What I don't understand is your "conclusion" (from the subject) :
"unable to ping".
If there is 40 or 60% failure rate then it's still able to ping, it's just
that not all packets are coming back within the calculated time.
A "normal" ping from the commandline isn't a good meter to see if you get
the same or not. You should also interprete the the numbers that the
commandline ping is giving in order to understand.
The best would be (but almost impossible unless you have the problem all the
time) a trace (netmon/ethereal/sniffer/...) showing the ping that SA does,
this will also show the reponse (if any) and then you will see how long it
took and understand WHY you get the down and see if it's correct or not.

I've been using SA for a year or two now.
I understand the way it works.

This shows that SA is able to ping.
Maybe you're not understanding the way it works... (and the doc isn't 100%
clear on it either).
Example:
timeout 5 seconds
10 frames
75% successrate
SA will send 10 frames and each of them should get a response within
5s/10=.5s
If we get the response we will internaly flag the frames as being
OK.
(the next frame is send AFTER the timeout of the previous OR when
the previous gets back).
After the 10 frames we will "calculate" the % of frames that came
back within time and see if that fits the given rule (75%) and based on this
give an OK or DOWN.
Dirk.

The log says that it is a success rate problem. On the last 2 checks one
failed at 60% and the other at 40%. I don't have a problem with timeouts
from the command line.
The system has one NIC. I've tried both hostname and IP. SA is running as
an application.
Thanks,
Lem

What exact message in the logfile?
Does the system have more then one NIC?
Are you ping a hostname or an ip address?
Are you running SA as service or as application?
Dirk.

Subject: [SA-list] Unable to ping
Hello all,
I am running SA 4.0.1376 Enterprise on a Win XP Pro machine.
I have checks setup to check inside and outside of my local network.
Everything works as expected except for external ping tests.
I can ping the external machine from a windows command line, but SA will not
complete the check.
If I could not ping from the command line I would suspect my firewall, but
since I can I really don't know where to start.
I checked the archives and saw a similar problem in January this year, but
it did not have a resolution posted.
If anyone has an hints they would be greatly appreciated.
Thanks,
Lem
