Hi , i try configure jasper reports with zabbix , using this procedure : https://community.jaspersoft.com/wiki/creating-and-managing-custom-reports-zabbix-jasper-reports-through-json-rpc-api#comment-850891 , i have sucesss to work , but i have problem with a number of result pages in preview (i have 34 pages of 150 hosts) . I try use trick for large relatories (https://community.jaspersoft.com/wiki/how-modify-virtualizer-settings-very-large-reports and https://notfoundexception.wordpress.com/2011/08/11/timeout-e-maxpages-no-jasperreports/ ) , but not work , i have limited number 34 of pages on compile and preview . * I think my server zabbix is slow , "have a lot process and for this is normal" , but for json (for zabbix) in case is slow is one possible problem ? Have one alterative to fix this problem i have ? Thanks yours atention. Carlos Alberto - Brasil
