Hi All,  
We receive json lines from logs.  
would need to aggregate this json lines to json Array  
Sample:  
{  
"source" : "Request"  
"target": "Request\_parsed"  
}  
{  
"source" : "Request1"  
"target": "Request\_parsed1"  
}

Output  
[  
{  
"output": {  
"source": "Request",  
"target": "Request\_parsed"  
}  
},  
{  
"output": {  
"source": "Request1",  
"target": "Request\_parsed1"  
}  
}  
]

through mutate filter can add the field , would need to merge all fields.

You can combine events using an aggregate filter.
