# Connection Logs

The **Connection Log** page in the dashboard allows Auditors to monitor workspace agent connections.
## Workspace App Connections
The connection log contains a complete record of all workspace app connections.
These originate from within the Coder deployment, and thus the connection log
is a source of truth for these events.
## Browser Port Forwarding
The connection log contains a complete record of all workspace port forwarding
performed via the dashboard.
## SSH and IDE Sessions
The connection log aims to capture a record of all workspace SSH and IDE sessions.
These events are reported by workspace agents, and their receipt by the server
is not guaranteed.
## How to Filter Connection Logs
You can filter connection logs by the following parameters:
- `organization` - The name or ID of the organization of the workspace being
connected to.
- `workspace_owner` - The username of the owner of the workspace being connected
to.
- `type` - The type of the connection, such as SSH, VS Code, or workspace app.
For more connection types, refer to the
[CoderSDK documentation](https://pkg.go.dev/github.com/coder/coder/v2/codersdk#ConnectionType).
- `username`: The name of the user who initiated the connection.
Results will not include SSH or IDE sessions.
- `user_email`: The email of the user who initiated the connection.
Results will not include SSH or IDE sessions.
- `connected_after`: The time after which the connection started.
Uses the RFC3339Nano format.
- `connected_before`: The time before which the connection started.
Uses the RFC3339Nano format.
- `workspace_id`: The ID of the workspace being connected to.
- `connection_id`: The ID of the connection.
- `status`: The status of the connection, either `ongoing` or `completed`.
Some events are neither ongoing nor completed, such as the opening of a
workspace app.
## Capturing/Exporting Connection Logs
In addition to the Coder dashboard, there are multiple ways to consume or query
connection events.
### REST API
You can retrieve connection logs via the Coder API.
Visit the
[`get-connection-logs` endpoint documentation](../../reference/api/enterprise.md#get-connection-logs)
for details.
### Service Logs
Connection events are also dispatched as service logs and can be captured and
categorized using any log management tool such as [Splunk](https://splunk.com).
Example of a [JSON formatted](../../reference/cli/server.md#--log-json)
connection log entry, when an SSH connection is made:
```json

}
}
```
Example of a [human readable](../../reference/cli/server.md#--log-human)
connection log entry, when `code-server` is opened:
```console

```
## Data Retention
Coder supports configurable retention policies that automatically purge old
Connection Logs. To enable automated purging, configure the
`--connection-logs-retention` flag or `CODER_CONNECTION_LOGS_RETENTION`
environment variable. For comprehensive configuration options, see
[Data Retention](../setup/data-retention.md).
