 ### Finding your data
 
 If all goes well, you should see your metric data  in the Jarvis metrics list (Geneva INT (https://jarvis-west-int.cloudapp.net/) -> Manage ->  Metrics) under the account and namespace you specified in CLUSTER_MDM_ACCOUNT and CLUSTER_MDM_NAMESPACE and also be available is the dashboard settings.

+### Injecting Test Data into Geneva INT
+
+Once your monitor code is done you will want to create pre-aggregates, dashboards and alert on the Geneva side and test with a variety of data.
+Your end-2-end testing with real cluster will generate some data and cover many test scenarios, but if that's not feasible or too time-consuming you can inject data directly into the Genava mdm container via the socat/ssh network chain.
+
+An example metric script is shown below, you can connect it to 
+
+
+````
+myscript.sh | socat TCP-CONNECT:127.0.0.1:12345 - 
+````
+or 
+````
+myscript.sh | socat UNIX-CONNECT:$SOCKETFILE - 
+````
+(see above of the $SOCKETFILE )
 
 
 
+#### Sample metric script

+# example metric 
+CLUSTER="< your testcluster example name>"
