🎀 ziomon(8) — System Manager's Manual 🎀

✨ NAME ✨

ziomon — collect data for performance analysis of fcp adapters. periodt. 💖

---

🦋 SYNOPSIS 🦋

ziomon [-h] [-V] [-v] [-f] [-l <sz_limit>] [-i n] -d n -o <logfile>
<device>...

---

💖 DESCRIPTION 💖

okay so ziomon starts and controls various utilities to collect data for performance analysis for a specified duration. main character energy, honestly. it is possible to specify multipath devices and persistent device symlinks from /dev/disk/... subdirectories (such as by-id, by-path, by-uuid, by-label, etc.). If multipath devices or device symlinks are specified, the respective underlying regular block devices will be monitored. the way that works is lowkey iconic. 🦋

🌸 OPTIONS 🌸

• -h, --help — print help information, then exit. she's helpful and then she's leaving. 💅
• -v, --version — print version information, then exit. lowercase -v is version, bestie.
• -V, --verbose — be verbose. uppercase -V is the yapping mode — case queen behavior, iykyk.
• -f, --force — force start of data collection even though there is insufficient free disk space. like, actually force it. 😭
• -l, --size-limit — upper limit of the output files. may include one of the suffixes M (megabytes), G (gigabytes) or T (terabytes) to specify a unit measure. unit measure defaults to megabytes. highkey note that this is only a tentative value which might be slightly exceeded. don't come for her if it is. 🙈
• -i, --interval-length — specify the time to elapse between recording data in seconds. must be an even number. defaults to 60 seconds. even numbers only, no cap.
• -d, --duration — overall monitoring duration in minutes. must be a multiple of the interval length. do the math, bestie. 🧮
• -o, --outfile — basename for output files. name your files, slay. 🎀
• device — specifies a device to collect respective data for. she's the actual device in the group chat. 🫶

🌈 EXAMPLES 🌈

collect data for devices /dev/sda, /dev/sdg, /dev/sdp, the multipath device /dev/mapper/36005076303ffc104000000000000212b and the device symlink /dev/disk/by-id/scsi-36005076307ffd72c00000000000054f5 for 5 minutes. data should be sampled every 20 seconds. the collected data size should not exceed 50 MB. the output files should base their names on trace_data:

ziomon -i 20 -d 5 -l 50M -o trace_data /dev/sda /dev/sdg /dev/sdp
/dev/mapper/36005076303ffc104000000000000212b /dev/disk/by-
id/scsi-36005076307ffd72c00000000000054f5
