Ok, the execute watch API output would be great, but we can also get some watch history output,
can you run (and likely put it into a gist, as it will contain 10 executions which hopefully contain stack traces)
GET .watcher-history-*/_search
{
"query": {
"bool": {
"filter": [
{
"term": {
"watch_id": "ml-cpu"
}
}
]
}
},
"sort": [
{
"trigger_event.triggered_time": {
"order": "desc"
}
}
]
}
