Downloading the Anyconnect Logs Report

[AnkitSharma1]

I need to download a report for Cisco AnyConnect sessions, showing when users logged in and logged out. I understand that this information is available in the events, but it cannot be downloaded for a three-month period. How can I obtain these reports? Please assist.

Although this won't directly answer your question there are some data retention dates for your consideration:

can I use sys logs or something?

In the future you could use the Syslog functionality to export the data on a live basis so you can have your necessary retention

What is authenticating your AnyConnect users?

If it is SAML - check your SAML provider logs.

If it is RADIUS - check your RADIUS provider logs.

If it is Active Directory - check your security event log.

You could try filtering on "AnyConnect VPN client connected", and then use the "Download" option on each page, and then join all the downloads together.
