Ping host from zabbix-agent

[sabat]

Hello,

as i have my zabbix 4.4 on VPS machine, remote location, i'm trying to run ping (latency response) from zabbix-agent machine in my network.


5 years ago someone posted this, but I cant get it to runn - I have no data....

UserParameter=chk.fping[*],sudo /usr/bin/fping -c 3 $1 2>&1 | tail -n 1 | awk '{print $NF}' | cut -d '/' -f2 Add permition in /etc/sudoers because of error in creating SOCKET.
zabbix ALL=(ALL) NOPASSWD:/usr/bin/fping
In template you can add items you'd like to ping
chk.fping[8.8.8.8]

When i run as root

/usr/bin/fping -c 3 $1 2>&1 | tail -n 1 | awk '{print $NF}' | cut -d '/' -f2

from command line it is working...

any help?

On the machine running the zabbix-agent, first create a directory that zabbix can safely write to while debugging:

mkdir /tmp/zabbix-debug
chmod 700 /tmp/zabbix-debug
sudo chown zabbix /tmp/zabbix-debug

Then modify the UserParameter to do this:

[B]UserParameter=chk.fping[*],sudo /usr/bin/fping -c 3 $1 2>&1 | tee -a /tmp/zabbix-debug/chk.fping | tail -n 1 | awk '{print $NF}' | cut -d '/' -f2[/B]

then restart zabbix-agent on that system so it reads the updated UserParameter.

Look at what gets written to /tmp/zabbix-debug/chk.fping to see if that gives you a clue about what the problem is.

Once you've got it figured out and fixed, be sure to remove the "tee -a /tmp/zabbix-debug/chk.fping" from the UserParameter, and restart, so it don't keep appending output to that debug file.
