This project was generated with Angular CLI version 1.0.0.

Development server

Run npm start or yarn start for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.

Webpack Development Config

In order to use the UI without changing the main webpack config file (and commit accidentally) we can use a file for that. So you can set a service URL proxy.

The content of the can be:

const merge = require('webpack-merge');
const baseConfig = require('./webpack.config.js');

module.exports = merge(baseConfig, {
  devServer: {
    historyApiFallback: true,
    proxy: {
      '/api': '', // proxying the api requests
      '/login': '', // proxying the login action
      '/logout': '' // proxying the the logout action

And you can start it that way: yarn start --config

Code scaffolding

Run ng generate component component-name to generate a new component. You can also use ng generate directive/pipe/service/class/module.


Run npm run build or yarn build to build the project. The build artifacts will be stored in the dist/ directory. Use the npm run build-prod or yarn build-prod command for a production build.

Running unit tests

Run npm test or yarn test to execute the unit tests via Karma.

Running end-to-end tests

Run npm run e2e or yarn e2e to execute the end-to-end tests via Protractor. Before running the tests make sure you are serving the app via npm start or yarn start.

To get more help on the Angular CLI use ng help or go check out the Angular CLI README.

Application Info

Routing and URL params

We use Matrix URIs to route our components. That means within the components we use semicolon separated parameters. You can create/generate Log Search Client application URL with the following paths and parameters

URL pattern: /logs/{logs-type};{filter-param1};...;{filter-paramN} Where the {logs-type} can be serviceLogs or auditLogs right now.

For this screen the available URL params are the followings:

  • components:
    • type: filter parameter
    • a comma separated list of components/services
    • eg.: components=activity_explorer,ambari_agent
  • levels:
    • type: filter parameter
    • a comma separated list of log levels
  • hosts:
    • type: filter parameter
    • a comma separated list of hosts
    • eg.:,
  • query:
    • type: filter parameter
    • a JSON object with the following available keys as filters
    • eg.: [{"name": "level", "label": "Level", "value": "ERROR", "isExclude": false}]

Time range matrix params

To filter for a range of time you can use the following matrix parameters:

  • timeRangeUnit: the unit of the time
    • m: minute
    • h: hour
    • d: day
    • w: week
    • M: month
    • y: year
  • timeRangeType
    • LAST: it will count the time from the current moment back
    • PAST: it will count the time from the end of the previous time unit (set up in timeRangeUnit)
    • CURRENT: it will count the time from the end of the current time unit (set up in timeRangeUnit)
    • CUSTOM: will check the timeRangeStart and the timeRangeEnd matrix parameters
  • timeRangeStart: UTC + Time zone format, eg.: timeRangeStart=2018-06-30T22:00:00.000Z
  • timeRangeEnd: UTC + Time zone format, eg.: timeRangeStart=2018-06-30T23:00:00.000Z

Examples to defining time ranges:

Last 3 hours timeRangeType=LAST;timeRangeInterval=3;timeRangeUnit=h Last 7 days: timeRangeType=LAST;timeRangeInterval=7;timeRangeUnit=d Last 1 year timeRangeType=LAST;timeRangeInterval=1;timeRangeUnit=y Previous week timeRangeType=PAST;timeRangeUnit=w Previous month timeRangeType=PAST;timeRangeUnit=M Custom time range timeRangeType=CUSTOM;timeRangeStart=2018-07-01T10:06:00.000Z;timeRangeEnd=2018-07-02T13:06:00.000Z

The query param

The query matrix param is an array of filter params in JSON format. The item schema is the following:

    name: string,
    label: string,
    value: string/number/boolean,
    isExclude: boolean

Where the name is for the field name that you want to filter, the label is what the filter input bar will display, the value is the filter value and the isExclude is a boolean value indicating if the given field value should be included or excluded from the search result.
