The ease at which you can set up rules for different types or data sources, such as web servers/applications etc., makes it very easy using this product! Nothing really comes across in my mind that I dislike - but there are no complaints either (and we're an organization with many customers!). As mentioned above; however difficult they make setting things like alerts out may be too much work sometimes? If your team has enough people then maybe not necessary if its only one person who will use them regularly though :) Definitely try these products before buying so you don't have regrets afterwards!! For example:- Setting alarms from multiple points- Different levels depending upon severity.- Being able pull information off other systems without having 2 separate applications running simultaneously when needed.
