SNMP Collector Error

We have standard licence for flowcoll as well as snmpcoll. Based on the snmp configuration documentaion I configured and start the snmpcoll service, I didn’t get any errors in log file unfortunately I can’t see any data in indices also I have attached the logfile screenshot could you please help me

Can you check your configuration and ensure logging is set to true and then restart the collector and attach the logs from /var/log/elastiflow/snmpcoll/
