I have a field 'brief' in the below format.

"brief": [  
{rx-usage: 0.0,  
tx-stats: {tx-errors: 0, tx-bytes: 3597278194, tx-bps: 1808, tx-pps: 3, tx-packets: 8620093},  
name: vni-0/0, host-inf: eth1, if-oper-status: up,  
rx-stats: {rx-packets: 1088458, rx-pps: 2, rx-bps: 1392, rx-errors: 0, rx-bytes: 67069272},  
tx-usage: 0.0},

{rx-usage: 0.0,  
tx-stats: {tx-errors: 0, tx-bytes: 2105140374, tx-bps: 14464, tx-pps: 11, tx-packets: 12370683},  
name: vni-0/1, host-inf: eth2, if-oper-status: up,  
rx-stats: {rx-packets: 19948899, rx-pps: 9, rx-bps: 12760, rx-errors: 0, rx-bytes: 6312190688}, tx-usage: 0.0}  
]

I try to have the following.

"brief"=[  
{rx-usage: 0.0,  
tx-stats: {tx-errors: 0, tx-bytes: 3597278194, tx-bps: 1808, tx-pps: 3, tx-packets: 8620093},  
name: vni-0/0, host-inf: eth1, if-oper-status: up,  
rx-stats: {rx-packets: 1088458, rx-pps: 2, rx-bps: 1392, rx-errors: 0, rx-bytes: 67069272},  
tx-usage: 0.0}]

"brief"=[  
{rx-usage: 0.0,  
tx-stats: {tx-errors: 0, tx-bytes: 3597278194, tx-bps: 1808, tx-pps: 3, tx-packets: 8620093},  
name: vni-0/0, host-inf: eth1, if-oper-status: up,  
rx-stats: {rx-packets: 1088458, rx-pps: 2, rx-bps: 1392, rx-errors: 0, rx-bytes: 67069272},  
tx-usage: 0.0}]

If you are saying you want to split an array into one event for each value in the array then use a [split](https://www.elastic.co/guide/en/logstash/current/plugins-filters-split.html) filter.

@badger when I use split filter, it is saying "Only String and Array types are splittable. field:[brief] is of type = NilClass"

split{  
field =\> "[brief]"  
}

That is telling you that the field does not exist on some events.
