Two questions:

1. Does below elastalert rule is correct to get a cumulative data in "system.network.in.dropped"?
2. Can we use two fields in compare\_key? we tried but did not work means when have both fields then do not send a elastalert.  
Example,  
compare\_key: ["system.network.in.dropped OR "system.network.out.dropped"]

Using below code:  
name: Metricbeat - [Net]In/Out Network Packet Dropped  
type: change

es\_host: 10.1.1.20  
es\_port: 9200

index: metricbeat-\*

# How often ElastAlert will query elasticsearch

run\_every:  
minutes: 2

# ElastAlert will buffer results from the most recent

buffer\_time:  
minutes: 15

#bucket\_interval:

# minutes: 15

realert:  
minutes: 10

compare\_key: "system.network.in.dropped"

ignore\_null: true

query\_key: "system.network.name"  
doc\_type: \_doc

sync\_bucket\_interval: true

filter:

- query:  
query\_string:  
query: "metricset.name:network AND host.name:test124"
- query:  
query\_string:  
query: "system.network.in.dropped:(\>0) OR system.network.out.dropped:(\>0)"

hi @shilpa,

this is probably the wrong forum for an ElastAlert question. The project is hosted here: [https://github.com/Yelp/elastalert/issues](https://github.com/Yelp/elastalert/issues)
