@Priya Tiwari Greetings!
Changing the advisor lookback period from 30 days to 60 days in Azure Advisor primarily affects how recommendations are generated based on your resource usage and performance data. Extending the lookback period from 30 days to 60 days will increase the amount of historical data that Advisor uses to generate recommendations. This might get you more comprehensive insights into usage patterns, which could help you identify additional cost-saving opportunities., but it can also increase the cost of running Advisor. This is because Advisor uses machine learning algorithms to analyze the historical data, and the more data it has to analyze, the more resources it will consume.
However, the cost impact of changing the lookback period from 30 days to 60 days is likely to be minimal. The Advisor service is designed to be cost-effective, and the cost of running Advisor is based on the number of resources you have in your Azure subscription. The cost of running Advisor is also included in your Azure subscription, so there are no additional charges for using the service.
In short, changing the Advisor lookback period from 30 days to 60 days may have a small cost impact, but it is unlikely to be significant. The benefits of more accurate recommendations may outweigh any additional costs.
