By default, syslog messages are exported from the devices to port 514, while NetVizura listens on the port 33514 in Linux systems and on the port 514 in Windows systems. If you use Linux systems, you need to (1) redirect syslog messages to the 33514 on NetVizura server, (2) export syslog messages to 33514 from device, or (3) change NetVizura EventLog configuration. Same applies to trap socket port.
To change NetVizura EventLog configuration go to 
> Settings > EventLog Settings > Configuration and under Service options change the Socket port values.
Checking the System
Now is a good time to check if the system is working properly.
To do so, follow these steps:
- Check if the Collection port is set properly
To see the Collection port number, go to > Settings > EventLog Settings > Configuration tab, and you will find the Service socket port field. Collection port number must match with the port number your network devices are logging events to. - Make sure data is collected
Go to Syslog/SNMP Trap > System tab. Naturally, it is required that NetVizura server and exporters have network connectivity. Check the system for warnings or errors.
Click on the Show log arrow (in the bottom right corner). Any warnings or errors will be displayed as well as the instruction to resolve them.Finally, check if the event logs are available
Go to Syslog/SNMP Trap tab. Logs should be shown on the graphs, this is a verification that the log data has been collected by the EventLog Collector.
