Custom Dashboard Best Practices
Set your canvas properties accordingly:
Develop your dashboards using whatever resolution is appropriate for whatever resolution/size screen you need to view it on in the NOC/SOC/desktop/laptop and adjust your layout accordingly. Tip: If you create a background image of the desired size you can use it as a guide for your Dashboard layout.
Rely on a graphics designer or learn to use Adobe Photoshop or a free tool like GIMP to create images with transparent sections.
Maintain a high-quality (vector images if possible), image library in a desktop folder and import one or more images from there.
Limit your Dashboard images to less than a total of 5 MB/200 images if possible.
Please keep in mind that if you use too many images /nest too many urls/dashboards, dashboard performance may be adversely affected.
The size of the data returned for a dashboard should not exceed ~5 MB. If it does, you may observe slow response. In order to estimate the data sent for a panel you can use the following guidelines:
Gauge, meter, slider: on average 50 bytes
Chart: on average 50 bytes for each sample
Table: size of data returned from query + overhead for each cell equal to (the length of the column name times 2) + 5 bytes.
Try also to keep your Dashboard levels/links to a total of 3 LEVELS deep.
Dashboard size/scope: create dashboards with future needs in mind so you plan for enough space to add more objects/images if needed, e.g., more servers, more images, more customers, devices, etc. Keep the dashboard flexible/adaptable.
