Add this to cron to run every 5 minutes:

the following script uses previously generated RRDs, you'll get nice PNG pictures and index.html file with them:

# echo "*/5 * * * * root /path/to/script/vz_direct_traffic_log " >> \

  /etc/crontab && /etc/init.d/crontab restart

Add this to cron to run <code>vz_direct_traffic_log</code> every 5 minutes and <code>vz_direct_traffic_render</code> every 30 minutes:
 
  
−
  # cat << EOF >> /etc/crontab
+
  # echo "*/5 * * * * root /path/to/script/vz_direct_traffic_log " >> \
−
*/5 * * * * root /path/to/script/vz_direct_traffic_log

−
*/30 * * * * root /path/to/script/vz_direct_traffic_render
 
−
