KBI 311316 Issue Addressed: DeviceMagic Rule Failed To Reach Device When DNS Name Is Used


Argent Advanced Technology 3.1A-1510-A and earlier


Tuesday, 1 December 2015


DeviceMagic with option ‘Test Host Device’ always reports ‘Failed to reach device xxx’ if the CMDB-X Node uses DNS name instead of IP address for Node name

However, if System Down Rule ‘NDE_PING’ runs OK with the same Node

The issue has been addressed in Argent AT 3.1A-1510-T9

Technical Background

The issue is caused by coding error

Argent for SNMP uses ICMP API to ping remote device

The API takes the IP address only

The DNS name must be resolved into IP address first

Directly passing in DNS name can result the failed ping or unpredictable status


Upgrade to Argent AT 3.1A-1510-T9 or later

For customer who cannot upgrade immediately, he can specify the alternative IP for the device in CMDB-X
