While importance of intrusion detection from network traffic from an outside source is very important, there is also a need for network monitoring for companies within their private corporate networks. Network monitoring software can send alerts when the network goes down or becomes unavailable from hardware failure. The software can send alerts to key personnel administrators to their pager, email, or cell phone. Good network monitoring software continues to send status messages and traffic to efficiently keep track of any outages on the network. Network monitoring watches hardware such as router or network servers for responses. Depending on the software, it can send response requests every minute up to every hour. It can also detect outages in certain software such as web server or email applications. The software can send an HTTP request to monitor a web server, or it can send an SMTP message to an email server. If there is no reply from the respective software or server, the network monitoring software interprets it as an outage and promptly alerts a network administrator.
