Argo Percentage of Requests is almost Zero%

Hi,
I activated Argo over a day ago.
When I check the Argo analytics Histogram, I can see that the Percentage of Requests is almost Zero%.
I can’t understand if this is good or bad as the help article does not explain how to read the histogram

.

Can someone help me reading the histrogram, please?
Thanks in advance.

:wave: @coptic-treasures,

82% of the requests to your origin were smart routed. The average TTFB improvement was 25%.

The chart shows a histogram of the TTFB of all requests to origin and whether they were smart routed or not.

Hi @coptic-treasures!

How tall a bar is in this chart represents how many requests (in %) were served. Where that bar is placed represents response time in milliseconds.

Ideally you’d want to have most of your traffic (tall bars) being served in as few milliseconds as possible (bar being seated near the left side).

In your case the orange bars are more to the left than the blue ones, meaning that more requests were served at a faster pace than without using Argo, so it seems it’s doing well.

also the help info on analytics/performance argo page has some explanation

Above is a histogram of Time To First Byte (TTFB). The blue and orange series represent the before and after TTFB in locations Argo found a Smart Route.

TTFB measures the delay between Cloudflare sending a request to your server and receiving the first byte in response. TTFB includes network transit time (which Smart Routing optimizes) and processing time on your server (which Argo has no effect on).

but really only need to be concerned with percentage of improvement and percentage of smart routed requests.

If you query CF Argo analytics API, you can also get per CF datacenter statistics which can break down how Argo is performing per CF datacenter

example of my custom Argo analytics API query per CF datacenter metrics where you can see the best % argo improvement was max = 0.6718 = 67.18% improvement from CF datacenter BOM for India which makes sense as it’s further region from my US West Coast server origin location. While least % argo improvement = 0.2453 = 24.53% improvement came from CF datacenter SEA for US West Coast due to closest region to my origin server US West Coast location.
