Web Wireshark

Web Wireshark won't start or connect?

Troubleshooting steps:

1. Verify Docker is running: Run docker ps on the GNS3 VM to confirm the Docker daemon is active
2. Check network connectivity: Ensure the GNS3 VM can reach Docker Hub (or has the image pre-loaded)
3. Review configuration: Confirm the [WebWireshark] section in gns3_server.conf is correct
4. Check logs: Look for error messages in the GNS3 log console
5. Inspect container logs: Run docker logs gns3-wireshark-{project_id}

How to adjust Web Wireshark resource allocation (memory, CPU)?

Edit the [WebWireshark] section in gns3_server.conf:

[WebWireshark]
memory = 4g   # Container memory limit (default 2g)
cpus = 2.0    # CPU cores (default 1.0)

Recommended configuration by concurrent instances:

Concurrent instances	Recommended memory	Usage
4-6	2g	Default, moderate usage
7-10	4g	Heavy usage
10+	8g	Large topologies
