Performance monitoring

[deepavaidya]

Hi

Please can you tell me what are performance parameters monitored by nagios XI.

Does it include all of these (memory used, interface availability, network traffic,CPU utilization, network availability, disk space, error rate, packet loss, etc.) ?

If I have added a host using monitoring wizard and added many services to it and later want to add a disk usage service or a memory usage service....how do I do it ? Do I need to delete the host and discover it again from monitoring wizard and check the disk usage or is there any other way to add it without disturbing the existing set up ?

Nagios will monitor basically anything you throw at it. Nagios gets the parameters such as memory and CPU from plugins, which report this as performance data. This is what is used to make graphs. It depends on the plugin, but many of them will offer this sort of data,

You can enter into the Core Config Manager and make them on a case-by-case basis. If you only need to change the check and nothing else like check frequency, notifications, etc., then you can simply clone one service and make the edits on the new service.
