REST API : How to fetch HW/SW Information

General
1

Hi All,

Greetings!

I am trying to create a custom REST API integration which needs to fetch the HW/SW information of the hosts under a selective Host Folder.

host_inv_api is working fine but i want to make this work with REST API.

Thank you,

Warm Regards,

Guru

Option 1 use the CMDBSYNCER
CMDBsyncer Documentation

Option 2
is a two-step approach:

  • Step 1: Retrieve the hosts from the desired folder via the REST API.
  • Step 2: Fetch the inventory data for these specific hosts using host_inv_api.py.

This combines the best of both worlds and remains a stable solution in version 2.4.

example 
SITE="mysite"; SERVER="192.168.1.10"; USER="automation"; PASS="secret"
BASE="https://$SERVER/$SITE/check_mk"

# Step 1: getting hosts from folder
HOSTS=$(curl -s -G \
  -H "Authorization: Bearer $USER $PASS" \
  -H "Accept: application/json" \
  --data-urlencode "folder=linux~debian" \
  --data-urlencode "recurse=true" \
  "$BASE/api/1.0/domain-types/host_config/collections/all" \
  | python3 -c "import sys,json; print(' '.join(h['id'] for h in json.load(sys.stdin)['value']))")

echo "Hosts: $HOSTS"

# Step 2: Inventory inventory for this hosts
HOST_JSON=$(python3 -c "import json,sys; print(json.dumps({'hosts': sys.argv[1:]}))" $HOSTS)

curl -s -G \
  -H "Authorization: Bearer $USER $PASS" \
  --data-urlencode "output_format=json" \
  --data-urlencode "request=$HOST_JSON" \
  "$BASE/host_inv_api.py" | python3 -m json.tool

I have a script for this

CMK-exchange/helper_scripts/inv_hosts_from_folder.py at main · bh2005/CMK-exchange

no prob … but keep in mind:

#  Folderpath in CheckMK-Notation:
#   Root-Folder   → ""
#   /linux        → "linux"
#   /linux/debian → "linux~debian"
#   /locations/berlin → "locations~berlin"

if all fixed mark as solved …

@Gurusankar if you want to fetch the inventory data via REST-API you can use the Monitoring → Host status endpoint and fetch the entire HW/SW inventory. Basically this is a Live status query via REST-API.

http(s)://<your-cmk-server>:<port>/<your-site-name>/check_mk/api/1.0/domain-types/host/collections/all
