This input plugin checks HTTP/HTTPS connections.
# HTTP/HTTPS request given an address a method and a timeout
[[inputs.http_response]]
## Server address (default http://localhost)
# address = "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"
- http_response
- tags:
- server (target URL)
- method (request method)
- status_code (response status code)
- result (see below)
- 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 andresult_code
field) - result_code (int, see below)
- tags:
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 |
