About file rotation and timestamps

The log files created by a monitor’s file sink are automatically rotated when they reach a size of 10 MB. The 10MB file is saved as filename.csv.n where n is a number 1 - 10, and output is saved in a new file named filename.csv.n+1.

The .csv files are rotated up to 10 times.

In the following example, a monitor has exceeded 10MB of output. The initial 10MB are stored in filename.csv.1. Subsequent output is stored in filename.csv.

service@sms-cluster-1:/var/log/VPlex/cli> ll my-data.csv*
-rw-r--r-- 1 service users 2910722 2012-03-06 21:23 my-data.csv
-rw-r--r-- 1 service users 10566670 2012-03-06 21:10 my-data.csv.1


If the second file exceeds, 10MB:

• The previous filename.csv.1 is changed to filename.csv.2
• The filename.csv changes to filename.csv.1
• Subsequent output is stored in filename.csv

Up to 10 such rotations, and numbered .csv files are supported.

When the file sink is removed or the monitor is destroyed, output to the .csv file stops, and the current .csv file is is timestamped. For example:

service@sms-cluster-1:/var/log/VPlex/cli> ll my-data.csv*
-rw-r--r-- 1 service users 10566670 2012-03-06 21:23 my-data.csv.1
-rw-r--r-- 1 service users  5637498 2012-03-06 21:26 my-data.csv_20120306092614973
