Since it seems unlikely that we'll be able to ship an integrated stats / monitoring feature in the short term, I went ahead and set up a public Statoshi instance and threw a nicer interface on top of it.

http://statoshi.info

You can also view the raw Graphite stats at http://statoshi.info:8080/

If there are any metrics that you think would be helpful for development or monitoring purposes, just let me know and I'll take a shot at adding them.

Must say it looks very nice.

One comment about the graphs: in the 'connected peers' chart you
visualize some larger quantities (especially knownAddresses) and some
very small ones (peer.(dis)connect). This makes the latter invisible
due to scale.

Some random stats may be useful as well:

- Number of connected peers that are SPV clients or full nodes (NODE_NETWORK)
- Current block height (so that it's possible to detect stuck nodes)
- Number of transactions in mempool
- Number of transactions in UTXO set
- Maybe some fee statistics,
https://github.com/bitcoin/bitcoin/pull/3959 would be useful here
- Number of orphan blocks/orphan transactions

I agree, it looks very slick.  Well done.

While on the subject of connected peers, what about the idea of adding the ping time from this node to other peers?  The problem with fitting that information into the current design is that the graphs seem to be comprised of overall statistics for this node, not per-peer statistics that can vary between peers (such as ping time).  If a line were to be added to a graph to represent each peer's ping time, the number of lines (statistics) on the graph would have to vary in real time as peers are added or removed, which would be a challenge.

I earlier added the "ping" feature to bitcoind, and it works to measure the ping time, however this feature is on-demand: it won't ping other nodes unless requested.  So, something would have to send the "ping" RPC command on a regular schedule, to ensure the graph is updated with new information.  Also, there is currently no support for overlapping pings (although that would be easy to add), so if a peer is slow enough to not respond at all to the first ping request, and a second ping request goes out in the meantime, any late response from the first ping request would then be discarded.

Great graphs, and these are just brainstorms for future ideas :)

Thanks; I've received several suggestions for other metrics to collect that I hope to implement soon, but you're right in that tracking per-peer pings is a different type of metric than what I'm currently collecting. I actually noted the lack of pong messages in a post I made a few weeks ago: http://coinchomp.com/2014/04/27/peeking-hood-running-bitcoin-node/

Once I added metrics for sent messages, it validated my theory: my node has never sent a single ping request to a peer and thus has never received a pong message. I can't even add sent pings or received pongs to this chart because they don't exist in my graphite instance. http://statoshi.info:8080/render/?width=1548&height=883&_salt=1400066995.622&target=stats.message.received.ping&target=stats.message.sent.pong&lineMode=connected&bgcolor=000000&fgcolor=FFFFFF

I guess my question regarding ping stats is how useful that information would be - it seems to me that if we are trying to quantify the cohesiveness of the network, we should instead be observing the message propagation times. Though that's outside the scope of my project; there are other people who are doing just that.
