A set of zabbix UserParameter scripts and a monitoring template for linux systems.

This project ist originated on: https://github.com/scoopex/zabbix-agent-extensions

RPM and DEB distribution packages can be downloaded at: https://github.com/scoopex/zabbix-agent-extensions/releases

This package provides the following capabilities:

• linux standard monitoring using the standard items provided by the zabbix-agent
  • monitor memory behavior
  • monitor important servcies: smtp, ssh, cron
  • swap usage
  • 5min system load
  • monitor dmesg for bad behavior of the system
  • monitor the maximum and minimum of processes
  • automatic discovery
    • filesystems: inode and space measures
      (the amount of discovered devices can be limited by a configuration file on the monitored host)
    • network interfaces: packets and transferrates per second
    • storage devices: operations per second
  • number of processes
• monitor ICMP ping
• monitor the MTA mailqueue
• monitor NFS operations/retransmits
• apache monitoring: (enable /server-status available on localhost, https://httpd.apache.org/docs/2.4/mod/mod_status.html)
  • Check Apache Server-Status (Readers, Writers - alert if to many slots are in use)
  • Loadbalancer check
  • Monitor Mod JK backend status
• elasticsearch node and cluster monitoring (needs elasticsearch and es_stats_zabbix Python modules)
• redis Monitoring (needs redis Python module)
• NGINX Monitoring (enable /basic_status available on localhost, https://nginx.org/en/docs/http/ngx_http_stub_status_module.html)
• generic discovery (put json snippets to /var/run/zabbix-generic-discovery/ITEMNAME.json i.e. with puppet and get a combined discovery value)
• monitor puppet state
• linux software raid state
• check quality of ntp sync behavior
• check for required reboot
• Configurable autodiscovery of block devices
• Monitor performance havior of discovered block devices
• Configurable autodisovery of real disk devices
• Check smart state of disks and gather statistics
• Discover network devices and monitor performance and error behavior
• Zabbix agent version

Almost all measures are integrated in graphs which are displayed on the various host screens.
