System information

Q. Why Don't ping and traceroute work?
NMIS was written on Solaris so until version 2.2 is finalised there are some hard-coded file locations you
might have to change in /bin/admin.pl change the file locations for ping, traceroute etc. to suit your machine
(the command 'which ping' will tell you where it lives)
You may need to change the syntax of ping - for eample the following works in Linux at about line 89 of
/cgi-bin/admin.pl
if ($admin eq "ping") {
$adminoutput=`/bin/ping -c 5 -s 64 $node`;
}
The same applies for other commands. This will be automagically fixed in 2.2 :)
Q. Why Aren't I getting any stored reports?
Change the first line of run-reports.sh to #!/bin/sh if you don't have ksh at /bin/ksh ('which ksh' will tell you
where it is or report an error if you don't have it at all.) Check that the path listed in the script will find all the
commands listed in the file eg. date, col etc. Again, you can find their locations with 'which commandname
Q. How is the Group Summary metric derived ?
Reachability is 40%, health is 40% and availability is 20%.
Q. What are the weighting for the Health Metric ?
A. This more fully explained in the NMIS Changelog but the basic info is:
reachability is 30%
interface utilisation is 20%
response time is 20%
availability is 10%
CPU is 10%
MEM is 10%
Interface Utilisation consists of all interface input and output utilisation are each subtracted from 100, added
together and then averaged, this number is the interface weight, this will contribute 20% of the health metric
and should be quite responsive to interface utilisation.
Q. Can NMIS handle SNMP traps and syslog?
A. No. But the NMIS event subsystem could be used in a real time event system. It would be possible to
integrate NMIS into the Perl Syslog Daemon @ http://www.weirdness.net/acd/code/syslogacd or into
NET-SNMP which includes a trap daemon, some details are available @
http://www.sins.com.au/nmis/net-snmp.html.
