 Description   

On certain environments with many slow devices it might help if more than 1000 pollers could be started.
For example we need to add an additional proxy only because existing proxy with 1000 pollers can only handle ~1000 NVPS. Above that pollers become 100% busy.
Problem is caused by slow devices, but being able to just start more Pollers could help in such scenario.

Please, please can we have more pollers? My Zabbix server is highly under-utilised as the max pollers is limited to 1000.

Hi,

I have medium size Zabbix installation with a few proxies. I have to collect a lot of data via SNMP from Ciscos. But the issues - I hve mostly slow (5 kBit/s) Satellite links to them.

Right now I use 1000 StratPollers and it just enough for now. But we are growing and it would be really nice to be able to inscrease it to 5000 or better to 10000. The server has plenty of resources to do this. Installind additionall proxy only because of this limit is inconvienient...

Thanks.

Adding my $0.02:  I ended up patching one of my proxies to allow > 1k pollers and it did in fact fix the problem I was having.

It's PR-5636 in the customer service desk titled "Max pollers on a proxy".  We have been running a patched 6.0 proxy like that for over a year with no issues.  I turned the value up to 2000 in my patch, but am actually running with this:

StartPollers=1500

It'd be really nice if you guys got this in before we upgrade to 7.0 - else we're going to have to by-hand patch again.

[edit added below]

The file to edit is src/zabbix_server/server.c in the source tree.

 

[second edit - added below]

The above is for the server - for the proxy modify proxy.c - looks the same.
