The third tab shown within the 'My System' tab is the 'Web' tab:
The 'Web' tab allows for the confirmation of various items including the standard refresh interval in the GUI (30 seconds by default), and how much the audit log data is retained for. There is also the option for setting downtime on deleted hosts; this means that if you delete a host but don't reload immediately, you won't get notifications when the host is presumably taken offline and service checks turn critical, etc. Opsview Monitor has automatically scheduled an indefinite period of downtime on deleted host which will last until a reload has been applied (and thus the host is removed entirely).
The second half the 'Web' tab is the Wiki integration section. Within this section, you can choose to integrate your Opsview Monitor software with an existing wiki, such as Dokuwiki, Confluence, etc.
You can simply add a customised URL at a Host Group, Host or Service Check level ' such as http://mywiki.company.com/listofallhosts?=$HOSTNAME$. When this link is clicked in the menu for a given Host, it will load the URL up, filtered on the hostname i.e. http://mywiki.company.com/listofallhosts?=opsview. The option to load this URL is found in the 'Notes' tab within 'Investigate' for Hosts/Service Checks, and the contextual 'Notes' menu option for a Host Group:
