Data Types

Action

An action represents a consequence of an event.

An Action object represents a particular action linked with a specific event.
Action objects are generated by the Alerting engine and processed by plugins.
An Action object stores the eventId property and optionally may contain the full Event object.
An Action may store the result of the processing by a plugin.

Name Required Description Type Allowable Values Default Value

ActionDefinition

An action represents a consequence of an event.

Actions are processed by plugins, and plugins offer a map of properties to personalize an action.
An ActionDefinition stores which properties will be used for a specific action in a specific plugin.

A Trigger definition can be linked with a list of action definitions.

Alert engine will instantiate a specific Action based on its ActionDefinition.

In a similar way as TriggerAction an ActionDefinition can add optional constraints that determine
when an action will be executed.

- A set of Alert.Status (represented by its string value).
The action will be executed if the Alert which is linked is on one of the states defined.
Unlike Alerts, Events don’t have lifecycle, TriggerActions on Events are all executed at Event creation time.

- A TimeConstraint object that defines a time interval in absolute or relative way.
The action will be executed if the action creation time is satisfied by the time interval.
If a TriggerAction does not define any constraint, ActionDefinition constraints will be used.

Alert

Alerts are generated when an Alert Trigger fires, based on a set of defined conditions
that have been matched, possibly more than once or have held true over a period of time.

When fired the trigger can perform actions based on plugins (e-mail, sms, etc).

Alerts then start moving through the Open, Acknowledged, Resolved life-cycle.

- Open status represents an alert which has not been seen/taken yet by any user.
- Acknowledge status represents an alert which has been seen/taken by any user and it is pending resolution.
- Resolved status represents an alert which problem has been resolved.

Alerts can be resolved automatically using AUTORESOLVE Trigger conditions or manually via API.

Alert can attach a list of notes defined by the user.

There are many options on triggers to help ensure that alerts are not generated too frequently,
including ways of automatically disabling and enabling the trigger.

Dampening

A representation of dampening status.

It’s often the case that you don’t want a trigger to fire every time a condition set is met.
Instead, you want to ensure that the issue is not a spike of activity.
Hawkular Alerting provides several ways of ensuring triggers fire only as desired.

This is a Trigger Dampening in Hawkular Alerting terminology.

Dampening types:

STRICT

- N consecutive true evaluations.
- Useful for ignoring spikes in activity or waiting for a prolonged event.

RELAXED_COUNT

- N true evaluations out of M total evaluations.
- Useful for ignoring short spikes in activity but catching frequently spiking activity.

RELAXED_TIME

- N true evaluations in T time.
- Useful for ignoring short spikes in activity but catching frequently spiking activity.
STRICT_TIME

- Only true evaluations for at least T time.
- Useful for reporting a continued aberration.

STRICT_TIMEOUT

- Only true evaluations for T time.
- Useful for reporting a continued aberration with a more guaranteed firing time.

EventCondition

An EventCondition is used for condition evaluations over Event data using expressions.

Expression is a comma separated list of the following 3 tokens structure:

<event.field> <operator> <constant> [,<event.field> <operator> <constant>]*

<event.field> represent a fixed field of event structure or a key of tags.
Supported fields are the following:
- tenantId
- id
- ctime
- text
- category
- tags.<key>

<operator> is a string representing a string/numeric operator, supported ones are:
"==" equals
"!=" not equals
"starts" starts with String operator
"ends" ends with String operator
"contains" contains String operator
"match" match String operator
"<" less than
"⇐" less or equals than
">" greater than
">=" greater or equals than
"==" equals

<constant> is a string that might be interpreted as a number if is not closed with single quotes or a string constant if it is closed with single quotes
i.e. 23, 'test'

A constant string can contain special character comma but escaped with backslash.
i.e '\,test', 'test\,'

So, putting everything together, a valid expression might look like:
event.id starts 'IDXYZ', event.tag.category == 'Server', event.tag.from end '.com'

A non valid expression will return false.

ExternalCondition

An ExternalCondition is used for condition evaluations performed outside of the Alerting engine.

The external engine will send StringData providing the data for which the external evaluation
has already evaluated to true.

The Alerting engine assumes a true evaluation for the data being sent in from the external engine. In other words, every ExternalConditionEval will have a true evaluation and therefore, for triggers with only a single external condition, and with default dampening, an alert will be fired for each data submission.

GroupConditionsInfo

A convenience class used in the REST API to POST a new Group Condition.

A group-level condition uses dataId tokens for the dataIds defined in the condition.
The group members must then replace the tokens with actual dataIds.

For example, we may define a group ThresholdCondition like ( $SystemLoad$ > 80 ).
Each member must then replace $SystemLoad$ with the actual system load dataId for that member.

The dataIdMemberMap is a map of the dataId tokens in the group conditions to the actual dataIds
used for the current member triggers.
Because most condition types have only one dataId the map will typically have 1 entry per condition.
But because a condition could have multiple dataIds (e.g CompareCondition has dataId and data2Id),
it may have more entries than conditions.
The inner map maps member triggerIds to the dataId to be used for that member trigger for the given token.
It should have 1 entry for each member trigger.

For example, let’s define a group trigger with two conditions:

ThresholdCondition( $SystemLoad$ > 80 )
ThresholdCondition( $HeapUsed$ > 70 )

If the group has two current members, with triggerId’s Member1 and Member2,
the map would look like this:

{
"$SystemLoad$":{"Member1":"Member1SystemLoad", "Member2":"Member2SystemLoad"},
"$HeapUsed$":{"Member1":"Member1HeapUsed", "Member2":"Member2HeapUsed"}
}

So, in the example the actual $SystemLoad$ dataIds would be Member1SystemLoad and Member2SystemLoad.
With this Map we can now add the group-level conditions and also the two member-level conditions
to each member

A NOTE ABOUT EXTERNAL CONDITIONS. <code>ExternalCondition.expression</code> will automatically have the
same token replacement performed. So, all occurrences of the dataId token found in the expression,
will be replaced with the mapping. This allows the expression of a group external condition to be
automatically customized to the member.

GroupMemberInfo

A convenience class used in the REST API to POST a new group Member Trigger.

A group-level condition uses dataId tokens for the dataIds defined in the condition.
The group members must then replace the tokens with actual dataIds.

For example, we may define a group ThresholdCondition like ( $SystemLoad$ > 80 ).
Each member must then replace $SystemLoad$ with the actual system load dataId for that member.
The dataIdMap is a map of the dataId tokens in the group conditions to the actual dataIds to
be used for the member being added. For example, assume the group trigger has two conditions defined:

ThresholdCondition( $SystemLoad$ > 80 ) and ThresholdCondition( $HeapUsed$ > 70 )

And now let’s assume we are adding a new member, Member1. The map would look like this:

{ "$SystemLoad$":"Member1SystemLoad", "$HeapUsed$":"Member1HeapUsed" }

So, in the example the actual dataIds would be Member1SystemLoad and Member1HeapUsed.
With this Map we can now add the new member trigger.

A NOTE ABOUT EXTERNAL CONDITIONS. ExternalCondition.expression will automatically have the
same token replacement performed. So, all occurrences of the dataId token found in the expression,
will be replaced with the mapping.
This allows the expression of a group external condition to be automatically customized to the member.

RateCondition

A threshold condition against rate of change over time.

Typically used for "counter" metrics, that continuously increase or decrease.
Given the last two datums for dataId:

deltaTime = datum.time - prevDatum.time
deltaValue = datum.value - prevData.value
periods = deltaTime / <conditionPeriod>
rate = deltaValue / periods
match = rate <conditionOperator> <conditionThreshold>

In other words, take the rate of change for the most recent datums and compare it to the threshold.
For example,
Let’s say we have a metric, sessionCount, that increments for each new session. If the sessionCount increases too quickly, say more than 20 per minute, we want an alert. We’d want:

RateCondition( 'SessionCount', INCREASING, MINUTE, GT, 20 )

By specifying the SessionCount data as increasing, we know to ignore/reset if the previous session count is less than the current session count. This indicates that maybe the counter was reset (maybe due to a restart).

Note that rate of change is always determined as an absolute value. So threshold values should be >= 0.

TimeConstraint

Define a time interval (startTime, endTime) used as a constraint for action execution.
Time interval can be defined in a absolute or relative expression.

An absolute time interval uses the pattern yyyy.MM.dd[,HH:mm] for startTime and endTime properties.
For example, these representations are valid absolute expressions for time interval:

{startTime: "2016.02.01", endTime: "2016.03.01", relative: false}
{startTime: "2016.02.01,09:00", endTime: "2016.03.01,18:00", relative: false}

Absolute time interval are marked with flag relative set to false.
Hour and minutes can be optional in absolute format, by default it takes 00:00 value.
The absolute interval time is based on the default time zone and locale.

A relative interval is used for repetitive expressions.
It can be defined an interval between months (i.e. December to March), between days of the week
(i.e. Sunday to Friday), between hours and minutes (i.e. 23:00 to 04:30), or a combination of month,
day of the week and/or hours and minutes.
Relative interval uses the pattern [MMM],[WWW],[HH:mm] where months and days of the week can be used in long or short format.
Same pattern should be applied to both startTime and endTime properties.
For example, these representations are valid relative expressions for time interval:

{startTime: "Jul", endTime: "Dec", relative: true}
{startTime: "July", endTime: "December", relative: true}

All dates within July and December months will be valid.

{startTime: "Jul,Mon", endTime: "Dec,Fri", relative: true}
{startTime: "July,Monday", endTime: "December,Friday", relative: true}

All dates within July and December months and within Monday and Friday days are valid.
So, a Sunday day of August will not be valid according previous example.

{startTime: "Jul,Mon,09:00", endTime: "Dec,Fri,18:00", relative: true}
{startTime: "July,Monday", endTime: "December,Friday", relative: true}

All dates within July and December months and within Monday and Friday days and time between 09:00 and18:00 are valid.
So, a Monday day of August at 18:01 will not be valid according previous example.

{startTime:"Monday,09:00", endTime:"Friday,18:00", relative: true}
{startTime:"Mon,09:00", endTime:"Fri,18:00", relative: true}

All dates within Monday and Friday day and time between 09:00 and 18:00 will be valid.
So, a Monday at 18:01 will not be valid according previous example.

{startTime:"July,09:00", endTime:"August,18:00", relative: true}
{startTime:"Jul,09:00", endTime:"Aug,18:00", relative: true}

All dates within July and December months and time between 09:00 and 18:00 are valid.
A day of August at 18:01 will not be valid according previous example.

{startTime:"09:00", endTime:"18:00", relative: true}

All times within 09:00 and 18:00 are valid.

TimeConstraint object can define if a given date will be satisfied within the interval or
outside interval using the property inRange.
A value inRange == true means that a time interval will be satisfied when a given date is
within the interval (taking the limits as inclusive), in case of inRange == false a given date
will be satisfied if it is outside of the interval.
By default, inRange == true.
For example,

{startTime:"09:00", endTime:"18:00", relative: true, inRange: true}

All times within 09:00 and 18:00 are satisfied by the interval.

{startTime:"09:00", endTime:"18:00", relative: true, inRange: false}

All times from 18:01 to 08:59 are satisfied in the interval.

When the auto-resolve condition set is satisfied, or if the Trigger is reloaded (manually, via edit, or at startup), the trigger returns to FIRING mode.

The mode is also needed when defining a trigger, to indicate the relevant mode for a conditions or dampening definition.

UnorphanMemberInfo

A convenience class used in the REST API to un-orphan an orphan group Member Trigger.

A group-level condition uses dataId tokens for the dataIds defined in the condition.
The group members must then replace the tokens with actual dataIds.

For example, we may define a group ThresholdCondition like ( $SystemLoad$ > 80 ).
Each member must then replace $SystemLoad$ with the actual system load dataId for that member.
The dataIdMap is a map of the dataId tokens in the group conditions to the actual dataIds to
be used for the member being added. For example, assume the group trigger has two conditions defined:

ThresholdCondition( $SystemLoad$ > 80 ) and ThresholdCondition( $HeapUsed$ > 70 )

And now let’s assume we are adding a new member, Member1. The map would look like this:

{ "$SystemLoad$":"Member1SystemLoad", "$HeapUsed$":"Member1HeapUsed" }

So, in the example the actual dataIds would be Member1SystemLoad and Member1HeapUsed.
With this Map we can now add the new member trigger.

A NOTE ABOUT EXTERNAL CONDITIONS. ExternalCondition.expression will automatically have the
same token replacement performed. So, all occurrences of the dataId token found in the expression,
will be replaced with the mapping.
This allows the expression of a group external condition to be automatically customized to the member.
