icmp item problem

[harv3n]

Hello everyone,
first: my english is rusty. p

I got a trouble with an item based on icmp.
my job bring me to zabbix, we have 6 shoppings connected and all of these connecting to a DC.
my problem start here.
one of my items consist in monitoring the latency all of these shoppings of SHOP > Internet and SHOP > DC.
its run ok, but not exactly.
The item return me a result as if send by Zabbix Server.
Example:
Directly from Shop1
Shop1 to internet 23ms
Shop1 to DC 6ms

and from zabbix item
Shop1 to internet 60ms
shop1 to dc 20ms

And my output of zabbix server are directly to internet and secondary to wan, instead of shoppings, where the default output is a router to a wan.

i need a item to that bring me the latency of Host>DC | Host>Internet directly from host.
Its possible with icmppingsec? or just with remote commands?

Thanks a lot!

Hi,
yes you are completely right. The icmp checks are performed by Zabbix server to the host, but not from host. You can perform the SSH connection with specific commands and then you will receive the result back.

Hello and thanks for reply!

the ssh solution,
i saw something about this, running commands with ssh, return that a similar result when i do external scripts or userparameters command?

if i add proxies in each place where i need to monitor, can i ping to a destination from zabbix proxy?

thanks again!

Yes, you can do it with proxy. So if you can put a proxy there - this would be a solution. But after the proxy you need to create the endpoints of those ICMP packets and put them "behind" proxy.

If you have a zabbix agent on each site, you can configure a UserParameter that will ping your DC, and get the result on your server

but the output give to me a string, no?
example when make a ping to 8.8.8.8 and this return "Response of 8.8.8.8: etc etc etc"
has zabbix a way to get ping latency constantly? like icmppingsec but from host to destination

Thanks for reply!

UserParameter=ping.dc,ping -c 4 IP-OF-YOUR-DC | tail -1 | awk '{print $4}' | cut -d '/' -f 2

it should do the trick

wow, nice!!! it worked clean!
thank u dude!

Hi,
yes! This will definitely work (but id on't understand why you want to perform all 4 icmps if you need only one in this case) but also you need to understand that you will receive character-value, not numeric.
If you want numeric - install proxy. Proxy is a very tiny and don't use much of ram or drive space.

Also, i would like to suggest you to use float userparameters, because they are more customizable and this could help in the future. Try something like this:

UserParameter=floatping[*],ping -c 1 $1 | grep -Po 'time=\K[\d.]+'

This will take your value, defined in frontend, (example - floatping[8.8.8.8] or any other [value]) and will put instead of $1. This could be very helpful as well as creating items like icmp $1 will make your item name be like icmp [value]

my shopps are located in different countries and each one with different providers, so, we need to monitor constantily.

i was thinking to make something to convert a numeric return, with python, or other.
ur code work clean too, and easy to understand, i'll try this too.
Thank u!

Use this .sh script, put it in cron and this should do the trick with numeric characters

Read the script, there is a variable for zabbix server and also there is some manipulation with zabbix_get.
