This is somewhat off-topic as not directly related to RRD,
but is 1
of the most popular req. hence would like to share what I
realised about this issue until now in my effort to solve
There are 2 sides to unix perf monitoring -
1] real-time monitoring
needs to be collected locally OR remotely
must be uploaded locally OR at a central
machine to RRD/whatever for immediate
through gnuplot/RRD generated images etc.
2] trending for a later review of sys perf.
can be achieved by locally collecting data
available through batch upload in
RRD or excel or
other sorts of summerising tools.
One soln that caters both will be great but seems not
possible to me in my case.
impl Difficulties -
certain data has variable format (field
positions/no) [e.g. disk r/w data due to
variable no of discs]
maintaining custom RRD formats for diff servers when
these also keep changing
from time to time is painfull (maintainance
In comparison for eg 'vmstat 300 2|tail -1' is
relatively easy and standard across
systems hence easier, so also ' sar -u'.
existing Solutions -
'big brother'/larrd has some stuff to plot the sysperf data
but can't be used if u just want
the trending feature.
Cricate contributed sw has a link -
but hasn't been able to test it out.
Current status for my work -
Have been gathering/graphing vmstat data on a central
server. But variable format
data like mpstat/iostat is making me rethink about the
direction of the effort.
