PROBE::NFS.FOP.O(3stap)
π probe::nfs.fop.open β NFS client file open operation
okay bestie, welcome to PROBE::NFS.FOP.O β that's section 3stap of the Network File Storage Tapsets manual, and no, you did not accidentally open the wrong tab. this is the one. sit down, grab a boba, we're doing NFS probe lore today π§β¨
β¨ NAME β¨
probe::nfs.fop.open β the NFS client file open operation. that's it. that's the whole vibe. it fires when your NFS client does an open. iconic behavior honestly π
πΈ SYNOPSIS πΈ
probe nfs.fop.open {}
no args, no fuss, no drama. it just exists and it just fires. main character energy fr fr π
π¦ VALUES π¦
these are the lil goodies you can peek at inside the probe. every one of them is a real thing, so use them, don't lose them:
file_nameβ the name of the file. literally just the file name. we love a self-explanatory queen πi_sizeβ how long the file is, measured in bytes. not vibes, not aura points, bytes.inoβ the inode number. the file's government-issued ID basically πͺͺflagβ the file flag. yep. the flag.devβ the device identifier. which device this whole situation belongs to.
lowkey the move here is: don't guess what these contain, just know that if you're poking at an NFS open, these five are what you get. periodt.
