This update introduces interface monitoring for oam,
mgmt and infra networks as a collectd plugin.
The interface plugin runs and queries the new maintenance
Link Monitor daemon for Link Model and Information every
10 seconds.
The plugin then manages alarms based on the link model similar
to how rmon did in the past ; port and interface alarms.
Severity: Interface and Port levels
Alarm Level Minor Major Critical
----------- ----- --------------------- ----------------------------
Interface N/A One of lag pair is Up All Interface ports are Down
Port N/A Physical Link is Down N/A
Degrade support for interface monitoring is add to the mtce
degrade notifier. Any link down condition results in a host
degrade condition like was in rmon.
Sample Data: represented as % of total links Up for that network interface
100 or 100% percent used - all links of interface are up.
50 or 50% percent used - one of lag pair is Up and the other is Down
0 or 0% percent used - all ports for that network are Down
The plugin documents all of this in its header.
This update also
1. Adds the new lmond process to syslog-ng config file.
2. Adds the new lmond process to the mtce patch script.
3. Modifies the cpu, df and memory threshold settings by -1.
rmon thresholds were precise whereas collectd requires
that the samples cross the thresholds, not just meet them.
So for example, in terms of a 90% usage action the
threshold needs to be 89.
Test Plan: (WIP but almost complete)
PASS: Verify interface plugin startup
PASS: Verify interface plugin logging
PASS: Verify interface plugin Link Status Query and response handling
PASS: Verify monitor, sample storage and grafana display
PASS: verify port and interface alarm matches what rmon produced
PASS: Verify lmon port config from manifest configured plugin
PASS: Verify lmon port config from lmon.conf
PASS: Verify single interface failure handling and recovery
PASS: Verify lagged interface failure handling and recovery
PASS: Verify link loss of lagged interface shared between mgmt and oam (hp380)
PASS: Verify network interface failure handling ; single port
PASS: Verify network interface degrade handling ; lagged interface
PEND: Verify network interface degrade handling ; vlan interface
PASS: Verify HTTP request timeout period and handling
PASS: Verify link status query failure handling - invalid uri (timeout)
PASS: Verify link status query failure handling - missing uri (timeout)
PASS: Verify link status query failure handling - status fail
PASS: Verify link status query failure handling - bad json resp
