zabbix interview questions
Top zabbix frequently asked interview questions
I have notifications coming back from web scenarios that say "PROBLEM' and "OK". I would like to include the content of the web response when a problem happens. I'm not worrying about header values, just the content of the web page. Is this a variable I can reference in the Notification setup?

Our team now uses zabbix for monitoring and alert. In addition, we use fluent to gather log to an central mongoDB and it is put to work for a week. Recently we were discussing another solution - Logstash. I wanna ask which difference between them? In my opinion, I'd like use zabbix as a data-gathering and alert-sending platform and fluent plays the 'data-gathering' role in the whole infrastructure. While I've looked into Logstash website and found out that Logstash is not only a log-gathering system, but also a whole solutions for gathering, presentation and search.
Would anybody can give some advice or share some experience?

To configure on the server and fronted. But to run on agents:
- Some simple unix commands, to obtain our reporting data.
- When there is some processing required on the agent side.
There seem to be a variety approaches being talked about. So how to execute such commands on a zabbix agent?

Good day. Using net.if.in and net.if.out keys I'm getting total amount of bytes transferred through a network interface. If I store value as delta I'll get speed per second. Is there a way to get amount of data transfered each day and week? Thank you in advance. Vojta

I have the following default chart in zabbix, but I have no idea how to interprete these values. Can anyone explain?

Here is my goal: I would like to be able to report various metrics to zabbix so that we can display the graphs on a web page.
These metrics include:
- latency per soap service submission
- various querie results from one or more databases.
What things do I need to write and/or expose? Or is the zabbix server going to go and get it from an exposed service somewhere?
I've been advised that a script that returns a single value will work, but I'm wondering if that's the right way.

My Goal:
I would like to extract graphs associated with hosts in .png format. My GOOGLE research say's we don't have Zabbix API designed to do this task. So few blogs advised to user Chart2.php & CURL. Can someone explain me how to go about it ( detailed steps )?
Note: Sorry never worked on php nor on curl
When i tried
curl https://example.com/zabbix/chart2.php?graphid=1552&width=300&height=300
Got this, but link doesn't work
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

I can't open the zabbix frontend URL via
http://zabbixservername/zabbix
Error 404 is given:
Not Found
The requested URL /zabbix was not found on this server.
Apache/2.4.7 (Ubuntu) Server at ipaddress Port 80
I'm running Ubuntu 14.04 LTS (GNU/Linux 3.13.0-27-generic x86_64)
I installed Zabbix server following Zabbix instructions for Ubuntu 14.04 at:
https://www.zabbix.com/documentation/2.2/manual/installation/install_from_packages
(bottom section of the page)
Though the follwowing file was not created:
/etc/apache2/conf.d/zabbix.conf
But I did edit regional settings in:
/etc/zabbix/apache.conf
After that I also copied the apache.conf to /etc/apache2/conf.d/zabbix.conf
restarted apache, but gave no result
Apache is running; when I go to http://zabbixservername/, I get the Apache default welcome page.
Also zabbix-server process is running on the server.
This is what the Apache acces.log says when I try to enter the frontend http://zabbixservername/zabbix
[04/Jun/2014:14:42:54 +0200] "GET /zabbix HTTP/1.1" 404 494 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.114 Safari/537.36"
I would guess the problem lies somewhere within the communication between Apache and Zabbix?
If so... I don't know how to check and/or fix that...
Looking for some guidance here.
Additional information can be provided.

I have values in a Zabbix DB that are loaded onto it every minute. I need a query that computes hourly totals for different days e.g under 20 Mar 2013, I'd have a row for 0:00 containing a sum of values where time >= 0:00 and < 1:00 and so on. Then I'd have another row for between 1 and 2 AM etc. I am using the query below, but I have to keep changing the times. What I am looking for is a query that will generate for me 24 rows for each hour period in a day. Please help.
SELECT
SUM(CASE WHEN itemid = 23661
THEN value ELSE 0 END) Hits
FROM history_uint WHERE
clock >= EXTRACT(EPOCH FROM TIMESTAMP '2013-03-24 00:00:00')
AND clock < EXTRACT(EPOCH FROM TIMESTAMP '2013-03-24 01:00:00')

From the Zabbix Manual
the calculated items expression follows the form,
func(<key>|<hostname:key>,<parameter1>,<parameter2>,...)
This is fine for computations using functions over a single item like,
max("temp1",120)
How should a function like min() be applied over 3 different items so it returns the lowest of those?

I need to see what memory size, CPU usage and so on for my application, found zabbix as monitoring tool and want to create bridge between zabbix and my app. I do not want to add additional module with JMX MBeans. Are there some implementations/solution for creating bridges ? I wanna copy some jar/jars o my class path and see general monitoring information.
Thank a lot.

I have problem with the setup of zabbix agent on my Ubuntu 10.04 (lucid) server. I have zabbix server on other server and I configured hosts in server and agent how it should be (used zabbix manual), but Zabbix server cannot connect to agent and gives error:
Get value from agent failed: cannot connect to [[{server IP where is agent}]:10050]: [4] Interrupted system call
Server doesn't have a firewall that can create this problem and port is opened.
I very apreciate any help!

Our web application sends e-mails. We have lots of users, and we get lots of bounces. For example, user changes company and his company e-mail is no longer valid.
To find bounces, I parse smtp log file with log parser.
Some bounces are great, like 550+#5.1.0+Address+rejected+user@domain.com. There is user@domain.com in bounce.
But some do not have e-mail in error message, like 550+No+such+recipient.
I have created simple ruby script that parses logs (uses log parser) to find which mail caused something like 550+No+such+recipient.
I am just surprised that I could not find a tool that does it. I have found tools like zabbix and splunk for log analysis, but they look like overkill for such simple task.
Anybody knows a tool that would parse smtp logs, find bounces and e-mails that cause them?
Edit: smtp server is microsoft smtp server.
