1 Overview

The Command Execution Policy Page is used to create and edit the Command Execution policy. The Command Execution policy can then be added to a Policy Group for deployment onto a managed node.

The command execution policy page is found by navigating to the policy view page and either creating or selecting a Command Execution policy.

2 Tabs

Tabs run down the left hand side of the view. Clicking on a tab will change the page that allows for a particular part of the policy to be modified. They are: Overview, Attributes, Conditions, Node Overrides, Schedule, Audit Log and View Data.

2.1 Overview

NAME The title of the policy that can be used to tell the policy apart from others

DESCRIPTION Describes the policy and explains what it does

TYPE Command Execution

NODE OVERRIDES CONDITIONS Enabling this slider makes the Node Overrides tab visible.

2.2 Attributes

EXECUTABLE The full path (including the binary) of the executable to run. Don't include arguments here, there is a separate field for that below

INITIAL DIRECTORY Also known as the current working directory, this is a location in your filesystem to start running the executable from. This can help the executable/script to find any configuration or other files that need to reside in the same file location as itself.

ARGUMENTS The parameters that are given after the name of the program are known as Command Line Arguments. Veloopti provides a way of passing these to the executable/script.

VALUE

If there are more than one argument then they are joined together separated by a space character.

ENVIRONMENTAL VARIABLES Veloopti can add an environment variable that may be used by the program as as a part of the standard environment variable set. Once the program completed the environment variable ceases to be available.

NAME The name of the variable. This is the part that appears before the =

VALUE The value of the variable. This is the part that appears after the =

2.3 Conditions

Click on the 'add' button to the right to add a condition rule. The rules may be moved up and down by clicking on the rule changing its position. Click on the [Add] button to bring up the dialogue to add a condition to the policy.

NOTE: Currently changing the position of order of the rules does not do anything as they are evaluated in order of severity.

SEVERITY The severity that appears on the event that is raised by a threshold violation of the rule

EVENT SHORT DESCRIPTION The short event description that appears on the event that is raised

EVALUATE

Either add a new row by clicking on the [Add] button or click on an existing row to enter the edit condition dialogue box.

Metric Select a metric upon which to perform a threshold evaluation. The options available are:

Standard Out (text)

Standard Out (Number)

Error Out

Exit Code

Run Duration (seconds)

Timed out

OperatorSelect an operator to perform against the Metric above. Different options are available for different metrics.

Equals

Contains

Doesn't Contain

Does not equal

Regular Expression Match

Regular Expression Suppress Matches

Value Enter a value to compare the metric against using the operator.

BREACH AND RESET

Breach duration Enter the number of consecutive breaches that need to occur for an event to be raised

Reset Duration Enter the number of consecutive reset conditions, the number that the metric must be (usually) below, for the event severity to be set to Normal

CREATE EVENT

Event Severity The severity that appears on the event that is raised by a threshold violation of the rule

Event Short Description The short event description that appears on the event that is raised

Event Long Description The long description that appears in the event

Auto Action Select an action to run automatically when the condition of raising an event is met.

Close event if auto action runs successfully IF the auto actions runs successfully then the event will be closed.

EVENT ACTIONS These actions are available to be run by any user that has the "Run Action from Event" permission. Unlike normal actions it does not rely on the Action "Level" permission of Operator, Power User or Administrator

HELP TEXT This text appears on the event in the "Help" section.

NOTIFICATION WORKFLOW Select the Notification Workflow that will be used for notifications and escalations.

2.4 Node Overrides

One policy can run on multiple nodes using the same conditions to create events. Individual nodes may require different threshold values in these conditions for effective monitoring. This is known as a "Node override condition".

This is currently not enabled.

2.5 Schedule

TYPE

Basic Run the policy once per minute or once per hour

Time of day Run the policy once her day

Custom Run the policy on a complex schedule

EVERY

Basic Select "Minutes" or "Hours" and type when on the minute or hour the policy should run.

Time of day Select hour and minute and the weekday(s) that the policy should run.

Custom Select "Minutes" or "Hours" and type when on the minute or hour the policy should run. Select the time range when the policy should be active: e.g. 9:00am - 5:00pm. Welect the weekday(s) that the policy should run on.

2.6 Audit Log

DATE/TIME The date/time that the audit event occurred

USER The user that initiated the audited event

EVENT A description of what happened to the policy. Blue text indicates that it is a link to the described item.

ACTION If an action is available for the audit item it can be initiated here. For instance, roll back the policy to the previous version or restore the accidentally deleted policy.

2.7 View Data

SELECT YOUR NODE Use the drop down list box to select the node that it is deployed to. Graphs will then be visible in the below space that contains the metrics that have been collected over the last hour.

NOTE: Only nodes with this policy currently deployed are able to be selected.
