License block: Vezha features
What it shows
RAM free, MB in Vezha is displayed as mem.free_mib and shows how much RAM the node actually has in absolute terms.
Why it matters
In megabytes, it is easier to make practical decisions: whether there is enough resource for the next deployment, indexing or failover move. This is an operational metric for the here and now, when a quick operational conclusion is needed.
An example from practice
Before the queue was scheduled to restart, the team saw that the amount of free memory had fallen below an internal threshold. The restart was delayed for 20 minutes until the resource-intensive batch was completed.
