Unified Assurance Metric Service-Level Management (SLM) Collector

Overview

The Unified Assurance Metric Service-Level Management (SLM) Collector leverages Service Hierarchies with weights to generate SLM availability metrics. To that end, it allows administrators to create and manage metric-based services and their relationships with thresholds.

Metric Service-Level Management (SLM) Collector Setup

  1. Navigate to the SLM "Service Management" UI and define a service hierarchy:

    Configuration -> Service Management

    An additional example of creating a SLM service is available via the documentation:

    SLM Service Example

  2. Enable the default Service, unless a specific configuration option is needed.

    Configuration -> Broker Control -> Services

Default Service

Field Value
Package Name coreProcessing-app
Service Name Metric SLM Collector
Service Program bin/core/processing/MetricSLMEngined
Service Arguments
Service Description Metric SLM Collector
Failover Type Standalone (Supported: Standalone, Primary/Backup)
Status Disabled
Privileged (Unchecked)

Default Configuration

Name Value Possible Values Notes
CheckTime 900 Integer This entry is used to check the service hierarchy for changes the specified number of seconds.
LogFile logs/MetricSLMCollector.log Text, 255 characters Relative path to Log File.
LogLevel ERROR OFF, FATAL, ERROR, WARN, INFO, DEBUG Logging level used by application.
PollTime 60 Integer How often will look for services to analyze in seconds (independant of the SLM service polltime).
Threads 3 Integer The number of processing threads created.
DBThreads Integer Optional - Number of database threads to be created. If not specified, defaults to a third (rounded up) of "Threads" application configuration.
PreferIPv4 Disabled Enabled/Disabled Optional - Controls whether or not to prefer IPv4 transport for Devices. This option is only considered if both IPv4 and IPv6 are available for a device. If this config is missing, IPv6 will be preferred.

$DATE_TEXT Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value Long date
$DATE_EPOCH Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value UTC epoch
$POLLER Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value Name of SLM Collector engine: 'SLMCollector'

$SAMPLERATE Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value Threshold sample rate: 1
$COMPARE Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value Threshold value
$VALUE Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value Calculated value
$UTIL Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value Calculated utilization (for services it is the same as $VALUE)
$STATUS Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value Calculated metric Status (Availability) (for services it is the same as $VALUE)
$METRICID Email, Syslog, Trap Email{Subject, Body}, Syslog, Varbind (#) Value Metric ID of the threshold metric
