Geomap creates maps to help to visualise the locations of objects and the links between objects in geographically diverse systems. Location and links are attributes added to objects in OP5 Monitor, and the map tiles used to render the map are downloaded from the specified geographic data service.
The Geomap page (Monitor > Geomap) provides a visualisation of object locations and links.
There are two main parts of Geomap:
- Geomap options menu.
- Map area.
The Geomap options menu is located in the right hand side of the OP5 Monitor toolbar, and clicking on it will open a drop down menu with links to set the mode and open Geomap settings.
The Map area takes up the lower part of the page, and it works like most mapping webpages. The default geographic data service is Google Maps and the map controls are imported from there.
There are three entries in the Geomap options menu:
- Edit mode.
- View mode (Default mode).
Edit mode allows locations and links to be added to the map or removed from the map. Locations do need to exist before links can be created. Edit mode also allows has a search bar which allows locations to be located via search term.
The search function returns inconsistent results, and the Map area isn't automatically adjusted to include the
search results. To see all of the results, the Map area may need to be zoomed out.
View mode is the default mode for Geomap. When in View mode, the map cannot be edited.
Locations and links can be clicked on to bring up an information balloon which contains hypertext links back to the associated objects, and the map can be scrolled around and zoom level changed to get more or less information.
Settings opens a dialog box where the geographic data provider can be set, with various provider specific options, and the refresh rate can be changed. The refresh rate is displayed in seconds. The screenshots shows refresh rates of 10 seconds and 290 seconds (4 minutes).
There are two basic settings, Provider and Geomap refresh rate, and a third setting which is dependent on the Provider setting. There are three geographic data service providers available in Geomap:
- Google Maps (Default).
Google Maps is the default geographic data service for Geomap. Out-of-the-box OP5 Monitor will use data from Google Maps, and an API key can be entered into the Google Maps API Key field to allow utilisation of addition features of the Google Maps API.
CloudMade can be set as the data source by selecting it as the data provider from the Provider drop down menu, and when set as the data provider, the CloudMade key will appear to allow a CloudMade key to be entered.
OpenStreetMap is the final option in the Provider drop down menu.
Real-time information on a Geomap client requires the client to have Internet access. By default, the client will need to download mapping tiles from one of the mapping services, and it will then use the downloaded tiles to render the map. It is possible to use pre-rendered maps if an Internet connection is not available to the client, but the process to enable this is covered elsewhere.
Geomap refresh rate sets the interval, in seconds, between data refreshes. A stock install of OP5 Monitor sets the refresh interval to 10 seconds.
- Hover over the Monitor menu entry in the OP5 Monitor Toolbar to expand it.
- Click Geomap to open the Geomap Page. (Red box in the screenshot)
Before Geomap is useful you have to add locations to the map. Each location can be associated with an object. The following object types can be used:
- Host Group.
- Service Group.
Here we will add a new location. First we need to locate where on the map we want to put the location. Then we save the location with some basic settings.
- Open up the Geomap from the monitoring menu.
- Click on edit in the upper left corner, just above the map.
- Double click on the map to place your location.
- A bubble will appear on the location, select Add location:
- Click on Save to create the location.
Enter the variables for this locations and select type, then the object you want to link to this location. You can also enter the exact latitude and longitude here:
When you have added a couple of locations to your Geomap you might want to add a link between them. This can easily be done by associating a service to a so called link object.
Here we will use two locations called:
The locations listed above are associated with one host each. Now we will add a link between the two locations and associate it with a service that will symbolize the link between the both locations.
- Open up the Geomap from the menu. Click Edit above the map:
- Click on one of the locations that you want to link together and select Link:
- Choose the second location and select Link in the bubble on that location. This will create grey line
between the two locations.
- Click the grey line. Click on Edit in the pop-up bubble.
- Enter a description.
- Select a type.
- Select the object you want the link to represent.
- Click Save to save your link.
