Description
This article describes various methods of monitoring CPU and memory resources.
Solution
Method 1 : CLI commands
The following commands will show resource usage:
Other statistics commands:
Method 2 : SNMP polling
Use an SNMP client to monitor the FortiGate resources, CPU and memory, with the following MIB objects:
OID: .1.3.6.1.4.1.12356.101.4.1.3.0 >>>Current CPU usage (percentage).
OID: .1.3.6.1.4.1.12356.101.4.1.4.0 >>>Current memory utilization (percentage).
Method 3 : SNMP traps
Configure a SNMP community to send CPU and memory usage traps
config system snmp community edit 1 set events cpu-high mem-low fm-if-change config hosts edit 1 set ip 10.160.0.171 next end set name "LAB" next end |
Note that the thresholds can be configured:
config system snmp sysinfo set trap-high-cpu-threshold 10 set trap-low-memory-threshold 5 end |
Method 4 : Using the Event log (sent syslog and/or FortiAnalyzer)
From the GUI, go to Log&Report, and enable "CPU & memory usage (every 5 minutes)"
