Is your business being Proactive in the way that it deals with Service Interruption and Network Faults?
Being "Proactive" means that you become aware of potential problems before they occur, enabling you to actively address them before they turn into full scale service interruptions. Being proactive also means that if service interruption or other outages do occur, that you know about them before your customers and users find out allowing your team to actively work to resolve these issues. In many cases they can be resolved thus going unknown to your clients and the rest of the business.
This is a far more desirable way of running an IT department, rather than being a mostly "reactive" group. Reactive by which means a department that mainly becomes aware of issues only when the users or customers actually phone up to complain being a less desirable way of providing support.
Gaining a "Proactive Reputation" for your department or organisation will pay it's dividends in the long run as the rest of the business begins to realise how efficient the IT team are at minimising service interruptions, and are never caught off guard with unexpected outages.
Becoming Proactive is done by deploying an ample Network Monitoring Solution which will monitor all your network infrastructure including your Servers 24/7.
By deploying such a solution in addition to just monitoring for devices going offline and sending instant notifications to those relevant, you are able to do far more using todays sophisticated solutions. What's more, most of the equipment on your network supports the advanced features of these solutions as they will contain support for SNMP in most cases.
