biolatency and tcpretrans BCC tools fail during melisai collect

[patsevanton]

I’m running melisai collect with the quick profile and see failures from the embedded BCC/eBPF tools:

sudo melisai collect --profile quick -o report.json

Status

tcpretrans fix: PR #20 — the tool doesn't accept duration as positional arg. Fixed for 22 event-based tools total.

biolatency: This is a bcc-tools version issue, not melisai. Your bpfcc-tools package is too old for your kernel.

blk_account_io_done was inlined in kernels 5.17–6.5 (bcc#4638). The upstream biolatency.py already has auto-detection for tracepoints, but distro packages lag behind.

Workaround: install bcc from source or PPA:

# Ubuntu — use iovisor PPA
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4052245BD4284CDD
echo "deb https://repo.iovisor.org/apt/$(lsb_release -cs) $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/iovisor.list
sudo apt-get update && sudo apt-get install bcc-tools libbcc-examples python3-bcc

Or install from pip: sudo pip3 install bcc
