Introduction

NetFlow Optimizer (NFO) software keeps track of its activity by logging to various files in $NFO_HOME/logs (NFO_HOME default is /opt/flowintegrator). You can also see its health on the Status page. This page shows input / output statistics, length of various queues, and drop counts.

The NFO internal log files are rolled based on size. Ten last files are kept in $NFO_HOME/logs/bak directory. You can change the default log rotation size and the number of “bak” files to keep by editing $NFO_HOME/server/etc/server.cfg.

You can download logs from NFO by going to Tracing and Configuration on the left navigation bar, and clicking on Download logs button.
