DDM Probe Overview

DDM Probe Overview

Monitor configurations, errors and event statuses

Architected in three different styles:Scheduled

Embedded

Listening

Nine probe feature areas

Default probes available out-of-the-box

Standard configuration in Events4.nsf

Generate event report documents in DDM.nsf

What are DDM Probes?

DDM Probe Overview

3 different styles of ProbesScheduled - customizable or predefined schedule

Most of the default probes fall in this category

Embedded - instrument the feature area codeExample: “ATTEMPT TO ACCESS database … “ error

Listening – listens for errors to occurExample: Replication Errors Probe and Database Error Monitoring Probe

Default Probe Configuration Documents

DDM Probe Overview

Up to four sections to any given probe configuration documentBasics Section – probe type, subtype and description

Target Section – servers to run the probe and server, databases or processes to be probed

Specifics Section – configuration unique to each probe

Scheduled Tab – if configurable, specify when the probe should run

Probe Configuration Documents

DDM Probe OverviewProbe Configuration Documents

‘How should missed probes by handled?’Server down or hung

Missed Probes section on the Probe configuration document:

Ignore missed probeRun missed probe on startupRun missed probe at next time range

DDM Probe Overview

DDM provides console commands to:View probe scheduleView all enabled probes from events4.nsfRun probes manually

Probe Console Commands

DDM Probe Overview

View DDM probe schedule:sh sch –ddmShows a table of enabled probes and next scheduled run time


DDM Probe Overview

View enabled probes‘tell event dumpprobes’Shows a list of enabled DDM probes by note ID

Run probes manually‘tell event runprobe ?????’Run a probe with note ID ????? immediately (designed to be used with the dumpprobes command)


Probe Monitoring Scenarios

Monitoring Scenarios

Imagine ….

You are a Domino administrator and have a custom script or API set up to monitor replication of the NAB and other Domino system databases.

Maintenance of the custom solution is time consuming, especially scheduling the tool on multiple servers and tracking who is resolving which replication problems.

How can DDM help with replication monitoring?Scheduled Replication Checks and Replication Errors probes

Replication Probe Scenario


Imagine ….

You are responsible for monitoring Domino availability and performance.

There is an event report document in DDM that shows the Domino Directory search response is above the configured threshold, but the possible solution and probable cause information is not applicable in this particular case.

How do you customize DDM for your environment?Modify the Server Addin and Task Event document

Directory Probe Scenario


Imagine ….

You have been tasked to implement monitoring of pending mail due to recent problems with mail backlogs.

In addition, you have been asked to pay special attention to pending mail from your mail hub to executive mail server.

How can DDM help prevent messaging delays?Mail Flow Statistic Check and Transfer Queue Check probes

Messaging Probe Scenario


Imagine ….

You are the Domino Administrator, IT Architect or IT Manager. Maybe you work for a small company and your responsibilities include all three jobs!

There is a third-party vendor running a security audit of your company.

How can you leverage DDM to help prepare for this audit?Security Review and Security Configuration probes

Security Probe Scenario


Imagine ….

You are responsible for a domain of mixed OS machines.

You want to measure disk activity across the domain to determinewhich machines are getting hit the hardest in order to provide aload balancing scheme.

How can you use DDM to do this?Operating System Disk Probe

Operating System Probe Scenario


Imagine ….

You see an event in DDM that shows there is a corrupt database in your domain.

There is no “Choose Solution” button provided with the event, but you need to run fixup on the database when a problem like this occurs.

How can you customize the automated solutions in DDM?Write your own custom corrective action!
