It is very similar to the popular top Unix command and it is a network traffic probe that will show you the network usage. ![]() On systemd-based systems, such logsĬan be accessed also using the journalctl facility.NTop is a network traffic probe that will show you the network usage. To process or see all ntopng-generated Syslog logs, the file /var/log/ntopng.log can be accessed directly. This behavior can be changed by editing or removing /etc/rsyslog.d/nf. Packaged versions of ntopng install a rule in /etc/rsyslog.d/nf to dump flows and all other ntopng-generated Syslog logs to /var/log/ntopng.log. The official Curator tool from Elastic can be used to manage and rotate Indexes created by ntopngĪccording to the user preferences and requirements. Index types can be used to differentiate instances. By default, ntopng creates one daily index Ntopng will create Indexes and Mapping automatically on startup with no action required.Įach time the index name changes, a new Index is created. Note this action requires full admin rights on theĬluster in order to be performed successfully. This is achieved by using a mapping template for ntop types,Īutomatically inserted by the application at startup. Mapping is required for Elasticsearch to correctly interpret all fields produced by ntopng, specifically thoseĬontaining IP and Geo Location data. Index mapping defines the multiple supported types. More primary shards and can have zero or more replica shards distributed across nodes of a cluster. An index is a logical namespace which maps to one or Indexes are like ‘databases’ in a RDBMS terms. These settings are effective for all databases.Įs ntopng ntopng -% Y.
