need help with ping latency in simple check.

[easy_john]

I would like "to add" simply, for the hosts necessary to me, a template in which there would be a check of its availability without the agent established on host.
I.e. the same as " simple check ".

Now I am compelled to check the necessary network devices by means of a script from fping, started by the agent, on one of host, transferring it the address of a host.
It causes inconvenience.

Whether it is possible to bypass this problem somehow?
I would like to have statistics on delays up to the necessary host, simply attaching a template to a host.


PS sorry, machine translation.
PPS hate situation, when i need talk to another russian speaking people (zabbix autor) in foreign language. is there are somewhere russian support community?

1) Create new Template
2) Create new Item, type "Simple check"
2.1) description: http
2.2) key: tcp,80 (tcp,22 -- if you want SSH; icmpping -- if you want ICMP ping, but you'll need fping set up correctly)
3) Link needed hosts with this new Template

Create triggers and actions as needed.

That's it.

i have fping binaries, but with this type of simple check i do not have data with latency or %packet loss. what is wrong?

Enable debug logging in zabbix_server.conf,
check that Pingers do actually start
(Pingers variable in zabbix_server.conf)

`tail -F zabbix_server.log` and try to guess
what's wrong.

To simplify debugging you could use this patch
(it gives you the name of each zabbix_server process
in `ps -ef` output):

I had hard times configuring fping with Zabbix also

[fableman]

the ping function in zabbix you should not use if you looking for real ping times.

problem with fping and zabbix is that zabbix only send 1 ping to meassure the time. That will result in strange values on some network items.

some network switches,routers dont priority ICMP (ping) soo one ping from zabbix can give you times around 1000ms when its around 1ms normally.

Soo use my ping script instead The script will send 5 pings at the speed of 25ms and report back the ave ms soo all peak numbers gets even out.

Put my script at: /etc/zabbix/externalscripts/


#!/bin/sh
tal=`ping -c5 -i0.25 $1 | tail -n 1 | awk '{print $4}'| cut -d/ -f2`
if [ -z $tal ]
then
echo 0
else
echo $tal
fi


then make triggers to alert if ping times is 0ms or over 300ms for example.

Good luck.

similar problem with external check for packetloss

I added
Host:
grouped

IP-adress

connect to IP-adress
port80
status monitored

Item:
ext. check
key: packetloss23.sh[]
numeric (64bit)
units:ms
no multiplier
update intervall 60
status: active
store value as is
show value as is

packetloss23.sh:
#!/bin/bash
IP=`mysql -b -D zabbix -u zabbix -pxxxx -e "SELECT ip FROM hosts WHERE host='$1' LIMIT 1" | cut -f2 | $
/bin/ping -q -n -c 23 -w 2 $1 | /bin/grep "packet loss" | /usr/bin/cut -d " " -f 6 | /usr/bin/cut -d "%" -$

first it doesnt seem to find to script, then it cant return anything, I dont get it
