I have a 4.3.28 server running on Ubuntu 18.04 server. The graphs for
the local client look OK except for the "TCP statistics" graph, where I
get IN packets graphed, but the OUT and RETRANS are all NaN.
netstat graph
Graph for a different host (a CentOS 6 server with a -4.3.10 client)
looks fine, all statistics graphed.
I've tried deleting the netstat.rrd for the host, and restarting Xymon
server, but doesn't help. Is there something else I can try? Thanks in
advance.
