Monitoring

I implement and maintain monitoring for services, resources and security. Monitoring should not only show graphs – it should help detect incidents before customers notice them.

What can be monitored

• website and online store availability,
• CPU, RAM, disks, load and processes,
• nginx, PHP-FPM, MariaDB/MySQL, Redis and SSL certificates,
• backups, cron jobs, logs and unusual errors,
• security events, bans, suspicious logins and attacks.

I work with tools such as Zabbix, Nagios, Grafana, Site24x7, Wazuh, CrowdSec and system/application logs.
