Monitoring Auxiliary PDF Service

To monitor auxiliary services within the UI, visit the Auxiliary services page.

Auxiliary services can also be monitoring through the servicesMetadata GraphQL query:

Raw
graphql
query {
  servicesMetadata {
    name,
    serviceType,
    endpointUrl,
    healthStatus {status,message}
  }
}
Mac OS or Linux (curl)
shell
curl -v -X POST $YOUR_LOGSCALE_URL/graphql \
    -H "Authorization: Bearer $TOKEN" \

This will output a list of the configured services:

json

  "data": {
    "servicesMetadata": [
      {
        "name": "default-pdf-render-service",
        "serviceType": "pdf-render-service",
        "endpointUrl": "http://pdf-render.local:5123",
        "healthStatus": {
          "status": "OK",
          "message": "HttpEntity.Strict(text/html; charset=UTF-8,2 bytes total)"
        }
      }
    ]
