Hey @tkale - Emoji’s aren’t sent as default attributes by any agent to New Relic - That said we do support adding emojis as custom attributes.
For testing the health of your services, you may need to do some in application testing, to determine which emoji to send New Relic at any time.
For example, the below is some pseudo-code that may help;
if(responseTime < 1.5 seconds)
newrelic.sendCustomAttributes('System Status', '🙂');
else if (responseTime > 1.5 seconds AND responseTime < 3 seconds)
newrelic.sendCustomAttributes('System Status', '😐');
newrelic.sendCustomAttributes('System Status', '😢');
Note that this is not a tested chunk of code, the functions involved in sending custom attributes depends completely on where you’re sending them from. See the docs here on how to do so from your applications: Sending Custom Data to Insights
You can see examples on using the Insert API, and of Emoji’s in Insights over here: Relic Solution: Custom Events & Custom Attributes
