Python plugin for collectd to query bitcoind via rpc.
This is based on a python script from C-Otto found at: https://gist.github.com/C-Otto/a9e4864dff1a2b167761
This is also based on a python script by nomnombtc: https://github.com/nomnombtc/collectd-bitcoin
Mostly changes to make the query code work within the collectd plugin environment.
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 Python plugin:
LoadPlugin python
Put something like this into collectd.conf assuming that your plugins
live in /opt/collectd_plugins:
<Plugin python>
ModulePath "/opt/collectd_plugins"
Import "collectd-bitcoin-plugin"
</Plugin>
example.py A simple script to read getblockhash from your bitcoind node and print the result to the console
test.py A simple script that shows how to read bitcoind values and feed them to collectd
example-ssl.py A simple script to query a remote bitcoind node that is available via SSL on port 443
For example-ssl.py you will need to set the path to the self-signed pem file or the SSL connection
will fail:
export SSL_CERT_FILE=<path-to-pem-file>/server.pem
If you are using a self-signed pem for the reverse proxy on the bitcoin node, just copy that file to the
local directory and set the environment variable as shown above before running the example Python code.
