Hi First off, ntopng is a great piece of software. I am working in performance team in Oracle and researching whether we can use it to monitor network usage of VMs on nimbula clusters.
Needed some help regarding the same. I have installed ntopng and redis server successfully on one of my VMs (2.6.39-400.109.6.el6uek.x86_64) but not able to start ntopng The error that I am facing is as follows [root@ucf2b-docs-psr0427-ms1 bin]# ./ntopng 30/Apr/2015 10:48:53 [Ntop.cpp:779] Setting local networks to 192.168.0.0/16,172.16.0.0/12,10.0.0.0/8,127.0.0.0/8,0.0.0.0/32,224.0.0.0/8,239.0.0.0/8,255.255.255.255/32,127.0.0.0/8 30/Apr/2015 10:48:53 [Redis.cpp:93] Successfully connected to Redis 127.0.0.1:6379@0 30/Apr/2015 10:48:54 [main.cpp:201] ERROR: Startup error: missing super-user privileges ?
