Known Issues

• If SSH connection get closed by the target, the exporter will not reconnect automatically. You need to restart the exporter.
• If modem is highly loaded (e.g. full bandwidth Steam downloads), the export process might take longer than the default scrape interval of 15 seconds. This will result in a timeout and the modem will not be scraped by Prometheus. You can increase both of the scrape interval and timeout to avoid this issue.
