New SINCE Functionality and stddev() Function for Insights

New Relic has introduced a new "SINCE" functionality to its Insights platform, allowing users to query data based on specific time ranges, such as "SINCE today" or "SINCE this week," and exclude particular periods like maintenance windows. This enhancement in NRQL, Insights' query language, enables more precise queries, such as examining backend response times during peak hours or changes in error rates during maintenance. Additionally, a standard deviation function (stddev()) has been added to help identify anomalies in data patterns, exemplified by its use in detecting spikes in transaction errors. These updates aim to broaden the scope of questions users can ask about their applications, providing more tailored insights into their business operations.
