SevOne Adapter

This adapter is used to integrate the Itential Automation Platform (IAP) with the SevOne System. The API for SevOne is available at [your SevOne server URL]/api/docs. The adapter utilizes the SevOne API to provide the integrations that are deemed pertinent to IAP. This ReadMe file is intended to provide information on this adapter.

Note: It is possible that some integrations will be supported through the SevOne adapter while other integrations will not.

Itential provides information on all of its product adapters in the Customer Knowledge Base. Information in the Customer Knowledge Base is consistently maintained and goes through documentation reviews. As a result, it should be the first place to go for information.

For custom built adapters, it is a starting point to understand what you have built, provide the information for you to be able to update the adapter, and assist you with deploying the adapter into IAP.


Itential Product adapters utilize SemVer for versioning. The current version of the adapter can be found in the package.json file or viewed in the IAP GUI on the System page. For Open Source Adapters, the versions available can be found in the Itential OpenSource Repository.

Release History

Any release prior to 1.0.0 is a pre-release. Initial builds of adapters are generally set up as pre-releases as there is often work that needs to be done to configure the adapter and make sure the authentication process to SevOne works appropriately.

Release notes can be viewed in or in the Customer Knowledge Base for Itential adapters.

Getting Started

These instructions will help you get a copy of the project on your local machine for development and testing. Reading this section is also helpful for deployments as it provides you with pertinent information on prerequisites and properties.

Environment Prerequisites

The following is a list of required packages for an adapter.

Connection Properties

These base properties are used to connect to SevOne upon the adapter initially coming up. It is important to set these properties appropriately.

Property Description
host Required. A fully qualified domain name or IP address.
port Required. Used to connect to the server.
base_path Optional. Used to define part of a path that is consistent for all or most endpoints. It makes the URIs easier to use and maintain but can be overridden on individual calls. An example base_path might be /rest/api. Default is ``.
version Optional. Used to set a global version for action endpoints. This makes it faster to update the adapter when endpoints change. As with the base-path, version can be overridden on individual endpoints. Default is ``.
cache_location Optional. Used to define where the adapter cache is located. The cache is used to maintain an entity list to improve performance. Storage locally is lost when the adapter is restarted. Storage in Redis is preserved upon adapter restart. Default is none which means no caching of the entity list.
stub Optional. Indicates whether the stub should run instead of making calls to SevOne (very useful during basic testing). Default is false (which means connect to SevOne).
protocol Optional. Notifies the adapter whether to use HTTP or HTTPS. Default is HTTP.

A connectivity check tells IAP the adapter has loaded successfully.

Authentication Properties

The following properties are used to define the authentication process to SevOne.

Note: Depending on the method that is used to authenticate with SevOne, you may not need to set all of the authentication properties.

Property Description
auth_method Required. Used to define the type of authentication currently supported. Authentication methods currently supported are: basic user_password, static_token, request_token, and no_authentication.
username Used to authenticate with SevOne on every request or when pulling a token that will be used in subsequent requests.
password Used to authenticate with SevOne on every request or when pulling a token that will be used in subsequent requests.
auth_field Defines the request field the authentication (e.g., token are basic auth credentials) needs to be placed in order for the calls to work.
auth_field_format Defines the format of the auth_field. See examples below. Items enclosed in {} inform the adapter to perofrm an action prior to sending the data. It may be to replace the item with a value or it may be to encode the item.
token Defines a static token that can be used on all requests. Only used with static_token as an authentication method (auth_method).
invalid_token_error Defines the HTTP error that is received when the token is invalid. Notifies the adapter to pull a new token and retry the request. Default is 401.
token_timeout Defines how long a token is valid. Measured in milliseconds. Once a dynamic token is no longer valid, the adapter has to pull a new token. If the token_timeout is set to -1, the adapter will pull a token on every request to SevOne. If the timeout_token is 0, the adapter will use the expiration from the token response to determine when the token is no longer valid.
token_cache Used to determine where the token should be stored (local memory or in Redis).

Examples of authentication field format

"Token {token}",
"Basic {b64}{username}:{password}{/b64}"

Healthcheck Properties

The healthcheck properties defines the API that runs the healthcheck to tell the adapter that it can reach SevOne. There are currently three types of healthchecks.

  • None - Not recommended. Adapter will not run a healthcheck. Consequently, unable to determine before making a request if the adapter can reach SevOne.
  • Startup - Adapter will check for connectivity when the adapter initially comes up, but it will not check afterwards.
  • Intermittent - Adapter will check connectivity to SevOne at a frequency defined in the frequency property.
Property Description
type Required. The type of health check to run.
frequency Required if intermittent. Defines how often the health check should run. Measured in milliseconds. Default is 300000.

Request Properties

The request section defines properties to help handle requests.

Property Description
number_retries Tells the adapter how many times to retry a request that has either aborted or reached a limit error before giving up and returning an error.
limit_retry_error Optional. Indicates the http error status number to define that no capacity was available and, after waiting a short interval, the adapter can retry the request. Default is 0.
failover_codes An array of error codes for which the adapter will send back a failover flag to IAP so that the Platform can attempt the action in another adapter.
attempt_timeout Optional. Tells how long the adapter should wait before aborting the attempt. On abort, the adapter will do one of two things: 1) return the error; or 2) if healthcheck_on_timeout is set to true, it will abort the request and run a Healthcheck until it re-establishes connectivity to SevOne, and then will re-attempt the request that aborted. Default is 5000 milliseconds.
healthcheck_on_timeout Required. Defines if the adapter should run a health check on timeout. If set to true, the adapter will abort the request and run a health check until it re-establishes connectivity and then it will re-attempt the request.
archiving Optional flag. Default is false. It archives the request, the results and the various times (wait time, SevOne time and overall time) in the adapterid_results collection in MongoDB. Although archiving might be desirable, be sure to develop a strategy before enabling this capability. Consider how much to archive and what strategy to use for cleaning up the collection in the database so that it does not become too large, especially if the responses are large.

SSL Properties

The SSL section defines the properties utilized for ssl authentication with SevOne. SSL can work two different ways: set the accept\_invalid\_certs flag to true (only recommended for lab environments), or provide a ca\_file.

Property Description
enabled If SSL is required, set to true.
accept_invalid_certs Defines if the adapter should accept invalid certificates (only recommended for lab environments). Required if SSL is enabled. Default is false.
ca_file Defines the path name to the CA file used for SSL. If SSL is enabled and the accept invalid certifications is false, then ca_file is required.
secure_protocol Defines the protocol (e.g., SSLv3_method) to use on the SSL request.
ciphers Required if SSL enabled. Specifies a list of SSL ciphers to use.
ecdhCurve During testing on some Node 8 environments, you need to set ecdhCurve to auto. If you do not, you will receive PROTO errors when attempting the calls. This is the only usage of this property and to our knowledge it only impacts Node 8 and 9.

Throttle Properties

The throttle section is used when requests to SevOne must be queued (throttled). All of the properties in this section are optional.

Property Description
throttle_enabled Default is false. Defines if the adapter should use throttling o rnot.
number_pronghorns Default is 1. Defines if throttling is done in a single Itential instance or whether requests are being throttled across multiple Itential instances (minimum = 1, maximum = 20). Throttling in a single Itential instance uses an in-memory queue so there is less overhead. Throttling across multiple Itential instances requires placing the request and queue information into a shared resource (e.g. database) so that each instance can determine what is running and what is next to run. Throttling across multiple instances requires additional I/O overhead.
sync-async This property is not used at the current time (it is for future expansion of the throttling engine).
max_in_queue Represents the maximum number of requests the adapter should allow into the queue before rejecting requests (minimum = 1, maximum = 5000). This is not a limit on what the adapter can handle but more about timely responses to requests. The default is currently 1000.
concurrent_max Defines the number of requests the adapter can send to SevOne at one time (minimum = 1, maximum = 1000). The default is 1 meaning each request must be sent to SevOne in a serial manner.
expire_timeout Default is 0. Defines a graceful timeout of the request session. After a request has completed, the adapter will wait additional time prior to sending the next request. Measured in milliseconds (minimum = 0, maximum = 60000).
average_runtime Represents the approximate average of how long it takes SevOne to handle each request. Measured in milliseconds (minimum = 50, maximum = 60000). Default is 200. This metric has performance implications. If the runtime number is set too low, it puts extra burden on the CPU and memory as the requests will continually try to run. If the runtime number is set too high, requests may wait longer than they need to before running. The number does not need to be exact but your throttling strategy depends heavily on this number being within reason. If averages range from 50 to 250 milliseconds you might pick an average run-time somewhere in the middle so that when SevOne performance is exceptional you might run a little slower than you might like, but when it is poor you still run efficiently.

Proxy Properties

The proxy section defines the properties to utilize when SevOne is behind a proxy server.

Property Description
enabled Required. Default is false. If SevOne is behind a proxy server, set enabled flag to true.
host Host information for the proxy server. Required if enabled is true.
port Port information for the proxy server. Required if enabled is true.
protocol The protocol (i.e., http, https, etc.) used to connect to the proxy. Default is http.

Testing an Itential Product Adapter

Mocha is generally used to test all Itential Product Adapters. There are unit tests as well as integration tests performed. Integration tests can generally be run as standalone using mock data and running the adapter in stub mode, or as integrated. When running integrated, every effort is made to prevent environmental failures, however there is still a possibility.

Unit Testing

Unit Testing includes testing basic adapter functionality as well as error conditions that are triggered in the adapter prior to any integration. There are two ways to run unit tests. The prefered method is to use the testRunner script; however, both methods are provided here.

node utils/testRunner --unit
npm run test:unit

To add new unit tests, edit the test/unit/adapterTestUnit.js file. The tests that are already in this file should provide guidance for adding additional tests.

Integration Testing - Standalone

Standalone Integration Testing requires mock data to be provided with the entities. If this data is not provided, standalone integration testing will fail. When the adapter is set to run in stub mode (setting the stub property to true), the adapter will run through its code up to the point of making the request. It will then retrieve the mock data and return that as if it had received that data as the response from SevOne. It will then translate the data so that the adapter can return the expected response to the rest of the Itential software. Standalone is the default integration test.

Similar to unit testing, there are two ways to run integration tests. Using the testRunner script is better because it prevents you from having to edit the test script; it will also resets information after testing is complete so that credentials are not saved in the file.

node utils/testRunner
  answer no at the first prompt
npm run test:integration

To add new integration tests, edit the test/integration/adapterTestIntegration.js file. The tests that are already in this file should provide guidance for adding additional tests.

Integration Testing

Integration Testing requires connectivity to SevOne. By using the testRunner script it prevents you from having to edit the integration test. It also resets the integration test after the test is complete so that credentials are not saved in the file.

Note: These tests have been written as a best effort to make them work in most environments. However, the Adapter Builder often does not have the necessary information that is required to set up valid integration tests. For example, the order of the requests can be very important and data is often required for creates and updates. Hence, integration tests may have to be enhanced before they will work (integrate) with SevOne. Even after tests have been set up properly, it is possible there are environmental constraints that could result in test failures. Some examples of possible environmental issues are customizations that have been made within SevOne which change order dependencies or required data.

node utils/testRunner
answer yes at the first prompt
answer all other questions on connectivity and credentials

Test should also be written to clean up after themselves. However, it is important to understand that in some cases this may not be possible. In addition, whenever exceptions occur, test execution may be stopped, which will prevent cleanup actions from running. It is recommended that tests be utilized in dev and test labs only.

Reminder: Do not check in code with actual credentials to systems.

Installing an Itential Product Adapter

  1. Set up the name space location in your IAP node_modules.
cd /opt/pronghorn/current/node_modules
if the @itentialopensource directory does not exist, create it:
   mkdir @itentialopensource
  1. Clone the adapter into your IAP environment.
cd \@itentialopensource
git clone\@itentialopensource/adapters/adapter-sevone
  1. Install the dependencies for the adapter.
cd adapter-sevone
npm install
  1. Add the adapter properties for SevOne (created from Adapter Builder) to the properties.json file for your Itential build. You will need to change the credentials and possibly the host information below. SevOne sample properties

  2. Restart IAP

systemctl restart pronghorn

Installing a Custom Adapter

If you built this as a custom adapter through the Adapter Builder, it is recommended you go through setting up a development environment and testing the adapter before installing it. There is often configuration and authentication work that is required before the adapter will work in IAP.

  1. Move the adapter into the IAP node_modules directory.
Depending on where your code is located, this process is different.
    Could be a tar, move, untar
    Could be a git clone of a repository
    Could also be a cp -R from a coding directory
Adapter should be placed into: /opt/pronghorn/current/node_modules/\@itentialopensource
  1. Follow Steps 3-5 (above) to install an Itential adapter to load your properties, dependencies and restart IAP.

Using this Adapter

The adapter.js file contains the calls the adapter makes available to the rest of the Itential Platform. The API detailed for these calls should be available through JSDOC. The following is a brief summary of the calls.

Generic Adapter Calls

The connect call is run when the Adapter is first loaded by he Itential Platform. It validates the properties have been provided correctly.
Insures that the adapter can communicate with SevOne. The actual call that is used is defined in the adapter properties.
Provides the adapter the ability to accept property changes without having to restart the adapter.
encryptProperty(property, technique, callback)
Will take the provided property and technique, and return the property encrypted with the technique. This allows the property to be used in the adapterProps section for the credential password so that the password does not have to be in clear text. The adapter will decrypt the property as needed for communications with SevOne.
Will return the requests that are waiting in the queue if throttling is enabled.
addEntityCache(entityType, entities, key, callback)
Will take the entities and add the list to the entity cache to expedite performance.
capabilityResults(results, callback)
Will take the results from a verifyCompatibility and put them in the format to be passed back to the Itential Platform.
hasEntity(entityType, entityId, callback)
Verifies the adapter has the specific entity.
verifyCapability(entityType, actionType, entityId, callback)
Verifies the adapter can perform the provided action on the specific entity.
Call to update the entity cache.

Specific Adapter Calls

Specific adapter calls are built based on the API of the SevOne. The Adapter Builder creates the proper method comments for generating JS-DOC for the adapter. This is the best way to get information on the calls.

Troubleshooting the Adapter

Connectivity Issues

  1. Verify the adapter properties are set up correctly.
Go into the Itential Platform GUI and verify/update the properties
  1. Verify there is connectivity between the Itential Platform Server and SevOne Server.
ping the ip address of SevOne server
try telnet to the ip address port of SevOne
  1. Verify the credentials provided for SevOne.
login to SevOne using the provided credentials
  1. Verify the API of the call utilized for SevOne Healthcheck.
Go into the Itential Platform GUI and verify/update the properties

Functional Issues

Adapter logs are located in /var/log/pronghorn. In older releases of the Itential Platform, there is a pronghorn.log file which contains logs for all of the Itential Platform. In newer versions, adapters are logging into their own files.
