Usage:
  check_podman [--image IMAGE] [-w COUNTER] [-c COUNTER]
  check_podman --block-in [-b,-k,-m,-g] [--image IMAGE] [-w COUNTER] [-c COUNTER]
  check_podman --block-out [-b,-k,-m,-g] [--image IMAGE] [-w COUNTER] [-c COUNTER]
  check_podman --cpu [--image IMAGE] [-w COUNTER] [-c COUNTER]
  check_podman --memory [-b,-k,-m,-g] [--image IMAGE] [--perc] [-w COUNTER] [-c COUNTER]
  check_podman --net-in [-b,-k,-m,-g] [--image IMAGE] [-w COUNTER] [-c COUNTER]
  check_podman --net-out [-b,-k,-m,-g] [--image IMAGE] [-w COUNTER] [-c COUNTER]
Options:
  -i, --image IMAGE   limit the investigation only to the containers running IMAGE
  -l, --block-in  return the block input metrics
  -C, --cpu       return the cpu percentage metrics
  -L, --net-out   return the block output metrics
  -M, --memory    return the runtime memory metrics
  -n, --net-in    return the network input metrics
  -N, --net-out   return the network output metrics
  -p, --pids      return the number of PIDs
  'b,-k,-m,-g     show output in bytes, KB (the default), MB, or GB
  -%, --perc      return the percentages when possible
  -a, --varlink-address ADDRESS   varlink address (default: unix:/run/podman/io.podman)
  -w, --warning COUNTER    warning threshold
  -c, --critical COUNTER   critical threshold
  -h, --help      display this help and exit
  -V, --version   output version information and exit
Note:
  Podman stats will not work in rootless environments that use CGroups V1.
  Rootless environments that use CGroups V2 are not able to report statistics
  about their networking usage.
Examples:
  check_podman -w 100 -c 120
  check_podman -i "docker.io/library/nginx:latest" -c 5:
  check_podman --block-out -m
  check_podman --cpu
  check_podman --memory -k --perc
  check_podman --memory -m --image "docker.io/library/nginx:latest"
  check_podman --net-in -k --image "docker.io/library/redis:latest"
  check_podman --pids --warning 8:
