Clientside performance problems when editing system lists

Jens Schröder — Tue, 02 Aug 2005 06:07:21 GMT

We have more than 1000 servers to be monitored by means of HP SIM and 5 admin groups that share the monitoring task. To increase the ease of finding one's servers, I created views for each admin group with up to 260 servers. Since the numbers vary, those server lists have to be maintained. Editing such a list causes a tremendous workload on the client (100% cpu time). In contrast the server stays cool, no problems visible there.
With smaller custom lists editing is feasible, but with the current set of servers the system nearly freezes, until the browser shows a timeout.
On my clients I've JRE Version 1.5.0 (Build 1.5.0_04-b05) and Version 1.5.0 (Build 1.5.0_02-b09) installed. On the server we run
Systems Insight Manager 4.2 with SP1 - Windows,
Build C.04.02.00.01 .
Has anybody experienced similar problems? Is this problem already known? Are there patches available, that fix the problem?
I'd be grateful for any hints ...

Try clearing the browser cache and the java plugin cache and then load the pages...This at times increases the performance for me. And also do you have any anti-virus running on the clients which is configured to scan the files for all the reads? This too can cause the stated performance problems. One more thing that i can think of is the version of JRE that you are using is not the one that is bundled with HPSIM. Not sure if that will cause any problems.

Hm, clearing the caches (IE 6 & JavaConsole) plus deactivating virusscanners etc. didn't help much. Still, every line representing a server takes approximately 3 secs to complete, after calling the edit mode. The java version included with HP SIM is 1.4.2_03, which is vulnerable to DoS attacks (http://sunsolve.sun.com/search/document.do?assetkey=1-26-57555-1&searchclause=%22category:security%22%20%22availability,%20security%22%20category:security).
Maybe this issue ought to be resolved in the HP SIM shipping version as well...

Hi Jens,

I do the same thing - create custom lists. I also have the same problem. It takes forever to display the list in order to edit it and it consumes 100% CPU just as you are seeing.

That being said - I have no solution to the problem, other than to run it on some other machine I am not actively using when I need to edit it.

I am hoping with SIM 5 they fix this problem (as well as allow alerting based on these custom views).

Thanks so far, guys!
Your nifty little plugin, David, seems to be able to solve my problem. It integrates almost seamlessly into HP SIM (main menu:tools:commandline tools:HP SIM), and the upcoming wizard allows for changing single server items.
However, I didn't manage to get it going.
Instead I ran into an SSH configuration error, of which you already warned in your article: "...Also note, the user that the SSH process is set to start up as must have the paths to the HP SIM runtime configured correctly for this to work as well...". The error message received is "EXCEPTION: Unable to contact the SSH server on node [myserver]". There's a OpenSSH service installed on the server, which is supposed to run under the local system account, but which won't start at all.
Am I digging in the right corner? Do you have a little more detailed information about getting your plugin running?

Can't get the tool runnig. I managed to install the CL plugin for HP SIM, but I'm still running into errors of the following kind:

EXCEPTION CLASS: com.hp.mx.dtf.sshClient.MxSshFailedConnectionException
EXCEPTION: Unable to contact the SSH server on node "erfsrzant2.bku.db.de".

What is meant by the sentence
"Also note, the user that the SSH process is set to start up as must have the paths to the HP SIM runtime configured correctly for this to work as well." ?

I already extended the system environment path variable by 3 entries (to HP SIM and OpenSSH directories), relaxed the group policies etc.
Since I have no insight into how SIM uses OpenSSH, analysis would take too much time.

Who can help?
