zabbix-module-sockets's Issues
Bad performance under load
Hello. We started to use zabbix-module-sockets-1.1.0-1.x86_64.rpm and hit following problem. When OS has a lot of sockets, /proc/net/tcp read becomes too slow. zabbix-agents use 100% cpu and become unreachable. Thus we get holes in all graphs from high loaded host instead of stats while we get load spike.
What do you think about some internal caching implementation of /proc/net/ files inside zabbix-module-sockets ?
I get errors with zabbix-3.4.4

module.h does not exist
Hello,
I want to test this module on my Zabbix server installed with apt on a Ubuntu machine (zabbix_server (Zabbix) 3.2.7).
I can see a *.rpm package for yum and a *.tar.gz archive on the code page. I have downloaded the tar.gz on Zabbix server and unpacked it. When running ./configure command i am getting configure: error: /etc/zabbix//include/module.h does not exist.
Please, let me know how do I handle this.

Support for 4.x version
Hi,
Please let us know if you have any plans to provide support for zabbix_server (Zabbix) 4.0.0rc3 version. Current import does not work for me :(
Thanks
