How do I see staked Solana?

As a keen observer of the cryptocurrency landscape, I'm particularly intrigued by the staking phenomenon and Solana's role in it. Could you elaborate on how one can track or visualize their staked Solana? Is there a specific platform or tool that offers this functionality? Furthermore, what are the key metrics or information points that a stakeholder should be mindful of when monitoring their stake? Understanding this process is crucial for me to make informed decisions and optimize my staking experience.
