Opsview Agents installation

As a general rule, to avoid any backwards compatibility issues with older less secured technology, Opsview recommends that the version of the agents used is aligned with the version of Opsview Montior that you are running.

There are three basic approaches to monitoring devices on your network:

• The device sends details into Opsview Monitor when events happen or on a regular schedule. For more information, see SNMP Traps and Passive Checks.
• Opsview Monitor run checks to test network connectivity to the host and the services it provides. For more information, see Active Checks and SNMP Polling.
• Opsview Monitor talks to an agent installed on the device to see what is happening ‘on the inside’.

This document discusses how to achieve the last item in the list.

Linux Servers

We provide an agent package for all supported platforms for the Opsview Master within our repositories which will be installed automatically when you install any of Opsview Components.

For monitored hosts we also make agent packages available for other platforms through Opsview Download page. Installing this package will start a daemon that Opsview Monitor Collectors can use to interrogate the health of the system. It provides some default plugins (for checking on RAM, CPU and DISK, amongst others) that Host Templates within Opsview Monitor can make use of straight away.

You will need to ensure firewall access is open from relevant Collectors to port 5666.

You may also use any NRPE compatible agent and plugins, but you may need to configure both the agent and Opsview Monitor to make best use of it.

Installation

On Debian and Ubuntu:

sudo apt install /path/to/downloaded/opsview-agent*.deb

On RHEL, OL and CentOS:

sudo rpm -Uvh /path/to/downloaded/opsview-agent*.rpm

Note

The agent installation may fail on systems where SELinux is enabled; the agent should successfully install the second time it is attempted.
