Re: [Dev] How to do secondary indexing with bam-data-publisher for Stratos-Logging

[Srinath Perera]

Hi All,

Sorry for late reply

As I see it, secondary indexes are not a part of the agent API, which is
about collecting the data.

Secondary index is about analyzing / presenting the data. So if user
need secondary indexes, they will have to go to Cassandra directly, and
define them. I think we can do the same in logging impl.

 If we do it in the tenant creation time their will be around 10
 keyspaces per each tenant (given that for each server, we create a keyspace
 as I explained earlier) So even a user doesn't use a particular server
 their will be a keyspace for it. So if there are 1000 tenants there will be
 10 000 keyspace (even if some keyspaces are not used at all) So I think its
 better to create keyspaces when ever logs are publishing to that particular
 keyspace.

 Hi,

 Currently we are sending LogEvent data through bam data publisher
 to bam event receiver using a custom log4j appender. And we retrieve 
 logs
 using the hector API for the carbon log viewer. However, we need to 
 have
 secondary indexes for several columns so that we can filter log 
 information
 for a given column ( such as date, applicationName, priority,logger 
 etc)
 when creating the data publisher (keyspace). From the current Bam Data
 publisher implementation we cannot do secondary indexing all we can do 
 is
 define the column name and the data type of that column, and reciver
 creates the keyspaces for given columns with their data types.

So we don't have this requirement anymore, We are writing a separate log
tool kit for BAM so that users can download long running logs separately.

 There should be a clean way to do this. How did you decide to do it
 this way? Was there a discussion?

[Dev] Error when trying to view system log for a tenant

[Kishanthan Thangarajah]

I'm seeing $subject for a tenant in AS. Is this a known issue? The error
says I have to configure syslog. What are the changes i need to make in
syslog configuration?

Re: [Dev] Error when trying to view system log for a tenant

[Amani Soysa]

Yes this is a known issue. Right now we cant view tenant specific logs
without configuring syslog. However, I am writing a carbonMemory appender
to view tenant aware log events from the memory. So that users can view
most latest logs from the memory. However if you want to view  older logs
you need to configure logging either syslog, or BAM logging event receiver.

Re: [Dev] Storing duplicate data in AM DB and governance registry

If you go thru the DB schema you will notice how the API_ID is bring

Re: [Dev] Queries via UM datasource fails for one after the other

[Dimuthu Leelarathne]

Hi all,

This seems to be a blocker for us. Looks like a caching issue at mysql
and/or pooling layer.  I tried without the following indexing and still get
the same results. I don't think it is a mysql layer because the same SQL is
running on mysql_workbench.

CREATE UNIQUE INDEX INDEX_UM_TENANT_UM_DOMAIN_NAME
ON UM_TENANT (UM_DOMAIN_NAME);

thanks,

Re: [Dev] Queries via UM datasource fails for one after the other

[Sumedha Rubasinghe]

Dimuthu,
I was under the impression this was solved. Thought Anjana had a look @ it.
This cannot be a caching issue @ the database level. Then it should impact
everywhere. I still feel this is an application level concurrency issue.

Let me discuss with Anjana & get back to you. Sorry for allowing you to
live with this for long.

Re: [Dev] Queries via UM datasource fails for one after the other

[Dimuthu Leelarathne]

Hi Sumedha,

This is not an application level concurrency issue because how would you
explain,

1) With mysql_workbench while I have paused the program with a debug point.
2) There is concurrency associated with this scenario
3) The reverse works. When domain is given the ID is retrieved

My next steps,
1) Run using h2 server
2) Retrieve domain given the ID using same db connection

thanks,
dimuthu

Re: [Dev] Updated Invitation: Url Mapper Review @ Wed Jul 4 2:30pm - 3:30pm (am...@wso2.com)

[Amani Soysa]

Hi all,

Please find the meeting notes here.

In the URL Mapper UI {Mapping lists} making the mappings as links (show the
ports as well)
Test the security sample with virtual hosts.
Test accessing VH through SSL (test with IE and see)
To synchronize the deployment between nodes inside a cluster, use cluster
message when adding virtual hosts.
Test VH hosts with webapp lazy loading/unloading
Limit virtual hosts per web application.
Fix UI issues related to URL Mapping, add user friendly messages, tool tips.
Performance test for 10 000 virtual host, test server startup time memory
usage etc.
Do not deploy virtual host at server start up only add VH at the start up
deploy VH when tenants are loaded.
Put prefix (wso2.com) and no VH per webapp/services in configuration file.
Test address endpoints using SOAP UI, remove the hack done in
CompositeValve.

Regards,
Amani

Re: [Dev] Queries via UM datasource fails for one after the other

[Dimuthu Leelarathne]

Hi all,


This is a connection pooling issue. The reason for saying that is as
follows.
Here is the SQL = String sql = "SELECT UM_ID FROM UM_TENANT WHERE
UM_DOMAIN_NAME=?"

Consider the following control flow.

Control Flow
===

Connection dbConnection1 = getDBConnection();
Connection dbConnection2 = getDBConnection();
prepare and execute SQL using dbConnection2 -> result is successful
prepare and execute SQL using dbConnection1 -> result is unsuccessful
prepare and execute SQL using dbConnection2 -> result is successful
prepare and execute SQL using dbConnection1 -> result is unsuccessful

Now see we are executing the same SQL using same parameter using two db
connection. The dbConnection1 goes totally crazy for requests that hit the
above code segment - one after the other.

thanks,
dimuthu

[Dev] Remove tenant id/domain from tenantIdDomainMap / tenantDomainIdMap in JDBCTenantManager.

[Muhammed Shariq]

Hi folks,

To provide some background, currently in JDBCTenantManager we have two maps
namely tenantIdDomainMap and tenantDomainIdMap to act as a cache when
fetching a tenant's id via domain name or vise-versa. Whenever we try to
obtain the id via domain for example, it first checks if that particular
domain is present in the tenantDomainIdMap, and if only if its not
available it checks the DB.

We however never clear these tow maps, so if there is a domain-id mapping
it exist as long as the server is running. Note that we have these maps per
Stratos service, meaning AS, ESB, DSS etc maintains its own map
locally. Previously this was no issue since we didn't have the facility to
delete a tenant, but when trying to create the tenant deletion patch, I
came across some issues since we never clear this map.

For example say we have a tenant foo.com with TID - 10. If this tenant logs
into AS, the locals maps will contain the mapping tenant foo.com <=> TID -
10. Next we delete the tenant from Manager and also the delete the entry in
the locals maps of Manager, but still we have no way of clearing the domain
<=> ID mapping in AS (or any other service). So if we create another tenant
foo.com with TID-12 AS will still have the old domain-id mapping, which
obviously causes issue.

So I am looking for a way to clear these two maps. One suggestion was to
delete the domain-id mapping when unloading the tenant. For this we need to
add static getter methods for the two maps, not sure if that's a good idea,
or have a scheduled thread to cleanup the map periodically, or else have an
overloaded method, getTenantId(String tenantDomain, boolean readDB) ... ?!

Please suggest what would be the best way to clean up the local domain-id
mapping ...

Thanks,
Shariq.

Re: [Dev] Remove tenant id/domain from tenantIdDomainMap / tenantDomainIdMap in JDBCTenantManager.

[Afkham Azeez]

Tenant deletion is a very rare usecase. So, we need not complicate things
at this moment. Please note that deleted tenant IDs should not be reused.
So, my suggestion is, don't fix this.

BTW Why do we maintain 2 maps we can have single bidi-map. If i remember
correctly azeez fix this in some place.

One possible solutions is sending cluster message once you deleted the
entry. then it will update all the nodes within the cluster with
new tenant id domain map.  next we have to update other services as well.
for that we have to find a proper way(calling each and every
server and ask to update the map from db). cleaning up this map time to
time is not good idea since this map is heavily use by many components.

Re: [Dev] Remove tenant id/domain from tenantIdDomainMap / tenantDomainIdMap in JDBCTenantManager.

[Afkham Azeez]

As for the case of the map filling up, the key & value are very simple
string/int. Even millions of entries will result in very low memory
consumption. Millions of entries in this map translates to millions of
active tenants. There can be only one entry per tenant. So, once again, my
suggestion is this map cleaning up is not needed. The cost of doing this is
very high & the benefit is very very small.

Re: [Dev] Remove tenant id/domain from tenantIdDomainMap / tenantDomainIdMap in JDBCTenantManager.

[Afkham Azeez]

Yes, replacing the two maps with a bidimap were fixed about 1 year back.
This improved the efficiency since tenant id-> domain & domain -> tenant id
lookups were earlier resulting in two sets of DB calls. With the bidimap,
we were able to load the info using one set of calls.

We are not reusing the tenant id, actually if we try to create a tenant
with a deleted tenant domain then the new tenant id will be different, but
since we cannot update the individual maps in the separate services, we
still get the old tenant id for the newly created tenant. Of course, these
issue arises only if we delete a tenant and create a tenant with the same
domain, which is a rare usecase, so may be we can live with it.

Also as Sanjeewa mentioned, this map is heavily used by many components so
deleting records might cause a performance hit as well. Anyway I wanted to
bring this up before we freeze the kernel to discuss any possible solution

Re: [Dev] Queries via UM datasource fails for one after the other

[Anjana Fernando]

Hi Dimuthu,

As we talked earlier, did you do the step of querying the same record using
the UM_ID directly, rather than the domain name, using the same connection.
Also, try the scenario with H2. I actually cannot think of a reason how the
connection pooling can have any effect on this, because they are simply
database connections they keep, and the connection pooling layer does not
do any data caching. We should carefully try all the scenarios and see,
where the problem is actually is at. We will further work together tomorrow
to track down the problem.

Cheers,
Anjana.

 Hi all,

 This seems to be a blocker for us. Looks like a caching issue at mysql
 and/or pooling layer.  I tried without the following indexing and still get
 the same results. I don't think it is a mysql layer because the same SQL is
 running on mysql_workbench.

 CREATE UNIQUE INDEX INDEX_UM_TENANT_UM_DOMAIN_NAME
 ON UM_TENANT (UM_DOMAIN_NAME);

Re: [Dev] Infinispan caching with sync=false

[Senaka Fernando]

Hi Prabath,

The Infinispan Cache Manager that is available by default does not allow
you to configure many things. We have only made it possible to configure
the mandatory settings. Also, please note that the cache manager in Carbon
is pluggable and you also can extend/improve the existing cache manager to
support this kind of requirements.

Thanks,
Senaka.

Re: [Dev] Smoke test - Kernel Beta2 Packs

[Senaka Fernando]

Hi all,

I think that might be inconsistent. Packs from build 255 an P2 Repo from
build 143 might be incompatible isn't it?

Thanks,
Senaka.

Re: [Dev] Smoke test - Kernel Beta2 Packs

[Charitha Kankanamge]

Yes, unfortunately build 255 does not have p2 repo. That's why we were
repeatedly requesting a compatible repository to continue testing.
At least for next beta, please make sure to host a p2 repo.

Re: [Dev] Cannot log into product after creating Tennants

[Thilina Buddhika]

The previous error you got with the tenant admin seems to related to the
activation handler. Please check the product name in the carbon.xml with
the entry in the cloud-desc.xml.

The next error you have seen is due to a permission issue. Please make sure
that the role the 'test' user is assigned (everyone by default) has login
permission.

Thanks,
Thilina

Re: [Dev] Queries via UM datasource fails for one after the other

[Dimuthu Leelarathne]

Hi Anjana,

Few minutes ago I recreated the scenario. Then I reverted um.core to use
dbcp pooling and now it works perfectly.

I know ndatasource is fantastic! But looks like there are some issues with
it.

This would be a blocker for our kernel release. Can we use a newer version
of ndatasource?

thanks,
dimuthu

 Dimuthu,
 I was under the impression this was solved. Thought Anjana had a look @
 it.
 This cannot be a caching issue @ the database level. Then it should
 impact everywhere. I still feel this is an application level concurrency
 issue.

 Let me discuss with Anjana & get back to you. Sorry for allowing you to
 live with this for long.

[Dev] Include API-Manager features to P2-repo

[Evanthika Amarasiri]

Hi All,

While trying to verify the *API* feature of WSO2 Governance Registry,
realized that we need API-Manager features to be installed. The only
available P2 repo was [1] but in that, the API-Manager features were not
available. I have reported a JIRA at [2] to track this. We hope that these
feature will be available in the next p2-repo since API feature testing of
G-Reg is blocked due to this .

Re: [Dev] Remove tenant id/domain from tenantIdDomainMap / tenantDomainIdMap in JDBCTenantManager.

[Afkham Azeez]

One thing needs to be confirmed. In the rare case of a new tenant being
created with the ID of a deleted tenant, is there any security risk? I
mean, when we delete the old tenant, do we remove all deployment artifacts,
registry entries and so on? If not, there could be a security issue, where
the new tenant can see & download all the artifacts of the old tenant.

 Hi folks,

 To provide some background, currently in JDBCTenantManager we have two
 maps namely tenantIdDomainMap and tenantDomainIdMap to act as a cache when
 fetching a tenant's id via domain name or vise-versa. Whenever we try to
 obtain the id via domain for example, it first checks if that particular
 domain is present in the tenantDomainIdMap, and if only if its not
 available it checks the DB.

 We however never clear these tow maps, so if there is a domain-id
 mapping it exist as long as the server is running. Note that we have these
 maps per Stratos service, meaning AS, ESB, DSS etc maintains its own map
 locally. Previously this was no issue since we didn't have the facility to
 delete a tenant, but when trying to create the tenant deletion patch, I
 came across some issues since we never clear this map.

 For example say we have a tenant foo.com with TID - 10. If this tenant
 logs into AS, the locals maps will contain the mapping tenant foo.com<=> 
 TID - 10. Next we delete the tenant from Manager and also the delete
 the entry in the locals maps of Manager, but still we have no way of
 clearing the domain <=> ID mapping in AS (or any other service). So if we
 create another tenant foo.com with TID-12 AS will still have the old
 domain-id mapping, which obviously causes issue.

 So I am looking for a way to clear these two maps. One suggestion was
 to delete the domain-id mapping when unloading the tenant. For this we need
 to add static getter methods for the two maps, not sure if that's a good
 idea, or have a scheduled thread to cleanup the map periodically, or else
 have an overloaded method, getTenantId(String tenantDomain, boolean readDB)
 ... ?!

 Please suggest what would be the best way to clean up the local
 domain-id mapping ...

The log level for the logge, and the thresholds of the relevant appenders
need to be set to TRACE for this to work.

I see, there may also be a difference in configuration on how DBCP and
JDBC-Pool works. For example, in the registry/um.core data source, I've
added a validationQueryTimeout so it will not execute the validation query
all the time. We will check it out today. Newer version of ndatasource
means, it's basically using Tomcat JDBC-Pool, and I was checking the
changelog in JDBC-Pool for the latest release, and it does not mention any
issues fixed related to our problem. Also, did you get a chance to check
the scenarios I mentioned in my earlier mail? .. As a side note, we may
want to upgrade Tomcat to the latest v7.0.28 which was released Jun 25'th,
which seems to have several bug fixes.

Cheers,
Anjana.

 Hi Sumedha,

 This is not an application level concurrency issue because how would
 you explain,

 1) With mysql_workbench while I have paused the program with a debug
 point.
 2) There is concurrency associated with this scenario
 3) The reverse works. When domain is given the ID is retrieved

 My next steps,
 1) Run using h2 server
 2) Retrieve domain given the ID using same db connection

 thanks,
 dimuthu

 Hi all,

 I believe what is happening is AppFactory is trying to read the
 uncommitted data from the db. The attached screenshot explains the 
 scenario
 nicely. I kept adding test1,test2,test3  test8 and out of these 
 only
 even numbers are actually added - odd ones are failing.

 But after that I stopped the server did a "select *" before doing
 the "select UM_ID from where *"  in user.core. Then replaced the jar 
 and
 restarted the server. As you can see test9, test10, test11 and test12 
 are
 added without any issue at all. Meaning doing a "select *" somehow

We never reuse the tenantId.

And this was implemented to enable automated UI testing only in the branch.
IMO, I prefer to keep it like that until we fix the other high priority
items.

No, the tenant domain can get reused, and the maps will contain the old
tenant domain to old tenant ID mapping. So, things could fail when you try
to lookup the tenant ID by passing the tenant domain, if the tenant domain
was deleted, and then created with the same name.

 very high & the benefit is very very small.

Re: [Dev] CPU time measurement per tenant in Slive.

[Lasindu Vidana Pathiranage]

As shankar suggested ESB & BPS are the ones which caused problems with
their internal thread pools.
I tested both CPU time and Thread live time per request per tenant for
Application Server and Data Services Server inside the
CarbonStuckThreadDetectionValve. I created few web services, web apps
and data services to test them out. Worked well in measuring both CPU
& Live time for a request.

I was able to measure the CPU time of a BPEL process which consist of
a busy loop inside the process with the help of waruna. I captured the
CPU time inside ode/Scheduler-simple , call() method inside
SimpleScheduler class.

With the help of KasunI and IsuruU I was able to measure the CPU time
for ESB as well. I created a class mediator which consist of a busy
loop and was able to capture the CPU time for both in/out sequences.
ServerWorker handles the requests and ClientWorker handles the
responses. I was able to capture CPU time as well as Live time per
transaction for ESB as well. Both classes contain run() methods and
its where I was able to capture the CPU time. Since ESB uses
non-blocking threads, and nhttp, it seems only way to capture the CPU
time per thread is inside the run() methods.

Since I was able to measure the CPU time for AS, DSS, BPS, ESB for
almost all the cases, I tested out some Load tests for ESB. I sent
100,000 echo requests to AS via a proxy from ESB. The test statistics
revealed, it may take a considerable amount of time to capture the CPU
time for each request (overhead). Since ESB mostly concern on the
performance, it might cause some latency issues if I'm to include the
code inside it. I didn't find any alternative way to capture the CPU
time per tenant/thread inside ESB either.

Also if I'm to proceed with this I wanted to know how I can use this
statistics to publish to BAM2.
One alternative to use the same approach as it is used in bandwidth
measuring. It has used a TransportStatistics queue in tomcat to add
the statistics and usage agent in SLive retrieves them and publishes
to BAM. Even though I can add data captured inside the tomcat valve to
a queue in tomcat.ext/transport/statistics (CpuStatisticsContainer or
whatever) I'm not sure whether I can add data from ode (BPS) or
synapse (ESB) to the same queue in tomcat.

Lasindu

Please read carefully. I said tenantId is never resused :). I didn't say
domain is never reused.

 We are not reusing the tenant id, actually if we try to create a tenant
 with a deleted tenant domain then the new tenant id will be different, but
 since we cannot update the individual maps in the separate services, we
 still get the old tenant id for the newly created tenant. Of course, these
 issue arises only if we delete a tenant and create a tenant with the same
 domain, which is a rare usecase, so may be we can live with it.

 Also as Sanjeewa mentioned, this map is heavily used by many components
 so deleting records might cause a performance hit as well. Anyway I wanted
 to bring this up before we freeze the kernel to discuss any possible
 solution ...

Please try your test without the sys outs. AFAIR there were two sys outs
per one request. Please remove them and test.

I think you should be able to store them in the same way. But then we have
a problem. We cannot add these code/patches to synapse or ode. Can we?

[Dev] Have we tested JMX monitoring in trunk

[Amila Maha Arachchi]

Hi all,

$subject? I tried to follow some articles on how to remotely monitor WSO2
products via JMX (with 3.2.3 packs) and it seems the instructions mentioned
in those articles are not working. One such article is [1]. But there is a
workaround which can be found at [2].

Charitha et al, please pay attention to this during your testing cycles. If
this is broken, we'll have to fix this before we release the kernel.

If we lookup the tenant id by domain things will fail if the map is not
cleared, because it will try to fetch resources by the old tenant id from
DB (WHERE UM_TENANT_ID=${OLD_ID}), but we delete all records associated
with that TID. IIRC this was the failing case. Also there are some other
cases that needs to be addressed when deleting a tenant like deleting the
config registry resources entries (manager_config, esb_config etc ...)

Re: [Dev] Trace logs not working

[Amani Soysa]

To set trace level logs in global level,
Go to -> configure ->Global Log4J Configuration set the log level to trace.

If you want to enable TRACE_APPENDER send trace level logs to trace.log
file you need to add TRACE_APPENDER to root logger in log4j.properties
file. Or set it from the logging ui (Configure Log4J Appenders)

Re: [Dev] Trace logs not working

[Tharindu Mathew]

No, I went to Logging.

Searched for my package 'databridge' and changed the log level to TRACE.
This should work.

Azeez, if this does not work, then it's an issue. Following these steps
should just work.

In synapse we are using the nhttp transport and not dealing with tomcat, so
I think this is not possible with ESB.
Since we are dealing with the most sensitive part of synapse, this should
be done with extreme care.

I think we should look at how other matrices like latency is calculated in
synapse to get an idea.

Re: [Dev] Infinispan caching with sync=false

[Prabath Siriwardena]

Thanks Dimuthu, Thanks Senaka for your replies..

Also how about the letting the user provide the complete inifinispan cache
configuration file - may be pointed via our cache.xml and use that to
override all other settings and use it at the time of
creating CacheManager...

Thanks & regards,

Re: [Dev] Trace logs not working

[Amani Soysa]

Hi Tharidu,

Earlier I have not tested it properly. I put some trace logs in my
component and tested ..
if(log.isTraceEnabled()) {
log.trace("Just to see if tracing works");
}
And enabled the Logger to Trace in that particular class and it worked for
me.. Is this the same way you've done it?

Amani

Re: [Dev] Infinispan caching with sync=false

[Dimuthu Leelarathne]

Hi Prabath,

Yes. It is a great idea and (thinking aloud), in that case what we can do
is refer to inifinispan-config.xml from our cache-config.xml. If we
implement it like that then we will have maximum configurability. In order
to do that we can also need our CacheConfiguration to read any junk we put
in cache-config.xml and the CacheManager implementation would make sense of
it.

The only thing we will be sacrificing would be unified cache-config.xml
across different caching implementations. I think it is a small price to
pay compared to the above advantages we gain.

I am +1. But we need people to implement it. :(

thanks,
dimuthu

I had similar trace logs in my code as well. Let me double check again.

I assume you have not done any additional steps.
