Arch Systems does not recommend that customers spend their time attempting to prove the consistency of metrics across GLO KPI Sets, Grafana Dashboards, and ArchFX Batch Reports. Arch Systems has Quality Assurance staff who do this already for you, and in our experience, customers who attempt to validate the consistency of metrics by themselves spend much of their time aligning time zones and time periods across the three applications only to prove in the end that when time zones and time periods are correctly aligned, the metrics are consistent across the applications as one would expect.
Customers who nonetheless wish to validate metrics should contact their commercial team and ask for access to the Arch validation tool, which enables customers to export raw source data and calculated metrics at the command line for further analysis in the applications of the customer's choosing.
If a customer still wishes to attempt to compare and validate metrics across GLO KPI Sets, Grafana Dashboards, and ArchFX Batch Reports, following are important things customers must keep in mind about time periods and time zones across the three user experiences.
Metrics in GLO KPI Sets
Metrics for a site in GLO KPI Sets are defined in terms of the Factory Day which is relative to the start time of the day's first shift in the local time zone. Read How is the Factory Day defined in GLO KPI Sets? for more details about the definition of the Factory Day.
When a metric is being aggregated across multiple sites, the data for each site in the site's local Factory Day is aggregated with the data for each other site during the other site's Factory Day in own local time zone to define the Global Factory Day which follows the sun around the globe.
Metrics in GLO KPI Sets can only be defined in units of days, not smaller time periods like hours. Metrics in GLO KPI Sets are available as far back in time as when the customer began using ArchFX at a given site.
Metrics in Grafana Dashboards
In Grafana Dashboards, you specify the exact period of time you want to use via the date range selector in the top-right corner of the dashboard. The date range selector lets you use either absolute time periods (e.g. "2025-03-01 08:00" through "2025-03-02 08:00") or relative time periods ("now - 2d" through "now"). Dates and times are defined relative to the time zone that you also choose within the date range selector.
Metrics in Grafana Dashboards go back a limited time period (typically at least the last two weeks) because they rely on running raw SQL queries that become computationally prohibitive over longer periods of time.
Metrics in ArchFX Batch Reports
Metrics in ArchFX Batch Reports are defined in Universal Time Code (which is loosely speaking similar to Greenwich Mean Time).
Metrics in ArchFX Batch Reports are available as far back in time as when the customer began using ArchFX at a given site.
Example: comparing a metric across GLO KPI Sets and Grafana Dashboards
Let's say that in your ArchFX deployment, "Planned Downtime" is shown as a metric in both the React Downtime Inspector and within GLO KPI Sets and you wish to validate that the values reasonably match. It is best to use the Arch validation tool as described above for metrics validation, but if you want to compare values across applications in the user interface, the best approach is as follows:
- Check the value in GLO KPI Sets for a recent one-day period. e.g. you could set the GLO KPI Sets date range selector to "Day" and choose 2025-09-24 as the date. GLO KPI Sets would calculate "Planned Downtime" for the 2025-09-24 Factory Day which runs from the start of the first shift at that site in the local time zone through the end of the last shift for that Factory Day in the local time zone:
- Check the same value in the React Downtime Inspector for the exact same one-day period. In the React Downtime Inspector time range panel, first set the time zone to the local time zone for the site. Then, specify the exact same time period in absolute time values. If the factory was in Juarez, Mexico and running three eight-hour shifts starting at 5:00 a.m. local time, that would be start time From "2025-09-24 05:00" and end time of To "2025-09-25 05:00" as shown below:
