This read-only counter tracks the number of Single Sign-On (SSO) authentication token attempts processed by a Juniper MAG Series gateway, a device used for secure remote access and identity federation. An administrator monitors this to gauge SSO usage volume and, when compared against jnxMagSSOFailedAuthToken, to calculate a rough success rate for SSO logins passing through the gateway. For example, a steady, expected baseline of attempts each business day, followed by a sudden large jump, might indicate either a new integration coming online or a brute-force attempt against the SSO endpoint worth investigating.
