Hello!
I'd appreciate for any help, can't figure it by myself for a long time.
I have a quite simple watcher, like this:
{
"trigger": {
"schedule": {
"interval": "5m"
}
},
"input": {
"search": {
"request": {
"search_type": "query_then_fetch",
"indices": [
"metricbeat-*"
],
"rest_total_hits_as_int": true,
"body": {
"size": 0,
"query": {
"bool": {
"must": [
{
"exists": {
"field": "system.load.5"
}
},
{
"range": {
"@timestamp": {
"gte": "{{ctx.trigger.scheduled_time}}||-2m",
"lte": "{{ctx.trigger.scheduled_time}}",
"format": "strict_date_optional_time||epoch_millis"
}
}
}
]
}
},
"aggs": {
"host": {
"terms": {
"field": "agent.id",
"size": 10,
"order": {
"load_5": "desc"
}
},
"aggs": {
"load_1": {
"max": {
"field": "system.load.1"
}
},
"load_5": {
"max": {
"field": "system.load.5"
}
},
"load_15": {
"max": {
"field": "system.load.15"
}
},
"total": {
"max": {
"field": "system.cpu.total.pct"
}
}
}
}
}
}
}
}
},
"condition": {
"script": "return ctx.payload.aggregations.host.buckets.0.load_5.value > 1 || ctx.payload.aggregations.host.buckets.0.load_15.value > 1 "
},
"actions": {
"slack_alert_1": {
"condition": {
"script": "return ctx.payload.aggregations.host.buckets.0.load_5.value > 1 || ctx.payload.aggregations.host.buckets.0.load_15.value > 1 "
},
"slack": {
"message": {
"from": "Watcher. Server -> {{ctx.payload.aggregations.host.buckets.0.key}}",
"attachments": [
{
"color": "warning",
"title": "High CPU Usage Alert!",
"text": "INFO \n LOAD 1 - {{ctx.payload.aggregations.host.buckets.0.load_1.value}} | LOAD 5 - {{ctx.payload.aggregations.host.buckets.0.load_5.value}} | LOAD 15 - {{ctx.payload.aggregations.host.buckets.0.load_15.value}} \n CPU Usage - {{ctx.payload.aggregations.host.buckets.0.total.value}}%"
}
]
}
}
}
}
}
The return output is:

}
}
},
I can't understand, why it returns "null" values of "total" (system.cpu.total.pct).
"total" : {
"value" : null
},
But when I look at same metric at "Metrics Explorer" I can see values and grafhs.
I use Elastic Cloud with Kibana 7.5.1 and Metricbeat 7.5.1 on hosts via docker.
