Hi Lucio,
Task is an internal mechanism to Wok and its plugins execute long time
processing. So that is not part of user knowledge.
Adding a log record as Task will make the user confused IMO.
So my proposal is: when the Task is started in the backend, add a log
record and set its status as 'pending'
Once the Task is completed (with success or not), change the log record
to success or failure according to what happened there.
To do that you will need to find a way to query a log entry in the JSON
file and edit/replace it to the updated entry.
What do you think about it?
Regards,
Aline Manera

User Request Log needs to be improved to track some special requests
of Kimchi, Ginger and Gingerbase which, when successful, generate an
asynchronous task to do the actual job. Examples are cloning vms,
upgrading software and creating volumes.
Currently those requests are always logged as successful, even when
the generated asynchronous task fails for some reason.
My proposal to solve this issue is to:
1 - Change the wording of all existing user log messages for requests
that generate asynchronous task.
i.e.: change "Clone vm 'name'" to "Start to clone vm
'name'"
2 - Log a couple of additional entries in AsyncTask for each task
executed:
- "Started Kimchi task ID 100: /plugins/kimchi/vms/name/clone" when
async task is started successfully
- "Successfully completed Kimchi task ID 100:
/plugins/kimchi/vms/name/clone" when async task works fine *or*
"Failure on Kimchi task ID 100: /plugins/kimchi/vms/name/clone
(KCHVM0001E failed to clone vm 'name')" when async task fails
3 - Backend/UI work to recognize the new type of entry:
{
"time": "11:49:55",
"date": "2016-08-12"
"zone": "BRT",
timezone continues the same
"req": "TASK",
use a specific "request" type for differentiation, i.e. TASK
"user": "",
"ip": "",
user and ip will be blank, since we are out of scope of the request
"status": 1002,
create 3 new status codes, say 1000 for "task started", 1001 for "task
completed successfully", 1002 for "task failed"
"app": "kimchi",
app will be informed by each plugin (backend change)
"msgCode": "WOKASYNC0002L",
async task log message Id, based on status
"detCode": "KCHVM00001E",
failed task details: original exception
}
>>>
{"target_uri": "/plugins/kimchi/vms/name/clone", "task_id":
100}
msgCode params
>>>
{"vm": "name"}
detCode params (optional)
>>>
Failure on Kimchi task ID 100: /plugins/kimchi/vms/name/clone
(KCHVM0001E failed to blah blah)
English log message
A corresponding log entry in text file for this example would be:
[2016-08-12 11:49:55 BRT] TASK 1002 kimchi Failure on Kimchi task
ID 100: /plugins/kimchi/vms/name/clone (KCHVM0001E failed to clone vm
'name')
With this implementation it will be possible for an admin to see:
* how much time a task took/is taking to run
* which other requests were done between task start and finish
Thanks,
