DCI Parameters
Notes on using particular DCIs
ChildStatus
ChildStatus can be used to check status of child items of the nodes, particularly:
- Network Service
- Interface
While using ChildStatus to check status of the interface, keep in mind, that depending on the device/vendor object ID of the interface might change between the configuration polls. For Cisco switches there's way to preserve ifIndex for the interfaces using snmp-server ifindex persist command (read more about that on Interface Index (ifIndex) Persistence)
PS: This might require entering command in interface (rather than global) context. PPS: Not sure if works everywhere... write mib-data might be needed as well
Node interface
Notes on working with node interfaces
Parameters
Required poll count
NetXMS will consider interface down only after given number of unsuccessful polls.
Event Processing Policy
SYS_* Events
Please note, that as part of internal event correlation, no SYS_* events processed from the node after receiving SYS_NODE_DOWN event, until SYS_NODE_NORMAL received from that node. However, custom events processed just fine even after SYS_NODE_DOWN event.
Macros for Event Processing
Note, that different set of macros available for Activation and De-activation of alarms. For example, if you use unique DCI ID for alarm generation (%5), you should use different macro to de-activate this alarm (%3)
