Issue/Introduction

Reminder on Diagnostic Metrics :
  • Calculated metrics, based on raw metrics collected by Agents
Give information that is:
- Homogeneous across multiple OSs
- Easy to understand
 
  • Saturation
- CPU, memory, disk I/Os, network I/Os, and server
- Diagnostic Metric values then transformed into high level indicators
 
  • Utilization
- CPU, memory, storage space, network bandwidth
- In unit "RPI" (Relative Performance Index) for CPU
  • Used by Sysload Analyst Console built-in Dashboards and by built-in Sysload Portal reports


Environment

Sysload Agents

Resolution

Define Rules

The Agent is installed with a default configuration for diagnostic metric rules
  • This definition is located in the Collector main configuration file "sldrmd.ini"
You can overload this default configuration
  • By defining rules via the Console GUI, in Enterprise Models and by deploying those rules to Agents
  • This definition is located in the file "diagmetric.ini"
  • If a rule is not overloaded, then the default rule is taken into account

Diagnostic Metrics Definition and Deployment

Definition and deployment of diagnostic metrics via the Console GUI
  • Via Enterprise Models
- Define once, deploy to many
- Different User access rights can be defined on different Enterprise Models
 
Facilitates configuration and tracking of the configuration done on Agents (Monitored Objects)
- Leads to better rules defined and better reporting on server performance and capacity reports

Enterprise Models
 

Rule Set

One item in an Enterprise Model can be used to define rules for defining one or more rules
  • The management unit (what you define) is hence a Rule Set

Edit Diagnostic
 

• Weight

- A weight is defined for the Rule Set
- This weight is used when deploying the Rule Set to Agents/Monitored Objects
  • Indeed, a Rule that you are deploying via a Rule Set may already be defined on the target Agent
  • Your Rule in your Rule Set will overwrite the Rule already defined on the target Agent only if your weight is greater than the weight of the rule already defined
  • You get a deployment report to track deployment successes and failures

Rule Definition

  • A rule is based on:
Formula
  • Based on raw metrics (collected by the Agent)
  • And / Or based on variables (values collected by the Agent but not exposed by the Agent as metrics)
Duration
  • A duration during which the formula must be true for saying there is saturation

Rule Definition 2


Diagnostic Metrics Definition

  • By default, the Console shows a subset of the configurable rules/metrics only
- Those that are usually tuned by customers
- Others are hidden; to show them, activate a User Preference
 
Reminder

You can import a pre-defined set of diagnostic metric rules into an Enterprise Model
  • Create an Enterprise Model and open it
  • Click on the right mouse button and select "Import Diagnostic Metrics > From a file"

Additional Information

Deploying Diagnostic Metric Rule Sets

  • Similar to Enterprise Entities and Alerts
- Right mouse button anywhere in the Enterprise Model, Select "Deploy Diagnostic Metrics"
- No Agent Collector restart required
  Remember: The Weight may prevent a Rule deployment
  • On the first deployment of a Rule Set to an Agent, the file "diagmetric.ini" contains all the rules necessary to all the diagnostic metrics
- Even if you had a single rule defined in your Rule Set
- Default rules configured during the Agent installation (in the file "sldrmd.ini") are duplicated (in the file "diagmetric.ini")
- The rules in the file "sldrmd.ini" are then always ignored


Checking Rules Deployed

  • The Console GUI can display the whole set of rules defined on a Agent/Monitored Object
- Right Mouse button on a Monitored Object, then select "Modify parameters > Display Diagnostic Metrics"
- The panel indicates the rules for each Diagnostic Metric
  • Whether the rules come from the default Agent configuration or via an Enterprise Model
