Try cisco's Response time monitor. The basics should be on most
IOS versions since 11.3.x. The idea is to ping from the router
using SAA, to the server farm default gateway or the server...
or any target that gives a fair impression of user RTT on the link...
As an extra, you can trap on thresholds that you set. Send traps
when the threshold(s) are exceeded....etc...
enable snmp for RTR from config mode:
config#snmp-server enable traps rtr
give the rtr a ref number
config#rtr 18
this puts it into rtr MODE
configrtr18# type echo protocol ipIcmpEcho 199.199.199.1 (the target)
threshold 200 (low time out value)
timeout 1800 (high time out value)
frequency 61 (every 61 seconds, the max)
hours-of-statistics-kept 12 (4 is default, 25 is
the max)
exit (exit rtr mode)
config#rtr schedule 18 life 3000000 start-time now
config#rtr reaction-configuration 18 timeout-enable threshold-type
consecutive 3 action-type trapOnly
cont-Z
This starts rtr now. It will send a trap if echo is over 1800 ms.
It will send a trap if 3 consecutive are over 200 ms. It will send a
different trap
when either come back into spec. Make sure the WhatsUP machine is
snmp-server host,
and that rtr is added to its line
-----snmp-server host 123.123.123.18 communitystring tty config rtr syslog
snmp
and that the trap service on the Wup machine is enabled...
-
To see it from the command line: show rtr dist tab
-
Now in whatsup-config/Monitors+services/
new/snmp Monitoring (NAME RTT200)
object ID 1.3.6.1.4.1.9.9.42.1.2.10.1.1
Range of values
make the low value VERY low
make the high value 200
test fails when exceeded X times
create a device item for the router, services->
monitor RTT200
Argument .18 (the number for this rtr)
Comment something useful
check the box to enable monitoring..
---------
WhatsUp will monitor just about anything that you can find an OID for...
Some of my favorites include- atm OAM cells, T1 and DS3 ESF stats,
router interface errors,

Subject: [WhatsUp Forum] Link monitor
Hi, I'm new to the list... I've been testing WUG 7.4 to check our data
links... I
would like to send an alert (email) to one of my guys if the link RTT goes
beyond 200 ms. We have a VB/Oracle online aplication running thru this link
and every time RTT goes beyond 200 ms the users start to complain about the
performance. Can you help me??? I'm using a Cisco 3600 on one side and a
Cisco 2620 on the other.
Thanx in advance...
