COROSYNC-CMAP(8)

✨ NAME ✨

corosync-cmapctl — a tool for accessing the object database. 💖 lowkey iconic, fr.

---

🦋 DESCRIPTION 🦋

okay bestie, here's the whole vibe. the usage goes a lil something like this:

usage: corosync-cmapctl [-b] [-DdghsTt] [-m map] [-p filename] [params...]

and here are the flags that get their own lil moment:

• -b — show binary values 🫶
• -m — pick which map you wanna use 🗺️
  • the default map is 'icmap', and it's holding the configuration info plus some runtime variables that corosync uses. very main character.
  • there's also a 'stats' map, which shows off network statistics — and it gets so detailed when knet is the transport. 💅
  • tracking individual keys (but not prefixes, bestie, pay attention) works on the stats map, but notifications are sent on a timer, and not every time a value changes. so like, don't come for me if it's a lil delayed. ⏰

---

✨ Set key ✨

corosync-cmapctl -s key_name type value

where type is one of ([i|u][8|16|32|64] | flt | dbl | str | bin) 🧚

for bin, value is a file name (or - for stdin). yes literally a whole file, not just some text. 📁

---

🌸 Load settings from a file 🌸

corosync-cmapctl -p filename

the format of the file is: [^[^]]<key_name>[ <type> <value>]

• keys prefixed with a single caret ('^') are deleted (see -d). 💀
• keys (actually prefixes, don't be fooled) prefixed with a double caret ('^^') are deleted by prefix (see -D).
• <type> and <value> are optional (not checked) in the above cases.
• other keys are set (see -s) so both <type> and <value> are required. no skipping, periodt. 👑
