Introduction
- Notifications are managed from the Configuration-> Notification sub>Notification sub-view.
- The configuration format of notifications is XML. The JOC Cockpit offers an XSD schema-aware XML Editor for configuration purposes.
XSD Schema locations
- JS7 release 2.0 and newer:
The configuration is applied by the JS7 - Monitor Service which that inspects the workflow execution history and creates notifications as required.
- Changes to the configuration are applied by the Monitor Service immediately.
Notification View
The Notification View allows the configuration to be managed Configuration->Notification sub-view allows to manage the configuration like this:
Explanation:
- If this view shows an empty configuration then the "New" button can be used to created a configuration.
- Alternatively, a configuration can be added with the "Upload" button. A configuration sample is available from the
jetty_base/resources/xsd/notifications/notification.xml-example
file.
Configuration
Structure and Elements
The configuration makes use of the following base elements, which are available from the Configurations root element.
- Fragments: Define re-usable configuration blocks for Messages, Monitors and monitored Objects.
- MessageFragments
- Message
- Defines the content which is sent, for example, by mail to a user or which is used to parameterize a command line utility, such as content to be forwarded to a System Monitor.
- Messages for use with E-Mail represent the mail body, either for use with plain text or with HTML e-mails.
- Messages for use with the Command Line represent a string that can be used with the Notifications/Notification/NotificationMonitors/CommandFragmentRef element, see below.
- Message elements can include Monitor Variables that are placeholders for values, e.g. for the Workflow Path, Order ID etc.
- Any number of Message elements can be added.
- MonitorFragments. These fragments come in a number of flavors for the following notifcation types.
- MailFragment
- The following elements are required to send mail:
- MessageRef: Specifies the reference to a Message element that provides the mail body.
- Subject: Specifies the mail subject and can include Monitor Variables.
- To: Specifies the e-mail address of the recipient. Multiple recipients can be separated by comma.
- The following elements are optional to send mail:
- CC: The recipient of carbon copies. Multiple recipients can be separated by comma.
- BCC: The recipient of blind carbon copies. Multiple recipients can be separated by comma.
- From: The e-mail address of the account that is used to send mail. Consider that your mail server configuration determines whether a specific or an arbitrary account can be used.
- For details see JS7 - Notifications Notification - Configuration Element MailFragment
- CommandFragment
- MessageRef: Specifies the reference to a Message element which provides the content that is to be forwarded with the Command element. The message content is available from the
${MESSAGE}
Monitor Variable for use with later elements. - Command: Specifies the shell command for Linux/Windows which is used to forward notifications, to, for example, a System Monitor Agent utility.
- The example notification view above makes use of a shell command like this:
echo "${MESSAGE}" >> /tmp/notification.log
- The
echo
shell command appends the content of the ${MESSAGE}
Monitor Variable to a file in the /tmp
directory.
- For details see JS7 - Notifications Notification - Configuration Element CommandFragment
- JMSFragment
- NSCAFragment
- This fragment type is used for direct connections to System Monitors that operate a Nagios-compatible NSCA service for passive checks such as Nagios®, Icinga®, Opsview®. This fragment type makes use of the JSend NSCA Java API.
- The required connection attributes such as host, port, timeouts are specific to the System Monitor being used.
- Note that JSend NSCA can be used without encryption or with an XOR or TRIPLE_DES encryption. Additional encryption schemes are not supported.
- For details see JS7 - Notifications Notification - Configuration Element NSCAFragment
- ObjectFragments
- Workflows: Any umber of workflow configurations can be added and are distinguished by a unique name that is added to this element.
- Workflow: A specific workflow can be specified by, for example, its name. The path attribute allows a regular expression to specify a part of the workflow path.
- WorkflowJob: This element can be used to limit notifications to specific jobs in a workflow.
- This includes the option of specifing the job name and/or its label.
- It is necessary that the criticality, which can be one of ALL, NORMAL or CRITICAL, is specified when using this element.
- The return_code_from and return_code_to attributes can be optionally used to further limit notifications to jobs which complete with the given return code. The return code for shell jobs corresponds to the OS exit code.
- Notifications: Define the effective notifications by references to the Fragments elements described above.
- Notification: Any number of notifications can be added with each norification being distinguished by a unique name. A notification is assigned a type which can be any one of SUCCESS, WARNING or ERROR. This allows notifications which are used, for example, in the event of job errors and warnings to be specified. This also allows notifications to be specified for successful workflow execution. Note that successful execution includes both the absence of job errors and optionally the presence of job warnings.
- NotificationMonitors: Selects one or more of the above MonitorFragments. It is possible to select multiple fragments of the same fragment type.
- CommandFragmentRef: Selects the CommandFragment to be used.
- MessageRef: Selects the Message element to be used with the Command.
- MailFragmentRef: Selects the MailFragment to be used in order to send notifications by mail. If multiple MailFragment elements are referenced then different types of mail, e.g. for different recipients or with different content and layout of the mail body can be used.
- NSCAFragmentRef: Selects the NSCAFragment to be used for direct integration with a NSCA compatible System Monitor.
- JMSFragmentRef: Selects the JMSFragment to be used to send notifications to a Java Message Queue compatible product.
- NotificationObjects: Selects the workflows which notifications are created for.
- WorkflowRef: Selects a Workflows element that limits notifications to their respective workflows. Any number of workflow references can be added.
Monitor Variables
- Syntax
- All variables have to be used with the following syntax, independently of the operating system in use:
${VARIABLE_NAME}
- Scope
- The Message element can include Monitor Variables: users can select the variable names from the below list of variables and use for example
${MON_N_CREATED}
. - The Command elements can include Operating System Variables: users have to prefix variable names from the below list with
JS7_
to use for example ${JS7_MON_N_CREATED}
.
