[Xymon] is depends broken?

[Troy Adams]

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

Use route: other.host.com

#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
