It is safe to increase the trigger threshold or turn off that alarm (select “Problems” tab → left click on the alarm → select “Configuration” → remove the check from “Enabled” → hit the “Update” button)
Note that if you follow this configuration, you may receive “ Too many processes on the Zabbix server” alarm in Zabbix frontend due to the new Zabbix configuration. I didn’t have any problems with memory, but if your Zabbix server crashes because of lack of memory, reduce “ innodb_buffer_pool_size” and restart MySQL server. However, in this case, we are sharing a server with Zabbix and Apache processes so you should set innodb_buffer_pool_size to 40% of total system memory – that would be 400M because Raspberry Pi 3 B+ has 1G RAM (set 800M if you have Raspberry Pi 4 that has 2G RAM). You should set that parameter to 70% of system memory if only database is installed on server. The second most important parameter is innodb_buffer_pool_size, which determines how much memory can MySQL get for caching InnoDB tables and index data. You can use the command below to automatically check the number of Zabbix processes and add 200 to that number: :~ $ egrep "^Start.+=" /etc/zabbix/zabbix_nf | awk -F "=" ''

Save and exit the file ( ctrl+ x, followed by y and enter) and set the correct file permission: chown mysql:mysql /etc/mysql//10_my_tweaks.cnfĬhmod 644 /etc/mysql//10_my_tweaks.cnfĬonfiguration parameter max_connections must be larger than the total number of all Zabbix processes plus 200. Create custom MySQL configuration fileĬreate file “ 10_my_tweaks.cnf” with “ nano /etc/mysql//10_my_tweaks.cnf” and paste this configuration: We need to increase the maximum permitted number of simultaneous client connections and optimize MySQL – so move to the next step.Ī. If you try to start the Zabbix server you will receive an error “ connection to database 'Zabbix' failed: Too many connections” in the log “ /var/log/zabbix/zabbix_server.log” because we are using more Zabbix processes than MySQL can handle. You can find out more about the parameters supported in a Zabbix server configuration file in the official documentation.
Let’s say if you don’t use ICMP checks then set the “ StartPingers” parameter to 1 or if you don’t use active agents and active proxies then set “ StartTrappers” to 1 and so on. This is not a perfect configuration, keep in mind that you can optimize it even more. Save and exit file ( ctrl+ x, followed by y and enter). Open zabbix_nf file with command: "nano /etc/zabbix/zabbix_nf” and add this configuration anywhere in file: StartPollers=100 Step 9: Optimizing Zabbix Server (optional)ĭon’t bother with this optimization if you are monitoring a small number of devices, but if you are planning to monitor a large number of devices then continue with this step.
