Oups... I missed something in log file. I noticed these lines, when restarting the service monitorix :
Sun May 11 19:12:56 2014 - Starting Monitorix version 3.5.1 (pid 29323). iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. iptables: No chain/target/match by that name. So, it seems that there is an issue with iptables... I've flushed all iptables rules before restarting moniorix.
