... [capture trimmed: first 60 of 980 lines]

Two questions this answers well: whether the process you expect is listening on the port you expect, and whether the node has an established connection to the control plane. A CE with no established outbound connections to F5 infrastructure is a node that will not register, whatever else looks healthy.

The output is long — the capture above is trimmed — so pass arguments to narrow it rather than reading it whole. Note that the hostname column is truncated to fit, which matters if you are grepping for a full node name and finding nothing.
