I need help in parsing a nested array data  
'''  
"abc" =\> [  
[0] {  
"obj" =\> "78",  
"val" =\> "0/100",  
"name" =\> "xyx",  
"email" =\> "[xyz@gmail.com](mailto:xyz@gmail.com)"  
},  
[1] {  
"obj" =\> "78",  
"val" =\> "0/100",  
"name" =\> "xyx",  
"email" =\> "[xyz@gmail.com](mailto:xyz@gmail.com)"  
}  
]

'''

'''  
mutate {  
split =\> ["abc", "."]  
add\_field =\> { "shortHostname" =\> "%{abc}" }  
add\_field =\> { "new\_filed" =\> "%{abc[0][obj]}" }

mutate+split is used to break a string into an array. If you want to break an array into multiple events then use a split filter instead.
