NCD local gateway simulator

Local gateway simulator to stress test NCD.

Available as Docker image instedd/lgwsim

Usage

Create executable by running:

shards build --release

Run:

bin/lgwsim

Usage with InSTEDD cloud

You need to create a QST server channel in order to use this application. The easiest way is to simulate a lgw registration.

  1. Get a 4-digit registration code
$ curl -d "address=12341234" https://nuntium-stg.instedd.org/tickets.json
{"code":"5244","secret_key":"32a2a8ed-****-****-****-************","status":"pending","data":{"address":"12341234"}}

  1. Create a QST server (local gateway) from an InSTEDD Application

  2. Enter the 4-digit registration code: 5244

  3. Get the generated

$ curl "https://nuntium-stg.instedd.org/tickets/5244.json?secret_key="32a2a8ed-****-****-****-************""
{"code":"5244","secret_key":"32a2a8ed-****-****-****-************","status":"complete","data":{"address":"12341234","channel":"my_qst_simulator","account":"manas","password":"Ji******","message":null}}
  1. Lauch a QST Simulator with the above configuration
$ docker run --rm -it -e HOST=nuntium-stg.instedd.org -e ACCOUNT=manas -e CHANNEL_NAME=my_qst_simulator -e CHANNEL_PASSWORD=Ji****** instedd/lgwsim
  1. Start sending messages from the InSTEDD Application

Example using variables: docker run --rm -it -e HOST=nuntium-stg.instedd.org -e [email protected] -e CHANNEL_NAME=my_channel -e CHANNEL_PASSWORD=password -e DELAY_REPLY_MIN_SECONDS=20 -e DELAY_REPLY_MAX_SECONDS=25 -e DELAY_REPLY_PERCENT=1 instedd/lgwsim

Usage in you local environment

If you are running Nuntium in your local environment, follow the steps above to create a QST server. Your config.yml should probably have these two parameters as follows:

host: web.nuntium.lvh.me port: 80

Behaviour

For each message received, if a reply is sent, it will be according to de following rules

| Input | Reply | |-|-| | #oneof:A,B,C | A or B or C | | #numeric:N-M | a number between N and M |

For creating questionnaire steps these rules should be in the SMS message, make sure the responses are configured accordingly

The following environment variables controls other aspects of the behavior

| Variable | Default | Description | |-|-|-| | SLEEP_SECONDS | 10 | How much time to wait between fetches from the QST server (Nuntium will mark the channel as down if it's not polled every 2 minutes) | | NO_REPLY_PERCENT | 0.2 | Percent of respondents that never reply | | DELAY_REPLY_PERCENT | 0.2 | Percent of respondents that have a delay in their reply | | DELAY_REPLY_MIN_SECONDS | 0 | Of the above, minimum time in seconds of that delay (min..max) | | DELAY_REPLY_MAX_SECONDS | 60 | Of the above, maximum time in seconds of that delay (min..max) | | INCORRECT_REPLY_PERCENT | 0.2 | Percent of respondents that reply an incorrect answer | | STICKY_RESPONDENTS | true | If true, once a respondent replies, it will always reply | | INCOMING_BATCH_SIZE | 100 | How many incoming messages to fetch at once |
