Aside from being beneficial from a visualisation and analytical perspective, Hashtags can be used to control what Users can see when they log-in to Opsview Monitor.
This means you can navigate through ‘Settings > Hosts’ and ‘Settings > Service Checks’, tag objects (Hosts/Service Checks) with our previously created ‘superimportant’ Hashtag, and then create a Role that gives Users access to only view/configure (depending on the configuration within the Role) objects tagged with ‘SUPERIMPORTANT’. When Users who are members of the new Role log in, they will only be able to view/configure objects that were appropriately tagged.
This is a really nice way of configuring access control; it means once you have configured a new Role to restrict User’s visibility to just objects tagged with ‘SUPERIMPORTANT’, you can grant visibility to new objects (i.e. newly added Hosts) simply by assigning them the Hashtag ‘SUPERIMPORTANT’.
