How do you check the availability of free space for Zabbix installation?

To check available free disk space before installing Zabbix, you can use standard system commands:

• On Linux/Unix systems — the df -h command shows free space on all mounted filesystems in a human-readable format.

Example:

df -h /var/lib/zabbix

This will display free space on the partition where the installation is planned.

• You can also use the du command to estimate the size of existing directories.

• Installation scripts often programmatically check free space, for example, using utilities or system function calls.

It is important to ensure that there is enough free space for the database, logs, and other Zabbix components, considering the minimum requirements.
