Description
What we need
Taranta has a new widget (Log Viewer) that let's the user of a running dashboard to view, filter, search log messages sent by devices. Filtering can be done for example by log level, by device name. Searching can be done by free text (as a ctrl-F done in a browser - but scoped on log messages only, not the entire dashboard).
When configuring the widget, the dashboard editor user selects the devices whose logs are to be shown. Ideally the default devices will be all the devices used by the dashboard. Configuration is also related to the refresh rate of the widget, application of available filters (that need to be predefined in Kibana), size of the scollable buffer (eg 2000 lines, even though only 100 are shown, in a scrollable panel). Another configuration option is the format of the line (sequence of log fields to be displayed: eg <timestamp in isoformat, device, level, message>).
As mentioned above filters can be activated that would allow displaying only lines that have been emitted by given sources, at or above given log levels, within certain datetime ranges.
Given a certain configuration, when the widget is run it interacts with Kibana and collects relevant info. With the specified refresh rate, the widget updates its space with new lines as they are made available by any of the source devices, possibly by scrolling the text so that the most recent lines are always visible. A scrollbar can be used by the user to view previous messages (up to a maximum size of the log buffer). Text is filtered, processed and formatted based on active filters.
The widget comes with a predefined set of filters (eg. filter based on log levels, on source devices, on datetime ranges) that can be activated by any user.
(This description comes after reading the document that CREAM produced at the end of work for SP-2358, and is based on the analysis of Pro's and Con's that Giorgio did in the attached document).
