The subject command, the default for the ping active service check, does not work reliably with some of my simple IoT hosts.
Nevertheless, I can use the Linux command line ping command with any of these specific hosts and that will work 100% reliably for thousands of pings.
Is there an alternative to check_mk_active-icmp, something that is more akin to the Linux command line ping?
If there is a such a command available, is there a tutorial on how it could be implemented as a custom active service check?
I’m running 2.1.0b6 raw on Ubuntu Focal.
