Now that I produce three weekly posts I can't really reproduce them here anymore so I'm going to link to them and include some interesting images instead.

Would be nice to get the % of total hashrate (either instead of or along side nominal hashrate).

The % is more important to be (especially for the largest pools).

Blockchain.info has nice pie charts but I would love to see something showing the % over time.

Good idea, add a column and a second axis to the graph. But over time? You mean a plot of % vs hashrate for each pool? I could do a lattice plot, sort of a bunch of miniplots for each pool. It would get a bit messy. Or did you mean just that the thread would contain that history?

It likely is asking too much but if you record the weekly average of each pool and then convert them to a % you could make a chart over time with the % of each pool (line chart or stacked bar chart, etc).

i.e. something like (but in chart form)
Code:

Pool   Week1 Week2 Week3 Week4
PoolA  10%   11%   12%  11%
PoolB  15%   13%   10%   8%
PoolC   9%   11%   12%  11%

Deepbit has the last 5 days available, so the average is based on that.
All the data since pool's start is available in the same way, just change the unixtime in the link.
(Use appropriate delay between requests to avoid being blocked if you want to download many days in a row)

That'd work, if I just did it for say the largest three pools. Cool.

Deepbit has the last 5 days available, so the average is based on that.

Cheers Deepbit. I'll change it next for next week. Hopefully only need to download it once a week.

Blockchain.info is cool, but please don't use their data on block's origin, it may be way off.
This site provides correct percentage for many of the listed pools: http://blockorigin.pfoe.be/top.php
(Some pools don't publish their block hashes, so their info is sometimes wrong too)

I'm writing a script to pull down the nethash data once a week from blockexplorer.com/q/nethash. I can get the total hashes and total time, which should give me an average hashrate for the week. I think.

You totally need to have EMC on there.

Percentage of network hashrate now added to the OP (thanks for the idea, D&T). I'll keep a chronological table of the percentages in the OP.

If you are expanding to include the top 10 then p2pool should definitely be included.

Not the top 10, just pools with a stats API or scrapeable stats page. I'd like to include p2pool, but the only p2pool stats page I could find isn't scrapeable. If you know of a way to get the block timestamps and total round shares for the previous seven days I'll include it next week.

p2pool uses dynamic shares so that isn't going to be useful.  If you run a p2pool node (you don't need to use it for mining) the node will track avg hashrate of the pool for you.

I knew about the dynamic shares used and I was wondering how a pool hashrate could be calculated - I'm so used to calculating the average hashrate from timestamps and round shares that I didn't even think of tracking the actual hashes submitted Embarrassed

So does running a p2pool node give actual data as well as graphs in order to get a seven day average?  (duh, just looked more closely at the graph). And would it need to be on constantly?

Yes the raw data is available both as raw shares, in the log and in summarized format (what is used for the graph).

p2pool would need to be constantly running because while nodes record everything only shares in the main chain in last 24 hours are required for reward calculation.  When a node comes online it will only request information that is required (shares in main chain in last 24 hours) so it can compute the reward split.

Each p2pool share contains within it the target difficulty so the sum of the hash difficulties gives you the # of hashes they represent.
global avg hash rate = (sum of p2pool hash difficulties in the period) / ( (2^32) * (time period in seconds) )

Thanks for the explanation. Unfortunately I don't have any computers I can run 24/7 (which is one of the reasons I had to quit mining). But if you (or any p2pool miner) would like to repost that same 7 day chart on the day before I post new weekly hashrates, I'll be able to include it in the data manually.

I could do that but it would be cumbersome however many people make the their p2pool nodes public.

Here is forrestv (p2pool developers) node:
http://forre.st:9332/static/

It might be easier to just grab the data when you need it.
