Snmp observ lib

[v-zhuravlev]

This is universal SNMP dashboard and alerts supporting multiple network vendors.

There are two tiers of dashboards (using layout you can find for Linux or Windows)

• Fleet to add network overview
• Overview to give more details about
• logs dashboard based on syslog received messages from devices.

This observ lib relies on snmp_exporter modules of version 0.28.0 or above. Please see README.md for information which snmp_exporter modules should be used to poll metric groups below:

Currently supported metrics groups:

• Interfaces stats like unicast,broadcast,multicasts,errors and octets in/out (all devices)
• CPU (mikrotik,dell,cisco,juniper,dlink,eltex,ubuquiti airos(old))
• Memory (mikrotik,dell,cisco,juniper,dlink,eltex,ubuquiti airos(old))
• sensors (temperature etc) (for Cisco and Juniper only for now)
• FRU status (for cisco , optional row)
• Fibre channel (for cisco MDS only, optional row)

Note: more vendors will added once they are supported by snmp_exporter. As well as more metric groups will be added to existing vendors.(like adding support for temperature sensors etc).

Alerts:

• Interfaces, Fibre channel errors, SNMP exporter, reboot, cpu and memory usage are controlled.

Annotations:

• Dashboards support annotations when relevant alerts start firing as well as critical alerts are found recevied from syslog.

Datalinks:

• Fleet table and fleet panels supports data links to drill down to instance of intereset.

Examples:
Fleet overview:
0)
note: transmitted/received in table is empty is due to static counters from emulated devices. They actually work. :)

Couple comments to address, but overall this looks VERY nice! Fantastic job Vitaly!

Thanks for addressing the comments @v-zhuravlev, all looks mostly good though I think two comments got hidden by Github (wish that could be disabled...) so if you could address those I'd be happy to approve :)

1. New fleet table, now more compact with 5 columns merged:

Kept job though, as it is not always the case that grouplabels would be identical.

2. Updated interfaces table, dropped group/instance labels from there as table is intended to be used with single instance(device) only.

Awesome work Vitaly, thank you for addressing all the feedback! LGTM :)
