Generate config file for Junos 12.3

[Oucema Bellagha]

Host operating system: output of uname -a

16.04.1-Ubuntu SMP

snmp_exporter version: output of snmp_exporter -version

snmp_exporter, version 0.8.0

What device/snmpwalk OID are you using?

SNMPv2-MIB::sysDescr.0 = STRING: Juniper Networks, Inc. ex2200-24t-4g Ethernet Switch, kernel JUNOS 12.3R9.4, Build date: 2015-02-12 11:18:43 UTC Copyright (c) 1996-2015 Juniper Networks, Inc.

If this is a new device, please link to the MIB(s).

https://www.juniper.net/techpubs/software/junos/junos123/juniper-mibs-12.3R12.4.tgz

So now I extracted the juniper-mibs-12.3R12.4.tgz to $HOME/.snmp/mib as described in README but then when I try ./generator generate the snmp.yml file doesn't contain any module or configuration of Juniper MIB - is there anything I missed or how can I get an snmp.yml file for my Junos device?

I think there are a couple things going on here.

#1 - The timeout makes me think you have an SNMP community problem.  The default snmp.yml config the exporter ships with for `if_mib` is "public".  If you have a different community string you will need to add this to the generator and run it.

#2 - What changes to the generator.yml have you made?  It doesn't seem like you need any, and you don't need the juniper MIBs if you are just going to use `if_mib`.

Are there any specific sections of the Juniper MIB that you care about?  The generator does not look throught the MIBs directory and generate everything, it takes a specific set of walks configured in the generator.yml and then uses the MIBs to generate the metrics available via those walks.

Hey there,

So I do have a  community public in my switch config:

client-list list0 {
    x.x.x.x/24;
}
community grandstream11 {
    authorization read-only;
}
community public {
    authorization read-only;
    client-list-name list0;
}

for the generator.yml I have following config:

modules:
  # Default IF-MIB interfaces table with ifIndex.
  if_mib:
    walk: [sysUpTime, interfaces, ifXTable]
  # Interfaces if ifAlias is unique.
  if_mib_ifalias:
    walk: [sysUpTime, interfaces, ifXTable]
    lookups:
      - old_index: ifIndex
        new_index: ifAlias
  # Interfaces if ifDescr is unique.
  if_mib_ifdescr:
    walk: [sysUpTime, interfaces, ifXTable]
    lookups:
      - old_index: ifIndex
        new_index: ifDescr
  # Interfaces if ifName is unique.
  if_mib_ifname:
    walk: [sysUpTime, interfaces, ifXTable]
    lookups:
      - old_index: ifIndex
        # Use OID to avoid conflict with Netscaler NS-ROOT-MIB.
        new_index: 1.3.6.1.2.1.31.1.1.1.1 # ifName

and for monitoring I just need to monitor basic metrics: cpu, ram, Interface(up/down) and network Speed now the MIB of Junos contains a lot of information but I'm not really sure how to get even these basic metrics and the command:

snmpwalk -v 2c -c public x.x.x.x SNMPv2-MIB::sysDescr.0
SNMPv2-MIB::sysDescr.0 = STRING: Juniper Networks, Inc. ex2200-24t-4g Ethernet Switch, kernel JUNOS 12.3R9.4, Build date: 2015-02-12 11:18:43 UTC Copyright (c) 1996-2015 Juniper Networks, Inc.is

is giving output so something is wrong with my snmp.yml file generated obviously by the generator.yml above.

Up.

Hi,

I am also having difficulty with Prometheus and Juniper. Can you help me?
