adds a numeric field called `result_code` corresponding with that tag value.
|
|
|
|
This tag is used to expose network and plugin errors. HTTP errors are considered a successful connection.
|
|
|
|
|Tag value |Corresponding field value|Description|
|
|
--------------------------|-------------------------|-----------|
|
|
|success | 0 |The HTTP request completed, even if the HTTP code represents an error|
|
|
|response_string_mismatch | 1 |The option `response_string_match` was used, and the body of the response didn't match the regex. HTTP errors with content in their body (like 4xx, 5xx) will trigger this error|
|
|
|body_read_error | 2 |The option `response_string_match` was used, but the plugin wans't able to read the body of the response. Responses with empty bodies (like 3xx, HEAD, etc) will trigger this error|
|
|
|connection_failed | 3 |Catch all for any network error not specifically handled by the plugin|
|
|
|timeout | 4 |The plugin timed out while awaiting the HTTP connection to complete|
|
|
|dns_error | 5 |There was a DNS error while attempting to connect to the host|
|
|
|
|
|
|
### Example Output:
|
|
|
|
```
|
|
http_response,method=GET,server=http://www.github.com,status_code=200,result=success http_response_code=200i,response_time=6.223266528,result_type="success",result_code=0i 1459419354977857955
