Hi,
I just upgraded from 4.4 to 4.8 (going from Debian jessie to stretch) and hit a
problem with xentop. On 4.8 xentop shows only zeroes for network traffic.
I did some debugging and the problem appears to be that in
xenstat_collect_networks (in libxenstat_linux.c) the following conditional is
true
if ((strstr(iface, devBridge) != NULL) &&
(strstr(iface, devNoBridge) == NULL) &&
((domain = xenstat_node_domain(node, 0)) != NULL)) {
I use vif-route, so I have no bridge: devBridge points to an array of \0s. So
strstr says this empty string is a substring of vifn.0. Then it seems to act as
if I am actually using a bridge and fails.
As a workaround I replaced the conditional with
if ((devBridge[0] != 0) &&
(strstr(iface, devBridge) != NULL) &&
(strstr(iface, devNoBridge) == NULL) &&
((domain = xenstat_node_domain(node, 0)) != NULL)) {
This solved the problem for me, although I’m not sure at all if this solution
is correct in general.
Best,
Bas
