# Logging for IBM Quantum Compute Service

IBM Cloud® services, such as IBM Quantum Compute Service, generate platform logs that you can use to investigate abnormal activity and critical actions in your account, and troubleshoot problems.

You can use [IBM Cloud Logs Routing](https://cloud.ibm.com/docs/logs-router?topic=logs-router-about), which is a platform service, to route platform logs in your account to a destination of your choice by configuring a tenant that defines where platform logs are sent. For more information, see [About Logs Routing](https://cloud.ibm.com/docs/logs-router?topic=logs-router-about).

You can use [IBM Cloud Logs](https://cloud.ibm.com/docs/cloud-logs) to visualize and alert on platform logs that are generated in your account and routed by IBM Cloud Logs Routing to an IBM Cloud Logs instance.
