Verifikasi operasi¶

Verifikasi pengoperasian layanan Telemetry. Langkah-langkah ini hanya mencakup meter layanan Image untuk mengurangi kekacauan. Lingkungan dengan integrasi ceilometer untuk layanan tambahan mengandung banyak meter.

1. Dapatkan sumber mandat admin untuk mendapatkan akses ke command CLI ‘admin-only’:

   $ . admin-openrc
   

2. Lihatlah daftar meter tersedia:

   $ ceilometer meter-list
   +--------------+-------+-------+--------------------------------------+---------+------------+
   | Name         | Type  | Unit  | Resource ID                          | User ID | Project ID |
   +--------------+-------+-------+--------------------------------------+---------+------------+
   | image        | gauge | image | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   | image.size   | gauge | B     | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   +--------------+-------+-------+--------------------------------------+---------+------------+
   

3. Downloadlah image CirrOS dari layanan Image:

   $ IMAGE_ID=$(glance image-list | grep 'cirros' | awk '{ print $2 }')
   $ glance image-download $IMAGE_ID > /tmp/cirros.img
   

4. Lihat daftar meter yang tersedia lagi untuk memvalidasi deteksi download image:

   $ ceilometer meter-list
   +----------------+-------+-------+--------------------------------------+---------+------------+
   | Name           | Type  | Unit  | Resource ID                          | User ID | Project ID |
   +----------------+-------+-------+--------------------------------------+---------+------------+
   | image          | gauge | image | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   | image.download | delta | B     | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   | image.serve    | delta | B     | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   | image.size     | gauge | B     | acafc7c0-40aa-4026-9673-b879898e1fc2 | None    | cf12a15... |
   +----------------+-------+-------+--------------------------------------+---------+------------+
   

5. Ambillah ‘usage statistics’ dari meter image.download:

   $ ceilometer statistics -m image.download -p 60
   +--------+---------------------+---------------------+------------+------------+------------+------------+-------+----------+----------------------------+----------------------------+
   | Period | Period Start        | Period End          | Max        | Min        | Avg        | Sum        | Count | Duration | Duration Start             | Duration End               |
   +--------+---------------------+---------------------+------------+------------+------------+------------+-------+----------+----------------------------+----------------------------+
   | 60     | 2015-04-21T12:21:45 | 2015-04-21T12:22:45 | 13200896.0 | 13200896.0 | 13200896.0 | 13200896.0 | 1     | 0.0      | 2015-04-21T12:22:12.983000 | 2015-04-21T12:22:12.983000 |
   +--------+---------------------+---------------------+------------+------------+------------+------------+-------+----------+----------------------------+----------------------------+
   

6. Hapuslah file image download sebelumnya ``/tmp/cirros.img`:

   $ rm /tmp/cirros.img
