LMS 4.2 runs very slowly

Unanswered Question

I installed Cisco Prime LMS using the small server (up to 500 devices) virtual appliance OVA.  It was set up with the standard settings for the OVA - 2 vCPUs, 4 Gb RAM, and 256Gb disk.  Web interface is very slow.  I have less than 200 devices.  What should I tune/check for to improve performance, hopefully without having to dedicate more compute resources?  Could this be an issue with my browser or version of java instead of the server?

I haven't used the appliance OVA but 4 GB of RAM seems quite low. If it were a Windows server, I would run double that.

The server seems to be running great - time for activities such as a User Tracking major acquisiton are quite short.

I did both simplify Java so that only 1.6.0_24 (the one that comes on the OVA) is on my machine and turned off the Windows firewall and performance has improved greatly.  It seems like Firefox is a bit more responsive than IE.  Has anyone else noticed this or have any additional tips?

Hi Mark,


TRY THIS :


1. For LMS getting started page:  Disable the launch of Getting Start page by default (as the first page after log in). Follow the below steps:

              a. Open the properties file name “gs.properties” under the path /<>/MDC/tomcat/webapps/cwlms/WEB-INF/classes/com/Cisco/nm/gs/ui

              b. Update the field IS_DEFAULT_PAGE as “false”

              c. Clear the browser cache and login-in(Daemon restart not required)


I hope this will help


Thanks

Afroj

Hi, We have the same behaviour.

The login page can be quickly access but once the credentials entered i can wait minutes before having any page displayed.

We have deployed Prime 4.2  Small licenses(less than 500 devices) and have less than 200 devices configured. The virtual server seems not overloaded.

How can we improved the navigation ?


Cheers

Hi,


we see the same issues with a very slow login page in LMS4.2. We upgraded our LMS test system from version 4.0.1 -> 4.2, the DCR was empty at this time. After entering the login credential we have to wait up to 10minutes before we can see the start page. After seeing the first page, the web performance is similar as before.


With version 4.0.1 this problem wasn't present.


We tried it with several ClientOS (WinPX and Win7) and different Browser version (IE8.0 and Firefox), the behaviour is always the same.

Hi,


same here with one of you customers on a OVA installation.

In my Windows 2008 lab installation I don't have this issue until today...


Are you using TACACS / Radius or local Authentication?

Looks like a TAC Case is necessary here...


keep us informed about any progress on your side

thnx

Hello,


we have installed LMS 4.2 some days ago. Now we have the same problem.


It's the OVA 1500 devices on Vmware Esx 4 with 8 GB of RAM. CPU and RAM usge is fine but you have to wait 10 minutes or more after logging in. No difference of using http or https.


Has anybody a solution for the problem or did anybody open a TAC case?



Regards,


Jan

Hi all,


I opened a TAC Case about the issue 5 days ago. The TAC engineer confirmed that he has several cases with this issue.


But unfortunately there isn't a solution yet. They tried to reinitialize the LMS databases and checked if there is an issues around local DNS resolving.  But all this wasn't helpful, the problem is still there. Currently the development is involved to analyze the logs we provided.

Has anyone experienced this issue with a Windows server or is this just a problem with the VMware OVA?

It seems we have the reason. It has something to do with the proxy settings.


As a workaround it's possible to remove the proxy, after that the login is ok  (at least in our case).


What we see also: the problem happens only for user with these default roles:

  • Network Admin
  • Super Admin
  • Full Authorization


Users with other roles never had the problem.

We have been tracking a problem internally where the Getting Started page hangs on login.  The problem is with changes to Cisco.com access.  We are actively working to get those fixed, but if this is what you're seeing the workaround is as follows:


a. Open the properties file name “gs.properties” under the path  NMSROOT/MDC/tomcat/webapps/cwlms/WEB-INF/classes/com/cisco/nm/gs/ui

b. Update the field IS_DEFAULT_PAGE as “false”

c. Clear the browser cache and login-in(Daemon restart not required)

We have had the same problem with our installation.  At first lms 4.2 responds great, but after changing some settings in the "getting started" menu, everything hangs.  I reverted to a clean snapshot install 5 times on tuesday, and the last time I did not do any changes in the "getting started" menu, and now lms works great.  We are running lms on a standalone server with esxi4.1 and OVA.


Is this workaround just for changing the default "getting started" page ?


We also seemed to experience problems when editing the backup settings and https settings under "getting started", but I cannot confirm this.

Anyone have an update on the LMS 4.2.x running slow? Have less than 100 devices on the network.

Running with performance tuning tool (PTT) enable and saw no change in performance, still slow.


I my case it is not a lack of system resources, memory and CPU at less then 30% usage.

LMS server: Solaris 10, sparc hardware with 32 CPU's and 32G memory.
