Low Identity Awareness User Count-cisco-ios

Vendor: cisco

OS: ios

Description:
Indeni can identify if the current Identity Awareness User Count is below acceptable levels during active hours.

Remediation Steps:
Please review the following article to determine the root cause behind the low count: http://downloads.checkpoint.com/dc/download.htm?ID=12625. Otherwise, contact your Check Point technical support provider. If the threshold is too sensitive, please request for the Indeni threshold to be modified as necessary.

How does this work?
This script logs into the Cisco IOS device using SSH and retrieves the configured time zone using the output of the “show clock” command. The output includes the current time and configured time zone, i.e. EST for Eastern Standard Time. If the time zone is mismatched across vPC domain (cluster) members an alert will be triggered.

Why is this important?
Capture the time zone setting of the device. Time zone denotes offset from Coordinated Universal Time (UTC).

Without Indeni how would you find this?
It is possible to poll this data through SNMP although there is no way to correlate across vPC domain (cluster) members without additional logic. can-with-snmp: false can-with-syslog: false

    current-datetime:
        why: |
            Capture the current date and time of the device. Device current date and time should never be more than 24 hours
            away from date and time of the device polling the data, otherwise date and time are not correctly set on device.

            This script logs into the Cisco IOS device using SSH and retrieves the current time using the output of the
            "show clock" command. The output includes the device's current date and time as well as configured time zone.
