Server monitoring capabilities

[mitko_to]

We are looking for implementation of a Nagios as a monitoring system.
We have some monitoring requirements that are vital for us.
Can you please give us information does Nagios provides features like:

1.Monitoring CPU and process on a server in order to give us detailed statistic how many CPU % is used by each processor in real time or at least of 5 seconds period of time.
2.Does Nagios can perform Server network utilization based on the bandwidth of the NIC adapter and the packets that are tx/rx in real time.
3. Monitoring the network traffic per protocol in a real time.
4. Can all services performance be monitored on 1-to-5 seconds period of time on a server
5.Monitor memory usage based on processes on 1-5 second basis.

We need to have server monitoring which gives us detailed information which service/process consumes how many CPU,Memory, Network, disk I/O in same period of time , and that statistics to show the information for each 5 seconds or less.


Does someone know is Nagios able to provide these capabilities.

1. We generally poll in minutes, not seconds. Polling every second is going to cause a lot of load on the server.
2. and 3. I think https://www.nagios.com/products/nagios- ... -analyzer/ will work for you.
4 and 5. We generally poll in minutes, not seconds. Polling every second is going to cause a lot of load on the server.

As for 1, 4, 5, Nagios Log Server may be your best bet. That was you can log performance logs from the OS logs rather than having Nagios do its own checks.

Please let us know if you have any additional questions.
