Hello All,
Can someone give me some pointers on
developing my own rrd scripts and graphing.
I’ve read Hobbit Help pages, looks fairly
straight forward. I can write the script, but
what output should the data be in?
I’m going to write a couple scripts, can
someone give me how the data should look,
and perhaps how the hobbitgraph.cfg should look?
A) I’m going to write a script to track iostat disk
busy and wait states for both nfs and disks, and
graph them.
iostat –xn
extended device statistics
r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device
4.3 2.9 138.3 33.6 0.0 0.1 1.1 19.8 0 2 c1t0d0
4.0 2.9 139.8 33.4 0.0 0.1 1.1 21.1 0 2 c1t1d0
0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.8 0 0 c0t0d0
0.0 0.0 0.0 0.0 0.0 0.0 0.0 20.3 0 0

server2:/home/ms
0.0 0.2 0.4 0.6 0.0 0.0 0.0 3.0 0 0
server1:/home/james
So, for each system, I’d like to graph %w &%b, and I may setup alerts
for %w…
How should I sent the data to rrd, the script output format?
B) I’d also like to use the mpstat command. I want to plot the usr,sy,wt,idl
of all processors and graph all processors on a single graph.
CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr sys wt idl
0 132 2 195 57 41 509 17 64 16 0 1260 2 2 1 95
1 172 2 310 378 266 516 16 64 18 0 1619 2 2 1 96
I can write the Hobbit/BB scripts, if someone can recommend the output
format and the hobbitgraph.cfg suggestion, it would be helpful.
If anyone wants a copy of the script(s) afterward, I’m more than happy to
provide.
Thanks….James
