The availability monitoring system provides active testing of the IT infrastructure, including:
Availability monitoring is facilitated by:
- Zenping - The system's Layer-3 aware, topology-monitoring service. Zenping performs high-performance, asynchronous testing of ICMP status. The most important element of this service is that Resource Manager has built a complete model of your routing system. If there are gaps in the routing model, the power of Zenping's topology monitoring will not be available. If there are gaps, this issue can be seen in the zenping.log file. Zenping uses Nmap to build a ping tree and perform Layer 3 suppression. The service runs every 30 minutes, which is configurable.
- Zenstatus - Performs active TCP connection testing of remote daemons.
