5220 Limits

I have a 5220 ver 2.5.3 running Netbackup 7.5.0.6. I want to know of there is a way I can monitor my appliance to know if I am reaching limits with it in regards to amount of policys run at one time. I run into jobs running that fail and have been trying to run them at different times to find out if I have a bottleneck. But if there is a tool to monitor performance of my 5220 and tell me I'm running too hot, that would be great.
