This introduction takes you on a short tour showing some aspects of Icinga Web. It is not complete so there will be things which aren't covered. We're working on this.
If you followed the quickstart guides (IDOUtils and Icinga Web) then please open your browser and enter http://<icinga server>/icinga-web. You will get the login screen
You should be able to login using "root" and "password". This will take you to an overview page showing the state of the hosts and services being monitored
Main Screen
This is where everything comes together: You can drag and drop new windows over here resulting in a new opened tab. The views are customizable for the current user (they remain persistent) by dragging the column heading to the new place. Rightclicking on the heading allows to change the sort order or to hide columns. Selected search results will be opened here too, next to opening available cronks.
Status Cronk
The status cronk shows host and service counters for their respective states. If count is zero, the colour remains grey. Clicking on states opens a new tab in the main view showing the current clicked state only. Next to that, general process information is provided, just as
Hosts|Services (active/passive)
Host|Service execution time (min/avg/max)
Host|Services latency (min/avg/max)
Top menu
The top menu consists of general information about Icinga and the administration items for users, groups and logs. On the top right, you can see the user currently logged in and edit its preferences or log out of Icinga Web.
Left menu
In the left (also hideable) menu you can select among different widgets (we call them "cronks"). You can either doubleclick on each cronk or drag it with the cursor into the main view. The categories are separated into
"Data" for getting status, historical and configuration data
"Tactical Overview" keeps general charts and customized ones (custom variables)
"Misc" contains several useful cronks, just as iframe for external websites or the 1,2,3 columns for main view
Search
The search form shows results while typing. The results will be shown in a separate inlay window. By clicking/selecting the results, a new tab in the main view opens with more information. Please note that the search is currently case sensitive ("ping" vs. "PING").
Log
At the bottom, the current Icinga log is being shown. The log is refreshed automatically and can be hidden in order to allocate more space for the main view.
Cronks and Views
Icinga Web allows to open different cronks in order to view data, set filters for different views, send commands. The following list summarizes the possibilities in general (several Cronks can provide more, like sending commands).
Manual Refresh
Settings
Enable/Disable Auto-Refresh
Get this <item> by url
Filter
Modify/Remove
Commands
There are different commands available (check the chapter External Commands for more information on commands). Select the items which should be affected and then select the command to be executed.
Host Commands
Service Commands
Filters
Icinga Web allows to set filters and create customized views which can be saved as own persistent cronk too. First, select "Filter" and "Modify". Add a restriction selected from the dropdown menu (this differs for various cronks). You can set more restrictions by repeating this procedure.
Afterwards, specify on which condition the filter should match on the selected restriction (contain, does not contain, is, is not) and add a value into the form. Proposals are shown while you are typing.
Apply the filter to the current cronk. If needed, you can modify the filter afterwards and add/remove restrictions and conditions. An active filter is marked red.
Administration
Enter the administration panel by selecting "Admin" from the top menu, and select "Users", "Groups" or "Logs".
Users
You can add, remove and edit users.
Doubleclick a user to open a new inlay window which lets you edit very detailed options. The same options apply when adding a new user. You can modify the size by dragging the cursor in the corners.
General information
Change password (and optional AuthKey for API)
Permissions e.g. which group membership
Principals for special roles
Groups
You can add, remove and edit groups. You can also modify group inheritance within the group tree on the right side.
Doubleclick a group to open a new inlay window which lets you edit very detailed options. The same options apply when adding a new group. You can modify the size by dragging the cursor in the corners.
General information + Permissions (which users are part of this group)

Within the user and group administration panel, you can add/remove/edit principals. You can see default available principals in the picture:
