So, i've some questions:

do it's possible to scale the already running setup ?

1) Is it possible to make already running single server as a "master" where would RRD/MYSQL databases reside and that "master" server also would be as a one of the pollers.
And addition to that add two other pollers.

So in summary I just want to add two additional pollers to existing Observium poller, while all the device ID's and all the history would be kept.

Our DC is not big ~200 devices. We're considering this option to allow us to see what's going on when there problems in the network occur - when setup with single poller cannot reach the network node which is in other continent - all the data is lost. As I understand in distributed poller setup the poller which would reside in other continent would be able to 'grap' the monitoring data and (when the connection would be available again) it would send the information from other continent 'local' poller to the 'main; server. Do i'm correctly understand distributed poller principle ? Do the data saved in one (distant) poller could be resented when connection between two Pollers is up again ?

Thank you

It's already a feature. It's possible we might add some other infrastructure around it, but it works well enough for anyone who's capable of setting it up, I think.

thank you,
is it possible to know - if this job is in progress and would end up in some official - stable feature ?:)

I followed that guide for my deployment at the moment.  My single server installation (older server) couldn’t keep up with 800+ devices 45k+ ports.      

 

Things to keep in mind, alerts source from the individual poller, so each poller will need smtp access, I’m still not sure if custom alert checks are working on the individual poller though.  Which is kind of important, but other than that that guide is good.   I ran into an issue where a remote poller based on php 7.1 wouldn’t work with rrdcachced, but that was just recently fixed in r8956.    http://jira.observium.org/browse/OBS-2528.  Though I haven’t upgraded back to php7.1 to confirm, so my remote poller is still running php 7.0 at the moment.

 

Thanks,

Hi,

Some work has been done, but it's still very much "if it breaks you get to keep both halves". If you want to do some pioneering work, Marcus wrote up a blog post about it here: http://blog.best-practice.se/2017/10/scaling-observium-horizontally.html

Hello,

 

I would like to know if there any plans or solutions to make Observium run in distributed poller setup ?

 

Thanks
