Hygieia Api

All About Hygieia API - Learn how to install and configure Hygieia API

Hygieia API layer contains all the typical REST API services that work with the source system data (collected by service tasks). The Hygieia API layer is an abstraction of the local and source system data layer. All API REST controllers are generic to their purpose - they are not specific to any given source system.

For detailed information on APIs, see the Swagger documentation available at http://[your-domain].com/api/swagger/index.html#.

Hygieia uses Spring Boot to package the API as an executable JAR file with dependencies.

Setup Instructions

• Step 1 - Artifact Preparation:

  Please review the two options in Step 1 to find the best fit for you.

  Option 1 - Download the artifact:

  You can download the SNAPSHOTs from the SNAPSHOT directory here or from the maven central repository here.

  Option 2 - Build locally:

  To configure the Hygieia API layer, git clone the api repo. Then, execute the following steps:

  To package the API source code into an executable JAR file, run the Maven build from the \api directory of your source code installation:

  mvn install

  The output file api.jar is generated in the \api\target folder.

  Once you have chosen an option in Step 1, please proceed:

• Step 2: Set Parameters in the API Properties File

  Set the configurable parameters in the api.properties section to connect to the Dashboard MongoDB database instance, including properties required by the API module. To configure the parameters, refer to the API properties section.

  For more information about the server configuration, see the Spring Boot documentation.

• Step 3: Run the API

  To run the executable file, change directory to 'api\target' and then execute the following command from the command prompt:

  java -jar api.jar --spring.config.location=C:\[path to api.properties file] -Djasypt.encryptor.password=hygieiasecret

  Verify API access from the web browser using the url: http://localhost:8080/api/ping.

  By default, the server starts at port 8080 and uses the context path \api. You can configure these values in the api.properties file for the following properties:

  server.contextPath=/api
  server.port=8080

  Note: The 'jasypt.encryptor.password' system property is used to decrypt the database password.

API Properties Section

The sample api.properties lists parameters with sample values to configure the API layer. Set the parameters based on your environment setup.

# api.properties
dbname=dashboarddb
dbusername=dashboarduser[MogoDB Database Username, defaults to empty]
dbpassword=dbpassword[MongoDB Database Password, defaults to empty]
dbhost=[Host on which MongoDB is running, defaults to localhost]
dbport=[Port on which MongoDB is listening, defaults to 27017]
dbreplicaset=[false if you are not using MongoDB replicaset]
dbhostport=[host1:port1,host2:port2,host3:port3]
server.contextPath=[Web Context path, if any]
server.port=[Web server port - default is 8080]
logRequest=false
logSplunkRequest=false
corsEnabled=false
corsWhitelist=http://domain1.com:port,http://domain2.com:port
version.number[email protected]@

auth.expirationTime=[JWT expiration time in milliseconds]
auth.secret=[Secret Key used to validate the JWT tokens]
auth.authenticationProviders=[Authentication types you would like to enable, defaults to STANDARD, ex: STANDARD,LDAP]
auth.ldapServerUrl=[LDAP Server URL, including port of your LDAP server]
auth.ldapUserDnPattern=[LDAP User Dn Pattern, where the username is replaced with '{0}']

# LDAP Server URL, including port of your LDAP server

# If using standard LDAP
# LDAP User Dn Pattern, where the username is replaced with '{0}'
auth.ldapUserDnPattern=[uid={0},OU=Users,dc=your,dc=company,dc=com]

# If using ActiveDirectory
# This will be the domain part of your userPrincipalName
auth.adDomain=[company.com]
# This will be your root dn
auth.adRootDn=[dc=your,dc=company,dc=com]
# This will be your active directory URL (required for AD)
auth.adUrl=[Need an example]

monitor.proxy.host=[hostname of proxy server]
monitor.proxy.type=[http|socks|direct]
monitor.proxy.port=[port enabled on proxy server]
monitor.proxy.username=[proxy username]
monitor.proxy.password=[proxy password]

# This will be the page size for pagination on Hygieia landing page. If this property is not set, the default value is set to 10.
pageSize=[Integer value]

# API token generated for basic authentication to secure APIs.
key=[api token]

# SSO properties with header values from UI layer
auth.userEid=[name of the header containing EID]
auth.userEmail=[name of the header containing user's email]
auth.userFirstName=[name of the header containing user's first name]
auth.userLastName=[name of the header containing user's last name]
auth.userMiddelInitials=[name of the header containing user's middle name]
auth.userDisplayName=[name of the header containing user's display name]

# Github sync api settings 

# List of not built commits
githubSyncSettings.notBuiltCommits;

# Maximum history of days to sync from current time. Default to 60 days
githubSyncSettings.firstRunHistoryDays;

# Offset time from last updated // 10 mins default
githubSyncSettings.offsetMinutes;

# Total fetch count // Default to 100
githubSyncSettings.fetchCount;

# Commits and pull sync time // Default to 86400000ms - 1 day in milliseconds
githubSyncSettings.commitPullSyncTime;

In addition to these properties, add in any additional parameters that your environment may need. We used Github sync api settings as an example, but you will customize based on your setup.

All values in the api.properties file are optional. For instance, if you have MongoDB installed with no authorization, you must be able to run the API even without the properties file.

Note the following:

• in the api.properties file, if you do not define the value of dbusername, then Hygieia skips the MongoDB authorization process.
• Specify the Expiration Time to see content on your dashboard. If you do not specify a value for Expiration Time, then the token permanently expires, and users will not be able to see any content on the dashboard. However, the application start-up is not impacted by this action.
• If you do not enter a value for the secret password, then the system generates a random key. To allow multiple instances of the API to validate the same JWT token, provide the same key for each running instance of the API.
• If you do not provide values for the LDAP parameters, then LDAP is not available as an authentication provider for your application.
• When enabling proxy support for the monitor widget, if you do not specify, then system ignores the rest of the monitor.proxy arguments. If you are using Docker, then by default, the port is 80 and the type is HTTP. When you run the application locally, you must specify the values for these properties (i.e., for the port and the type).

Docker Image for API

You can install Hygieia by using a docker image from docker hub. This section gives detailed instructions on how to download and run with Docker.

• Step 1: Download

  Navigate to the api docker hub location here and download the latest image (most recent version is preferred). Tags can also be used, if needed.

• Step 2: Run with Docker

  Docker run -e SKIP_PROPERTIES_BUILDER=true -v properties_location:/hygieia/config image_name

  • -e SKIP_PROPERTIES_BUILDER=true
    indicates whether you want to supply a properties file for the java application. If false/omitted, the script will build a properties file with default values
  • -v properties_location:/hygieia/config
    if you want to use your own properties file that located outside of docker container, supply the path here.
    • Example: -v /Home/User/Document/application.properties:/hygieia/config

Basic Authentication for Secure APIs

To carry out basic authentication for secure APIs, execute the following steps:

1. From the admin menu, generate an 'apiToken' for an 'apiUser'.

2. Create a POST request with the following two headers and make a REST call for secured API.

   • Add Authorization header

   String passwordIsAuthToken = "PasswordIsAuthToken:{\"apiKey\":\"" + <generated apitoken> + "\"}";
   byte[] encodedAuth = Base64.encodeBase64(passwordIsAuthToken.getBytes(StandardCharsets.US_ASCII));
   String authHeader = "apiToken " + new String(encodedAuth);
   Authorization: <authHeader>

   • Add apiUser header

   apiUser <apiuser>
   

Rundeck Webhook Integration

Hygieia supports registering deployments using the Rundeck webhook. In the Rundeck job configuration, select Send Notification? and check the on success and on failure webhook checkboxes. Configure the URL as http://<apihost>:<apiport>/api/deploy/rundeck. To provide configurability, a few additional features can be added to the webhook URL to locate the proper data for registering the deployment.

You can add additional request parameters to the webhook URL to provide input on locating this data. You can specify these parameters as optionName=<value> or optionNameParam=<value>. When the webhook URL provides a parameter in the form optionName=<value>, it will use the value provided in the parameter for the field in Hygieia. When the webhook URL provides a request parameter in the form optionNameParam=<value>, the option named <value> is queried and the value of that option in the job is used to populate that field. Otherwise, the default values are used.

You can add additional request parameters for the following options:

• appName
• envName (required)
• artifactName (required)
• artifactGroup
• artifactVersion
• niceName - Name that appears for the collector in Hygieia UI.

For example, to set the artifactName based on the deploymentUnit option in the Rundeck job, the webhook URL is: http://<apihost>:<apiport>/api/deploy/rundeck?artifactNameParam=deploymentUnit. To set the envName to be QA every time this job runs, the webhook URL is: http://<apihost>:<apiport>/api/deploy/rundeck?envName=QA.

If these values are not provided, the webhook first queries the job to see if it has an option that matches the name of the field. If not, it will look through the following possibilities:

• appName
  • hygieiaAppName
• envName
  • environment
  • env
  • hygieiaEnvName
• artifactName
  • artifactId
  • hygieiaArtifactName
• artfactGroup
  • group
  • hygieiaArtifactGroup
• niceName
  • hygieiaNiceName

For the required fields, if the methods to locate values is exhausted, the webhook endpoint fails and deployment is not registered. An exception appears in the Hygieia API log with the field name that is missing from the job. If appName is not set, it is set based on the Rundeck project name.

Troubleshooting Instructions

Scenario 1

The API module fails to launch with the following error:

Error creating bean with name 'dashboardRepository': Invocation of init method failed; nested exception is org.springframework.dao.DuplicateKeyException: Write failed with error code 11000 and error message 'null'

In this case, execute the following steps:

• Step 1 : Save the following lines to a file called fixdups.js:

  var dupsExist = false;
  db.dashboards.aggregate([
    { $group: {
  	_id: { firstField: "$title"},
  	uniqueIds: { $addToSet: "$_id" },
  	count: { $sum: 1 }
    }},
    { $match: {
  	count: { $gt: 1 }
    }}
  ]).forEach(
  	function(myDoc) {
  		dupsExist = true;
  		print(myDoc.count + " dashboards have the same title " + myDoc._id.firstField);
  		var arr = myDoc.uniqueIds;
  		for(i=0; i<arr.length; i++) {
  			var oneDash = db.dashboards.findOne({_id: arr[i]});
  			var newTitle = oneDash.title + "_" + oneDash.owner + "_" + i;
  			print("Rename " + oneDash.title + " to " + newTitle);
  			db.dashboards.update({_id: arr[i]},{$set:{title: newTitle}});
  		}
  	}
  );
  
  if (!dupsExist) {
  	print("No duplicate title dashboards found.");
  }
  

• Step 2 : Run the following in the command line:

  mongo <dbhost>:<dbport>/<dbname> fixdups.js

Scenario 2

The Hygieia dashboard does not show up for a specific login type you created, before introducing Auth type as 'STANDARD' or 'LDAP'.

In this case, execute the following steps:

• Step 1 : Save the following lines to a file called fixAuths.js

  var count = 0;
  db.dashboards.aggregate([{$match:{"owners.authType": {$exists : false}}}]).forEach(
  	function(myDoc) {
  		var ownerName = myDoc.owner;
  		print("Updating owner information for dashboard title --"+ myDoc.title+ "  owner name --"+myDoc.owner);
  		db.dashboards.update(
  			{ _id: myDoc._id},
  			{
  				$push: {
  					owners: {
  						$each: [{username: ownerName, authType: "STANDARD"}]
  					}
  				}
  			}
  		)
  		db.dashboards.update({_id: myDoc._id},{$unset: {owner:1}},{multi: true});
  		count++;
  	}
  );
  print(count+" dashboards updated successfully");
  

• Step 2 : Run the following in command line:

  mongo <dbhost>:<dbport>/<dbname> fixAuths.js
