How to get the alert if server down.

[Tharakaw]

Hi All,
I am trying to monitor and alert if any servers are going to down. I have found some articles to alert if the server is offline using ping status. But actually, if we monitoring using ping it will trigger not only server down but also the network is unreachable. If there any way to get the alert with details like if the server is going down for some reason(crash, plan, any other reason) and who have rebooted the server, Please let me know.

Thank you.
Best Regards,
Tharaka

Are you using Zabbix agents or SNMP for the servers.

In case monitoring over zabbix agent it is possible to peak on my OS {Linux,Solaris,Windows} templates how "SYS::host is down" trigger has been implemented (important part is set of dependencies on other triggers)

Hi kloczek,
I was tried to import you said new template(OS Windows.xml) but It gives below error and failed. Can you please help me to figure out this.

Which one version of the zabbix you are using? Probably not zabbix.3.4.x
Begin of the xml file with this template has:

<?xml version="1.0" encoding="UTF-8"?>
<zabbix_export>
  <version>3.4</version>

Hi kloczek,
Thank you for your reply. My Zabbix Version is below.
zabbix_server (Zabbix) 3.4.2




Not sure why it's not supported.If it is not working if there any way to go through.

[kloczek]

Import is done over web frontend.
Are you using matching version of the web frontend?

PS. BTW. latest 3.4.x it is 3.4.11.

Hi kloczek,
I am a beginner for zabbix, Can I let me know how to verify the version of the web frontend?.
Thank you.

[kloczek]

Version of the web frontend is on each zabbix web page on the bottom.
I've checked few my files with templates exported out of older zabbix stacks and I think that you may have issue with importing zabbix templates because some php extensions are not present in php installed on web server.
If you are using some rpm based Linux like RH, CentOS, OL or other can you show me result of the command "rpm -qa | grep ^php" ?
I think that in your case php-xml may be missing.

Thank you for your extended support and the reply. I have checked with your command and it is giving below result.


And also I able to upload and used below template without an issue. I am not understand why it is not given to upload the required file.

[kloczek]

All what I can tell you is that I'm able to import this template without any issues.
Are you sure that you are using OS Windows.xml file downloaded as raw file from https://raw.githubusercontent.com/kl...%20Windows.xml of from directory where you've cloned zabbix-templates repo?
in this xml file there is no "/source" phrase

[tkloczko@domek OS Windows]$ grep \/source OS\ Windows.xml
[tkloczko@domek OS Windows]$

If you are not using raw version of the file just clone repo using command:

$ git clone https://github.com/kloczek/zabbix-templates

Additionally if you are going to use scripts included in the repo you should clone zapish repo as well:

$ git clone https://github.com/kloczek/zapish

Hi kloczek,
It was an error on the template that I was used. Currently, it is depended on some templates as ICMP and Service Zabbix Agent. If you have the link to download that template please share with me. Another thing is there is no any Item or trigger configured as "SYS::host is down" on the https://raw.githubusercontent.com/kl...%20Windows.xml
Please advice me.

Thank you.

[kloczek]

Both templates are in the same repository https://github.com/kloczek/zabbix-templates
