I would like to specify the IP address that can be used to log in for each tenant https://support.abp.io/QA/Questions/6130/I-would-like-to-specify-the-IP-address-that-can-be-used-to-log-in-for-each-tenant

thx

Are there any plans to implement this kind of functionality in ABP Commercial?

I would like to specify the IP address that can be used to log in for each tenant. Is this possible with ABP Commercial's functions?

Thanks for providing solution. The performance was improved by increasing min threads.

On the other side, there are still requests that contain many redis command. I think 200~ commands in a request is irregular number, isn't it?

Thanks for sharing that. But increasing the timeout is not fundamental solution. The problem is slow commands. I doubt many redis commands dispatched at the same time affect to bad performance. One of the requests dispatched1456 redis commands. Is that normal?

Hi, we have redis commands that timeout. I asked that problem in StackExchange/StackExchange.Redis, and got the answer.

It looks like you're experiencing thread exhaustion (WORKER: (Busy=38,Free=32729,Min=8,Max=32767)), likely from long-running synchronous operations. I can't say about the rest of your application, but you for sure have some synchronous Redis calls (sync-ops: 7262, async-ops: 28127). You'll want to do all those things async to have much better utilization of the thread pool and less blocking/stalls as a result of thread exhaustion (waiting for a new one to become available).

According to the analysis, what we can do for solving timeout issue in ABP Framework?

By the way, we use "Amazon ElastiCache for Redis". When using AWS, is there a recommended redis service?

I would like to stop using redis to isolate the problem. How can I stop using redis?

Hi,

We found some redis commands are very slow(1~53s), and fails in test environment. We use amazon elasticache(redis) for our test environment.

slow command examples are below.

HMGET t:3a0c1d64-4d96-0ab6-9c31-0a332a2b8a8e,c:Volo.Abp.LanguageManagement.Texts,k:PortX:PortX_ja HMGET t:3a0c1d64-4d96-0ab6-9c31-0a332a2b8a8e,c:Volo.Abp.LanguageManagement.Texts,k:PortX:AbpValidation_en HMGET c:Volo.Saas.Tenants.Tenant,k:PortX:i:3a0c1d64-4d96-0ab6-9c31-0a332a2b8a8e,n:null EXPIRE t:3a0c1d64-4d96-0ab6-9c31-0a332a2b8a8e,c:Volo.Abp.LanguageManagement.Texts,k:PortX:AbpValidation_en EXPIRE t:3a0c1d64-4d96-0ab6-9c31-0a332a2b8a8e,c:Volo.Abp.LanguageManagement.Texts,k:PortX:AbpValidation_ja EXPIRE c:Volo.Saas.Tenants.Tenant,k:PortX:i:3a0c1d64-4d96-0ab6-9c31-0a332a2b8a8e,n:null HMGET t:3a0c1d64-4d96-0ab6-9c31-0a332a2b8a8e,c:Volo.Abp.PermissionManagement.PermissionGrant,k:PortX:pn:R,pk:admin,n:PortX.RegularProjectRequestHistories.Create

We had a lot of time to investigate the reason with Datadog APM and redis insight, but we've not found the exact reason.

[investigation result]

• the most portion of the commands are fast(12.81ms by 99 percentile). few commands are very slow(1~53s).
• server resource is enough (cpu/memory utilization is under 40%)
• redis resource is enough (cpu/memory utilization is under 40%)
• values returned by slow commands are not so large.
• we don't customize framework code which execute redis commands.
• we found the value of the key t:*:Volo.Abp.LanguageManagement.Texts,k:PortX:PortX_ja is almost empty: { "dictionary": {} }

With these slow commands, we couldn't meet our customers needs.

We doubt

• Amazon Elasticache(redis) have bad compatibility with ABP framework?
• We use Amazon Elasticache(redis) with default parameters. There is room for customization?
• Should we customize some configuration in ABP framework?
• We mis config some setting?

Thanks.

I have read the content you provided.

Now, I have question about deep implementation in abp application.

When I login in id application, there is no session info(image1). And after authentication redirecting to main application, there is session info(ex. access_token, id_token, ...) in local storage(image2).

My question is, how is the session info passed from id application to main application? Is there any global state?, or the services communicate with in back channel?
