Unable to Log-in to APIC-EM - after I enter the credentials get stuck loading

Hello, I installed the APIC-EM v1.2 on a VM.

I got up and running the ui, reverse proxy & router services from the grapevine console.

when I try to login to the APIC-EM I enter the credentials in the APIC-EM login page and get stuck loading but never change as shown below:

i follow the Tshoot steps in the post-installation tasks but I can find the issue.

Your help would be really appreciated!

Br,

Pls wait for the services to come up ( running state) . there are total of around 34 services. All services should come to running state.

You could monitor the service state from https://<apic-em>:14141

hope this helps

Re: Unable to Log-in to APIC-EM - after I enter the credentials get stuck loading

Could we check services status .

1. ssh to the APIC_EM Console OR https://<api-em>:14141

2. user name grapevine

3. grape intance status to check for all services running. All services should be in Running state

Thanks Rohan for the quick response. I Checked the grape instane status and the only running services are the router, reverse proxy and ui services:

from the web interface i can see the following:

should all the services be up and running? in the Troubleshoot info states that these three are the main services.

thanks!!

wait for all the services to change to running state.

there are services in harvested state . you need to wait for all services to be in running state

thanks Rohan! should I just wait for the services to come up and switch from Harvested to running state? or should I manually start them with the plus button from the Grapevine web interface?

thanks!

Re: Unable to Log-in to APIC-EM - after I enter the credentials get stuck loading

How can we troubleshoot why the services are not starting? I can leave the server running for a week and I still have services in the harvested mode. If I load a page that has that service not running, I get a small window stating "Page temporarily unavailable. Waiting for xxx-service to come up' I can sit here for hours and the services do not come up. so far I've resorted to manually 'growing' instances in the admin overview page.

Re: Unable to Log-in to APIC-EM - after I enter the credentials get stuck loading

I have the same problem. Even after a clean install once I reboot the servers (3 servers) only some of the services change to green, all the others stuck in starting or in unresponsive. Did the powering down/up procedure from the deployment guide but I still get the same result.

APIC-EM version 1.3.1.9

Please help.

More likely than not, this might be because of the disk throughput of your host on which APIC-EM ISO/OVA is deployed.

Can you please make sure your host is compliant with following specs?

CPU (cores)Minimum Required: 6, Recommend: 12
CPU (speed)2.4 GHz
Memory64 GB [ For a multi-host hardware deployment (2 or 3 hosts) only 32GB of RAM is required for each host. ]
Disk Capacity500 GB of available/usable storage after hardware RAID
RAID LevelHardware-based RAID at RAID Level 10
Disk I/O Speed200 MBps

Re: Unable to Log-in to APIC-EM - after I enter the credentials get stuck loading

Thank you for the fast response.

In my case all the 3 servers have this specifications:

CPU (cores): 12

Memory: 64GB

Disk Capacity: 500GB

Regarding disk I/O, I can't verify the speed but in the installation it does not raise an error when testing the disk throughput. Is there a way to check the performance via VMware Vcenter? I can see also latency values to the disk, what should be a good value?

If you SSH into the APIC-EM shell and run check_diskio command, you should get the output. E.g.

$ check_diskio

Running disk check (count=512), please wait...

512+0 records in

512+0 records out

536870912 bytes (537 MB) copied, 2.05017 s, 262 MB/s

Cleaning temp files...

Disk check complete

Re: Unable to Log-in to APIC-EM - after I enter the credentials get stuck loading

My install is a VM. Previously, our sysadmin had given me 16GB of RAM, as 64 is a huge number for an application like this. With 16GB available, the system only utilized a maximum of 10gb. I've had the admin bump the RAM, now up to 24 but the system is only reserving 18Gb. I am still seeing services that are in the harvested state. Right now VMWare shows 18Gb used, while FREE is reporting only 2.9Gb in use from the OS. I am currently unable to log into the system.

It's also worth mentioning that I've only got 4 procs right now, but my utilization shows at 1.8GHz...and there shouldn't be a need for any more since I'm not spiking what I have. Typically our organization will only provide more resources if the system shows it needs them. My resources were provided according to this school of thought.

Are there any specific errors I should be looking for in the logs? I'm unfamiliar with troubleshooting a container environment.
