Troubleshooting Tip: ADMIN -> Health -> Collector Health showing blank IP for upgraded collectors

Follow these steps to resolve the issue where the collector IP is no longer visible under the collector health GUI page after upgrading collectors to v7.4.X:

Note: This change should be made on every collector that is experiencing the issue.

1. Take a backup of the file /opt/phoenix/config/phoenix_config.txt on the Collector node.

cp -a /opt/phoenix/config/phoenix_config.txt /opt/phoenix/config/phoenix_config.txt_bak

2. Modify the file and add the IP in the value of the parameter FSIEM_IP= using the command (replace Collector_IP with the collector IP before running the command).

sed -i 's/^FSIEM_IP=$/FSIEM_IP=Collector_IP/' /opt/phoenix/config/phoenix_config.txt

3. Restart phMonitor on the collector using the command.

killall -9 phMonitor

4. Verify the phMonitor process is up.

phstatus

5. Verify IP visible for the collector in ADMIN -> Health -> Collector Health.
