We suddenly started getting a rash of alerts from our monitoring tool (OpManager) today and can't figure out why we are getting them. We were getting alerts for our ASA5500's first then it was showing up on some of our 1841 routers. We are getting AuthenticationFailure messages, an attachment shows the error.
I'm wondering why it alerrts on system uptime??? What should I be checking, I'm not too familiar with interpreting these errors.
