FG 620B Hi CPU Usage by ipsengine and dnsprosy services

Hi

I have problem with my FG620 A-P Cluster.

What ive noticed is that my CPU alvays at the same point  between 90 and 1005 of usage

Run Time:  6 days, 21 hours and 28 minutes 35U, 0N, 63S, 2I; 2016T, 1088F, 141KF         dnsproxy      115      R      58.0     1.1            snmpd       95      R      37.0     0.5          miglogd       66      S      18.6     1.6          src-vis      103      S       3.6     1.9            ospfd       57      R       1.4     1.9           dhcprd       97      S       0.8     0.5           httpsd     3882      S       0.4     3.9          sslvpnd       86      S       0.4     1.3             iked       93      S       0.2     1.2           hasync       99      S <     0.2     0.6              dsd      126      S       0.0     5.5          pyfcgid     4311      S       0.0     3.1          pyfcgid     4313      S       0.0     3.1          pyfcgid     4312      S       0.0     2.8           httpsd     3879      S       0.0     1.8          cmdbsvr       48      S       0.0     1.5           httpsd     5015      S       0.0     1.3      proxyworker       94      S       0.0     1.1          pyfcgid     4309      S       0.0     1.1        scanunitd      124      S <     0.0     1.0 at the time i stopped IPSENGINE service (diagnose test app ipsengine 98) becouse traffic between internet and lan almost stopped

how can i check which policy, host or feauture (or something) uses the most CPU and memory?
