February 18th, 2016 Blog Post Improve Mean Time to Resolution Using NMIS Automated Base Lining By Sharon Hunneybell - General Manager Managing a large complex environment with ever changing operational states is challenging. Several of our engineers who previously managed shifts in large 24hr Network Operation Centres described how they used Automated Live Base Lining when starting a shift and during shift handovers to immediately understand a network’s current health and recent history. NMIS Live Base Lining was able to provide them with a fast synopsis of current network stability and an ability to quickly drill into the most relevant occurrences. Live base lining is achieved by automatically calculating a single “network wide” health metric, reachability metric and availability metric as seen in this graph. The secret to showing engineers where to look for deteriorating conditions is that the current state (metrics) of your network are then continuously compared against a rolling period (configurable, last 8 hours by default) to see whether performance is deteriorating or improving. This is done not only on the network as whole but also on subsections (groups) of your network. Status trends are reported visually using arrows to show if health is improving or declining. You can then drill-down into more detailed KPI data for an individual device. The visual alerts, along with the ability to very quickly access detailed information relating to performance deterioration allow an organization to identify issues and make corrective decisions faster – vastly improving mean time to resolution (MTTR).
