How to see pending transactions in local geth node?

I’m looking for run a local node and get pending transactions

Since 3 days runing, no pending transactions appear

> txpool.status
{
  pending: 0,
  queued: 0
}

And I use this command line (last version of geth)

geth --datadir=~/dev/chain --syncmode fast --cache 6144 --rpc --rpcaddr '0.0.0.0' --rpcapi=eth,net,rpc,web3,txpool,personal,debug --txpool.globalslots=250000 --txpool.globalqueue=500000 console

Is the command line wrong ?
