Hi All, I am storing a java map to my database which is in this form  
{id=sampleid,name=samplename}  
actual data is larger but I want to extract individual fields(like id and name) from above log. I tried using json filter but it is not working is there any way to do it?

A kv filter will be able to parse the particular example you gave. You may want to use a grok filter to extract the key/value pairs inbetween the curly braces (a mutate filter's gsub option would also work).
