Is there a simple trigger that actually work for IP availability?

[xcalibur]

Hi,

I simply would like to know wether or not my servers are online.
Ping Check\unreachable for 3 minutes and what not keep spamming my mail with false results.

Is there a simple syntax that work properly?

Thanks

I'm having exactly the same problem...

Anyone?

yes you can use simplechecks.. icmpping

Thanks, I'll try that...

We had problems when sometimes a machine wouldn't reply back to a ping ocassionally, but was actually online. So now for a trigger we use this:

{Template1:icmpping[].last(0)}#1 | {Template1:icmpping[].nodata(120)}=1

Admittedly last(0)#1 is probably a bit pointless as if the host is offline then it's not going to reply with anything. So if we get no reply for 120 seconds (the ping item is every 60 seconds)

For remote servers where pings are even more unreliable we use the trigger with a ping item every 30 seconds:

{Template2:icmpping[].avg(210)}<0.5 | {Template2:icmpping[].nodata(210)}=1

Now I'm using icmpping with this expression,
{Template_Windows:icmpping.count(300,0,"eq")}>3
and it's working fine.

Now I'm using icmpping with this expression,
{Template_Windows:icmpping.count(300,0,"eq")}>3
and it's working fine.

I'm trying to understand your trigger, can you tell how to "read" it. Thanks!

This is my understanding...

I set one simple check item, icmpping, to ping every minute (fping is required).

This expression counts the number of failed pings (status equals to "0") in the period of 5 minutes (300 seconds).
If it is grater than 3 (out of 5) then there is a problem.

Hope this helps.

Hello everyone,
Would like to share with you guys my solution for this particular issue. Because of the different circumstances I`m doing following (might be useful for someone, cause using this method we don’t need zabbix agent at all)

ITEM
Description: Exchange servers connectivity
Type: Zabbix trapper
Key: eserv.connect
Type of information: character

TRIGGER
Name: No connectivity to Exchange server
Expression: {EXSERV:eserv.connect.strlen(0)}#1


I have perl script, which is located at the same server where zabbix server is.

#!/usr/bin/perl
#following scripts monitors Exchange servers connectivity status;

	if( system(" ping -c 2 192.168.25.142 > /dev/null ") )
	{
		system(' /usr/local/bin/zabbix_sender -z localhost -s " EXSERV " -k eserv.connect -o "Cannot PING Exchange server" > /dev/null ');
	}
	else
	{
		system(' /usr/local/bin/zabbix_sender -z localhost -s " EXSERV " -k eserv.connect -o "0" > /dev/null ');
	}
exit;

This is it!! Link to this script I placed in cron and cron is running it once every 15 minutes

Thanks for sharing...

Just incase you weren't aware, icmpping[] doesn't require a zabbix agent. So the script method above seems rather long winded.
