OpenBSD Inventory

if you have all your boxes inventory in json format, you can do nice things like this:

show me all boxes with php8.x installed. need version, total memory and fqdn

jq -r '.|select(.software.php |contains("8")) |
  .software.php+" "+
  .memory.total+" "+
  .system.fqdn' \
  *.json |sort -n

result

8.0 1.9GB host1.whatever
8.0 1.9GB host2.whatever
8.0 4.0GB host3.whatever
8.0 4.0GB host4.whatever
8.1 1.0GB host5.whatever
8.1 3.9GB host6.whatever

add cpu count, speed and memory free, order by free memory ascend

jq -r '.|select(.software.php |contains("8")) |
.software.php+" "+
.cpu.count+" "+
.cpu.speed+" "+
.memory.total+" "+
.memory.free+" "+
.system.fqdn' \
*.json |sort +4n

result
