Measurement data from the WSP are generated when the user visits a dedicated web page (e.g. Collected Raw Measurement Data Measurement data are gathered from measurements made by mobile user devices (WiFiMon Software Probes - WSP's) and WiFiMon Hardware Probes (WHP's).

Filebeat monitors log files for new content, collects log events and forwards them to Logstash. Another component of ELK Stack is Filebeat, which is installed as an agent on the servers and is used to stream the log data.

The WiFiMon Admin uses Kibana as a web user interface and for cluster management. Raw measurement data received from multiple measurement data sources are filtered and correlated in the Logstash and stored in the cluster. Elasticsearch is a full-text, distributed NoSQL search engine which enables storing of raw measurement data, high-speed access and processing. The WiFiMon Analysis Station (WAS) uses an ELK cluster for performance measurement data processing and visualisation. Using the WiFiMon UI, they can perform queries to the Elastic ELK Cluster and get information about the performance of the wireless network.įigure 1 : WiFiMon Architectural Components The WiFiMon admin is the network administrator managing the WiFi network and the WiFiMon system. Raspberry Pi's) and placed in fixed positions within the monitored WiFi network. In addition, WiFiMon offers hardware probes (WiFiMon Hardware Probes, WHP) which are installed on small form factor hardware devices (e.g. Crowdsourced measurements are gathered from the user devices when the user visits some chosen webpage which contains WiFiMon script tags that invoke JavaScript-based measurements. WiFiMon Architectural ComponentsĪ mobile user device is any user's device connected to the WiFi network (laptop, phone, tablet.). This page describes the key components and the measurement workflow of the WiFiMon system.
