I've made the following tweaks:

1. Updated MT engine total character counts to display MinT
2. Updated Quantiles - removed p10 values as the value 10 for histogram_quantile doesn't make sense, which only accepts values between 0-1.

Regarding the values in the Quantiles, while they look incorrect, I can't tell what's wrong by looking at the query.

In the Quantiles graph, all values were there, but count value 1 caused it hiding all other graphs. I disabled that it looks ok now.

Cool, that makes sense.

Pending item:

MT engine total character counts graph get reset often making the numbers not reliable

Current values displayed as of 2025-01-13 - 1730 UTC:

Graph appears to have reset:

We did a production CXServer deployment today, and it appears that the MT engine total character counts graph got reset:

Pre-deployment

Lets try to see if the behavior continues a couple of more times.

The graph doesn't appear to have reset since Friday:

Something like "expr": "sum(increase(translate_Apertium_charcount[$__interval]))", could help in Grafana to avoid resets due to service restarts.

Tried that. It shows no data for anything less than the last 2 days which is weird.

I ended up using: sum(increase(translate_Apertium_charcount[$__range]))

• The increase() function calculates how much the counter increased over a given time window.
• $__range is the user-selected time range (e.g., if the user selects "Last 3 hours", then $__range = 3h).

This does the following:

• Finds how many characters were translated in the last $__range (e.g., last 3 hours).
• Handles resets automatically (if the counter drops due to a service restart).

This appears to work well:

Last 15 minutes	Last 3 hours	Last 12 hours	Last 24 hours

I played around with the dashboard. It looks good to me.
