Network device monitoring and fault management
OpManager monitors network devices — routers, switches, firewalls, load balancers, UPS systems, printers, and other SNMP-capable hardware — through continuous SNMP polling. The platform ships with over 600 vendor-specific monitoring templates covering Cisco IOS and NX-OS, Juniper Junos, Fortinet FortiOS, Palo Alto PAN-OS, HP/Aruba, Huawei, MikroTik, Ubiquiti, and hundreds of other device types. - Each template activates the relevant OIDs for the device type — interface status and throughput, CPU and memory utilization, hardware health sensors (temperature, fan, power supply), and device-specific metrics — without manual OID entry. - Fault management handles device-down events and threshold breaches through a rules engine that correlates related alarms, suppresses dependent alerts when a root-cause device fails (preventing alert storms from downstream devices going unreachable), and routes tickets to ITSM systems.
