Monitor Types

JaxView includes different types of monitors. They are organized into five categories according to the type of measurement that they provide. The following table is a summary of the monitor categories, the names of the monitors in that category and a general description of the use and metrics provided.

JaxView Monitor Types

Category	Monitor Types	Description
Performance Management Monitors	Message Content Monitor Message Size Monitor Performance Monitor Total Usage Rate Monitor	These monitor intermediaries measure the performance of a Web service. They generate metrics such as round trip time and message sizes
Fault Management Monitors	Fault Content Monitor Fault Percentage Monitor Fault Rate monitor Service Compliance Monitor	These monitors are for measuring the fault rate and total fault count for a Web service. They can also monitor fault types
Client Metering Monitors	Client Access Monitor Client Usage Rate Monitor	These monitors are designed for measuring client usage of a web service. They also generate metrics around the number faults generated by the client usage and unauthorized attacks on the web service.
Active Monitors	SOAP Heartbeat Monitor REST Heartbeat Monitor Composite Monitor	Active monitors send a synthetic request to a Web service, on a schedule, and waits for a response. The user can then set a threshold on the round trip time and the value of the response from the Web service.
J2EE Monitors	Java Transaction API Monitor J2EE Container Server Log Monitor	These monitors will measure J2EE related metrics such as JTA Stats or J2EE server container logs.

Monitor Configuration Settings

The following sections describe the JaxView monitor configuration settings that you use to create or edit monitors in JaxView.

Note: The object assignment model used in JaxView is designed to make management of multiple services and monitors easy. It can, however, lead to some confusion. A single JaxView monitor configuration definition can be assigned to multiple service operations in the environment. After this assignment all instances of that definition continue to be linked via the definition in the Monitors tab. Any changes made to a single instance of that monitor will be made to all instances that use the same definition. See the section Object Assignment in JaxView for more information.

Message Content Monitor Properties

This monitor allows the user to monitor the contents of a message body and header for both request and response. This monitor is important for monitoring business activity of a Web service. The following are the metrics available from these monitors:

Metric	Description
Pattern Match Value	This metric will allow the user to measure any part of the content of the message including the header using regular expression. See the section JaxView Tools for examples of regular expression syntax.

The following are the configuration properties common to the Message Content monitor type:

Monitor Settings

Title (required): The title for this monitor. This title will be displayed in the Monitors object tree view as a reference to this alert
Description (optional): A short description for this monitor. For example, you can add a more detailed description of what systems are being monitored or information about the specific configuration settings.
Disabled:: Check this box to disable this monitor. Clear the box and click the Save button to re-enable the alert.
Caution: Disabling a single monitor definition will disable all instances of that monitor on the JaxView server.
Message Direction:: The pattern match should be done on the request or reponse.
Element Name:: A unique name what we are matching on. For example MSFT Stock Price.
Element Pattern:: In this field put a regular expression pattern that will match on the content of the message. See the example section below. See the section JaxView Tools for examples of regular expression syntax. There has to be one capturing group that the pattern matches on.

Baseline Settings

Use this section to configure optional measurement baseline calculations. This feature allows you to use statistical trending to dynamically set the event thresholds for the monitor based on other measurements taken during a previous interval. See the section Monitor Baselining in JaxView for more information.

Threshold Settings

Use this section to set the event thresholds for the monitor. The monitor status is set according to the threshold settings. See the Setting Monitor Thresholds section for more information about threshold settings.

Error Condition:: Set the monitor measurement condition that is considered to be a failure or critical performance threshold.
Warning Condition (optional):: Set the monitor measurement condition that is considered a warning threshold or degraded performance level.
Good Condition (optional): Set an optional monitor measurement condition below which the system performance is considered to be acceptable.

Message Content Element Pattern Matching Example

The following is an example of hoe the Element Pattern setting can be used.

If the Element Pattern content match expression was

/Copyright (\d*)/

and the content returned to the monitor by the request included the string:

then the match is made and the retained content match value would be:

2005.

This retained value can then be referenced in the Error Condition threshold using the form: Element Name: copyright date < 2004

In this case, if the content returned contains a value less than 2004, this monitor will report an error.

NOTE: XPath can also be used in the pattern field to find and match on values inside a SOAP XML message.. The expression will be of the form: XPATH:path/to/message/element

NOTE: Element pattern field can be left blank for this monitor. If the field is left blank then JaxView will search for the text result of the message and will set Pattern Match Value to it. For example if the response of a message contains the following

<env:Envelope
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
env:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:enc="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:ns0="urn:Foo"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance>">
<env:Body>
<ns0:test3Response>
<result xsi:type="xsd:string">
25
</result>
</ns0:test3Response>
</env:Body>
</env:Envelope>

And the Element Pattern field is set to blank, then the Pattern Match Value will be set to 25. So if the Error Condition threshold for this monitor was Error if Pattern Match Value > 24 then the monitor will be in error.

Message Size Monitor Properties

This monitor generates metrics about the size of the request and response message. The following are the metrics available from these monitors:

Metric	Description

Warning Condition (optional):: Set the monitor measurement condition that is considered a warning threshold or degraded performance level.
Good Condition (optional): Set an optional monitor measurement condition below which the system performance is considered to be acceptable.

Fault Content Monitor Example

The following is an exmaple of how to use the the Fault Content monitor for matching message content.

If the fault string is:

JAXRPCTIE01: caught exception while handling request: deserialization error: XML reader error: unexpected character content: "buzz"

you can use .* unexpected character content.* in the pattern field to match on this string.

The default thresholds for this monitor are that if the pattern 'matched' the monitor will report an error condition. The Pattern Match has to always be set to 'matched'. If you want to reverse the condition you can set it as follows

error if Pattern Match != 'matched'

good if Pattern Match == 'matched'

NOTE: XPath can also be used in the pattern field. The format will be XPATH:xpath string.

Fault Percentage Monitor Properties

This monitor will monitor the percentage of faults generated from requests. The monitor will look at the number of messages received for the last 3 hours and measure the percentage of the messages that generated the fault. Then a threshold is set on that percentage. There needs to be a steady state reached before the numbers are meaningful. For example if the monitor is just added and the first message is a fault then the percentage is %100, which could be meaningless. It is recommended that you let the monitor run for a minimum of 3 hours or record at least 100 messages before assigning a event notification rule and alert to it. The following are the metrics available from these monitors:

Metric	Description
Fault Usage Rate/Hour	This metric measures fault percentage of the total request into the operation.

SOAP Heartbeat Monitor Properties

This module allows for active monitoring of a Web service. It does that by creating a synthetic message, sends it to the Web service, and waits for a response. It performs this on a schedule, for example, every 5 minutes. The user can then set a threshold on both the result of the response and the round trip time. This essentially actively monitors the performance of a SOAP Web service. The following are the metrics available from these monitors:

Metric	Description
Response Time (msec)	This metric is the response time of a metric when measured from a specific client.
Response Value	When the request is made the response value of the Web service operation can be monitored. For example, if the operation measure reponds with the stock price, a threshold can be set on that price to trigger and alert.

J2EE Container Server Log Example

For example, if the fault string is JAXRPCTIE01: caught exception while handling request: deserialization error: XML reader error: unexpected character content: "buzz"

you can use .* unexpected character content.* in the pattern field to match on this string.

The default Error Condition thresholds for this monitor are that if the pattern 'matched' that would be an error condition. The Pattern Match has to always be set to 'matched'. So if one wanted to reverse the condition they would set as follows

error if Pattern Match != 'matched'

good if Pattern Match == 'matched'

Setting Monitor Thresholds

Setting event thresholds for monitors in JaxView is fundamental to efficient monitoring and SOA management. The monitor threshold is used to determine what are acceptable performance and content values and what values should be considered an event that requires notification and action.

You select the threshold metric you're interested in in the first drop down, then set a qualifier (for example > or >=) and then a value. The value could be a number or a string.

Note: If using a string then it needs to be wrapped in single quotation 'value'. Also the units for most performance related metrics are in milliseconds.

Some monitors have default thresholds for certain metrics. These are labeled with the text '(default)' in the threshold drop down list. If you do not explicitly set your own threshold settings the monitor will automatically use the default threshold for that specific monitor. It is recommended that you set your own thresholds for most metrics.
