Good Morning.
I am using debian buster 10.4 with iproute2 compile version 5.7.0.
I am testing Traffic Control but on the statistics no Rate value is shown.
For example in the following link "https://paste.ubuntu.com/10963208/";,
i see following output:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
jjo@jjo-x220:~/tmp$ ./iproute2-3.19.0-jjo/tc/tc -s class show dev eth0
class htb 1:10 parent 1:1 prio 0 rate 2500Mbit ceil 2500Mbit burst
15000b cburst 1250b Sent 699143 bytes 5790 pkt (dropped 0, overlimits 0
requeues 0) EST32 rate 0bit 0pps backlog 0b 0p requeues 0 lended: 5733
borrowed: 0 giants: 0 tokens: 761 ctokens: 74
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I am seing "rate 0bit".
But installing from debian package iproute2 i got nothing so i decide to
compile iproute2 using version 5.7.0
But my output is the same as below:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
# tc -s class show dev enp4s0 | grep 1:30 -A 4
class htb 1:30 parent 1:1 leaf 30: prio 1 rate 3Mbit ceil 3Mbit burst
5Kb cburst 1599b

backlog 0b 0p requeues 0

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I did following changes in tc/tc_util.c for printing the rate enclosure
after and before condicion of printing rate:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
843a844
> printf("->");
865a867
> printf("<-");
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The section of tc_util.c show like this :
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
printf("->");
if (tbs[TCA_STATS_RATE_EST64]) {
struct gnet_stats_rate_est64 re = {0};
memcpy(&re, RTA_DATA(tbs[TCA_STATS_RATE_EST64]),
MIN(RTA_PAYLOAD(tbs[TCA_STATS_RATE_EST64]),
sizeof(re)));
print_string(PRINT_FP, NULL, "\n%s", prefix);
print_lluint(PRINT_JSON, "rate", NULL, re.bps);
print_string(PRINT_FP, NULL, "rate %s",
sprint_rate(re.bps, b1));
print_lluint(PRINT_ANY, "pps", " %llupps", re.pps);
} else if (tbs[TCA_STATS_RATE_EST]) {
struct gnet_stats_rate_est re = {0};
memcpy(&re, RTA_DATA(tbs[TCA_STATS_RATE_EST]),
MIN(RTA_PAYLOAD(tbs[TCA_STATS_RATE_EST]),
sizeof(re)));
print_string(PRINT_FP, NULL, "\n%s", prefix);
print_uint(PRINT_JSON, "rate", NULL, re.bps);
print_string(PRINT_FP, NULL, "rate %s",
sprint_rate(re.bps, b1));
print_uint(PRINT_ANY, "pps", " %upps", re.pps);
}
printf("<-");
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
And as you can see no rate is being printed, does int need to be enable
something else to print the rate?, now with the changes done i Got:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
# tc -s class show dev enp4s0 | grep 1:30 -A 4
class htb 1:30 parent 1:1 leaf 30: prio 1 rate 3Mbit ceil 3Mbit burst
5Kb cburst 1599b
Sent 35713116 bytes 72643 pkt (dropped 26, overlimits 16464 requeues
0) -><-
backlog 0b 0p requeues 0
lended: 71083 borrowed: 0 giants: 0
tokens: 209078 ctokens: 62406
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
As you can see "-><-" is being printed.
Is necessary to do something else to get tbs[TCA_STATS_RATE_EST] working?
Even i compile the last kernel 5.7.2.
Any guide option or value that must need the processor, network card,
hardware, etc for this?
