I have been working as Linux/Unix administrator for 20+ years. Over the years, I have deployed numerous Zabbix installations each monitoring 100-500 physical and virtual hosts to aid me in maintenance and monitoring. Highlights: Zabbix - Deploy/upgrade Zabbix server/proxies and agents. Zabbix - Code scripts in Perl/Python/Shell to monitor your applications/services/log files better. Zabbix - Can modify default templates and add new items to monitor, suited to your environment. Zabbix - Troubleshoot current Zabbix items, triggers, scripts and templates. Zabbix - Troubleshoot and optimize your Zabbix installation. Grafana - Create new dashboards for you using data in your Zabbix. I have used Zabbix to monitor the following items (but not limited to): OS: Linux (Centos, Ubuntu/Debian) hosts, Windows hosts, Solaris Sparc/x86 hosts Server Hardware: HP iLO, Huawei iBMC, Dell iDRAC Network monitoring: Cisco Catalyst 9200 series switches, Enterasys C5G124 switches, Fortigate 900D Firewall, F5 BIG-IP I2000 series application firewall/load balancer Databases: MySQL, PostgreSQL, Oracle Other: VMware ESXi/vCenter 7.x, Elasticsearch Stack(ELK, Logstash, Kibana), Cyberark, RabbitMQ, Redis, Apache/nginx, coding custom Perl/Python/Shell scripts (to monitor log files, port banners, http/https request/responses), web service monitoring, etc.
