License block: Vezha features
What it shows
DISK write, kbps in Vezha corresponds to the metric disk.write_kib_s and is calculated from the delta of system disk counters on Linux.
Why it matters
Writing often becomes the first cause of latency under load: logs, queues, flush in the DB. Early detection of the growth of the write flow allows you to intervene before the degradation of the service.
An example from practice
After changing the logging level, the recording volume jumped several times. The team quickly reduced the verbosity of the logs and returned the normal I/O profile.
