Traces for a Service

LogicMonitor creates a service using LM Service Insight for each of the received service trace data. LogicMonitor creates this service when you specify the mandatory “service” OpenTelemetry configuration value. If you specify the optional service namespace in the OpenTelemetry configuration, the value is added as a property to each auto-created service and a parent service is created representing this namespace. This is useful when you have applications with multiple underlying services.

For example, you may have an application “ECommerce” with the following underlying services: “Frontend”, “Cart API”, and “DB”. If you instrument the application with the service name as the “service” configuration flag, and “ECommerce” as the “service namespace”, then LogicMonitor creates the following:

• ECommerce service representing the whole application.
• Three services belonging to the ECommerce service:
  • Frontend service
  • Cart API service
  • DB service

Service-level Traces

LogicMonitor automatically creates services for each unique “service” value in the forwarded traces. For each service, LogicMonitor automatically monitors the Duration, ErrorOperationCount, OperationCount, and UniqueOperationCount metrics:

Metric	Description
Duration	The average time taken by all operations within the service
ErrorOperationCount	The number of error operations
OperationCount	The total number of operations within the service
UniqueOperationCount	The number of unique operations within the service

For each Service that represents a namespace, LogicMonitor monitors the following aggregated metrics:

Metric	Description
total requests	The total number of requests for all operations in the Services
request rate	The average request rate for all operations in the namespace
total errors	The total number of errors across all operations in the namespace
error rate	The average error rate for all operations in the namespace
average duration	The average duration across all operations in the namespace
max duration	The max duration across all operations in the namespace
95th percentile duration	The 95th percentile duration calculated across all operations in the namespace

You can set static or dynamic thresholds on these metrics globally when defining the DataSource, at the group level, or for a specific resource.
