Simple browser, scripted browser, and API monitors execute in the runtime environment used when the monitors were created. Your monitors won't automatically convert to newer runtimes when those runtimes release.
Monitors running on older runtimes lose out on new runtime features, so it's important that you understand which runtimes are used by your monitors.
Read on to learn how to:
- Upgrade a synthetic monitor
- View a synthetic monitor upgrade history
- Use environment variables in runtimes
- Review runtime dependencies
Ping monitors are not affected by changes in runtime versions.
To see a history of monitor version upgrades, query the
Make your scripted monitors more contextually aware by using the
$env variable properties. When the script executes, these properties represent important information about the runtime environment.
You do not need to import

$http variables. For example:
console.log('running in ' + $env.LOCATION); $browser.get('https://example.com');

Starting with the Node 16.10.0 runtime release, the API runtime will be managed separately from the browser runtime. This is also known as our next-generation runtime. This is the first scripted API runtime based on the
got module instead of the deprecated
request module. The
got module is exposed in a
request compatible format via the
The API runtime is used for these monitor types:
- Broken links monitor
- Certificate check monitors
- Scripted API monitors
If you're unsure about your monitor's runtime version, edit your monitor and check the "Runtime" drop down in the "Configure monitor" tab. You can also query the
runtimeTypeVersion attribute on
SyntheticCheck events where the
runtimeType = 'NODE_API'.
With the Chrome 100 runtime release, the [browser runtime] (/docs/synthetics/synthetic-monitoring/using-monitors/new-runtime) is managed separately from the API runtime. This is also known as our next-generation runtime.
The browser runtime is used for these monitor types:
- Scripted brower monitors
- Simple browser monitors
- Step monitors
If you're unsure about your monitor's runtime version, edit your monitor and check the "Runtime" drop down on the "Configure monitor" tab. You can also query the runtimeTypeVersion attribute on SyntheticCheck events where the runtimeType = 'CHROME_BROWSER'.
The monitor version always matches its runtime version, and determines what features the monitor can execute. The section below lists runtimes with its available features.
If you're unsure about your monitor's version, go to one.newrelic.com > Synthetics > Upgrade monitors. You won't see the Upgrade monitors option if you're already on the latest runtime version.
Here are monitor version details for all monitor types except ping:
