Hi Reka,
Can you please confirm, as you stated in the email below applicationId and
group alias cannot have the same string.
But that following example – see snippet of application.json - , with
“applicationId”, “application name” and “group name” the same but “group
alias” different should be working ok ?
Btw, I am not clear why we have this restriction, application and group should
be different objects, so why do “applicationId” and “group alias” have to be
different ?
Are we using a flat string search to identify objects ?
Thanks
Martin
Snippet of application json:
{
"alias": "s-n-gr-s-G12-t-a-2",
"applicationId": "s-n-gr-s-G12-t-a-2",
"components": {
"cartridges": [],
"groups": [
{

"groupMaxInstances": 1,
"groupMinInstances": 1,
"alias": "s-n-gr-s-G12-t-a-2-x0x",
"cartridges": [

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

Hi Martin,
I didn't encounter such issue, since i constructed a similar sample referring
your one, it worked fine for me. I will check with exactly your sample and
update how it goes.
Thanks,

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 Martin,
I'm looking into this issue..I have tried a similar sample as your one and got
the issue reproduced in the local setup. It seems to be a bug in our
application parser. Will work on further on this and update the thread..
Thanks,
Reka

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.axis2.rpc.receivers.RPCInOnlyMessageReceiver} - Cartridge c3 not
defined in cartridge group: [application] subscription-G1-G2-G3
[cartridge-group-name] subscription-G1-G2-G3 [cartridge-group-alias]
subscription-G1-G2-G3
java.lang.RuntimeException: Cartridge c3 not defined in cartridge group:
[application] subscription-G1-G2-G3 [cartridge-group-name]
subscription-G1-G2-G3 [cartridge-group-alias] subscription-G1-G2-G3
at
org.apache.stratos.autoscaler.applications.parser.DefaultApplicationParser.validateCartridgeGroupReference(DefaultApplicationParser.java:590)
at
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
Martin
