How to check ethereum logs

0 votes
I have created a private ethereum network and when I run a command or a transaction I only see the result or output there but, I want to see what happens in the background. Is there like a Verbose option or a log where I can see all the things happening in the background?

Hey there! You don't have a Verbose option but you can see what's happening in the background by reading the logs. To do this, you have to set the log file to store the data and then read it. Follow this steps:

Initialize the data directory and start the peer node:

geth --datadir ./myDataDir init ./myGenesis.json
geth --datadir ./myDataDir --networkid 1114 console 2>> myEth.log

Note that while starting the peer node, we are sending the logs to the myEth.log file.

Now, to read the log, open a new terminal, switch to the directory where  myEth.log   file is stored and run the following command:

tail -f myEth.log

This will display the logs. Whenever you run a geth command or make a transaction, this window will dynamically get update.

Hope it helps!
