How can I figure out what the total ram of the system currently is?

Question

Is there a way to know what the total system ram currently is?

Is it the balance in bytes?

$ ./cleos -u http://localhost:8080/ get table eosio eosio rammarket
{
  "rows": [{
      "supply": "10000000000.0000 RAMCORE",
      "base": {
        "balance": "67296295696 RAM",
        "weight": "0.50000000000000000"
      },
      "quote": {
        "balance": "1021151.0869 EOS",
        "weight": "0.50000000000000000"
      }
    }
  ],
  "more": false
}

Answer 1

Yeah, the base balance is the balance of unused RAM in bytes. To get the total ram, check the global table instead:

$ cleos get table eosio eosio global

{
  "rows": [{
