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.
Due to constant development some things change over time resulting in different appearance and additional options. Please have a look at the current version 1.10.
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
Top menu
The top menu consists of general information about Icinga and the administration items for users, groups, logs, and tasks. The live-search is accessible using the field next to the magnifying glass. On the top right, you can see the user currently logged in and edit its preferences or log out of Icinga Web.
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. The search starts at the beginning of the string but you can use wildcards as well.
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 selected state only. Next to that, the number and state of the Icinga instances is shown. In the remaining space general process information is provided, just as
Hosts|Services (active/passive)
Host|Service execution time (min/avg/max)
Host|Services latency (min/avg/max)
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
"Tactical Overview" keeps general charts and customized ones (custom variables)
"Reporting" enables to create reports
"Misc" contains several useful cronks, just as iframes for external websites or the 1,2,3 columns for main view and links to the documentation.
Within the settings menu, you can switch back to the old view with the bigger icons. Within userpreferences.xml
config file you may set a global default value.
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.
Host Status
The HostStatus view shows the host status and below the number of warnings/critical of the services attached to the host.
Use the expanded view to change to ServiceStatus- view for this host, to look for history informations or to locate the host in statusmap. If you use PNP4Nagios you can also switch to the performance data.
On the left you will see the expander icon. Clicking on it will open a bar below the icon.
Right-clicking on any of the new icons and selecting "Move into grid" will move the appropriate icon into the grid.
Selecting the new icon opens a small window or it will create a new tab showing the desired information.
Clicking on "Setting" and selecting "Reset grid action icons" will remove the inserted icons restoring the default view.
Host Object Informations
Use Details to see more detailed object informations like status, relations and external references.
Service Status
The ServiceStatus view shows all services for each host.
Service Object Informations
Use the expanded view to look at the service object and history informations, the host object informations or to change to HostStatus view.
Hostgroup Status
The hostgroup view will show the status and the number of hosts grouped by hostgroup.
Log
The log view shows the log messages.
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 cronks, too. First, select "View Filter". On the left side on top of the cronk menu, you'll see the attributes and condition to select at the bottom. At the top the current selected filter is shown.
Afterwards, specify on which condition the filter should match by moving the conditions and selected attributes using drag and drop.
Once you have dropped an attribute filter onto a condition, you can specify its values (depending on the attribute, the screenshot shows only the state selection). Click "Add filter" when done.
The active filter now shows only the filtered entries.
You can combine multiple filters of the same type at once, as well as combine conditions. The example below shows an OR condition for the filter on critical and warning states.
Enter the administration panel by selecting "Admin" from the top menu, and select "Users", "Groups", "Logs", or "Tasks".
Users
You can add, remove and edit users. You can also search for 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
Roles
You can add, remove and edit roles. You can also modify role inheritance within the group tree in the lower half. You can also search for groups.
Doubleclick a role to activate the window on the right side which lets you edit very detailed options (see below). The same options apply when adding a new role. You can modify the size by dragging the cursor in the corners.
Logs
You can view several logs here, in order to catch up on possible errors.
Tasks
Several changes require clearing the cache. Instead of using the command line you can issue the command via the "Tasks" menu.
