To go the download page and select the distro of the host you want to monitor. In my case I’m selecting “Ubuntu Xenial AMD64” as it’s the closest thing to Ubuntu 18.04 listed.
If you plan on installing it on a remote server you’ll need to copy the link address.
Now on the remote server, use wget to download the agent.
root@xwiki:~# wget https://s3.amazonaws.com/opsview-agents/ubuntu16/opsview-agent_6.0.0.201807181203-1xenial1_amd64.deb
Its not particularly clear from their website how to install the package but I’ll try it apt first as it should install dependencies.

Nope! Lets try it with the dpkg tool.

Hmmm. Okay so lets try installing libgetopt-mixed-perl…
root@xwiki:~# apt install libgetopt-mixed-perl
And then…

After some playing about – I eventually realised the way to install the monitoring agent and have the dependencies automatically installed, is like so:
root@xwiki:~# apt install ./opsview-agent_6.0.0.201807181203-1xenial1_amd64.deb Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'opsview-agent' instead of './opsview-agent_6.0.0.201807181203-1xenial1_amd64.deb' The following additional packages will be installed: libgetopt-mixed-perl libtirpc1 rpcbind The following NEW packages will be installed: libgetopt-mixed-perl libtirpc1 opsview-agent rpcbind 0 upgraded, 4 newly installed, 0 to remove and 0 not upgraded.

The “./” preceding the package name is clearly quite important here but its not terribly well documented anywhere.
