Download Zabbix
Lex Mumphrey
So I bring up a nice shiny new zabbix instance, say, running Zabbix 5.4. I apply the official Linux templates for 5.4, since it's a good place to start, and over the next few months, I modify parts of the template-- change the Severity level on some entries, maybe tweak a couple of entries to use avg() instead of last() to smooth out some of the noise in alerts. Everything's happy.
I found a template ( -app/pi-hole-api) that should allow monitoring of tons of data available thru the pi-hole api. I have added the two servers as hosts in zabbix, and installed the template, and have the template associated with the two servers, and added the API key as the template directions instruct. But I get graphs with no data. My suspicion is that this is because zabbix doesn't really know how to talk to the server, as defined. I know this is due to my ignorance, but I can't quite understand how that's supposed to happen. Am I required to install zabbix agent software on the pi-hole server? If so, this wasn't clear (to me, an admitted n00b) from the linked page above. If not an agent, how do I fill in the Interfaces section of the host configuration page? I'm guessing that zabbix can't expect an agent everywhere, so there must be some other way. I also see a template for brocade, but surely there's no expectation that I'm going to install an agent there, right? Any help, including links to useful "getting started, but not monitoring normal servers" documentation would be helpful.
Lastly install the missing components needed to run Zabbix again
apt-get install --only-upgrade zabbix-server-mysql zabbix-frontend-php zabbix-agent zabbix-apache-conf
apt-get install zabbix-server-mysql
apt install php
apt install php-gd php-ldap openipmi fping php-mbstring php-bcmath
I looked up zabbix in the options for configuration.nix and found a lot.Most promissing looking was services.zabbixServer.enable. I set that to true in my config and rebuilt it. This seems to have worked:
The error message indicates that services.zabbixWeb.virtualHost is used but not defined. The solution to this is most likely to define a value for that option. You can find the documentation for services.zabbixWeb.virtualHost here:
if some of the items are updating, and some are not, there must be some difference between them. could it be that some are zabbix passive items, and some are active items ? if so, figure out why some category has stopped working.as you have added, querying for items is working, so maybe they have been set to be active items ? you can see that in item properties.
Note: I did try docker-compose --profile=all -f docker-compose_v3_alpine_mysql_latest.yaml logs but I get no mention of the image/container for zabbix-docker_db_data_mysql_1. Is there a way to filter the logs by image that is not grep?
I can't speak for the Windows agent (haven't used it and don't plan to), but all of the Unix-like agents as well as the server give up their root permissions and live their lives as a non-privileged user. This is table stakes these days as far as security goes, but all the same, it demonstrates thoughtfulness and forethought to engineer the software such that it does not require root privileges to perform its duties. As you can see below, there isn't even a priveleged parent process; all process are running as the regular user _zabbix.
One thing I've struggled to find is a web-accessible version of their source code repository. It appears they use SVN as their SCM of choice but their repo (svn://svn.zabbix.com) does not appear to have a web-based front end for browsing the repo, history, diffs, etc. Even looking to Github fails because what looks like the official git mirror of the SVN repo is empty.
Parameter zabbix_host can be set with multiple hostnames separated by commas.Hostnames (or IP addresses) can be followed by colon and port number. If a portnumber is not present module will use the port number defined in zabbix_port.
Hi,
We want to trial Zabbix but so far, it has been impossible.
We tried with the ISO first but after booting up it was stuck with an error message:
-...due-to-timeout Opens a new window
"Been trying for 2 days to get an install to work, keep getting the centos stream 8-stream started then get Service org.fedoraproject.anaconda.modules.storage has failed to start: Failed to activate service 'org.fedoraproject.anaconda.modules.storage': timed out ( service_start_timeout=6000000ms)"
After: we tried with the OFV.... but it was not build for VMware but for virtual box .... so we had to modify the ovf file to fix all that was incompatible... and then we also got stuck at many errors post boot.
-ov...-hardware.html Opens a new window
Didn't work
So we then went with the Vmware .vmx but it wasn't compatible with Vcenters but for VmWare workstation so we needed to convert it fist and then this one also didn't work and now my techs are trying to fix the postgress errors in that "appliance).
We then decided to abandon the "pre-package easy appliance route" and we also build a CentOS from scrach and tried installing it manually on it ... my techs are trying to fix issues like
connection refused - database error
1174:20210819:141854.648 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111)
1174:20210819:141854.649 database is down: reconnecting in 10 seconds
So how can we make it work easily and fast: kind of tired trying to trial this software.
Thanks
We are using vmware Vcenter 5.5 and quite surprise that they couldn't make an out of the box working appliance.
Just a suggestion, don't use CentOS. Go with a distro that's still going to be supported such as Alma Linux (or any of the others out there). CentOS 7 is EOL in 2024. CentOS 8 is EOL end of this year.
-zabbix-server-centos-8/ Opens a new window
Procedure is the same for Alma 8 as it's fully compatible. Likewise for Oracle Linux, Rocky Linux, etc. that are based off Redhat.
I have already installed zabbix agent on commserve server and everything is good
but I did not find any template to integrate it, for example the controllers of the teches... the state of the backups..
I did PCAP and it looks like proxy is trying to send something, but it doesn't get to zabbix. Should I configure all SNMP ports on ASG to 161? Like receiver etc.
Source IP is my ASG, DST is Zabbix.
