Issue/Introduction

We are trying to merge data from two collectors using the SmartStorTools merge function but it is failing:

$ ./SmartStorTools.sh merge /apm/dev/data /apm/coll1/data
Debug options:

Environment

Release : 10.7.0

Component : Introscope

Cause

Whilst the source and destination folders specified in the command arguments were present in the environment they were not the location of the .data files. The IntroscopeEnterpriseManager.properties file had been modified and a custom location below the data folder had been specified therefore the .data files were in that location

introscope.enterprisemanager.smartstor.directory=data/stor

 

(default value is introscope.enterprisemanager.smartstor.directory=data)

Resolution

Re-executed the command to specify location of Smartstor data files correctly

$ ./SmartStorTools.sh merge /apm/dev/data/stor /apm/coll1/data/stor
