Failed to access to Agent null

[Former Member]

Hi, gurus

I´ve configured SolMan 7.0 Stack 16 with Diagnostics. Diagnostics worked fine, with Wily Introscope and SMD Agent.

Today, I´ve this error:

2009.03.12 18:22:59, Failed to access to Agent null. (detail: java.lang.NullPointerException)

when I go to the link Diagnostics Administrator --> Managed Systems --> Agent Administation

The log viewer say that:

error 2009-03-12 18:28:06:136 Failed to access to Agent null.

java.lang.NullPointerException...

Since you mentioned it was working fine earlier, there can be few possibilites for your issue

Agent is running or not in Satellite system.

Verify the connecting user SMD_ADMIN in Solman.

Run the self check in Diagnostics which will few more details requried
