| 1 | A simple shell program to log memory usage of a process. |
|---|
| 2 | |
|---|
| 3 | Usage: ./memlog.sh <cmd> [<params>] |
|---|
| 4 | |
|---|
| 5 | This will run the command '<cmd> [<params>]' and will log memory |
|---|
| 6 | usage once per second of the <cmd> process. The log will be written |
|---|
| 7 | to ./<cmd>.log and has the format: |
|---|
| 8 | |
|---|
| 9 | YYYYMMDD HH:MM:SS|<RSS> <VSIZE> |
|---|
| 10 | |
|---|
| 11 | where the RSS is the resident memory size in 1k blocks and VSIZE |
|---|
| 12 | is the size of memory used in the virtual address space (1K blocks). |
|---|
| 13 | |
|---|
| 14 | The accompanying test.py program is a small python program that |
|---|
| 15 | uses increasing memory and then frees the memory. You should see |
|---|
| 16 | the increase and decrease in the python.log file when you do: |
|---|
| 17 | |
|---|
| 18 | ./memlog.sh python test.py |
|---|
| 19 | |
|---|
| 20 | The test program runs for about 40 seconds. |
