License block: Vezha features
What it shows
FS free, MB in Vezha displays fs.free_mib for each mounting point. The agent filters service and virtual FSs to avoid noise in the state estimation.
Why it matters
Operationally, this is the easiest way to keep under control the space for logs, service data and temporary files. Absolute measurement in MB works well for “must act now” decisions.
An example from practice
On a node with a large log flow, the free space on the working mount began to decrease faster than normal. The rotation of the logs was increased until the critical threshold was reached.
