APIs for validation and effectiveness of validators 1) https://elections.toncenter.com/docs - use this API to get information about current and past validation rounds (cycles) - time of rounds, which validators participated in them, their stakes, etc. Information on current and past elections (for the validation round) is also available. 2) https://toncenter.com/api/qos/index.html#/ - use this API to get information on the efficiency of validators over time. This API analyses the information from the catchain and builds an estimate of the validator's efficiency. This API does not use the checkloadall utility, but is its alternative. Unlike checkloadall which works only on validation rounds, in this API you can set any time interval to analyse the validator's efficiency. How to use: - pass ADNL address of your validator and time inverval (from_ts, to_ts) to API. For accurate result it makes sense to take a sufficient interval, for example from 18 hours ago the current moment. - get the result. If your efficiency percentage field is less than 80%, your validator is not working properly. - It is important that your validator participates in validation and has the same ADNL address throughout the specified time period. For example, if a validator participates in validation every second round - then you need to specify only those intervals when he participated in validation. Otherwise, you will get an incorrect underestimate. - this works not only for masterchain validators (with index < 100) but also for other validators (with index > 100). Recommendations 1) Please check the efficiency of your validator and in case of low efficiency - take action to fix the problem. Contact technical support @mytonctrl_help_bot if necessary. 2) Please set up dashboards to monitor your validators using these APIs.
