Linux vmstat Recipe

1. Run vmstat in the background with a 1 second interval:

   nohup vmstat -tnw 1 > diag_vmstat_$(hostname)_$(date +%Y%m%d_%H%M%S).txt &

   1. Some older versions of Linux do not support the -t or -w flags.
2. Reproduce the problem.
3. To stop collection, kill the vmstat process. For example:

   pkill -TERM -f "vmstat -tnw"

4. Upload diag_vmstat_* and nohup.out

For background, see Linux vmstat.
