Monitor HTTP Endpoints

With SigNoz, you can monitor the health of the HTTP endpoints and set up an alert in case of HTTP endpoint failure status codes.

  • Add the httpcheck receiver to the config and set up the collector OTLP exporter to send data to SigNoz Cloud.

    receivers:
    httpcheck:
    targets:
    - endpoint: http://example.com
    method: GET
    collection_interval: 10s
    ...
    exporters:
    otlp:
    endpoint: "ingest.{region}.signoz.cloud:443"
    tls:
    insecure: false
    headers:
    "signoz-access-token": "<SIGNOZ_INGESTION_KEY>"
    ...

    Depending on the choice of your region for the SigNoz cloud, the ingest endpoint will vary according to this table.

    RegionEndpoint
    USingest.us.signoz.cloud:443
    INingest.in.signoz.cloud:443
    EUingest.eu.signoz.cloud:443

    The HTTP Check Receiver can be used for synthetic checks against HTTP endpoints. This receiver will make a request to the specified endpoint using the configured method. This scraper generates a metric labelled for each HTTP response status class with a value of 1 if the status code matches the class.

  • Next, we will modify the pipeline to include the receiver we have enabled above.

    service:
    ....
    metrics:
    receivers: [otlp, httpcheck]
    processors: [batch]
    exporters: [otlp]
  • We can restart the otel collector container/process so that new changes are applied and see the metrics generated for synthetic checks.

  • This receiver creates a metric name httpcheck_status with value 1 if the check resulted in status_code matching the status_class, otherwise 0. For more info on the additional metrics and attributes available, please read the documentation here.

Monitoring the Health of Multiple Endpoints​

You can configure targets for the httpcheck receiver to monitor the health of one or more endpoints. Following is the sample config that monitors two endpoints.

receivers:
httpcheck:
targets:
- endpoint: http://example.com
method: GET
- endpoint: http://my-app.com
method: GET
collection_interval: 10s
...
exporters:
otlp:
endpoint: "ingest.{region}.signoz.cloud:443"
tls:
insecure: false
headers:
"signoz-access-token": "<SIGNOZ_INGESTION_KEY>"
...
service:
....
metrics:
receivers: [otlp, httpcheck]
processors: [batch]
exporters: [otlp]
