Private Cloud Monitoring

To maximize system uptime and performance, eLabNext uses Zabbix to continuously monitors the health and application uptime of Private Cloud installation.

In case of system unavailability or irregularities, our system engineers are automatically notified to solve the issue in order to avoid escalation. All events on the server are automatically logged.
