Very Computer

Hi:

I would like to get input on performance monitoring tools, we are running
a Sun clone 4.1.1, under a T1 link, from xload, it is about 0.1, however,
we do expect some network traffic, telnet takes about 30 seconds to
prompt from remote login, no job can be done via this T1 line, just too
slow.

could someone suggest some PD tools that one can monitor the load on
cpu, as well as network traffic, right now, we are not sure what the
problem is.

Thanks in advanced!

You might try rperf:

rperf -- performance monitoring of network hosts

"rperf" is free software, written by me, and posted to
comp.sources.misc, vol 39.  Archie has the locations now.  Otherwise,
mail me for the code.

Quote:>From the README:

rperf is similar to xmeter, or SunView perfmeter, but is intended for
use on ascii terminals or for logging.  rperf obtains system statistics
from one or more network hosts and prints them to the standard output
at periodic intervals, in a format similar to rup, vmstat, and
netstat.  rperf reports on cpu load, disk activity, network interface
activity, and virtual memory activity.

If installed as rup, the program prints the hostname, uptime, and load
average once, then exits.  A hard or symbolic link to rperf may be used
for the installation.
