Solved FreeBSD11 nagios4 pkg doesn't install check_snmp

[Matthew Davidson]

Hello -

I've installed a fresh FreeBSD11 and then nagios4 using pkg but it doesn't install the check_snmp plugin.


I've tried installing the following additional packages using pkg
nagios-snmp-plugins
nagios-snmp-plugins-extras

But still no check_snmp plugin under /usr/local/libexec/nagios

I read somewhere you need net-snmp installed before installing nagios4 so I started from scratch and installed net-snmp first then nagios4 but no joy.

Doesn't anyone have any suggestions on what to try now.

Cheers
Matt

Did you try the net-mgmt/nagios-check_netsnmp port?

I think it installs check_netsnmp though, not check_snmp, so you'll need to make the relevant change in the Nagios config to do that.

Sorry I don't have a Nagios instance I can check this against...

Check the files that are installed with net-mgmt/nagios-snmp-plugins: https://svnweb.freebsd.org/ports/he...plugins/pkg-plist?revision=411020&view=markup

Note the files:

libexec/nagios/check_snmp_disk
libexec/nagios/check_snmp_load
libexec/nagios/check_snmp_proc
libexec/nagios/check_snmp_swap

I read somewhere you need net-snmp installed before installing nagios4 so I started from scratch and installed net-snmp first then nagios4 but no joy.

If something is required by a port it will automatically be installed.

Thanks for your replies.

Yes I have tried installing the following using pkg
snmp4nagios
nagios-snmp-plugins
nagios-snmp-plugins-extras
nagios-check_netsnmp

Still no check_snmp

By all accounts it seems check_snmp is part of nagios-plugins which installs automatically when I install nagios4

If I look in the pkg-plist check_snmp is listed but it has %%NETSNMP%% prepended
https://svnweb.freebsd.org/ports/head/net-mgmt/nagios-plugins/pkg-plist?revision=376834&view=markup

Does anyone know the significance of the %%NETSNMP%% prepend? Is it saying I need to set a variable NETSNMP to something before I run pkg install [package]?

To answer your question, it corresponds to checking the box when choosing options for "SNMP support (check_snmp)".

However as you installed a package, you don't get to choose those options and by default SNMP is off. You'll need to install from ports, so you can choose the options you want.

Thanks! Installing from ports was the pathway to success.
