Troubleshooting the “Service Is Not In Known List” Error in YACE

When YACE (Yet Another CloudWatch Exporter) reports the error “Service Is Not In Known List”, it indicates that the service name specified in the configuration is not recognized by YACE’s internal list of supported AWS services. This typically occurs because the service is either misspelled, deprecated, or not yet supported by the version of YACE you are using.

To effectively troubleshoot this issue, consider the following steps:

Verify Service Name Accuracy: Check the spelling and casing of the service name in your configuration file. AWS service names are case-sensitive and must match those recognized by YACE exactly.
Consult Supported Services List: Review the official YACE documentation or repository to confirm that the service you want to monitor is included in the known services list.
Update YACE Version: Ensure you are running the latest version of YACE, as support for additional services is continuously added.
Check for Deprecated Services: Some AWS services may have been renamed or deprecated; verify if the service is still current.

Understanding the Service List in YACE

YACE maintains a predefined list of AWS services it supports for metric collection. This list corresponds to the AWS CloudWatch namespaces that YACE can query. If a service is not in this list, YACE cannot retrieve metrics for it, resulting in the “Service Is Not In Known List” error.

The service list is typically defined within YACE’s source code or configuration schema and includes popular AWS services such as EC2, S3, RDS, Lambda, and others.

Service Name	CloudWatch Namespace	Description
ec2	AWS/EC2	Amazon Elastic Compute Cloud
s3	AWS/S3	Amazon Simple Storage Service
rds	AWS/RDS	Amazon Relational Database Service
lambda	AWS/Lambda	Amazon Lambda Functions
dynamodb	AWS/DynamoDB	Amazon DynamoDB

If your target service is missing from this list, it means YACE does not have built-in support for that service, and you will either need to request support from the maintainers or extend YACE yourself.

Configuring YACE to Use Custom or Unsupported Services

For advanced users, it is possible to add custom services to YACE’s configuration if the service exposes CloudWatch metrics but is not recognized by default. This requires:

Defining the correct CloudWatch namespace for the service.
Specifying the metrics and dimensions to be collected.
Adding the service to the local known services list or using a custom configuration file.

Example snippet for adding a custom service in YACE configuration YAML:

“`yaml
discovery:
jobs:

type: ec2

regions:

us-east-1
type: custom_service

namespace: AWS/CustomNamespace
metrics:

name: CustomMetric1

statistics:

Average
Sum

period_seconds: 300
“`

Note that the `type` field must correspond to a service recognized by YACE or a custom plugin/module that you have implemented.

Understanding the “Service Is Not In Known List” Error in Yace

The error message “Service Is Not In Known List” in Yace (Yet Another Cloud Exporter) typically indicates that Yace has encountered a service name in the cloud provider’s API response that it does not recognize or is not configured to handle. This situation often arises during the service discovery phase where Yace queries cloud resources and attempts to map them to known service exporters.

Yace relies on a predefined list of supported services, each corresponding to specific resource types or metrics. When an unknown or unsupported service appears, Yace logs this error to indicate that it cannot process or export metrics for that service.

Common causes for this error include:

Cloud provider introducing new services or resource types not yet supported by the current version of Yace.
Misconfiguration in Yace’s configuration file (`config.yaml`), such as typos or missing entries in the service list.
Use of custom or less common service endpoints that Yace does not recognize.
Outdated Yace version that lacks recent service updates or mappings.

Identifying Affected Services and Configuration Checks

To resolve the “Service Is Not In Known List” issue, first identify which service(s) triggered the error. This can usually be done by reviewing Yace logs or debug output, which often includes the unrecognized service name.

Step	Action	Purpose
1	Check Yace logs	Locate the exact service name causing the error
2	Review `config.yaml`	Verify that the service is listed under the `services` section
3	Validate service spelling	Ensure no typographical errors exist in service names
4	Confirm Yace version compatibility	Check if your Yace version supports the cloud provider’s current services

Yace’s `config.yaml` file defines the services to be scraped and their associated resource types. A typical snippet looks like this:

services:

  name: ec2

    resources:

  type: instance
  name: rds

    resources:

  type: dbinstance

If the unrecognized service is missing from this list, Yace will flag it as unknown.

Updating Yace Configuration to Include New or Custom Services

When a legitimate service is missing from the known list, you can extend Yace’s configuration to include it, provided that the service exposes metrics compatible with Yace’s exporter model. To add a new service:

Consult the cloud provider’s API documentation to understand the resource types and metric namespaces for the new service.
Add a new entry under the `services` section in `config.yaml` with the appropriate service name and resource types.
Verify the syntax and indentation to prevent YAML parsing errors.
Test the updated configuration locally or in a staging environment before deploying to production.

Example addition for a hypothetical new service:

services:

  name: mynewservice

    resources:

  type: myresource

Ensure that the resource type matches the API response fields, as Yace uses these to query metrics accurately.
