Move host to another folder via HTTP API

[artem.timchenko]

Hi all.
I’m using Checkmk 1.6.0p22 and I’m trying to figure out if it’s possible to move host into another folder using HTTP API. I’ve tried using edit_host command, but seems like it doesn’t allow to modify neither folder nor path.

Hi Artem,
I don’t have an example for the 1.6 web api but using the 2.0 REST-API, you can use the following example from within bash:

function movehost {
src=$1
hst=$2
tgt=$3
secret="$(cat $OMD_ROOT/var/check_mk/web/automation/automation.secret)"

# Abruf eines Hostes, hier z.B. für ETag Auslesen
etag="$(curl \
    -k -i -I -s -X 'GET' \
    --header "Authorization: Bearer automation ${secret}" \
    "https://localhost/${inst}/check_mk/api/1.0/objects/host_config/${hst}" \
    | grep "ETag: " | cut -d " " -f 2 | tr -d "\"\r\n" )"

if [ -z "${etag}" ]; then
    echo "No Etag found or host not found"
    exit 2
fi

#echo "E${etag}E"

# Host verschieben
out=$(curl \
    -k -s -X 'POST' \
    "https://localhost/${inst}/check_mk/api/1.0/objects/host_config/${hst}/actions/move/invoke" \
    --header "Authorization: Bearer automation ${secret}" \
    --header "Accept: application/json" \
    --header "Content-Type: application/json" \
    --header "If-Match: $etag" \
    --write-out "\move-status_code=%{http_code}\n" \
    --data "{ \"target_folder\": \"${new_folder}\" }")

resp=$( echo "${out}" | grep "move-status_code" | cut -d "=" -f 2)
if [ "$resp" != "200" ]; then
    echo "FAILED: ${resp} ${out}"
    exit 1
fi
echo "OK"  

}

Hi,
it’s not possible to move the host from one folder to another using the HTTP API. If you update to Checkmk 2.0 you can use the REST API - as @gstolz mentioned.

Thanks for your replies, I’ll definitely consider updating to 2.0.

Just one thing to mention, I’ve tried to simply recreate host under new path:
delete host → add it with the same name and IP but under new path → run service discovery → apply
and I’ve noticed old metrics are displayed fine with such approach. Is this expected? I mean, Checkmk doesn’t delete metrics immediately after host is deleted and they could be reached from a new host with the same hostname and IP?

Hi @artem.timchenko, welcome to the forum!

Indeed, that is expected. The default setting to automatically clean up “abandoned host files” (RRDs and HW/SW Inventories as per the options’ inline help) is 30 days. This parameter can be modified in the “Global Settings” under “Site Management” → " Automatic disk space cleanup"

HTH,
Thomas

EDIT Please let me add that this option exists on both versions 1.6 or 2.0
