Secure Access and Certificate Configuration

To access IO Monitor over a secure HTTPS connection, a trusted certificate must be configured. You can either use the default self-signed certificate or create a locally trusted certificate.

Option 1: Default Self-Signed Certificate

If a locally trusted certificate is not configured, IO Monitor automatically generates a self-signed certificate for HTTPS. When accessing IO Monitor for the first time from a client machine, your web browser will display a security warning.

To proceed:

  1. Click the Advanced button on the warning page.

  2. Select Proceed to [IP Address] to open IO Monitor.

Even after accepting the certificate, the browser may continue displaying a warning symbol in the address bar. However, the connection remains secure.

Option 2: Configure a Trusted TLS Certificate

You can map your own trusted certificates to avoid the browser security warning, refer to How to Configure TLS Certificates to Avoid Innocuous Browser Warnings.

If the browser keeps loading the page without progressing, try clearing the cookies.

IO Monitor Quick Start

When instruments connected to your PC are recognized by Connection Expert, you can track their activity using IO Monitor.

As you send commands or read responses in Connection Expert, IO Monitor captures the messages, making it easy to review them in just a few steps:

  1. On the IO Monitor screen, select the Start button.
  2. In Connection Expert, go to Instrument View, then in the Action column, right‑click the gear icon and select Check Connection Status. Watch as the I/O messages generated by the refresh operation appear on the IO Monitor display.
  3. When finished, click the Stop button on the IO Monitor display.

Important Considerations

  • IO Monitor is not a performance measuring tool; IO Monitor itself affects performance.
  • Only one session of IO Monitor can run at any time per machine.
  • When monitoring for a longer duration and when message volume is high, IO Monitor may lose messages.
  • When monitoring SICL and/or SICL Detail, IO Monitor may monitor, display, and/or log many messages from the Keysight Instrument Discovery Service. To reduce the number of messages, turn off the SICL and SICL Detail options. See Changing IO Monitor Settings for details.

Keysight IO Libraries Suite Documentation
