Included Analyzers

IPAM Pool Utilization

A warning will be generated when at least 85% of the available IPs in the Weave subnet are in use by pods.

IPAM Pending Allocation

A warning will be generated when there are pods waiting to be allocated an IP. This indicates that there are currently no available IPs in the pool.

Connection Not Established

A warning will be generated when a connection between nodes is not in the established state. A connection in the pending state may indicate that UDP is blocked between nodes and a connection in the failed state may indicate that the Weave pod on the peer node is not ready.

Connection Protocol Sleeve

A warning will be generated when the connection between nodes is using the sleeve protocol rather than the fastdp protocol.
