Have you installed sflowtool and seen if the sflow counters are even
getting sent out by the machine ? My next step would be a tcpdump to
make sure that the sflow counters are then getting sent to the
collecting host.

Hi All!
I installed mod_sflow on Apache and try to collect HTTP metrics by Gmond.
The problem is that I don’t see any HTTP metrics coming from Hsflow to
Gmond, nor HTTP counters via Apache http://hostname/sflow page.
There is a list of counters, but they all have 0.
Like this:
unter method_option_count 0
counter method_get_count 0
counter method_head_count 0
counter method_post_count 0
counter method_put_count 0
counter method_delete_count 0
counter method_trace_count 0
counter method_connect_count 0
counter method_other_count 0
counter status_1XX_count 0
counter status_2XX_count 0
counter status_3XX_count 0
counter status_4XX_count 0
counter status_5XX_count 0
counter status_other_count 0
string hostname xx
gauge sampling_n 0
At the same time http://hostname/server-status?auto is working properly:
Total Accesses: 15
Total kBytes: 5
Uptime: 149
ReqPerSec: .100671
BytesPerSec: 34.3624
BytesPerReq: 341.333
BusyWorkers: 1
IdleWorkers: 7
Scoreboard:
Is there a way to troubleshoot this? I need Sflow metrics.
Thanks!
S.
