Hi,

I've an index with host name, host state and timestamp and , message fields, I want to use watcher to send an alert when a host is down. I can do that using the below watcher.

PUT \_xpack/watcher/watch/log\_error\_watch  
{  
"trigger" : { "schedule" : { "interval" : "10s" }},  
"input" : {  
"search" : {  
"request" : {  
"indices" : ["logs"],  
"body" : {  
"query" : {  
"match" : { "message": "DOWN" }  
}  
}  
}  
}  
},  
"condition" : {  
"compare" : { "ctx.payload.hits.total" : { "gt" : 0 }}  
},  
"actions" : {  
"log\_error" : {  
"logging" : {  
"text" : "Found {{ctx.payload.hits.total}} errors in the logs"  
}  
}  
}  
}

But I want to alert with the name of the host which is DOWN as well. How do I do that?

Thanks,

---
