Synthetics REST API

To view a list of all the monitors in your New Relic account, send a GET request to $API_ENDPOINT/v3/monitors. For example:

curl -v \
     -H "Api-Key:$API_KEY" $API_ENDPOINT/v3/monitors

A successful request will return a 200 OK response. The data returned will be a JSON object in the following format:

{
    "monitors": [
        {
        "id": "2a1bc369-7654-489d-918e-f6g135h7i2jk",
        "name": "monitor1",
        "type": "BROWSER",
        "frequency": 60,
        "uri": "http://example.com",
        "locations": [
            "AWS_US_WEST_1"
                ],
        "status": "DISABLED",
        "slaThreshold": 7,
        "options": {},
        "modifiedAt": "2016-09-26T23:12:46.981+0000",
        "createdAt": "2016-09-26T23:12:46.981+0000",
        "userId": 0,
        "apiVersion": "0.2.2"
        }
    ],
    "count": 1
}

Query arguments:

• offset: The monitor count offset. Defaults to 0. For example, if you have 40 monitors and you use an offset value of 20, it will return monitors 21-40.
• limit: The number of results per page, maximum 100. Defaults to 50.

You can include these in your curl command as follows:

curl -v \
     -H "Api-Key:$API_KEY" $API_ENDPOINT/v3/monitors \
     -G -d 'offset=20&limit=100'

The headers include a Link to help you easily page your monitors. For example:

<https://synthetics.newrelic.com/synthetics/api/v3/monitors/?offset=0&limit=20>; rel="first", <https://synthetics.newrelic.com/synthetics/api/v3/monitors/?offset=40&limit=20>; rel="last"

To view a single synthetic monitor, send a GET request to $API_ENDPOINT/v3/monitors/$MONITOR_ID.

curl -v \
     -H "Api-Key:$API_KEY" $API_ENDPOINT/v3/monitors/$MONITOR_ID

A successful request will return a 200 OK response. The data returned will be a JSON object in the following format:

{
  "id": UUID,
  "name": string,
  "type": string,
  "frequency": integer,
  "uri": string,
  "locations": array of strings,
  "status": string,
  "slaThreshold": double,
  "userId": integer,
  "apiVersion": string
}

An invalid monitor ID will return 404 Not Found: The specified monitor doesn't exist.

To add a new monitor to your Synthetics account, send a POST request to $API_ENDPOINT/v3/monitors with a JSON payload that describes the monitor.

All fields in the following example are required unless stated otherwise:

{
"name": string [required],
"type": string (SIMPLE, BROWSER, SCRIPT_API, SCRIPT_BROWSER) [required],
"frequency": integer (minutes) [required, must be one of 1, 5, 10, 15, 30, 60, 360, 720, or 1440],
"uri": string [required for SIMPLE and BROWSER type],
"locations": array of strings [at least one required],
"status": string (ENABLED, DISABLED) [required],
"slaThreshold": double,
"options": {
  "validationString": string [only valid for SIMPLE and BROWSER types],
  "verifySSL": boolean (true, false) [only valid for SIMPLE and BROWSER types],
  "bypassHEADRequest": boolean (true, false) [only valid for SIMPLE types],
  "treatRedirectAsFailure": boolean (true, false) [only valid for SIMPLE types]
  }
}

In addition, to add the script for a scripted monitor via the REST API, call an additional API endpoint to send the script for the monitor just created. If you are using private locations with verified script execution enabled, see script locations with verified script execution.

Replace the synthetic monitoring REST API attributes in the following example with your specific values:

curl -v \
     -X POST -H "Api-Key:$API_KEY" \
     -H 'Content-Type: application/json' $API_ENDPOINT/v3/monitors \
     -d '{ "name" : "monitor1", "frequency" : 15, "uri" : "http://my-uri.com", "locations" : [ "AWS_US_WEST_1" ], "type" : "browser", "status" : "enabled", "slaThreshold" : "1.0"}'

A successful request will return a 201 Created response, with the URI of the newly-created monitor specified in the location header. Possible error codes include:

• 400 Bad Request: One or more of the monitor values is invalid, or the format of the request is invalid. For example: the frequency is out of bounds or one or more of the specified locations is invalid. (See the error message in the body of the response.)
• 402 Payment Required: Creating the monitor will increase your scheduled checks past your account's purchased check limit.

To update an existing monitor in New Relic, send a PUT request to $API_ENDPOINT/v3/monitors/$MONITOR_ID. In addition, for scripted monitors, follow the procedures to update the BASE64 encoded script.

All fields are required. However, the TYPE of the monitor cannot be changed.

Use a specific monitor ID, and replace the synthetic monitoring REST API attributes with your specific values.

curl -v \
     -X PUT -H "Api-Key:$API_KEY" \
     -H 'Content-Type: application/json' $API_ENDPOINT/v3/monitors/$MONITOR_ID \
     -d '{ "name" : "updated monitor name", "type": "monitor type", "frequency" : 15, "uri" : "http://my-uri.com/", "locations" : [ "AWS_US_WEST_1" ], "status" : "enabled", "slaThreshold": "7.0" }'

PUT requests are intended to replace target entities, so all attributes required in the JSON payload when creating a new monitor are also required when updating an existing monitor.

A successful request will return a 204 No Content response, with an empty body. Possible error codes include:

• 400 Bad Request: One or more of the monitor values is invalid, or the format of the request is invalid. For example, the frequency is out of bounds or one or more of the specified locations is invalid. (See the error message in the body of the response.)
• 404 Not Found: The specified monitor does not exist.

To patch an existing monitor in New Relic, send a PATCH request to $API_ENDPOINT/v3/monitors/$MONITOR_ID.

Use a specific monitor ID, and replace the synthetic monitoring REST API attributes with your specific values.

curl -v \
     -X PATCH -H "Api-Key:$API_KEY" \
     -H 'Content-Type: application/json' $API_ENDPOINT/v3/monitors/$MONITOR_ID \
     -d '{ "name" : "updated monitor name" }'

PATCH requests are intended to update individual attributes of your synthetic monitors rather than updating the entire entity, so you may provide only the attributes you want to update.

A successful request will return a 204 No Content response, with an empty body. Possible error codes include:

• 400 Bad Request: One or more of the monitor values is invalid, or the format of the request is invalid. For example, the frequency is out of bounds, or one or more of the specified locations is invalid. (See the error message in the body of the response.)
• 404 Not Found: The specified monitor does not exist.

To delete an existing monitor in synthetic monitoring, send a DELETE request to $API_ENDPOINT/v3/monitors/$MONITOR_ID:

curl -v \
     -H "Api-Key:$API_KEY" \
     -X DELETE $API_ENDPOINT/v3/monitors/$MONITOR_ID

A successful request will return a 204 No Content response, with an empty body. An unsuccessful request will return the response 404 Not Found: The specified monitor does not exist.

To retrieve the list of valid locations in your synthetic monitors, use the following command:

curl -v \
     -X GET -H "Api-Key:$API_KEY" $API_ENDPOINT/v1/locations

To view the script associated with a specific SCRIPT_BROWSER or SCRIPT_API in your account's synthetic monitors, send a GET request to $API_ENDPOINT/v3/monitors/$MONITOR_ID/script. For example:

curl -v
     -H "Api-Key:$API_KEY"
     $API_ENDPOINT/v3/monitors/$MONITOR_ID/script

A successful request will return a 200 OK response. The data returned will be a JSON object in the following format:

{
  "scriptText": BASE64 encoded string
}

Possible error codes include:

• 403 Forbidden: The specified monitor is not of type SCRIPT_BROWSER or SCRIPT_API.
• 404 Not Found: The specified monitor doesn't exist or the script associated with the monitor doesn't exist.

To add a new scripted monitor to your synthetic monitors with the REST API:

1. Follow standard API procedures to add a new monitor, and identify the type as a SCRIPT_BROWSER or SCRIPT_API.

2. Update the new monitor with a BASE64 encoded version of the script to the $MONITOR_UUID/script endpoint.

   For more information, refer to the example.

   If you are using private locations with verified script execution enabled, see script locations with verified script execution.

To update the script associated with a specific SCRIPT_BROWSER or SCRIPT_API monitor, send a PUT request to $API_ENDPOINT/v3/monitors/$MONITOR_ID/script with a JSON payload that contains the scriptText (required).

scriptPayload='{"scriptText":BASE64 encoded string}'


curl -v -X PUT \
     -H "Api-Key:$API_KEY" \
     -H 'Content-Type: application/json' \
     $API_ENDPOINT/v3/monitors/$MONITOR_UUID/script \
     -d $scriptPayload

If you are using private locations with verified script execution enabled, see script locations with verified script execution.

A successful request will return a 204 No Content response with an empty body. Possible error codes include:

• 400 Bad Request: Invalid BASE64 encoded string for scriptText or hmac.
• 403 Forbidden: The specified monitor is not of the type SCRIPT_BROWSER or SCRIPT_API.
• 404 Not Found: The specified monitor does not exist.

When creating or updating monitors for private locations that have verified script execution turned on, you must use scriptLocations to set the password:

{
  "scriptText": BASE64 encoded String,
  "scriptLocations": [
    {
      "name": Location name,
      "hmac" BASE64 encoded String of SHA256 HMAC for location
    }
  ]
}

The password used to generate the HMAC string must match the password set for the private location. If you have multiple locations with Verified script execution enabled each location must have the HMAC calculated. When generating the HMAC string, use the SHA256 algorithm with the script and password.

Here's an example for the script:

var assert = require('assert');
assert.equal('1', '1');

This example uses password as the password for the scriptLocation:

curl -v
    -X PUT -H "Api-Key:$API_KEY"
    -H 'content-type: application/json'
    $API_ENDPOINT}/v3/monitors/$MONITOR_ID/script
    -d '{ "scriptText": "dmFyIGFzc2VydCA9IHJlcXVpcmUoJ2Fzc2VydCcpOw0KYXNzZXJ0LmVxdWFsKCcxJywgJzEnKTs=","scriptLocations": [ { "name": "my_vse_enabled_location", "hmac": "MjhiNGE4MjVlMDE1N2M4NDQ4MjNjNDFkZDEyYTRjMmUzZDE3NGJlNjU0MWFmOTJlMzNiODExOGU2ZjhkZTY4ZQ=="} ]}'

Calculation steps:

1. Calculate the HMAC value from the script. One way is to use: cat script | openssl dgst -sha256 -hmac "password" > hmac
2. Remove the newline character if one was added by openssl.
3. Encode the HMAC in BASE64 without line breaks.

The following example shows curl commands to create a scripted browser monitor.

• At the top of the script, replace the variables with your specific values.

• For the scriptfile variable, identify the filename for the script to be created. Here is a sample script that can be saved as sample_synth_script.js to use in the example:

  var assert = require("assert");
  $browser.get("http://example.com").then(function(){
    // Check the H1 title matches "Example Domain"
    return $browser.findElement($driver.By.css("h1")).then(function(element){
      return element.getText().then(function(text){
        assert.equal("Example Domain", text, "Page H1 title did not match");
      });
    });
  }).then(function(){
    // Check that the external link matches "http://www.iana.org/domains/example"
    return $browser.findElement($driver.By.css("div > p > a")).then(function(element){
      return element.getAttribute("href").then(function(link){
        assert.equal("http://www.iana.org/domains/example", link, "More information link did not match");
      });
    });
  });
