Troubleshooting

Check Server Resources

Ensure that the server running the Wazuh dashboard has sufficient CPU, memory, and disk space. Inadequate resources can delay the startup process.

Check Wazuh Logs

Wazuh indexer

$ cat /var/log/wazuh-indexer/wazuh-cluster.log | grep -i -E "error|warn"

Wazuh manager

$ cat /var/log/filebeat/filebeat | grep -i -E "error|warn"

Wazuh dashboard

$ journalctl -u wazuh-dashboard
$ cat /usr/share/wazuh-dashboard/data/wazuh/logs/wazuhapp.log | grep -i -E "error|warn"

Service Status

Verify that all necessary Wazuh services are running correctly. You can use the following commands to check the status:

1)
$ systemctl status wazuh-manager 
or 
$ systemctl status wazuh-manager|grep Active

2)
$ systemctl status wazuh-dashboard 
or 
$ systemctl status wazuh-dashboard|grep Active

3)
$ systemctl status wazuh-indexer 
or 
$ systemctl status wazuh-indexer|grep Active

4)
$ systemctl status filebeat 
or 
$ systemctl status filebeat|grep Active

5)
$ filebeat test output

Another common problem.

Wazuh-indexer may time out when starting the service and Wazuh-dashboard may not start. This can happen if the service does not start in the time Linux expects it to. We can extend this time with the following steps:

$ systemctl edit wazuh-indexer

and add the following lines

[Service]  
TimeoutStartSec=180  

Save the file and execute

$ systemctl daemon-reload  
$ systemctl restart wazuh-indexer  
$ systemctl restart wazuh-dashboard
