When percpu is True returns a list of floats representing the utilization as a percentage for each CPU. In this case it is recommended for accuracy that this function be called with at least 0.1 seconds between calls. That means the first time this is called it will return a meaningless 0.0 value which you are supposed to ignore. When interval is 0.0 or None compares system CPU times elapsed since last call or module import, returning immediately.

When interval is > 0.0 compares system CPU times elapsed before and after the interval (blocking). Return a float representing the current system-wide CPU utilization as a percentage. Psutil.cpu_percent(interval=None, percpu=False) Individual CPUs: 11.00% 8.50% 11.90% 8.50% 9.90% 7.60% 11.50% 12.30%įor more information on how the psutil.cpu_percent(interval=2) python call works, see the official psutil.cpu_percent(interval=None, percpu=False) documentation here: Sample output: notice that I have 8 cores, so there are 8 numbers after "Individual CPUs:": Total: 10.15% printf "%b" "import psutil\nprint(''.format(' '.join(cpu_percent_cores_str)))\n\ This calls python3 and uses the cross-platform psutil module. There, select as Host Check Command the Use the status of the service…​ option and enter Internet connection as its name - the same name you chose as the service name in the previous step.Do this to see the overall CPU usage.

Under Monitoring agents, enable Checkmk agent / API integrations and select No API integrations, no Checkmk agent there.Ĭreate a new rule from the Check hosts with PING (ICMP Echo Request) rule set that only applies to the new host internet (for example, via the Explicit hosts condition, or a matching host tag).Įnable Service Description and enter Internet connection.Įnable Alternate address to ping and select Ping all IPv4 addresses there.Įnable Number of positive responses required for OK state and enter 1.Ĭreate another rule that also only applies to the host internet, this time from the Host Check Command rule set. Under Additional IPv4 addresses enter the remaining IP addresses. Select several computers on the Internet that should normally be reachable via a ping command and note their IP addresses.Ĭreate a new host in Checkmk, for example with the name internet and configure it as follows:įor IPv4 address enter one of the noted IP addresses.
