Small python snippet to query bitcoind via rpc and log with collectd
This is based on a python script from C-Otto found at: https://gist.github.com/C-Otto/a9e4864dff1a2b167761
Biggest change is that it uses rpc connection instead of calling bitcoin-cli binary and added some more stuff to log.
Together with something like CGP it can generate nice graphs:
(Note if you use CGP, there is a custom plugin to control colors/naming scheme in the CGP/ subfolder.)
Needs a running bitcoin-{core,classic,unlimited} daemon with rpc user/password set.
This is needed to connect via rpc: https://github.com/jgarzik/python-bitcoinrpc
Replace rpcuser and rpcpassword with your bitcoind rpc username/password in the script.
Enable collectd exec plugin:
LoadPlugin exec
and put something like this into collectd.conf
<Plugin exec>
Exec "nobody:nogroup" "/path/to/script/collectd-bitcoin.py"
</Plugin>
