With Elasticsearch/Kibana on master, when running metricbeat with the system module active, opening the Host Overview dashboard leads to an error

"reason":"field expansion matches too many fields, limit: 1024, got: 1030"

The full error, as well as the metricbeat configuration I used can be found here: https://gist.github.com/beniwohli/bb1bfe63ed02480d08025a444d157376
