mod_cache_disk in 2.4. All load balancing implementations have been moved to individual, self-contained mod_proxy submodules, e.g. mod_lbmethod_bybusyness. You might need to build and load any of these that your command 'User', perhaps misspelled or defined by a module not included in the server configuration - load module mod_unixd Invalid command 'Require', perhaps misspelled or defined by a module not included command 'Order', perhaps misspelled or defined by a module not included in the server configuration - load module mod_access_compat, or update configuration to 2.4 authorization directives.

at the weekly temperatures in the server room for the last two months? Have to compare webserver load for the first month of every quarter this year? All that and more is possible with this new feature and above setups. 4.1 Performance improvements When monitoring hundreds and thousands of devices, load on the monitoring server hardware can become a serious issue. Zabbix 1.8 brings many different improvements index resolving and data retrieval is performed in a single connection now, reducing network load and load on the monitored devices. 4.2 Automated host management improvements For larger or constantly
