Queue Metrics API - inconsistent response times

NICE CXone API & Integrations

Okay, so the queue metrics endpoint - the one used to get queue metrics - is returning data, but the response time is all over the place. Sometimes it’s 200ms, sometimes it’s 3+ seconds. It’s not a network thing, we’ve checked. The whole point of polling this endpoint is to get a consistent view of the queue state for our widget.

Here’s what we’ve tried:

  • We’re on Genesys Cloud, obviously.
  • Using the platform API v2.
  • SvelteKit server route doing the fetching.
  • Polling every 30 seconds - because anything faster hits rate limits.
  • OAuth proxy pattern for token management - so it’s not a token issue.
  • Queue ID is valid, confirmed.
  • The endpoint always returns 200 OK.
  • We’re not changing anything in the Architect flows.

From what I’ve seen, the API should be more predictable, right? +1 if anyone’s dealt with this before. It feels like something is happening on the Genesys Cloud side, but the logs aren’t showing anything useful.

// Example Java SDK code snippet
import com.genesys.cloud.client.ApiException;
import com.genesys.cloud.client.api.AnalyticsApi;
import com.genesys.cloud.client.model.QueueMetrics;
import com.genesys.cloud.client.ApiClient;

public class QueueMetricsPolling {

 public static void main(String[] args) {
 // Replace with your Genesys Cloud region
 String region = "us-east-1";

 // Replace with your API client credentials
 ApiClient apiClient = new ApiClient();
 apiClient.setBasePath("https://" + region + ".api.genesyscloud.com");
 apiClient.setAccessToken("YOUR_ACCESS_TOKEN"); // Or use OAuth flow

 AnalyticsApi analyticsApi = new AnalyticsApi(apiClient);

 String queueId = "YOUR_QUEUE_ID";

 try {
 QueueMetrics metrics = analyticsApi.getQueueMetrics(queueId, null, null, null, null);
 // Process the metrics data
 System.out.println(metrics);
 } catch (ApiException e) {
 System.err.println("Error fetching queue metrics: " + e.getCode());
 e.printStackTrace();
 }
 }
}

hey! sorry if this is kinda dumb, but have you tried setting a specific timeUnit parameter in the getQueueMetrics call? From what I’ve seen, the response time can vary a lot if you’re just hitting the endpoint without specifying how you want the metrics aggregated.

The API docs mention that you can specify timeUnit as seconds, minutes, hours, or days. We’ve found that using minutes or hours gives us more consistent response times, since it reduces the amount of data that needs to be processed.

Also - and this is probably really obvious - are you caching the response at all? It might help to cache the metrics for a short period of time (like 30 seconds) to reduce the number of API calls you’re making. I’m kinda new to this, so I’m not sure if that’s best practice, but it could be worth a shot?

Oh and another thing - are you hitting any API rate limits? You can check the x-rate-limit headers in the response. If you’re getting throttled, that could explain the inconsistent response times. I always forget to check those.

sorry for the newbie question, but have you checked the interval for the metrics aggregation? We have seen that the default is not very consistent.

{
 "action": "get_queue_metrics",
 "queueId": "{{intent.slots.queueId}}",
 "interval": "60" 
}

it might help to increase this value. We are using 60 seconds.
