In order to understand the overall health of a service, it requires several management tools such as network monitoring (device up/down, switches, etc), device (CPU, Memory, disk) monitoring, application (logs, SNMP, etc) monitoring, etc. The common approach is to use more than one tool such as EMC SMARTS, IBM Netcool, BMC Patrol, home grown monitoring tools, etc. Since there are now multiple tools and multiple consoles with health and availability information, the next common approach is to set up some type of cross product integration like forwarding SNMP events out of SMARTS and Patrol into Netcool. This is a great approach for integrating management tools into a single console, but the problem is, not everything fits (IE: Network Maps in SMARTS, Knowledge Modules from Patrol).
SMARTS does a great job discovering the network, it provides more than up/down events, but most of that information is not sharable to Netcool via an SNMP forwarding mechanism. Patrol has the same challenge, not everything is going to fit inside of Netcool. This is not a negative against Netcool, this is the common challenge with all event managers. Netcool is providing a lot of value around things it is monitoring directly as well as event correlation, de-duplication, etc.
Forwarding events from one management system into another tool provides value, it should not stop there. A single unified console with a Service Catalog type of view into the infrastructure with direct and indirect feeds from the management tools is the approach for end to end management. In the end it places all of the important details at the tips of the Operators fingers and in turn reduces the complexity, knowledge required, multiple tools, etc and in turn you should be able to reduce downtime.
Forwarding events from one system to another is not integrated. Bi-directional interaction (IE: able to receive alarms/events and perform actions such as Ack and Close on them) between the tools as well as an ability to leverage more than just the alarms/events is important. Don’t settle on event forwarding, leverage the investment you made with the other tools.
