So I did a little testing with "route:".
The behavior I see when I test is (where "child" is the machine depended
on the "parent"):
By default (no route directive used here), when the child:conn and the
child:http both go red then the child:http is turned clear because of
innate dependency on conn.
With the route directive in place, when the parent:conn, child:conn and
the child:http all go red then the child:http is turned clear (same as
above) but the child:conn bounces between yellow and red (with an
approximate cycle of 1:30 red and 30s yellow).
Next when I bring up the parent:conn (restore ping function), the
child:conn goes red and stays red.
I guess the bottom line is, I can't get "route" or "depends" to do what I
want or even what the manual says they do. Looks to me like something is
broken real bad.
I am using Xymon 4.3.10.
Anybody have a clue what to do?
cheers,
Troy

Galen,
I should have also stated that google was up for the entire period (no
flapping).
Josh,
I take it, you mean replace my previous configuration where it said:
depends=(http:google.com/http)
and make it:
route:google.com
so it ends up as:
XXX.XXX.XXX.XXX www # trace http://www route:google.com
I tried that and when I block both hosts google/icmp,http and www:http
with iptables they both show red, I was expecting www:http to show clear to
get the same functionality as "depends".
Any thoughts?
cheers,
Troy

#2 sounds a lot like "flapping". Does "depends" honor flapping or
would a flapping server still show red? Or am I not understanding the
situation?

I have the following in my 'hosts.cfg':
209.85.225.105 google.com # http://www.google.com
XXX.XXX.XXX.XXX www # trace http://www depends=(http:
google.com/http)
Yesterday, the web server (www) was down for 55 minutes. The Xymon
record shows that:
1. google.com/http was green for that whole period
2. www/http bounced between red and clear for the whole period (with
a bounce frequency of 5 minutes)
3. My other Xymon server (configured without "depends") shows a solid
55 minute outage (red for 55 minutes).
This behavior is not what I expect from reading the man page.
I tried to reproduce this problem with "depends" on my test Xymon server
and was able to confirm the same behavior.
Is there a workaround to this problem with my Xymon 4.3.10 server?
cheers,
Troy
