# Verify your log sources in Health Log Analytics

Verify that all your log sources are present and active. Health Log Analytics tagging assigns logs to service instances and components, and automatically maps logs to sources.

## Before you begin

Role required: evt\_mgmt\_admin

## Procedure

1.  Navigate to **All** > **Health Log Analytics** > **Data Input** > **Log Sources**.

    The Log Sources table provides information about the sources created when you mapped the streaming data. The table lists these sources by service instance.

<table id="table_wx1_kt1_gnb"><thead><tr><th>

Column

</th><th>

Description

</th></tr></thead><tbody><tr><td>

Service instance

</td><td>

The service instance. Service instances represent large or complete business processes. A single service instance can consist of multiple components, whereas different service instances can include the same components.

</td></tr><tr><td>

Component

</td><td>

The components comprising the service instance. Components represent small technical parts or business processes. Typically, they represent Configuration Items \(CIs\). Several components are often clustered together in a single service instance.

</td></tr><tr><td>

Status

</td><td>

The status of the log source: Active or Inactive. The Active status indicates that logs streamed into the system from this source in the last hour.

</td></tr><tr><td>

Created

</td><td>

The creation date and time of this log source.

</td></tr><tr><td>

Last event time

</td><td>

The last time logs streamed into the system from this source.

</td></tr></tbody>
</table>2.  Make sure that the system has created all your log sources.

3.  Verify the creation, status, and log samples of a specific source in the source record.

    **Note:** Because auto-mapping can map log data to multiple sources, be sure to verify this information per source.

4.  If a log source is missing, add it.

    1.  Navigate to **Health Log Analytics** &gt; **Data Input** &gt; **Data Input Mapping**.

    2.  Use the JavaScript function to manually map a log sample to the correct service instance, component, and source type.

        For more information, see [Map raw log data manually](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/it-operations-management/health-log-analytics/hla-data-input-mapping.md).

    3.  Navigate back to the Log Sources page and verify that the status of the new log source is Active.

    The system creates a log source.

5.  Make sure that the status of all your log sources is Active.

    If the status of a source is Inactive, double-click it and change it to Active manually.

6.  Select **Update**.
