Get usage stats for a cloud.gov application

get-app-guid.sh

#!/bin/bash

#

# The GUID for the app you want to check
APP_NAME=$1 

if [[ ! $(which jq) ]]; then
  echo "Error: You must have the jq utility installed to run this script. https://stedolan.github.io/jq/" >&2

cf curl "/v2/apps" -X GET -H "Content-Type: application/x-www-form-urlencoded" -d "q=name:$APP_NAME" | jq '.resources | .[].metadata | .guid'

MEM_UTIL=$(printf '%.*f\n' 2 $(cf curl "/v2/apps/$APP_GUID/stats" | jq '((.[].stats | .usage | .mem) / (.[].stats | .mem_quota)*100)'))
DISK_UTIL=$(printf '%.*f\n' 2 $(cf curl "/v2/apps/$APP_GUID/stats" | jq '((.[].stats | .usage | .disk) / (.[].stats | .disk_quota)*100)'))

echo -e "\n"
echo "Usage stats for app: $APP_GUID"
echo "------------------------------------------"
echo "Allocated memory utilization: $MEM_UTIL"

The get-app-guid.sh script can probably be replace by just doing:

~$ cf app <APP_NAME> --guid
