Someone know how can read new audit system in storagenode API?

You can take a look on these scripts: My uptime should be 100% on all satellites i have not gotten any uptime robot notifications of downtime in months - #2 by Alexey
on the endpoint /api/sno/satellite/121RTSDpyNZVcEU84Ticf2L1ntiuUimbWgfATz21tuvgk3vzoA6 you can get a json, it has "audits" field, i.e.

bash -c "curl -sL http://localhost:14002/api/sno/satellite/121RTSDpyNZVcEU84Ticf2L1ntiuUimbWgfATz21tuvgk3vzoA6 | jq '.audits'"
{
  "auditScore": 1,
  "suspensionScore": 1,
  "onlineScore": 0.9996647694367379,
  "satelliteName": "ap1.storj.io:7777"
}

But there is no endpoint to see a count as far as I know, except summarizing onlineCount across all windows on auditHistory. But it will provide a count of answered audit requests, not the successful audit requests (they can differ, if there is corruption or missing piece), because these counts are used only to determine an online score.
