When installing a new Data Collector, after specifying the Data Aggregator IP, choosing no (for multitenancy Installation) the following error is displayed:
“Could not determine hostname, there was an error determining the hostname for this System. Please contact the System Administrator to resolve this issue. “
Applies to all Versions of Performance Management released to date
The Installer cannot resolve the correct Hostname for the Data Aggregator IP
Verify that etc/hosts, /etc/sysconfig/network and /proc/sys/kernel/hostname contain the same fully qualified host name.
