Hello, I have a SRX 4100 and high CPU "spikes"
While troubleshooting, I realised that mib2d & snmp take much utilization, & research showed me that our Check_MK plugin does snmpwalks and that may cause our high CPU, so I temporarly deactivated our plugin for Check_MK and monitored it manually with snmpgets and the CPU spikes were instantly less.. But still there are spikes above 90 percent
Running following commands:
