I'm using radeware to monitor multiple servers (3-4) that are located at different places across our organization so it's easy from one location or any remote device/computer we use when out there! Nothing yet :) But they do have some great support options as well where you can get your questions answered quickly without having an actual engineer come over just ask! The price point is very affordable compared with other products around but if this does not fit what yuor business needs then maybe go ahead withe more expensive alternatives like New Relic etc.. We're solving problems related tot he performance monitoring part within my department which previously was unmonitored due latency issues between users accessing server data remotely through web browsers such us chrome vs firefox /IE - all slow downs were because these browser had been updated lately causing extra load onto system resources while rendering pages!
