There is no such thing as "better" here - else everybody would just be using that method.
The difference is simply that agent-based Nagios monitoring requires that you install software on the client, while agentless monitoring allows you to monitor the computer from afar using SNMP, WMI and the like. Because an agent runs on the computer itself, it can access quite a bit of data that may not be available remotely - but at the same time, the agent is more intrusive and requires more configuration. It is not unusual to use both methods at the same time, actually. Also, you have different security considerations for agentless vs. agent-based monitoring. Agentless monitoring requires that you enable SNMP, WMI, and/or other remote-access technologies. Agent-based monitoring requires that you put additional software (the agent) onto the monitored computer, and usually that software has to run as root or administrator or local system or a similar account with high permissions. Every time you add software to a computer, you also add potential exploits. chethan....@wipro.com wrote: > > > > Dear Experts, > > > > What are the differences and advantages b/w agentless nagios setup and > agent based (NRPE, NSCclient) Nagios monitoring. > > > > Please help me in understanding which is better to go with Agentless > or Agent based. > > > > Please Help. > > > > > > *Thanks & Regards,* > > > > *Chethan M N,* > Sr Engineer - EMS > -- Kevin Keane Owner The NetTech Find the Uncommon: Expert Solutions for a Network You Never Have to Think About Office: 866-642-7116 http://www.4nettech.com This e-mail and attachments, if any, may contain confidential and/or proprietary information.
