I can't get a distributed configuration to work

[Niels]

I've had a look at my logs. The problem is that I have to use the highest debug level to see anything of interest, but that also floods the logs with query statements.

On machine A, the main server, I see this:

 15702:20070607:113929 In main_nodesender()
 15702:20070607:113929 In send_to_master_and_slave(node:1)
 15702:20070607:113929 In send_to_master_and_slave(node:2)
 15702:20070607:113929 In send_config_data(nodeid:2,dest_node:2,maxlogid:100000000005318,type:1)
 15702:20070607:113929 In main_eventsender()
 15702:20070607:113929 In main_historysender()
 15702:20070607:113929 In main_eventsender()
 15702:20070607:113929 In main_historysender()
 15702:20070607:113939 In main_eventsender()
 15702:20070607:113939 In main_historysender()

Which appears to be the main server trying to send configuration to node 2, which is good.

On node 2 -- machine B -- I get nothing. I've tried all the clever grepping I could think of, and I see no indication that it ever receives anything from node 1. Which correlates with the fact that the database never changes, no matter what I do on the web interface.

It's still not working.

An item for machine C (no server, agent) never shows up in the items table on machine B (node 2). It has itemid 200000000000002 in the DB on machine A (node 1, web ui). The items table on machine B has itemids from 200000000010001 and up.

Yesterday we have discovered a nasty bug in inter-node communications which you guys are probably experiencing. It is related to processing of large data messages, messages largen than 2KB. No fix is available yet, we are working on it.

That is great news! I hope I'm affected!

Thanks!

Apparently no improvement with r4292

I know it's not nice to bump, but here goes...

I'd really appreciate help on this issue. Distribution is a major new feature of 1.4, and it's not working for me. Does anyone have it working? Can you please take a look at this thread?

[Alexei]

I'm working on a better documentation for DM. Patience, please

[Niels]

I'm _very_ patient
But I'm not so sure documentation is what I need. You've said that my configuration looks fine, and as far as I can see things are correctly installed and running here -- it just doesn't work.

Well, i have just setup a new setup, complete from scratch.

But still, the slave does not receive any data from his master.

I also tested it with a tcpsniffer, but my slave receives no packets from the master.

Should this already be fixed in the SVN?

[Alexei]

No, it is not in SVN yet.
