Hi Team,

I am working on a watcher alert which will send an alert when the last aggregated bucket doc\_count crossed certain value. Could you please help me how to achieve it to compare the last sub backets doc\_count value. I have used array\_compare in the wacther condition as below.

My aggregation:  
"aggs": {  
"dc\_aggs": {  
"terms": {  
"field": "dc"  
},  
"aggs": {  
"rule\_aggs": {  
"terms": {  
"field": "rule"  
},  
"aggs": {  
"alertid\_aggs": {  
"terms": {  
"field": "alertid"  
},  
"aggs": {  
"primary\_page\_aggs": {  
"terms": {  
"field": "primary\_page"  
},  
"aggs": {  
"activity\_aggs": {  
"terms": {  
"field": "activity"  
},  
"aggs": {  
"last\_input\_aggs": {  
"terms": {  
"field": "last\_input"  
},  
"aggs": {  
"last\_step": {  
"terms": {  
"field": "last\_step"  
},  
"aggs": {  
"stack\_aggs": {  
"terms": {  
"field": "stack"  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}  
}

I want to compare the count of last sub bucket "stack\_aggs" doc\_count \> some value. is it possible. I have tried like below but it is not working. Please help me how can i do it.

"condition": {  
"array\_compare": {  
"ctx.payload.aggregations.dc\_aggs.buckets.rule\_aggs.buckets.alertid\_aggs.buckets.primary\_page\_aggs.buckets.activity\_aggs.buckets.last\_input\_aggs.buckets.last\_step.buckets.stack\_aggs.buckets": {  
"path": "doc\_count",  
"gt": {  
"value": 170,  
"quantifier": "some"  
}  
}  
}  
}
