ZenPacks.daviswr.Interfaces

My own take on the ethernetCsmacd family of templates to include multicast rates, broadcast rates, drop rates, queue length, and more thresholds.

Important

This will DOUBLE the number of datapoints polled per interface which could have a sizeable effect on the performance of your Zenoss system if you monitor a non-trivial number of interface-dense devices, like switches.

Unicast packet rate graphs will be reset due to a typo in Zenoss' original template naming. On 4.2.5, a combination of find and rename could be used to rename all ifInUcastPackets_ifInUcastPackets.rrd files to ifInUcastPkts_ifInUcastPkts.rrd and ifOutUcastPackets_ifOutUcastPackets.rrd to ifOutUcastPkts_ifOutUcastPkts.rrd. I don't know how one would go about renaming datapoints on 5+.

zProperties

Doesn't add anything new (yet), but sets the following if not already:

• /zInterfaceMapIgnoreNames
  • (ch.|docker|Extension|Filter|ISATAP|Kernel Debug|mgi|Miniport|RAS Async|Scheduler|Software Loopback|veth|vlan)
• /zInterfaceMapIgnoreTypes
  • (100BaseVG|Encapsulation Interface|HIPPI|IEEE 802.3ad Link Aggregate|Layer 2 Virtual LAN using 802.1Q|modem|Other|ppp|propVirtual|softwareLoopback|Voice)
• /Network/Firewall/ScreenOS/zInterfaceMapIgnoreTypes
  • (Encapsulation Interface|modem|softwareLoopback)

Really just my personal preference.

Usage

Modeling is handled by zenoss.snmp.InterfaceMap already, this overrides the ethernetCsmacd template at:

• /
• /Network/Switch/Dell
• /Server/Windows

And ethernetCsmacd_64 at:

• /
• /Network

Existing templates defined at those classes will be renamed during the install process.

If there are transforms in place for the /Status/Perf and /Perf/Interface event classes, new ones in this ZenPack won't be installed. Clear them before installation or apply the code snippets in the transforms directory of this repository manually. The revised /Status/Perf transform should help with spurious ifOperStatus ValueChangeThreshold events.
