Unable to process clotho Kafka topics

[bnesbitt]

We're seeing a flood of issues on our development instance and we've had no luck to this point pinpointing exactly what the cause is.  We just updated to Utah Patch 1 but were seeing this while on Tokyo.  Any ideas on how to suppress this?

Hi @bnesbitt ,

You can try to troubleshoot the issue:

1. Check the Hermes status: The error message indicates that the Hermes status may be disabled or unavailable. Check the Hermes instance in the instance where you are seeing this error to ensure that it is enabled and available.

2. Check the Kafka configuration: Verify that the Kafka configuration is correct and that the instance is able to connect to the Kafka cluster.

3. Restart the Clotho service: Try restarting the Clotho service to see if that resolves the issue. If the issue persists, you may need to perform further troubleshooting or reach out to ServiceNow support for assistance.

4. Check for any recent changes: If the issue started happening after an update or a change was made, check for any recent changes to the instance or the configuration that could have caused the issue.

If my response helps you to resolve the issue close the question by ✅Accepting solution and hit 👍thumb icon. From Correct answers others will get benefited in future.

Hi @Ratnakar7 ,

Thank you for the suggestions.

1. We have Hermes installed but it is not configured at the moment.
2. We currently are not utilizing a kafka cluster and have not performed any setup to connect to one.
3. We do have MetricBase installed but we're not using it currently.  I've checked the configuration it the clotho service looks to be inactive.

At this point, we've terminated any scheduled jobs, business rules, etc that may pertain to Clotho or MetricBase.  We've also deleted the demo data that was installed with MetricBase.  We also tried repairing the MetricBase plugin with no success.

I'll put in a request for ServiceNow support to assist.

Thanks,
bnesbitt

Morning! Did you ever hear back on this? We are also getting these errors (Utah Patch 2). We don't use MetricBase but we do have the main plugin for it as part of the Application Insights app. We're also planning to put in a ticket.

What is Hermes? What is Kafka configuration? What is Clotho?
