PRTG monitoring - Sensor Syslog receiver not receiving all data

[Barry Landon]

PRTG system in place running other sensors on the same host, which are working.  Ive added syslog receiver sensor and receiving PRTG data from switch that increases drops, errors and warning stats that disappear after a few minutes.  Within messages panel  log entries are being logged but only timestamp and source IP address are correctly populated.  Messages column displays 0��
0 ���


00.� and the rest of the columns, timestamp severity etc are blank.  Overall sensor is connected but details from system logging are either being misinterpreted at PRTG or not being received.  

No packets are being dropped at the firewall towards PRTG.
