In a detailed troubleshooting series for MySQL DBAs , the value is captured during a pt-stalk data collection event. It appears in the free column of the vmstat (virtual memory statistics) output, indicating that the server had approximately 122 MB of physical memory immediately available for allocation. Understanding the Log Context

For system administrators and developers, "122064" represents the importance of .

Used to identify memory exhaustion during database lock-ups.

: A "deep" analysis of system logs requires comparing this "free" value against a baseline. If the server normally has 8 GB free and suddenly hits 122 MB, you are looking at a memory leak or a massive query spike.

To provide a "deep" look, this post explores the technical context of this value within system monitoring, specifically as it relates to database performance and server health. The Significance of 122064 in System Monitoring

: In the specific trace where this number appears, it is analyzed alongside diskstats (disk I/O) and innodb transaction logs to see if memory pressure is causing threads to wait. Broader Context: Why Numbers Like This Matter

When a tool like pt-stalk or pt-sift captures this value, it isn't just a random number; it's a diagnostic snapshot used to identify "blockers" or resource contention.
