Technical Tip: How to fix Collector IP shows IPv6 instead of IPv4 in Collector health

When there is no IPv6 configured on the collector, Admin -> Health -> Collector Health shows the IPv6 address of the collector instead of the IPv4 address.

The below-mentioned steps can be followed to correct this behavior such that the IPv4 address is shown correctly:

• Take a snapshot of the collector at the Hypervisor level.
• Use the below commands to disable the IPv6 in Collector:

sysctl -w net.ipv6.conf.all.disable_ipv6=1

sysctl -w net.ipv6.conf.default.disable_ipv6=1

Apply the changes:

# sudo sysctl -p

• Once done, restart phMonitor in the collector:

# killall -9 phMonitor

• Once phMonitor is up on the collector, refresh the Collector health page after a few minutes and check if the Collector IP shows with an IPv4 address.
