Hi, im new to dynatrace and Im having trouble creating an anomaly detection that will verify the increase of a metric for a period of 24h. Here is the query im running in the data explorer page. ![audiokarate_0-1716820056612.png](https://global.discourse-cdn.com/dynatrace/original/2X/c/c0c979669a9e277c6a1f5ab402b2d515ba93f6aa.png) However when I create my anomaly detection it doesnt include the 24 hours filter… Do i need to modify my query to add a timeframe if so how can i do this? ---

Maybe you are looking for this the [Metrics API - Metric selector — Dynatrace Docs](https://docs.dynatrace.com/docs/shortlink/api-metrics-v2-selector#timeshift) ? ---

i tried that before opening the ticket and its not giving me the result i need i need to be alerted if my metric does not increase by at least 1 in the last 24 hours… see screenshot below ![audiokarate_1-1716829190316.png](https://global.discourse-cdn.com/dynatrace/original/3X/3/2/324e667101d198e5ed307a3e829dc05ffdbee66d.png) ---

Try to do a calculation (your metrics with timeshift) - (metric without timeshift) ![PacoPorro_0-1716878602631.png](https://global.discourse-cdn.com/dynatrace/original/2X/8/8e53a1c730347dc56fc61bf9d6c43896c83511e2.png) ---

So, livraison and observability-cac ran 163 successful backup in the last 24h, and also 163 in the interval from -42h to -18h.  Looks like the expected behaviour is to have the same number of backups in the last 24h than in previous period. ---

actually we run only 4 backups a day (every 6h) and i have to make sure that there was atleast one sucessful backup in the last 24h. I have no idea where this 163 value is coming from. We are in the process of doing the migration of our monitoring from prometheus to dynatrace. If i compare the exact same metric in dynatrace and in in prometheus im getting different results (see both graphs below) ![audiokarate_0-1717001692438.png](https://global.discourse-cdn.com/dynatrace/original/2X/9/9b57802d21e1f095a4e378e3583833af89137ae6.png) ![audiokarate_1-1717001710526.png](https://global.discourse-cdn.com/dynatrace/original/3X/6/4/64de6bbc63d19254dc899cbc36136c8fc178f822.png) ---

It looks like you are using fold operator.
