bitcoind_ - Track Bitcoin Server Variables
=head1 CONFIGURATION
You need to be able to authenticate to the bitcoind server to issue rpc's.
This plugin supports two ways to do that:
1) In /etc/munin/plugin-conf.d/bitcoin.conf place:
[bitcoind_*]
user your-username
env.bitcoin_configfile /home/your-username/.bitcoin/bitcoin.conf
Then be sure that the file referenced above (typically: $HOME/.bitcoin/bitcoin.conf)
has the correct authentication info:
rpcconnect, rpcport, rpcuser, rpcpassword
2) Place your bitcoind authentication directly in /etc/munin/plugin-conf.d/bitcoin.conf
[bitcoind_*]
env.rpcport 8332
env.rpcconnect 127.0.0.1
env.rpcuser your-username-here
env.rpcpassword your-password-here
To install all available graphs:
sudo munin-node-configure --libdir=. --suggest --shell | sudo bash
Leave out the "| bash" to get a list of commands you can select from to install
individual graphs.
