Computer monitoring systems are used to gather data for the purpose of real-time incident notification, performance analysis, and system health verification. Without such a tool, a system administrator would have to login to each machine to collect information on a regular basis. This kind of repetitive task can be automated using a system monitoring tool. System monitoring can also help identify problems before they escalate to emergency status. This type of software is not only useful for network administrators. Home users with a small network or even just a single computer will benefit from advanced notification provided by system monitoring tools. Knowing that free space on the hard disk is running out, or that a particular server/daemon has gone down can be extremely useful.
Network ports With a Splunk Enterprise license, you can enable input on any TCP or UDP port. Splunk consumes any data sent on these ports. TCP is the protocol underlying Splunk's data distribution, which is the recommended method for sending data from any remote machine to your Splunk server. Important: In version 3.3.3 of Splunk, default syslog processing via UDP does not correctly handle line-breaks. To work around this issue, add _linebreaker = _linebreaker to the UDP stanza in $SPLUNK_HOME/etc/system/local/inputs.conf. This issue was resolved in 3.3.4.
If you have more than one server and you can't you afford outages during work hours (and maybe: work hours means from 0:00 - 23:59h each day), then you know the problem: You have to monitor your servers, the software|application and maybe some jobs on the
OpenIPMI is an effort to create a full-function IPMI system to allow full access to all IPMI information on a server and to abstract it to a level that will make it easy to use. See the SourceForge page for the source code.
What is Zenoss?
