Well what's hot nowadays in Linux is bpftrace which is built on top of eBPF. You probably can just 'apt install bpftrace' on your ubuntu18.04 which *may* be a bit outdated. Afterwards you can check out existing scripts, for example on my ubt 20.04: sean@ubuntu:/usr/sbin$ ls *bt bashreadline.bt capable.bt killsnoop.bt opensnoop.bt statsnoop.bt tcpconnect.bt threadsnoop.bt biolatency.bt cpuwalk.bt loads.bt pidpersec.bt swapin.bt tcpdrop.bt vfscount.bt biosnoop.bt dcsnoop.bt mdflush.bt runqlat.bt syncsnoop.bt tcplife.bt vfsstat.bt biostacks.bt execsnoop.bt naptime.bt runqlen.bt syscount.bt tcpretrans.bt writeback.bt bitesize.bt gethostlatency.bt oomkill.bt setuids.bt tcpaccept.bt tcpsynbl.bt xfsdist.bt
There are some resemblance between bpftrace and dtrace scripts so you might be able to adapt what you need to bpftrace.
