PROBE::NFSD.LOOKUP(3stap)

πŸ’… probe::nfsd.lookup

okay so bestie, welcome to the 3stap manual β€” yes, that's the section, we're in the SystemTap tapset pages and honestly? iconic. This one lives in the Network File Storage Tapsets family and it's all about the NFS server doing its little errand: opening or searching a file on behalf of a client. πŸ¦‹


✨ NAME ✨

probe::nfsd.lookup β€” the NFS server opening or searching a file for a file for a client, fr fr. πŸ‘‘


🌸 SYNOPSIS 🌸

probe nfsd.lookup {}

no args, no drama, she just exists and fires. periodt. πŸ’…


πŸŽ€ VALUES πŸŽ€

these are the variables you get to peek at inside the probe, bestie β€” memorize them, they're giving main character energy:

  • fh β€” the file handle of the parent dir. heads up tho: the first part of it is the length of the file handle, so it's not just the handle, okay? read the whole thing. 🫢
  • client_ip β€” the ip address of the client. yes, THE client. the one we're doing all this for. 🌈
  • filelen β€” the length of the file name. just the length. not the name. do not confuse them, i'm begging. 😭
  • filename β€” the file name itself. there she is. the moment. the icon. ✨
