Hi Reka,

Thanks for looking into it,

Yes, the behavior is not consistent, I also experienced a successful run here 
and there (as pointed out somewhere in the email thread). Please note that the 
issue always seems to come up in my setup if the application is the first one 
to be deployed after stratos is started up. The following sequence demonstrates 
the experienced behavior


1.      Start up stratos

2.      Deploy application -> typically fails, (not all instances start up)

3.      Remove application

4.      Re-deploy application -> always seems to succeed, all instances start up


Btw, did you take a look at the (email thread, JIRA)  attached logs, including 
the debug log – they demonstrate the sequence described.

As a side note this is currently blocking me from testing some other test / use 
cases we have

Thanks

Martin

Hi Martin,
I could reproduce an issue where C2 was not coming up. But after one/two 
minutes, even C2 has also come up and became active. So, application got 
activated finally. Now I'm not even reproducing any thing like. All the way 
application is becoming active without any issue. I will try with few more time 
to reproduce this..I will also check whether any concurrency issue is there..
FYI: I used the artifacts that you have provided.
Thanks,
Reka

Forgot to mention, please note that the alias name and group name don’t match 
the ones I provided with the artifacts (which was modeled as Reka suggested) – 
anyway, the result (failure of one cartridge instance not being started up) is 
the same.

Thanks

Martin,
Access the UI from [1], and find the relevant topology view for the application.

HI Martin,
Would you be able to share the Application Topology structure from the UI? That 
would also help to narrow down the issue.
Thanks,
Reka

Hi Reka,

I tried what you suggested - but only with limited success - changing the 
application name and alias to make it different from the top level (or parent) 
group name, alias (see snippet below). For the full json please see the 
attached application / cartridge-group.json.
I had an one time success using the proposed naming pattern but subsequent runs 
failed again to bring up all 4 cartridge instances (which seems to suggest to 
me a potential race condition).

What is also interesting is that after un-deploying the application and 
re-deploying all  4 cartridge instances come up – see debug log enabled log 
file wso2carbon-debug-2nd-subscription.log.

I attached the wso2carbon.log from a failed run without debug enabled and one 
with debug enabled.

Thanks

Martin

Hi Martin,
Found the issue. It was an issue with your application definition. You were 
using same Id for applicationId and the blower group alias. So in this specific 
case GroupMonitor and ApplicationMonitor got messed up with this configuration. 
Please note that it would be better to use GroupName also a unique value as to 
avoid confusion in case if the same group used by multiple application. Please 
see the configuration below as your one:

{
    "alias": "subscription-G1-G2-G3",
    "applicationId": "subscription-G1-G2-G3",
    "components": {
        "cartridges": [],
        "groups": [
            {
                "name": "subscription-G1-G2-G3",
                "groupMaxInstances": 1,
                "groupMinInstances": 1,
                "alias": "subscription-G1-G2-G3",
                "cartridges": [],
                "groups": [
After i changed it to below configuration, your sample worked fine as attached 
the UI Topology.

{
    "alias": "subscription-G1-G2-G3-G4",
    "applicationId": "subscription-G1-G2-G3-G4",
    "components": {
        "cartridges": [],
        "groups": [
            {
                "name": "subscription-G1-G2-G3",
                "groupMaxInstances": 1,
                "groupMinInstances": 1,
                "alias": "subscription-G1-G2-G3",
                "cartridges": [],
                "groups": [
Hope this will help you. Will check further whether we need to do the 
validation. Then we can find such issues in the application addition itself.
Thanks,
Reka

I didn't encounter such issue, since i constructed a similar sample referring

Hi Reka,

I verified the fix and it is working, however while testing the scenario I 
noticed a different issue:

When the application is subscribed the very first time after starting up 
stratos, only 3 of the 4 cartridge actually spawn an instance (which all become 
active). However, If I subsequently remove the application (without restarting 
stratos) and re-subscribe again all 4 cartridges spin up an instance.

I attached the log file which has both scenarios (1st subscription of the app 
and 2nd one) plus the cartridge groups and application json.

WDYT, is it a configuration error or a possible bug ?

Thanks

Martin

Hi,

I think I am seeing an issue with nested grouping:

When I define a parent group (no cartridges) and 2 nested children groups, each 
containing cartridges with a different types I see an exception that a 
cartridge group is not defined in the parent  group :

TID: [0] [STRATOS] [2015-04-22 20:46:58,495] ERROR

org.apache.stratos.autoscaler.applications.parser.DefaultApplicationParser.parseGroups(DefaultApplicationParser.java:569)

If I define the same cartridge types in both children groups the application 
deploys fine (e.g. replace cartridge type c3 / c4 with c1 / c2 in group 
“multiple-groups-no-startup-G2”, see …”working”…. Artifacts)

I attached wso2carbon.log / cartridge-group.json and application.json files and 
all the other artifacts  to the email.

Also attached the artifacts (cartridge-group / application) and wso2carbon log 
for the working case (see …“working”… ) for comparison

I created a JIRA for this issue: 
https://issues.apache.org/jira/browse/STRATOS-1339

Thanks
