Manifest for the IF docs website

[jawache]

What Create a manifest file that uses CO2js to estimate the carbon emissions from our IF docs website

Why

To dogfood our own tech!

Context

For a first attempt at capturing our website carbon emissions, we can use the Green Web Foundation's CO2js package, invoking the Sustainable Web Design Model. This uses the amount of data transferred when a site loads as a basis for a top down estimate of the carbon emissions for that website.

I'll also look into bottom-up approaches while this top-down model is being implemented.

The way I'd like to do this is for @manushak to create a manifest file that initializes the CO2js plugin and passes all the arguments that are accepted by the CO2js perVisitTrace function, returning all the response parameters as output data.

The idea would be that it a) clarifies precisely what information I need to source in order to estimate the website carbon emissions, and b) when that data is available, I just have to slot it into the right place in the manifest and run it.

SoW

• [x] @manushak creates a template manifest that runs with dummy data
• [x] @jmcook1186 sources real data for each model parameter
• [x] Real data is inserted into the manifest - running the manifets yields an estimate of CO2e/visit

Acceptance Criteria

• [ ] A manifest is available that can be run using IF to yield a carbon emission per visit.

As discussed on project call.

• There is a time component to every impact calculation.
• Every component will measure at a certain frequency, monthly, daily, hourly, minutes.
• All measurements/telemetry will have to be normalized/extrapolated/interpolated to match that global frequency for things to be summed up properly.

e.g. If two components might have different frequencies of measurement e.g. carbon intensity of grid is every 5 mins, CPU utilization every 5 seconds and the global frequency was set to 1 hour. Then all the measurements would have to be normalized into 1hr buckets before being passed into the models.

Another approach would be we define the global freq, and you MUST provide data at that frequency, if not the calculation fails.

Interval.

Can query measurements for different interval.

SCI can be calculated for a duration (and update the next duration).

Sometimes we may just want to calculate multiple SCI scores over time, e.g. every 5 mins. In that scenario the freq. will be 5 mins, and the telemetry put in will be again in 5 min increments.

@jmcook1186 can you take a look at reformatting this IMPL to one that meets the latest spec and add it to the impls folder as per your other issue. This will defo be a work in progress but let's have it added to the collection.

• Work with @osamajandali our web dev to understand the build/deploy process for our website (I guessed most of the above!).
• Make the IMPL reflect the reality of our build/deploy process.
• Source real data for say July this year (i.e. the number of builds etc.... ask Osama or you can find details in the actions tab in the website repo) also reach out to @zanete to get real traffic data regarding our website traffic.
• Try to get the data as daily observations, so one value per day for a month.
• Make this use observations (i toyed with the word measurements in this yaml but we've landed on observations)
• Remove the nodes that divide things (that will be handled by the new pipeline process)

Hi @jmcook1186 happy to help with any traffic data that would be useful. Do you have any parameters for me? e.g. timeline, the metric such as users or page views, should it be broken out by anything such as website sections, device, location etc. Look forward to hearing from you.

Hi @osamajandali and @zanete - there's a draft impl for the GSF website in PR #80 but I'd love to get your help to make it more realistic.

@osamajandali can you help by explaining how the GSF website is really built and hosted? Then I can ask @zanete for appropriate metrics.

Cheers!

Hello @jmcook1186, I am glad to assist you with any development-related queries.

The GSF website is constructed using the GatsbyJS framework and is deployed on Netlify. We utilize GitHub, which automatically builds the website on Netlify during deployment.

To better assist you, I would appreciate it if you could share more details on what specifically you are looking for. While I have provided you with a brief overview of the essential aspects, I understand that there may be additional requirements that you require further assistance with.

@jmcook1186 can we reuse this issue to restart working on manifest for the GSF website or has too much changed and we need to start fresh? 🙏

[jmcook1186]

Hi @zanete - yes we can use this ticket. A good first go at this is to use CO2js in SWD mode to estimate the website emissions from data transfer measurements. We can do this using our CO2js IF plugin.

So what I want to do is to ask @manushak to prepare a manifest that invokes the CO2js plugin and exposes all the available config for the SWD model. This will help me by enumerating all the data points I need to collect. We can divide and conquer by having @manushak prepare the manifest while I'm sourcing the right data to feed the model.

This is now just waiting for fixes to aggregation feature, then it will be done.
