Hi All,  
I am very new in ELK, I have configured the logstash config file where I have below code cnipped configurred to implement and trigger email when a threshold crossed. To get this done I used mertic but its not executing... please see below:

filter{  
...  
if "Invalid sm\_usergroups" in [message] {  
metrics {  
meter =\> ["Invalid sm\_usergroups"]  
add\_tag =\> "metric"  
}  
}

output{  
if "metric" in [tags] { // this itself is not working, after this need to implement threshold  
stdout {  
codec =\> line {  
format =\> "Output from Metric."  
}  
}  
email {  
.....  
}  
}

Please Note: I am using ELK-5.5.0, version can not be updated as already existing implementation is there in place. I have to use this version only.  
Please help.
