Merging event with patch will result in valid VES event. Template itself should be a correct VES event as well as valid json object. -In order to apply custom template, just copy it to ./templates directory. -*notification.json* and *registration.json* are available by default in *./templates* directory. - -#### Template management -The simulator provides means for managing templates. Supported actions: adding, editing (overriding) and deleting are available via HTTP endpoint */template* - -```GET /template/list``` -Lists all templates known to the simulator. - -```GET /template/get-content/{name}``` -Gets template content based on *name* path variable. - -```POST /template/upload?override=true``` -Saves template content under *name* path variable. The non-mandatory parameter *override* allows overwriting an existing template. - -Sample payload: -``` -{ - "name": "someTemplate", - "template": { - "commonEventHeader": { - "domain": "notification", - "eventName": "vFirewallBroadcastPackets" - }, - "notificationFields": { - "arrayOfNamedHashMap": [{ - "name": "A20161221.1031-1041.bin.gz", - "hashMap": { - "fileformatType": "org.3GPP.32.435#measCollec" - } - }] - } - } -} -``` - -### Searching for key-value conditions in stored templates -Simulator allows to search through stored templates and retrieve names of those that satisfy given criteria passed in form of key-value pairs (See examples below). -Following data types are supported in search as values: --integer --string --double --boolean -Searching for null values as well as incorporating regex expression with intention to find a match is not supported. -Search expression must be valid JSON, thus no duplicate keys are allowed - user could specify the same parameter multiple times, but only last occurrence will be applied to query. -Example search expression: - -{"domain": "notification", "sequence": 1, "startEpochMicrosec": 1531616794, "sampleDouble": 2.5} - -will find all templates that contain all of passed key-value entries. There is an AND condition beetwen given criteria - all of them must be satisfied to qualify template as matching item. - Keys of search expressions are searched in case insensitive way as well as string values. -Where it comes to values of numerical and boolean type exact match is expected. - -API usage: - -```POST /template/search``` -Produces query that returns templates that contain searched criteria - -Sample payload: -``` -{ - "searchExpr": { - "domain": "notification", - "sequence": 1, - "startEpochMicrosec": 1531616794, - "sampleDouble": 2.5 - } -} -``` -Sample response: -``` -[notification.json] -``` - - -Note: Manually deployed templates, or actually existing ones, but modified inside the templates catalog '/app/templates', will be automatically synchronized with schemas stored inside the database. That means that a user can dynamically change the template content using vi editor at simulator container, as well as use any editor at any machine and then push the changes to the template folder. All the changes will be processed 'on the fly' and accessible via the rest API. - -### Periodic events -Simulator has ability to send event periodically. Rest API support parameters: -* repeatCount - count of times that event will be sent to VES -* repeatInterval - interval (in second) between two events. -(Checkout example to see how to use them) - -### Patching -User is able to provide patch in request, which will be merged into template. - -Warning: Patch should be a valid json object (no json primitives nor json arrays are allowed as a full body of patch). - -This mechanism allows to override part of template. -If in "patch" section there are additional parameters (absent in template), those parameters with values will be added to event. -Patching mechanism supports also keywords that enables automatic value generation of appropriate type - -### Keyword support -Simulator supports corresponding keywords: -- \#RandomInteger(start,end) - substitutes keyword with random positive integer within given range (range borders inclusive) -- \#RandomPrimitiveInteger(start,end) - the same as #RandomInteger(start,end), but returns long as result -- \#RandomInteger - substitutes keyword with random positive integer -- \#RandomString(length) - substitutes keyword with random ASCII string with specified length -- \#RandomString - substitutes keyword with random ASCII string with length of 20 characters -- \#Timestamp - substitutes keyword with current timestamp in epoch (calculated just before sending event) -- \#TimestampPrimitive - the same as \#Timestamp, but returns long as result -- \#Increment - substitutes keyword with positive integer starting from 1 - for each consecutive event, value of increment property is incremented by 1 - -Additional hints and restrictions: -All keywords without 'Primitive' in name return string as result. To specify keyword with 2 arguments e.g. #RandomInteger(start,end) no whitespaces between arguments are allowed. -Maximal value of arguments for RandomInteger is limited to the java integer range. Minimal is always 0. (Negative values are prohibited and wont be treated as a correct parts of keyword). -RandomInteger with parameters will automatically find minimal and maximal value form the given attributes so no particular order of those is expected. - -How does it work? -When user do not want to fill in parameter values that are not relevant from user perspective but are mandatory by end system, then keyword feature should be used. -In template, keyword strings are substituted in runtime with appropriate values autogenerated by simulator. -Example can be shown below: - -Example template with keywords: - - { - "event": { - "commonEventHeader": { - "eventId": "123#RandomInteger(8,8)", - "eventType": "pnfRegistration", - "startEpochMicrosec": "#Timestamp", - "vesEventListenerVersion": "7.0.1", - "lastEpochMicrosec": 1539239592379 - }, - "pnfRegistrationFields": { - "pnfRegistrationFieldsVersion":"2.0", - "serialNumber": "#RandomString(7)", - "vendorName": "Nokia", - "oamV4IpAddress": "val3", - "oamV6IpAddress": "val4" - } - } - } - -Corresponding result of keyword substitution (event that will be sent): - - { - "event": { - "commonEventHeader": { - "eventId": "1238", - "eventType": "pnfRegistration", - "startEpochMicrosec": "154046405117", - "vesEventListenerVersion": "7.0.1", - "lastEpochMicrosec": 1539239592379 - }, - "pnfRegistrationFields": { - "pnfRegistrationFieldsVersion":"2.0", - "serialNumber": "6061ZW3", - "vendorName": "Nokia", - "oamV4IpAddress": "val3", - "oamV6IpAddress": "val4" - } - } - } - - -### Logging -Every start of simulator will generate new logs that can be found in docker pnf-simualtor container under path: -/var/log/ONAP/pnfsimulator/pnfsimulator_output.log - -### Swagger -Detailed view of simulator REST API is available via Swagger UI -Swagger UI is available on *http://<simulator_ip>:5000/swagger-ui.html* - -### History -User is able to view events history. -In order to browse history, go to *http://<simulator_ip>:8081/db/pnf_simulator/eventData* - -### TLS Support -Simulator is able to communicate with VES using HTTPS protocol. -CA certificates are incorporated into simulator docker image, thus no additional actions are required from user. - -Certificates can be found in docker container under path: */usr/local/share/ca-certificates/* - -Simulator works with VES that uses both self-signed certificate (already present in keystore) and VES integrated to AAF. - - -## Developers Guide - -### Integration tests -Integration tests are located in folder 'integration'. Tests are using docker-compose from root folder. -This docker-compose has pnfsimulator image set on nexus3.onap.org:10003/onap/pnf-simulator:5.0.0-SNAPSHOT. -To test your local changes before running integration tests please build project using: - - 'mvn clean package docker:build' - -then go to 'integration' folder and run: - - 'mvn test' |
