This document provides troubleshooting guidance for common Kibana issues encountered during installation, configuration, and operation in Relativity environments.
This guide assumes a default Kibana installation path of C:\elastic\kibana
. Adjust paths according to your actual installation directory.
The following troubleshooting steps apply only if Kibana was set up as a Windows service (e.g., using NSSM or a similar tool). If you did not install Kibana as a Windows service, you must ensure that kibana.bat
is running in a command prompt or as a scheduled task.
Symptoms:
Troubleshooting Steps:
Check Service Status and Configuration:
Get-Service -Name kibana
Status Name DisplayName
------ ---- -----------
Running kibana Kibana
Get-CimInstance -ClassName Win32_Service -Filter "Name='kibana'" | Select-Object Name, State, StartMode, StartName
Check Kibana Logs:
C:\elastic\kibana\logs\
kibana.log
) for error messages.Unable to connect to Elasticsearch at https://<host or ip address>:9200
).Start Service Manually:

Generate Encryption Keys:
cd C:\elastic\kibana\bin
.\kibana-encryption-keys.bat generate
xpack.encryptedSavedObjects.encryptionKey: "<randomly-generated-key-1>"
xpack.reporting.encryptionKey: "<randomly-generated-key-2>"
xpack.security.encryptionKey: "<randomly-generated-key-3>"
Configure Required Encryption Keys in kibana.yml:
C:\elastic\kibana\config\kibana.yml

Troubleshooting Steps:
Check Kibana Status:
curl.exe -k -u <username>:<password> -X GET "http://<hostname_or_ip>:5601/api/status"
{

"version": {
"number": "8.x.x"
},

Validate YAML syntax
C:\elastic\kibana\bin\kibana.bat
# There is no built-in --validate-config option in Kibana 8.x.
# Configuration is validated when Kibana starts.
# If there are errors in kibana.yml, they will be shown in the console output and Kibana will fail to start.
Symptoms:
