Zabbix History Table Clean Up

Zabbix history table gets really big, and if you are in a situation where you want to clean it up. Then we can do so, using the below steps. Stop zabbix server. Take table backup - just in case. Create a temporary table. Update the temporary table with data required, upto a specific date using epoch . Move old table to a different table name. Move updated (new temporary) table to original table which needs to be cleaned-up. Drop the old table. (Optional) Restart Zabbix Since this is not offical procedure, but it has worked for me so use it at your own risk. Here is another post which will help is reducing the size of history tables - http://zabbixzone.com/zabbix/history-and-trends/ Zabbix Version : Zabbix v2.4 Make sure MySql 5.1 is set with InnoDB as innodb_file_per_table=ON Step 1 Stop the Zabbix server sudo service zabbix-server stop Script. echo "------------------------------------------" echo " 1.

Installing Zabbix Version 2.4 Offline (Zabbix Server without Internet).

There might be situations where you have a remote/zabbix server which does not have internet connectivity, due to security or other reasons. So we create a custom repo on the remote/zabbix server so that we can install zabbix using rpms Here is how we are planning to do this. Download all the dependency rpms on a machine which has internet connection, using yum-downloadonly or repotrack . Transfer all the rpms to the remote server. Create a repo on the remote server. Update yum configuration. Install. NOTE: This method can be used to install any application, but here we have used zabbix as we had this requirement for a zabbix server. Download dependent rpms . On a machine which has internet connection install the package below. And download all the rpms . Make sure the system are similar (not required to be identical - At-least the OS should be of same version) mkdir /zabbix_rpms yum install yum-downloadonly Downloading all the rpms to location /zabbix_rpms/ ,...
