Dear alexei,

Im still experiencing the same problem, i have tested this same situation over and over again.

Is this a bug in the new version? Because before it worked fine except when they came back online, now its other way around.


Edit:

i found the problem, i use simplecheck ping for the webservers, router, and switch. This to be independent from the zabbix agent, simplechecks are all checked at the same time.

Is there anyway to get around this?

[michaeltje]

You may want to check availability of the router more frequently than availability of servers behind the router.

How should i fix this alexei?

It looks like I have the same problem here... Could anyone explain how one needs to set up the dependencies with routers, switches and servers. Dependencies on services works fine.

Please let me know what information is needed.

Any help is highly appreciated :-)

Kind Regards,

Remi

You should be checking routers at least twice as often as servers.

say your server availability trigger is every 10 minutes (600 seconds)
Then your router check should be less. I would do about 250 seconds to make sure its fully completed in time.

There should be two ways to do dependencies. One using the trigger expression and the other using the dependency selection gui.

dependency as a trigger expression:
e.g. (This is not a great example, but should get the idea across. My availability stuff is much more complicated, which i tried to simplify)
({hostname:system.cpu.util[].nodata(600)}=1)&({routeringer.nodata(250)}=1)

or Using the dependency selection when configuring the trigger.

I tried the dependency selection method originally, and I think there were bugs in it about 10 versions back and haven't tried it since.

I think the difference with the two dependencies is that

GUI-
-Easier to configure
-Trigger activates if the host is down but does not run an action unless the dependences are up.

Expression-
-Possibly more difficult to configure
-Trigger can activate only if exression is true which means the host has to be down and the router (dependency) has to be up.

I modified my availability triggers...

Looks pretty need. You can assign dependencies to a trigger that is assigned to a host which in turn is linked to a template. Coool!

Haven't tested if it works properly though

Hey infinity,

Thanks for your help, its apreciated.
We have tested the method you stated above, tho its not really working as i expected.
We are gonna try to test it with the trigger expresions. Will keep you updated.

It is fixed in pre 1.4.2 code. Please feel free to download it from www.zabbix.com/developers.php.

Dear alexei,

We have tested the same situation, I have the following triggers:


#Gateway
{Gateway:icmpping.max(180)}<1

#Switch
{Switch:icmpping.max(240)}<1

#Server
{Server:icmpping.max(300)}<1

This works perfect, if the connection between the gateway and the zabbix server goes down i get one email. But if i restore the link, i get the mail from the gateway and the server (Kinda weird, it never messaged me about the server going down).

So is this a bug in the software or am i doing wrong things?

I will retest this functionality and report back soon.

I will retest this functionality and report back soon.

That would be great, i tested it on a new hardware box now aswell, the dependency's work great when the stuff goes down, when it gets up it messages me about everything.

Thanks for ur help its really appreciated!

[Alexei]

Please confirm that you are using ZABBIX 1.4.2.

[michaeltje]

Please confirm that you are using ZABBIX 1.4.2.

yes i am using 1.4.2

[michaeltje]

Anything new yet alexei?

Thanks in advance!

[bbrendon]

I'm adding dependencies to items that are associated to templates. I'll let you know if it works. I don't think it does.

[Alexei]

Trigger dependencies are fixed in the latest pre 1.4.2 code. I am sure it works fine now. The Manual was also be updated to descibe new functionality.
