Mk_ceph - I just do not understand how

I’ve been using mk_ceph with Proxmox without any issues prior to upgrading to 2.2—it hadn’t been working since the upgrade.

Running the plugin script directly didn’t give any output. When running the command manually, I’m getting an output.

ceph -n client.admin --keyring=/etc/pve/priv/ceph.client.admin.keyring -s -f json-pretty

Just found the solution and wanted to share:
There seems to be a problem with the variable $MK_CONFDIR, see

          # shellcheck disable=SC2034
          CMK_VERSION="2.3.0b1"
          
          
# Check Ceph storage
          # Config file must contain:
          # USER=client.admin
          # KEYRING=/etc/ceph/ceph.client.admin.keyring
          
          
# shellcheck disable=SC1091 # TODO: add a configuration example and remove this suppression
          # shellcheck source=agents/cfg_examples/ceph.cfg
          . "$MK_CONFDIR/ceph.cfg" 2>/dev/null
          
          
if [ -n "$USER" ] && [ -n "$KEYRING" ]; then
              CEPH_CMD="ceph -n $USER --keyring=$KEYRING"
              echo "<<<ceph_status>>>"
              $CEPH_CMD -s -f json-pretty
              if OUT="$($CEPH_CMD df detail --format json)"; then
                  echo "<<<ceph_df_json:sep(0)>>>"
                  $CEPH_CMD version --format json
                  echo "$OUT"
              else

I’ve changed that line to . "/etc/check_mk/ceph.cfg" 2>/dev/null and it works again. Maybe $MK_CONFDIR has been changed in v2.2?
