Performance advisor - status light red

A new DFM/OpsMgr installation.Everything works fine.

First attempt to use Performance Advisor ... we get no data.

Looking at Setup->hosts .. shows Login Credentials Good, but Status column show red.

Also, cannot see and filer logical and physical data at all. What does the red light mean?

OpsMgr Options->Performance Advisor and Perf advsor is enabled.

What could be wrong?

Re: Performance advisor - status light red

This is the only error we see in a dfm host diag output

XML (http port 80)     HTTP POST - Service unavailable

what dsoes that point to?

Re: Performance advisor - status light red

Hi,

It can be due to access restrictions that have been set up on the storage system with "trusted.hosts" or "httpd.admin.access" options.

These options restrict administrative access to a storage system, and cannot be overridden even if the DataFabric Manager server knows

the login/password of a storage system. Please verify following options on storage system.

[root@lnx181-93 ~]# /usr/bin/rsh -l root:*** ijaz options | grep httpd.admin
httpd.admin.access           legacy
httpd.admin.enable           on
httpd.admin.hostsequiv.enable on
httpd.admin.max_connections  512
httpd.admin.ssl.enable       off
httpd.admin.top-page.authentication on


[root@lnx181-93 ~]# /usr/bin/rsh -l root:*** ijaz options | grep trusted
trusted.hosts                *          (same value required in local+partner)

Re: Performance advisor - status light red

Could you please verify by setting host transport to   'dfm host set <host-name> perfAdvisorTransport=httpsOk'

Nagesh,

Thank you for responding.

Here are my httpd settings:

[root@vmware-opsmgr ~]# rsh netapp01 options | grep httpd
httpd.access                 legacy    
httpd.admin.access           legacy    
httpd.admin.enable           on        
httpd.admin.hostsequiv.enable off      
httpd.admin.max_connections  512       
httpd.admin.ssl.enable       on        
httpd.admin.top-page.authentication on       

[root@vmware-opsmgr ~]# rsh netapp01 options | grep trusted
trusted.hosts                *

I had the trusted.hosts originally set to my desktop machine's IP address but reset it back to defaults to see if that made a difference.

Nagesh,

Ok, I have to admit I'm confused now.  At the moment, perf monitor seems to be working.  I'm not exactly sure what change I made that made it work.  Here's a summary of what I changed, mainly based on your previous reply:

I changed trusted.hosts back to '*'.  I added the OpsMgr host to the NetApp's hosts.equiv file.  I also went back into the NetApp Management Console and went to the Hosts Setup page and reloaded the host with "HTTPS Ok" enabled and hosts.equiv disabled.  I found that if I told it to use hosts.equiv, it would fail the credential check and the XML error reported above would happen.  Didn't seem to matter if I added the OpsMgr host to the hosts.equiv file or not.

At the moment, it seems like it's working.  I'm going to have to learn a LOT more about this to get a better idea of why, though.
