Hi I am trying to set a condition for a watch that looks at a percentile of the response time of the API. The problem is that the field I need to look at in the tree has the value of "90.0" since this is how ES returns percentile values. ![](https://us1.discourse-cdn.com/elastic/original/2X/9/9fda5eeb9ffb85e8bb81c94872ee2dab694132fd.png) I have tried all combinations even using ['90.0'] to no avail. Problem is I cannot use something like this: [note I was able to change the agg name from "1" to "nth" but cannot do the same with the percentile] ![](https://us1.discourse-cdn.com/elastic/original/2X/b/bcd9faf34841770507521038eef1dff92b7d16e5.png) How can I set this watch? I cannot find anyway, appreciate your help. ---

the below worked for me: `"input": { "search": { "request": { "search_type": "query_then_fetch", "indices": ["logstash-syslog-*"], "types": [], "body": { "size": 0, "aggs": { "percentiles": { "percentiles": { "field": "my_numeric_field", "percents": [1, 5, 25, 50, 75, 95, 99] } } } } } } }, "condition": { "script": { "inline": "if (ctx.payload.aggregations.percentiles.values[\"99.0\"] > 0) return true;return false;" } }` ---

Ali, it appears that implementing the same check using watcher [compare](https://www.elastic.co/guide/en/watcher/current/condition.html#condition-compare) is not working, one of our developer found out and it is most likely a bug. using scripting for now is a valid workaround. ---

Thank you! Do I need to enable scripting? Because it is not enabled. ---

Hi Aliostad, For the example that Antonio shared, you do need to enable scripting. However, it's easy to make the percentiles aggregation return it's results in a slightly different format that you can use with the compare condition. If you add `"keyed":true` to the percentiles aggregation, the results will come back in an array with keys and values, which are easy to parse. In fact, I demonstrated doing this in a Webinar in July 🙂 You can skip to around 30:00 to see the example an how I used it: [https://www.elastic.co/webinars/watcher-practical-alerting-for-elasticsearch](https://www.elastic.co/webinars/watcher-practical-alerting-for-elasticsearch) Hope that helps!

Awesome!! Thanks a lot. And I think you meant `"keyed":false` but I got it! Cheers ---
