Re: [Ganglia-general] Sflow Apache metrics
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. On Fri, Apr 10, 2015 at 4:55 PM, Sergey svin...@apple.com wrote: 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!

Re: [Ganglia-general] how to monitor switches?
Hi Aaron - I am not the expert on monitoring cisco switches, but ganglia does support sflow counters, which at least many Cisco switches support -- http://blog.sflow.com/2010/10/ganglia.html http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/system_mgmt/503_U4_1/b_3k_System_Mgmt_Config_503_u4_1/b_3k_System_Mgmt_Config_503_u4_1_chapter_010010.html#task_0AAC420D834048248B9407F9C8559918 Hope this helps!
