Synthetics Overview success data incorrect
Hi, I've been reviewing the data for our Synthetics Canaries, and have noticed something odd on the Synthetics Overview dashboard. It seems like the "Success %" data is not consistent with the actual canary results. For example, I see 100% success reported on canaries whose last run ended in failure, and 0% reported for canaries which recently had a successful run. Can anyone advise why I'm seeing this discrepancy, and how I can ensure there are accurate success stats available?

The discrepancy you're seeing in the Synthetics Overview dashboard regarding the "Success %" data not matching the actual canary results could be due to Metric calculation period.
The "Success %" on Synthetics Overview dashboard seems to be calculating over a specific time period based on the time range selected. on the, "Synthetics Overview" console, can you try changing the time range. For example, select "Relative" and try checking for last 5 mins, 30 mins etc to confirm if the "Success %" change accordingly.
Canaries publish "SuccessPercent" metric to CloudWatch in the CloudWatchSynthetics namespace, which shows the percentage of the runs of the canary that succeed. Can you use the CloudWatch console to view the SuccessPercent metric, and confirm if there's still discrepancy in metrics.
If the issue persists after trying these steps and for detailed investigation, we would need to check the resources and other details with respect to your account. If you still have queries regarding this, I would request you to reach out to our support by opening a support case with all the resource details, and we will investigate the issue further.

Hi Ashish,
I've generally been trying to pull a week's worth of data, using the "1w" selector from the Synthetics overview board. But regardless of the timeframe, there are inconsistencies between this Success % and the actual results.
For example, looking at one canary, the summary page shows "Last run status" as Passed, and Success Rate of 0%. When I drill down into the canary's details, I can see that each run during the selected timeframe passed. So... where is the 0% coming from?
Thanks, Josh
