Prometheus endpoint

[chengyak]

I follow the steps in https://www.the-guild.dev/graphql/mesh/docs/plugins/prometheus to install the lib and add the default configuration like the example in that page to my .meshrc.yml, I can build and start the service without any error, but when i try to access http://localhost:port/metrics, I got "Cannot GET /metrics". Am I using the right URL or missed something?
this is what I added

plugins:
  - prometheus:
    requestCount: true
    requestSummary: true
    parse: true
    validate: true
    contextBuilding: true
    execute: true
    errors: true
    resolvers: true
    resolversWhiteList:
      - Mutation.*
      - Query.*

#4651
With the latest release /metrics is available :)

@ardatan , thanks for your reply, I update plugin-prometheus to 0.2.0 and added the endpoint setting. but still didn't see the metrics endpoint.

here is my settings:

plugins:
  - prometheus:
    requestCount: true
    requestSummary: true
    parse: true
    validate: true
    contextBuilding: true
    execute: true
    errors: true
    resolvers: true
    resolversWhiteList:
      - Mutation.*
      - Query.*
    deprecatedFields: true
    endpoint: /metrics

and here is my packages:

"dependencies": {
    "@aws-sdk/client-secrets-manager": "^3.56.0",
    "@envelop/core": "^2.6.0",
    "@envelop/generic-auth": "^4.6.0",
    "@graphql-mesh/cli": "0.72.1",
    "@graphql-mesh/graphql": "0.27.1",
    "@graphql-mesh/openapi": "0.26.1",
    "@graphql-mesh/plugin-prometheus": "^0.2.0",
    "@graphql-mesh/runtime": "^0.36.1",
    "@graphql-mesh/transform-filter-schema": "0.14.62",
    "express": "^4.17.2",
    "graphql": "16.5.0",
    "prom-client": "^14.1.0"
  },

Make sure the indentation is correct and do you use a different HTTP server impl or Mesh's?

plugins:
  - prometheus:
     # Make sure indentation is correct
      requestCount: true
      requestSummary: true
      parse: true
      validate: true
      contextBuilding: true
      execute: true
      errors: true
      resolvers: true
      resolversWhiteList:
        - Mutation.*
        - Query.*
      deprecatedFields: true
      endpoint: /metrics

@ardatan , I am using Mesh's default http server, I didn't add and custom server. The "plugins" is in the same level as "sources", right? not inside each source, right? this is all I have in my meshrc file:

sources:
  - name: VAT_USER_DS
    handler:
      graphql:
        endpoint: "{env.VAT_USER_DS_URL}"
        schemaHeaders:
          Authorization: "{env.VAT_USER_DS_TOKEN}"
        operationHeaders:
          Authorization: "{context.headers['authorization']}"
  - name: VAT_Reporting_DS
    handler:
      openapi:
        source: "{env.VAT_Reporting_DS_SCHEMA_URL}"
        baseUrl: "{env.VAT_Reporting_DS_URL}"
        operationHeaders:
          Authorization: "{context.headers['authorization']}"

plugins:
  - prometheus:
    requestCount: true
    requestSummary: true
    parse: true
    validate: true
    contextBuilding: true
    execute: true
    errors: true
    deprecatedFields: true
    endpoint: /metrics

serve:
  port: 8888
  playground: true

The GraphQL park works ok, just 'localhost:8888/metrics' doesn't work for me

@chengyak Make sure all of your packages are latest and please fix the indentation :)

  - prometheus: # HERE!!!!
      requestCount: true
      requestSummary: true
      parse: true
      validate: true
      contextBuilding: true
      execute: true
      errors: true
      deprecatedFields: true
      endpoint: /metrics

@ardatan I think the problem is the version, updating the plugin-prometheus to 0.2.0 is not enough, I also update the mesh cli (i think it also update the runtime) and now it is working,
For the yaml file indentation, I don't think I need that extra space since it is a array properties.
Thanks a lot for the help! very cool plugin!
