Distributed polling is not working

[laf]

@abatapa

where i should specify this? On both and server and a poller? Or only at the server? Or only at the poller?

On my config it is specified on the server (as on manual for rrdcache) but it’s not on the poller (because it is not told there)

It needs to be set on all pollers in config.php

@abatapa

a) they DON’T use the same mysql server, because they both use their own librenms installation.

That’s not how this works, you HAVE to use the same MySQL, Memcached and rrdcached instances - you CANNOT have them separately.

@abatapa

it is completely not clear, that they should connect to THE SAME MYSQL SERVER? In my case, if it’s required mysql server on ubuntus1 is ready to get the connections from ubuntuhp (all permissions granted).

You’re more than welcome to edit the docs and improve them

@abatapa

So, do you mean, that on the poller (ubuntuhp) on the config file,

instead of: $config[‘db_host’] = ‘localhost’;

i should put:

$config[‘db_host’] = ‘192.168.100.23’; <- IP of the server (ubuntuS1, where memcached, mysql, rrdcache runs?)

Do i understand correctly?

Correct yes.

@abatapa

b) they are yousing the same memcached server (ubuntus1, 192.168.100.23) - its displayed on the config above.

regarding S1 missing distributed config - just to confirm, that on ubuntuS1 i should also put row

$config[‘distributed_poller’] = true;

to make it “distributed ready”?

You need to put all config for distributed polling, not just that. RRDCached, Memcached need to be set.

@abatapa

do i understand correctly? Or something else should be put?

(each row means something, each row can be the cause of it’s not working).

Sorry I’m not sure what you mean by that.
