High Availability
High Availability Considerations¶
The SNMP protocol uses UDP as the transport protocol and is subject to network reliability, as a constraint. Network architecture should be considered when designing for high availability.
- When using a single node collector ensure automatic recovery from virtual infrastructure i.e. VMware, Openstack, etc.
- When using a multi-node cluster ensure nodes are not located such that a simple majority of nodes can be lost for example consider row, rack, network, power, storage
- When determining the placement of clusters the closest location by the number of network hops should be utilized.
- For “data center” applications collection should be local to the data center.
- Consider IP Anycast
