-Install package 'redhat-lsb-core' to provide command 'lsb_release'? [N/y] ----
During every polling the Applications Manager executes the commands to fetch the data from the remote server by establishing an CLI based SSH session, when it executes the command if we are getting an response from the server like above this will interrupt the data collector threads hence resulting in data collection failure
Solution:
yum install redhat-lsb-core
After installing this package on the target Linux servers check if the data collection is successful and if you notice any issues you can share the support information file with the applications manager technical support team (appmanager-support@manageengine.com)
