gather performance graph in bulk for all monitored hosts

[borgliu]

HI all,
I am new for Nagios, I installed and configed Nagiox XI and monitoring 100+ linux/windows hosts
Nagios XI do provide performance data in graph for each monitored host, I can see CPU usage, memory usage, disk usage and so on
in order to provide reports, I can download graphics in PNG/JPG or PDF format for each host (see picture below)
however, download it one by one for each host is not practicable since I have 100+ hosts .

is anyway to download the generated graph in bulk? I want to download all CPU usage(and memory, disk, bandwidth) graphics for all my 100+ host in bulk
either any plug-in, tools, or scripts can do so? I try to google but maybe use wrong keyword so no lucks

I don't know of a way but you might look at rrdtool to see if it might help.
