Zabbix Server Cannot Keep up with Proxy Server

[rondeniable]

All,

I have a Zabbix Server in one datacenter and a Zabbix Proxy in another datacenter. Latency is low between datacenters.

With the Proxy i am monitoring about 50 hosts. The problem is that i am only getting partial data back to the Zabbix Server. Looking at graphs on the master of data i see large portions of data that is missing. However, at the same time i can see that the Proxy is in fact collecting the data, it is just not getting back to the master consistently.

Further, in the proxy_log occasionally i see the following errors.
Unable connect to the server [master-server.com]:10051 [Cannot connect to [master-server.com:10051] [Interrupted system call]]

The load on the master is fine. Never of 2, and database performance looks good. No slow queries or anything that seems delayed. Moreover, the agents that talk direct to the master never get behind.

It is almost as if the proxy cannot send the data fast enough. Is there a setting someplace that i can turn up?

Thanks in advanced.

Any solution?

I am facing the similar problem. Did you get any solution. The difference is that I get the error message all the time

Unable to connect to the server [xxx.xxx.xxx.xxx]:10051 [*** Cannot connect to [xxx.xxx.xxx.xxx]:10051 [Interrupted system call]]

Two things I have noticed.

1. If the servers are busy, that message is more frequently encountered.

2. Zabbix runs at a nice of 5 by default. If you do not renice it it will always take a back-seat to other processes. I renice mine to -1 to put it slightly ahead of the default 0 nice value, and therefore other processes. You could even renice it to -20 if you wanted.

What is your host architecture? x86? Sparc? Something else? I've also had messages like those much more frequently from Solaris boxes.
