splunk network monitoring

Network traffic monitoring tools have a lot of, such as: MRTG, Cacti, Zabbix and so on, they have their own characteristics, different focus, only for different application scenarios for a variety of special needs. In addition to network traffic monitoring tools, there are nagios such a

Network devices are multi-port multiple monitoring projects, if one is added, it can be tiring. I started playing Zabbix is also a port to add a port, after a long time to add a switch. Suddenly think that there is a method of automatic monitoring and exchange, through a search of Baidu, found a lot of articles, according to the relevant article view, finally rea

The system supports remote user-side hierarchical query records. Each authorization rating user, you need to do this to authorize user name, password, allow to view the department's settings. In the above settings box, you can set the remote viewer's username, password, and the name of the group to view (that is, the department name, which corresponds to the group name set in the system). A grouped record that allows viewers of multiple different user names to log in to see them. The user na
