The data collector processes perform network discovery, SNMP polling, process flow records and record the traffic history. The data collector process is running if the Start button is disabled (and the Stop button is enabled).
Click on the Stop button, then click on the Yes button to confirm that you want to stop data collection. Wait approximately 20 seconds before clicking on the Start button to restart data collection.
Normally you should leave the data collection processes running. Stopping data collection will result in the loss of data. However, there are some configuration settings that require that the data collection processes are restarted before they take effect (see File>Configure).
The web server process refers to the process serving web pages associated with Traffic Sentinel. If the web server process is not running you will not be able to access Traffic Sentinel through a web browser. You will need to log in to the server and manually start the Traffic Sentinel processes using the command:
If this does not work you might also need to make sure that httpd is also
running using the command:
/sbin/service inmsfd restart
/sbin/service httpd restart
Click one the Restart button to restart the web server process. Restarting the web server will not result in data loss.
Normally web server restarts are not required. However, there are some configuration settings that require a web server restart before they take effect (see File>Configure).
The discovery process runs periodically to discover new network devices specified in Agent Range sections in the configuration (see File>Configure).
The discovery process will run periodically and pick up new configuration settings. You might want to run discovery manually if you have just added a new Agent Range to the configuration and want to ensure that new devices are promptly discovered (see File>Configure). Click on the Scan for Agents button to trigger a new discovery sweep.
