Hi there,

Just wondering why the send function has been removed? and how I'm supposed to send the output over to zabbix?

I know I'm a bit behind the times with this question, but i've been using a version from years back to monitor varnish 4x and just got round to having a play with varnish 6.

Cheers,
Benny

Hello all, When i run the zabbix-varnish-cache.py file i get the following error. After the error all looks fine but zabbix complains about the output not beeing JSON.

root@varnish-staging:/usr/local/bin # ./zabbix-varnish-cache.py -i '' send -c /usr/local/etc/zabbix/zabbix_agentd.conf

Hi, When I try to execute the python script I'm presented with the following error, can someone help?

Hi, in 5.0.4 i have
Cannot read JSON: Syntax error.

Hi thank you for the special script,

I have one question about value of the item .

zabbix 2.x
Varnish 4.1.x

If I execute this command , some item is failed.

/usr/local/sbin/varnish_status.py send -c /etc/zabbix_agent.conf -z ZabbixServerIP -s Hostname

info from server: "processed: 73; failed: 26; total: 99; seconds spent: 0.000917"
sent: 99; skipped: 0; total: 99

How can I checked what failed items?

I already set the templates.xml in the zabbix server.

best regards

Running the discovery manually produces this output

[root@e ~]# /usr/local/bin/zabbix-varnish-cache.py -n e.varnish.web.tv2net.dk discover backends
{
"data": []
}

It looks like the regex in discovery->backends doesn't like our backend names ?!

Name after "service varnish restart"
"VBE.boot.web17.beresp_bodybytes":

Name after "service varnish reload"
"VBE.reload_2016-03-15T11:08:18.web17.bereq_bodybytes":

Sorry for troubling you - I've got a question for the send option.

zabbix-varnish-cache.py line 115

row = '- varnish.stat["%(key)s"] %(tst)d %(value)d\n' % {

What is the idea with the - infront of varnish.stat? To add a delimiter for a cut option?

Thanks,
Kristian

Are you aware of any problems arising from an upgrade to version 3.4.? I haven't investigated it yet, but no data is received by zabbix server since this upgrade.

info from server: "processed: 0; failed: 229; total: 229; seconds spent: 0.002343"

For security reason I don't have acces to file /var/lib/varnish/lab1//_.secret
There is a way to skip this file in zabbix-varnish-cache.py ?

zabbix@lab /var/lib/zabbix/externalscripts $ ./zabbix-varnish-cache.py -i '' discover backends
Cannot open "/var/lib/varnish/lab1//_.secret": Permission denied

Hi there !
Trying to run /usr/local/bin/zabbix-varnish-cache.py ,
I got the following error:
/usr/local/bin/zabbix-varnish-cache.py
File "/usr/local/bin/zabbix-varnish-cache.py", line 239
for key, value in result.items()
^
SyntaxError: invalid syntax

I'm running python 2.3 on centos 6.4

Sorry to fork another ticket. I am having similar issues still. Please see these 2 screenshots.
you can see items are correctly passed and processed at server end too. http://prntscr.com/l6gqjk
But still no data at zabbix front end. http://prntscr.com/l6gr42
Please assist me.

Hi Guys,

Really liking the look of this project. I've made the fix outlined in #6 and the script is returning nicely.

I noticed I'm getting:

info from server: "processed: 0; failed: 89; total: 89; seconds spent: 0.000542" sent: 89; skipped: 0; total: 89

Running the command as:

/usr/local/bin/zabbix-varnish-cache.py -i '' send -c /etc/zabbix/zabbix_agentd.conf -s hostname``

The Zabbix (3.0) Front-end says the value needs to be valid JSON. I put the server into debug and captured what the host was sending and the output looks fine in a JSON validator.

This is the user params entry:

[root@cache-01 ~]$ cat /etc/zabbix/zabbix_agentd.d/userparameter_varnish.conf UserParameter=varnish.discovery[*],/usr/local/bin/zabbix-varnish-cache.py -i '$1' discover $2

The only thing I'm not too sure on is the $VARNISH_CACHE_LOCATIONS macro. I saw the host has inherited this macro from the template and it doesn't have a value, but the instructions say this should be blank if there is only one Instance running on the server. Does this mean to just leave it without a value?

Thanks,

Anton

Hi,
I had to change the cron job from -s dev to -s $HOSTNAME for it to work properly.
Is this a but or just something not specified in the readme ?

Cheers,

Jef

I want to monitor, discovery rules but, when i try to give {$VARNISH_CACHE.LOCATIONS} => /var/lib/varnish/; Zabbix already says "Unsupported Item key" for Discovery rules. Which location did i define for this macro.

Thanks for your help.

I know this script is for Zabbix 2.4 but in case you plan to upgrade to v3, if you have encryption enabled on the server then the zabbix_sender needs to be configurable with the necessary parameters.

Sorry i couldn't make it work so far.
My Zabbix server version is 3.4.7, varnish version is 4.1 and i am using correct 4.1 branch files.
Varnish discovery is enabled. http://prntscr.com/l5gak1
I have added "UserParameter=varnish.discovery[*],/usr/local/bin/zabbix-varnish-cache.py -i '$1' discover $2" in /etc/zabbix/zabbix_agentd.conf of varnish server
But when i run /usr/local/bin/zabbix-varnish-cache.py python script, it shows me the following error.

Checked cron log, zabbix agent log on the client and it seems everything is setup correctly but I don't see any data collected. On the server side every item related with Varnish is enabled except Varnish- Cache hit ratio.

Hello Support,

I have followed installation guide. I setup following cron job on zabbix client/Varnish server.

• • • • • /usr/local/bin/zabbix-varnish-cache.py -i <varnish_host> send -c /etc/zabbix/zabbix_agentd.conf -z -s > /dev/null 2>&1

But On Zabbix server, i can see varnish raw log is not running & Varnish NCSA log is not running. please see here http://prntscr.com/l3i5ek

When i run the python script manually at Varnish server/Zabbix client end, i got these errors

Hello,

Thanks for the script. I tried and Varnish items discover works just fine but I've got an error both backend discovery and storage discovery. I use Zabbix 3.4.9 and Varnish 4.0.5. Cron output is below. Could you please help me out?

Sorry, but i can't started script

root@debian:~# sudo -u zabbix sudo /usr/local/bin/zabbix-varnish-cache.py --varnish-instances 127.0.0.1 stats
.....
Could not get hold of varnishd, is it running?
.....
Could not get hold of varnishd, is it running?

I added string to sudoers
zabbix ALL= (ALL) NOPASSWD: /usr/local/bin/zabbix-varnish-cache.py

and

chmod +x /usr/local/bin/zabbix-varnish-cache.py,
sudo usermod -a --groups varnish zabbix,
sudo usermod -a --groups varnish root

and not working. What I need doing else?
Thanks
