Set item type of information to Text then you will see the output (maybe some useful error message).

When I set items to text, nothing happened becouse It looks like Zabbix didn't run the script.

But, rememberer that, in this solution, zabbix_sender is used, so you have to have (in zabbix server configuration) zabbix traper active (more than 1).

I have found only this: StartTrappers=5
Do you wrote about this option?

Every time you use the script:
./zbxsmokeping 127.0.0.1 6 1000 68 localhost
4 new values are send to server so should be visible on SmokeItems.

Yes 4 values are sending and I see them. But it only works when I manualy start it from shell. Zabbix dont start script...

OK,
Michał

check if on Debian distro Zabbix looks for external scripts to /usr/local/share/zabbix/externalscripts ....
What is in log? /var/log/zabbix/zabbix_server.log (or any other location).

Look in zabbix config where the logs are, and where external scripts should be.

By default there wasnt 'externalscript' folder so I create one.
In config was only comment

Code:

# ExternalScripts=${datadir}/zabbix/externalscripts

So I add line:

Code:

ExternalScripts=/etc/zabbix/externalscripts/

I uploaded zbxsmokeping to /etc/zabbix/externalscripts/ and changed its code to:

Code:

# where is fping tool?
FPING=/usr/bin/fping
# where is zabbix_sender tool?
ZBXSENDER=/usr/bin/zabbix_sender

I also chmod to 755

There are no errors when I run ./zbxsmokeping and it works, It send values and I see them in Zabbix latests data.

But Zabbix 'auto job' dont run script automaticly every x minutes...

Simple Q: did you restart zabbix server

Yes, I did

many times

**mbsit** · 11-07-2013, 15:04

What "Latest data" shows?
In the column 'Last check' the time is changing at item 'Smoke Inicjator'?

Try to set debug mode (zabbix config file), restart the server and look into to the logs.

Yes, column 'Last check' time change every 10min. I did a little debugging and Zabbix run automaticly script but have some problem with it.

I change your script to something like this:

Code:

echo "$IP $COUNT $INTERVAL $BYTES $HOSTNAME" >> /etc/zabbix/externalscripts/log.txt
...
...
# debug
echo $ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLoos -o ${tab[0]} >> /etc/zabbix/externalscripts/log.txt
echo $ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyMin -o ${tab[1]} >> /etc/zabbix/externalscripts/log.txt
echo $ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyMax -o ${tab[3]} >> /etc/zabbix/externalscripts/log.txt
echo $ZBXSENDER -z $ZBXSERVER -p 10051 -s $HOSTNAME -k SmokLatencyAvg -o ${tab[2]} >> /etc/zabbix/externalscripts/log.txt

And changed chmod of folder to 777.

I create script in administrator->scripts

Code:

/etc/zabbix/externalscripts/zbxsmokeping {HOST.IP} 6 1000 68 {HOST.HOST}

And when I clicked on host and choosed from popup menu this script everythink works ok and in log.txt I see:

Code:

10.100.80.1 6 1000 68 10.100.80.1
/usr/bin/zabbix_sender -z 127.0.0.1 -p 10051 -s 10.100.80.1 -k SmokLoos -o 0
/usr/bin/zabbix_sender -z 127.0.0.1 -p 10051 -s 10.100.80.1 -k SmokLatencyMin -o 0.35
/usr/bin/zabbix_sender -z 127.0.0.1 -p 10051 -s 10.100.80.1 -k SmokLatencyMax -o 0.61
/usr/bin/zabbix_sender -z 127.0.0.1 -p 10051 -s 10.100.80.1 -k SmokLatencyAvg -o 0.49

But when Zabbix starts script automatically, there is only this in log.txt:

Code:

10.100.80.1 6 1000 68 10.100.80.1

So it crashes on this line I think:

Code:

OUTPUT=`$FPING -b $BYTES -c $COUNT -q -p $INTERVAL $IP 2>&1 | awk '{print $5,$8}' | tr -d "%|," | tr -s " " "/" | awk -F"/" '{print $3,$4,$5,$6}'`
tab=( $OUTPUT )

**pad19** · 11-07-2013, 15:35

Yes there is crash

Code:

 echo $FPING -b $BYTES -c $COUNT -q -p $INTERVAL $IP 2>&1 >> /etc/zabbix/externalscripts/log.txt
echo "tutaj1" >> /etc/zabbix/externalscripts/log.txt

OUTPUT=`$FPING -b $BYTES -c $COUNT -q -p $INTERVAL $IP 2>&1 | awk '{print $5,$8}' | tr -d "%|," | tr -s " " "/" | awk -F"/" '{print $3,$4,$5,$6}'`
echo "tutaj2" >> /etc/zabbix/externalscripts/log.txt

This is log when I run it:

Code:

10.100.80.1 6 1000 68 10.100.80.1
/usr/bin/fping -b 68 -c 6 -q -p 1000 10.100.80.1
tutaj1
tutaj2

and this is log when Zabbix runs it:

Code:

10.100.80.1 6 1000 68 10.100.80.1
/usr/bin/fping -b 68 -c 6 -q -p 1000 10.100.80.1
tutaj1

Of course, user 'zabbix' has no rights to command fping.

ALWAYS !! Check scripts on user zabbix not root!

# su - zabbix

and then try to run my scripts.
Or you don't have 'fping' utility because this is not standard tool.

YES YES I KNOW!

I did it from beginning. I run as zabbix and zabbix have rights to fping. And also zabbix user run script with no errors. Also zabbix user via script.php runs your script well. But when zabbix tries automatically runs it every 10min it gives crash as I showed in previous post...

So I think it can't handle something from this "| awk '{print $5,$8}' | tr -d "%|," | tr -s " " "/" | awk -F"/" '{print $3,$4,$5,$6}"

**mbsit** · 11-07-2013, 17:09

Wrrr..

still thinking ...

Did you find any messages in zabbix_server log file in zabbix debug mode?

Yes I know that it is very strange... It runs via script.php as zabbix user, but automatically as also zabbix user it cant... WTF?!?

even more strange that the input parameters to your script in both cases are the same and are ok...

In debug=4 I found something like this:

I see there is extra quotes added "" maby this is wrong

no, I just run with extra "" from console and it is ok...

What about double // ? Remove last '/' in zabbix config file... where you set external scrript path ...

No ... it cant be .. the script is run correctly ...

Try to cut my OUTPUT to sections one, by one ...
like:
OUTPUT=`$FPING -b $BYTES -c $COUNT -q -p $INTERVAL $IP 2>&1`

Set the item Inicjator to text mode, and look what will be the output.

**pad19** · 11-07-2013, 20:37

SOLVED

After all day I solved it... ;p

Script 'zbxsmokeping' in default configuration needs about 6 sec to execute.
In Debian default Zabbix configuration from repository looks like this:

Code:

### Option: Timeout
#	Specifies how long we wait for agent, SNMP device or external check (in seconds).
#
# Mandatory: no
# Range: 1-30
# Default:
# Timeout=3

So I just add line:

Code:

Timeout=7

Restart zabbix-server and everything works perfectly

I want to thank Grzegorz - mbsit for writing the script and a lot of help in this topic

thx

Two more question:
I want to monitor and make graphs for about 400 routers by this script. Do you think it can kill Zabbix performance?
Now scripts runs every 10min, where can I change it? I am thinking about 5min
