Counters are for continuous incrementing values such as bytes sent and received.Gauge are for things like the number of active flows, or active hosts.Gauges and counters are the two types of timeseries exported by ntopng: The query builder helps constructing the classical SELECT-FROM-WHERE clauses to pick the right data.ĭifferent queries need to be constructed, depending on whether a gauge or a counter is being charted. Timeseries data are added to panels using the Grafana query builder. Now that Grafana is properly set up to extract timeseries data from InfluxDB, new panels with ntopng timeseries data can be added to dashboard panels. Adding Grafana Dashboards panels with ntopng data NOTE: The Grafana ntopng plugin datasource is outdated and should not be used. Then, it is enough to specify InfluxDB connection parameters.Ĭlicking on “Save & Test” will automatically test the connection and save it. To create the datasource, pick the Datasources entry under the Grafana configuration menu, and add a new datasource of type InfluxDB. The same InfluxDB connection parameters specified above to configure ntopng can be used also to create a Grafana InfluxDB datasource. Once preferences are saved, ntopng will start exporting timeseries data to InfluxDB.Ĭonfiguring the Grafana InfluxDB Datasource Then, it suffices to configure InfluxDB connection parameters. To configure ntopng to export timeseries data to InfluxDB, visit the ntopng Timeseries preferences page, and pick InfluxDB as driver. Configuring ntopng to Export Timeseries Data to InfluxDB This post aims at covering the topics above to serve as reference for those who want to create Grafana dashboards. Adding Grafana Dashboards panels with ntopng data.Configuring the Grafana InfluxDB datasource to extract timeseries data from InfluxDB.Configuring ntopng to export timeseries data to InfluxDB.For more information, see the chapter Alerts Dashboard.Creating Grafana dashboards out of ntopng data basically boils down to: For more information, see the chapter Flows Dashboard.Įngaged Alerts, Past Alerts, Flow Alerts: tables of active alerts, past alerts and flow alerts. In the application table, the application names are linked and lead to an ntopng page with detailed information.įlows: Table of the data flows that have the selected host as a start or end point. The layer 7 applications are determined by a deep packet inspection. The graphic elements can be filtered by clicking on them.Īpps: Amount of traffic divided by applications and summarised categories. Peers: An overview of the most frequently contacted peers (meaning partners) and the most frequently used applications - as graphics and a table. Ports: Traffic statistics grouped by client and server ports The most frequently used flags are SYN (synchronisation), ACK (acknowledgement), FIN (finish) and RST (reset). Flags indicate a certain state of the connection or provide additional information. Packets: Distribution of flags in TCP connections. Traffic: Information on the layer 4 protocol (TCP and UDP) for an overview as a pie chart and detailed as a table Host: Basic information for the host and a summary of the most important information from the other tabs By the way, the default user account of ntopng is called admin and is assigned to the user group Administrator. Checkmk authenticates with the ntopng server using these credentials via the REST API.
#Ntopng grafana password#
Name and password of a user account of the ntopng user group Administrator ( ntopng Admin User). The name and password of the ntopng user account are stored in plain text in the Checkmk site, as the access data must be transmitted unencrypted via the REST API to the ntopng server.
The connection between Checkmk and ntopng should only be made via HTTPS. The port is specified when ntopng is started. The number of the TCP port ( Port number), over which ntopng can be reached. The name or IP address ( Host Address) of the ntopng server You must enter this information into Checkmk as ntopng connection parameters: Parameter First collect the following information about the ntopng target system you want to connect to Checkmk.
