bug: Exchange rate not working

[sossickd]

Describe the bug
Exchange rate doesn't appear to be working.

To Reproduce
Steps to reproduce the behavior:

1. Install OpenCost with any image or helm chart version on AWS.

Check the Opencost UI dashboard.

In this instance i am selecting TTD

When i switch to THB

The price is the same.

I now compare that to the AWS Cost Explorer and i don't get a selection for currency.

Is AWS plugged into the exchange. Profound right?

There is no currency calculation being performed in OpenCost, we're simply recording what's exposed in the API for the value of the cost and recording it. The currency drop-down in the UI is cosmetic and there is no currency associated with the recorded values in Prometheus.

I can see how this is an issue if you were doing multiple clusters across multiple currencies and consolidating them to a single database, but that's currently outside our primary scope.

That said, is Cost Explorer showing values different from what we're displaying? That would be an interesting bug, since we're getting costs from their pricing API but it's showing you something different. What currency are you paying your bill in vs. what are you looking at in their UI? I'm not sure how we'd tackle that if it's an issue, but please report back.

If you did tie into the exchange rate would this help?

From a cosmetic principle would it be a nice idea to use currency symbols?

I really feel like we need this feature

Well done me know one else, Hope you have a very lovely Christmas

This is could be very important If the the AWS business model
Doesn't allow to move to
An exchange rate that is more financially beneficial to the customer, might be worth more investmention

Currency in opencost is currently only for display; whatever comes out of the pricing URL will be what's in the application, from the time at which it was selected going forward. An actual conversion module would be interesting though, I think we could take a PR there.

[nishikant]

As I understand default currency, not changeable, is USD and opencost team is avoiding adding any thirdparty dependency on currency conversion api.

But on changing currency, a simple input box asking the currency conversion rate from user,(with basic validation of input) and use it to calculate cost. This way no hard dependency on thirdparty conversion rate api and easy fix for a critical issue.

Would support a PR for conversion on the frontend!

@AjayTripathy , I added a "conversion rate" textfield and button to get the conversion rate value as input and on submission to apply the rate on all allocation resource metrics. Can you please take a look?

I did not add support for a third-party exchange API based on the comments above.
