Issue/Introduction

This article describes how to deploy the noisy-neighbor-nozzle, step-by-step, in order to identify the top log producers.

Environment

Product Version: 2.5

Resolution

1. Create a client to be used for the noisy-neighbor-nozzle:

jump-user@linux-jump-box-1804:~$ uaac target uaa.your_TAS_system_domain --skip-ssl-validation
Unknown key: Max-Age = 86400
 
Target: https://uaa.your_TAS_system_domain
 
jump-user@linux-jump-box-1804:~$ uaac token client get admin -s your_admin_client_secret
Unknown key: Max-Age = 86400
 
Successfully fetched token via client credentials grant.
Target: https://uaa.your_TAS_system_domain
Context: admin, from client admin
jump-user@linux-jump-box-1804:~$ uaac client add my-firehose-nozzle     --access_token_validity 1209600     --authorized_grant_types client_credentials,refresh_token     -s my-secret     --scope openid,oauth.approvals,doppler.firehose     --authorities oauth.login,doppler.firehose,uaa.resource
  scope: openid oauth.approvals doppler.firehose
  client_id: my-firehose-nozzle
  resource_ids: none
  authorized_grant_types: refresh_token client_credentials
  autoapprove:
  access_token_validity: 1209600
  authorities: oauth.login doppler.firehose
  name: my-firehose-nozzle
  required_user_groups:
  lastmodified: 1620983749000
  id: my-firehose-nozzle

2. Install the noisy-neighbor-nozzle app:

jump-user@linux-jump-box-1804:~$ wget https://github.com/cloudfoundry/noisy-neighbor-nozzle/releases/download/v1.5.1/noisy-neighbor.tgz
