Sample error,

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 35 bytes)

Workaround

Increase PHP’s memory limit, either by adding:
memory_limit = 20M to your php.ini file (recommended, if you have access)
ini_set(’memory_limit’, ‘20M’); in your sites settings php file
php_value memory_limit 20M in your .htaccess file

The memory can adjust more than 20MB according to needs.

It just a tools that let you enter some build in variable to monitor your system. Such as hdd space, system loading, monitor logs, and etc. Browse to Conky main page for more information need.

Simple installation step by fire to your terminal with following command,
