Monitoring Ethereum private network

Question

I've created a private Ethereum network and would like to explore the monitoring. I started a geth instance in one terminal window. I tried running geth monitor --attach /path/to/geth.ipc and receive the following error:

Fatal: Metric pattern trie/cachemiss resolved to unexpected type: string

What is the best way to go about monitoring the node(s) on my private network?

Answer 1

You should point out metrics in command line: geth monitor --attach ./chain-data/geth.ipc system/memory/allocs/AvgRate05Min

Important prerequisite is that geth must be started with --metrics

Answer 2

For monitoring my private network, I use a self hosted site similar to ethstats.net

• First I host an empty site using https://github.com/cubedro/eth-netstats
• Then I install an API which will send the data from my node to the site.
