How does the vmstat.rrd file get populated?

So if it's a standard client message shouldn't I see the RRD data if I'm listening in on both status and data channels on the server?You should.I'm using the data from the rrd channels to feed into another product, but I'm not seeing vmstat from the standard client. There's an RRD file and a graph on the trends page showing vmstat CPU utilization but I'm not capturing that data in my file.hobbitd_client will get the client data, hobbitd_client.c's unix_vmstat_report() function pushes the vmstat data to the data channel as $host.vmstat. If I run 'hobbitd_client --channel=data cat' I see: @@data#12492|1309426824.189933|127.0.0.1||tiger.ranger.dnsalias.com|vmstat data tiger,ranger,dnsalias,com.vmstat linux 2 0 208308 139604 75568 694120 0 0 39 93 8291 10748 25 15 59 1 @@
Yes I understand, but that's the plain data I'm looking at the RRD data, but now I'm wondering if I can't have the 2 channels trying to write to the same file. My test yields this as I had to adjust to get the RRD data. The script rf.sh just does exec cat ..//bin/xymond_channel --channel=data xymond_rrd --processor=./rf.sh | egrep -I hostname 148944:3553690822:24878087:12250601:334432899:287987297:43734:236762 hostname netstat bytesSent:bytesReceived 1309440785:0:0 hostname ifstat fjgi0 bytesSent:bytesReceived 1309440785:47813262:6315189681 hostname ifstat fjgi1 bytesSent:bytesReceived 1309440785:241739617836:177888219396 hostname ifstat fjgi2 cpu_r:cpu_b:cpu_w:mem_swap:mem_free:mem_re:mem_mf:mem_pi:mem_po:sr:cpu_int:cpu_syc:cpu_csw:cpu_usr:cpu_sys:cpu_idl 1309440785:0:0:0:7760928:6395480:7:44:0:0:0:241:3773:2452:3:1:96 hostname vmstat So I can verify I'm getting the RRD data, but again I don't think I can write the data from 2 channels into 1 file, At least that's what it's looking like. I don't remember seeing ifstat data in the other application I'm sending this data to. I will post back with my results Thanks all for being a sounding board Greg Shea EMC Corporation
