License expiration nearing-cisco-nxos

Vendor: cisco

OS: nxos

Description:
indeni will trigger an issue when a license is about to expire.

Remediation Steps:
Renew any licenses that need to be renewed.
||1. Run the “show license usage” NX-OS command to display information about the current license usage and the expire date.
|2. Run the “show license” NX-OS command to view the installed licenses.
|3. Run the “show license usage XXX” NX-OS command e.g.” sh license usage ENHANCED_LAYER2_PKG” to display information about the activated features which utilize this license.
|4. Consider activate the grace-period for the license.
|5. Order new license from the CISCO.
|6. For more information please review: Cisco Guide

How does this work?
This script logs into the Cisco Nexus switch through SSH and retrieves license usage infromation using the “show license usage” command.

Why is this important?
Collect information about license usage and report any licenses which are in their Grace period. This would report any license which is in use but has not been purchased/activated on the device.

Without Indeni how would you find this?
Expiring licenses generate syslog messages close to and at the time of expiration. The user has to detect those log entries and take an emergency action to install the required licenses. Missing these events may result in an outage.
