Finding work at my consulting job has been a struggle

I have been at my current consulting job for about a year. I frequently don’t have anything to do and my metrics suffer for it. I have no idea what I’m supposed to put on my time card or how to fill up an admin week. My utilization is tracked and scrutinized based on billable project hours yet I can’t seem to find any work despite how many people I ask. My manager just tells me there’s nothing for me right now. What am I supposed to do?
