How to Check Server Performance in Linux Part 4

In part 4, we will be opening a few features that exist on nagios, because lots of people using the tools that this one, so there is no harm we try preview into this tool, so that we can know anything interesting in it, let's look alike.

The first time we can do is look at his Folder. From there we can see the shape of the local network we are monitoring. and be able to know which host is already UP (green) or DOWN (red). If the host is in a State of down can occur because at the time I monitor network on the host that are not connected by the internet or the host PC in the State shut down so that when dimonitoring, it at all does not produce any data. To view the details of a Host is UP, click twice (double click) on the host.

The host is one of the central objects in the monitoring logic. Nature – nature of the host are:
  • The host is usually the physical devices in a network such as routers, switches, printers, PCs, and so on.
  • The host has its own address as the IP Address or MAC Address.
  • The host has one or more services associated with it.
Services is also one of the central objects in the monitoring logic. Services associated with the host, because:
  • Services are attributes of the host (CPU load, disk usage, uptime, etc).
  • Services specified by the host, such as a DNS Record, etc.

There are various kinds of service – which can be used to host, but on the configuration I do, there are six services i.e. Current Load, Current Users, Disk Space, HTTP, SSH and Total Processes. This service is the sixth to be monitor by the hosts in a network.

We will see the contents of the detail of the features of the Services, to see more details by clicking a feature that is in Services.
a. Current Load

b. Current Users

c. Disk Space


e. SSH

f. Total Processes

Host Groups
Hostgroup is a group of one or more hosts. Hostgroup makes it easy for us to view the status details of hosts – hosts that are connected.

a. Summary
Summary on use of service view the status of each service that is dimonitoring on all hosts.

b. Grind
