Viptela SD-WAN - CPU & RAM missing

[Cameron76]

Hello,

I would like to ask you for your help with Viptela (Cisco) SD-WAN devices. The system resource graph of CPU and RAM does not work for these devices.

Memory usage graph:

Processor usage graph:

Cisco Viptela basic support

I tried to delete rrd files for both CPU (poller-perf-processors.rrd) and RAM (poller-perf-mempools.rrd) to create new ones, but doesn’t help.

All other things (e.g. interface utilization) seems to working correctly.

Thank you for your hints.

Hi,

is this enough? Is there anything else to add for troubleshooting?

https://mibbrowser.online/mibdb_search.php?mib=VIPTELA-OPER-SYSTEM

CPU:
INFRA [root@librenms-test ~]# snmpwalk -v 3 -l authPriv -u <snmpv3_user> -a SHA1 -x AES -A <auth_password> -X <priv_password> 10.128.78.231 1.3.6.1.4.1.41916.11.1.10
SNMPv2-SMI::enterprises.41916.11.1.10.0 = STRING: “0.56”

RAM:
INFRA [root@librenms-test ~]# snmpwalk -v 3 -l authPriv -u <snmpv3_user> -a SHA1 -x AES -A <auth_password> -X <priv_password> 10.128.78.231 1.3.6.1.4.1.41916.11.1.18
SNMPv2-SMI::enterprises.41916.11.1.18.0 = STRING: “3412832”

Thanks for your info.

Hello guys,

Please nobody know?

INFRA [root@librenms-test ~]# cat /opt/librenms/includes/definitions/discovery/viptela.yaml
modules:
os:
serial: .1.3.6.1.4.1.41916.3.1.1.1.5.1.0
version: .1.3.6.1.4.1.41916.11.1.2.0
hardware: .1.3.6.1.4.1.41916.11.1.47.0

INFRA [root@librenms-test ~]# cat /opt/librenms/includes/definitions/viptela.yaml
os: viptela
group: cisco
text: ‘Viptela’
type: network
icon: cisco
over:
- { graph: device_bits, text: ‘Device Traffic’ }
- { graph: device_processor, text: ‘Processor Usage’ }
- { graph: device_mempool, text: ‘Memory Usage’ }
mib_dir: cisco
discovery:
-
sysObjectID:
- .1.3.6.1.4.1.41916.

Isn’t there a problem? Missing OIDs…

Found also this one (just for memory):

Thanks a lot for your help.

This is community led and people help when they can or when they know.

[Cameron76]

Is there any general procedure or steps (regardless of the Viptela vendor) that I should take to fix the problem and find out the reason why it’s not working?

Is there any documentation for this deeper troubleshooting?

I am proceeding in general, I have discovered an issue, so is there a project leader I can consult with?

Thank you, @laf .

/opt/librenms/includes/definitions/discovery/viptela.yaml:

    os:
       	serial: .1.3.6.1.4.1.41916.3.1.1.1.5.1.0
        version: .1.3.6.1.4.1.41916.11.1.2.0
        hardware: .1.3.6.1.4.1.41916.11.1.47.0

    processors:
        data:
            -
             	oid: systemStatusCpuIdle
                num_oid: .1.3.6.1.4.1.41916.11.1.16.0

    mempools:
	data:
            -
             	total: .1.3.6.1.4.1.41916.11.1.17.0
                used: .1.3.6.1.4.1.41916.11.1.18.0
                free: .1.3.6.1.4.1.41916.11.1.19.0
                precision: 1024

But I need your help with Processor. At this time, it is not correct, because it is IDLE time of CPU (just for test).

I have totally 3 CPU OIDs as you can see below:

and I can think of two possibilities:

1. reverse the “systemStatusCpuIdle: 1.3.6.1.4.1.41916.11.1.16” - e.g.:100% - CpuIdle_value = CPU utilization
   or
2. sum of two OIDs (systemStatusCpuUser + systemStatusCpuSystem)
   1.3.6.1.4.1.41916.11.1.14 + 1.3.6.1.4.1.41916.11.1.15

I got the same result with both.

What do you think?

It is possible to go the way of simplicity and not create “Custom Processor Discovery and Polling” in file /opt/librenms/LibreNMS/OS/Viptela.php?

I’m afraid that my possibilities end here, I’m not a developer and I won’t be able to handle it.

Thank you.

Amazing work Cameron. Well done

So yes, you are right that this now needs custom PHP code.

Take the contents of this (https://p.libren.ms/view/raw/18b49f70) and replace what’s in /opt/librenms/LibreNMS/OS/Viptela.php with it.

If that all works for you please do create a pull request and share back to the community.

Thank you @laf .

Everything seems to be working fine.

I will create a pull request and share back to the community.

Thank you again for your cooperation.
