cf-sli

Prerequisites

• Stable CF CLI
• Config file (see sample below)
• Datadog Account (if you would like to send metrics somewhere)

Sample config file

cat > .config
{
  "api": "api.example.com",
  "user": "cf-sli",
  "pass": "abc123",
  "org": "cf-sli",
  "space": "dev",
  "domain": "example.com"
}

Run, extract metrics, and post to datadog

output=$(cf-sli)
stats=$(echo -e "$output" | tail -n 1) # extract last line to ignore cf cli output
app_route=$(echo $stats | jq .app_route)
app_start_time=$(echo $stats | jq .app_start_time_in_sec)
app_stop_time=$(echo $stats | jq .app_stop_time_in_sec)
app_start_status=$(echo $stats | jq .app_start_status)
app_stop_status=$(echo $stats | jq .app_stop_status)

currenttime=$(date +%s)

echo "Sending metrics to datadog..."

post_to_datadog () {
  local metric=$1
  local data_point_time=$2
  local data_point_value=$3
  local tag=$4
