Ntopng fill the disk

[gsanchietti]

Ntopng is inefficient when managing the top_talkers database.

After months of work, it can easy fill the disk of machines with low space on the root partition.

Examples:

 2.2G Apr 30 12:11 /var/tmp/ntopng/0/top_talkers/top_talkers.db
 3.8G Apr  9 01:06 /var/tmp/ntopng/0/top_talkers/top_talkers.db

Proposed solution

Clean up the top_talker database once a week.

Test case
Check the bug is not repdoucible

I have some doubts on the QA @giacomo

[root@ns7loc14 ~]# ll /etc/cron.weekly/ntopng-cleanup
-rw-r--r-- 1 root root 171 May  8 10:09 /etc/cron.weekly/ntopng-cleanup

I thought that cron in hourly, daily, weekly should be executable file. At least I cannot test your bash file manually

Once the file /etc/cron.weekly/ntopng-cleanup is chmod a+x, the files are removed and the service is restarted

[root@ns7loc14 ~]# ll /var/tmp/ntopng/*/top_talkers/top_talkers.db
-rw-r--r-- 1 nobody nobody 0 May 14 17:16 /var/tmp/ntopng/0/top_talkers/top_talkers.db
-rw-r--r-- 1 nobody nobody 0 May 14 17:16 /var/tmp/ntopng/1/top_talkers/top_talkers.db
-rw-r--r-- 1 nobody nobody 0 May 14 17:16 /var/tmp/ntopng/2/top_talkers/top_talkers.db

Indeed, it's a bug. The fix is coming!
