Build snmp generator on Centos 7.

[Ollie]

Hey - this is my first dabble into Grafana + Prometheus + snmp-exporter, from what I can see this is a pretty awesome stack and I am really looking forward to seeing what I can do with it. I have Grafana + Prometheus + snmp-exporter installed and running using systemd - which in itself is pretty cool.

My aim is to monitor a bunch of Mellanox + Brocade + Arista switches.

I havent quite wrapped my head around the 'generator' - but at this time I am just trying to build it.

There is this, from here: 

sudo apt-get install build-essential libsnmp-dev # Debian-based distros
go get github.com/prometheus/snmp_exporter/generator
cd ${GOPATH-$HOME/go}/src/github.com/prometheus/snmp_exporter/generator
go build
make mibs

My question is in regard to build-essential + libsnmp-dev. What are the equivalent packages to install via yum on Centos 7?

Or more thoroughly how do I build the generator on Centos 7?

Thanks for any guidance you can provide !

Cheers.

Ollie

We're just in the process of adding those instructions to the docs.

Thanks very much Ben!

I'm getting this error when I try to install the following:

sudo yum install gcc gcc-g++ make net-snmp net-snmp-utils net-snmp-libs # RHEL-based distros

No package gcc-g++ available.

Would someone more educated, than me, point me in the right direction? Is it a dev-repo or something I need to add?

thank you!

You're right, that should be gcc-c++. Want to send a PR to fix it?

Hello All,

I am trying to install snmp-exporter in RHEL 7 and following the commands from the Github repo. 

sudo yum install gcc gcc-c++ make net-snmp net-snmp-utils net-snmp-libs net-snmp-devel --- done

 go get github.com/prometheus/snmp_exporter/generator -- latest error is below,

     # github.com/gosnmp/gosnmp

/root/go/src/github.com/gosnmp/gosnmp/gosnmp.go:351:72: unknown field 'Control' in struct literal of type net.Dialer

/root/go/src/github.com/gosnmp/gosnmp/v3_usm.go:159:9: undefined: strings.Builder

Initial error (package gopkg.in/yaml.v2: unrecognized import path "gopkg.in/yaml.v2" (parse) , I thought  "go get" was deprecated and as a workaround I tried 

wget https://storage.googleapis.com/golang/getgo/installer_linux 

chmod +x installer_linux 

source /root/.bash_profile

go install github.com/prometheus/snmp_exporter@latest -- 

can't load package: package github.com/prometheus/snmp_exporter@latest: cannot find package "github.com/prometheus/snmp_exporter@latest" in any of:
    /usr/lib/golang/src/github.com/prometheus/snmp_exporter@latest (from $GOROOT)
    /root/go/src/github.com/prometheus/snmp_exporter@latest (from $GOPATH)

Next steps:

cd ${GOPATH-$HOME/go}/src/github.com/prometheus/snmp_exporter/generator 

go build 

make mibs

I spent almost a week trying to figure out how to get this working, if someone could help me with all the steps for installing snmp-exporter for Prometheus in RHEL 7, I would greatly appreciate it.

What does "go version" show?  I am guessing you have a very old version if that "go install" command doesn't work.

However, there's no need at all for you to build snmp_exporter from source.  Just download the pre-built binary package from https://github.com/prometheus/snmp_exporter/releases

Probably the right one for you is

https://github.com/prometheus/snmp_exporter/releases/download/v0.20.0/snmp_exporter-0.20.0.linux-amd64.tar.gz

The thread you are replying to here is about building snmp generator, which is a different issue.
