Message Relay

How does monitoring on a message relay server works?

How do I know which clients are connected to a relay server and how to check the load?

Once a client got sophos installed it takes a while until I can see it in the SEC. How does debugging works? What can I check if the client does not show up in the SEC?

Regards,

Ingo

  • Hi,

    Without scraping router log files for specific strings, the only way to get overall visibility is in the database.

    The MessageSystemAddress field can be used to determine this information.  Typically a endpoint router has the address inthe format:

    Router$[ComputerName]:[token]

    e.g.

    Router$client1:34344

    If that same endpoint was messaging the server via a relay, called relay1. The RMS address of the client would be for exmaple:

    Router$relay1:43344.Router$client1:34344

    Note the . seperates the 2 router addresses.

    So with this info, from the database you can make queries for the number of computers which are "Managed", "Connected", "LastMessageTime", etc.. Which have a message system address that matches (contains), the relay you are monitoring for example.

    All the fields you need are in the "ComputersAndDeletedComputers" table in the "Core" database. http://www.sophos.com/en-us/support/knowledgebase/17323.aspx

    To debug a client, you just have to follow the messages from the client to the relay, from the relay to the management server and back down again.  /search?q= 13771 should also help
