Tier management

NAM Server ► Settings ► APM model ► Business units

Manage tiers using the Business units screen on the NAM Server. This screen enables you to add, modify, and delete tiers.

For an introduction to tier concepts, see Multi-tier reporting.

  1. Log on to the NAM Server as a user with administrative rights.

  2. Go to the Business units screen.

    Access options:

    • From the NAM Server menu, choose Settings ► APM model ► Business units.
    • From the NAM Console top menu, choose Configuration ► Tiers, applications and transactions, and then choose the server. When you open Business units for the first time, the Tiers section shows the tiers resulting from the default configuration. For more information, see Multi-tier reporting.

The tiers are divided into three sections:

  • Client tiers
    This section shows tiers based on the transactions originating from Enterprise Synthetic agents or from passive monitoring devices, such as NAM Probes. You cannot modify these tiers, but you can view their contents. For more information, see Solution-specific tiers.
  • Network tiers
    This section shows four tiers based on the site definitions or the network-related data. These tiers cannot be added or deleted. You can modify the Client network and Network tiers. For more information, see Network Tiers.
  • Data center tiers
    This section shows tiers based on the traffic analyzer data. In this section you can define your own tiers. For more information, see Data center tiers and User-defined tiers.

All listed tiers are marked by icons:

Front-end tier icon = Front-end tier.

Non-front-end tier icon = Regular tier (not front-end).

To change tier sequence, use the up and down arrows:

When configuring tiers, note that each tier is described by its name and position in the tiers sequence.

Configuring tiers on NAM Server

Use the Business Units screen to configure tiers so you can view the full scope of your monitored environment.

Before configuring tiers ensure that:

  • You have established the sniffing points. For more information, see Install NAM Probe.
  • You have configured the software services in the NAM Console.
  • You have configured the sites and all of your client locations that belong to those sites.
  • You are familiar with the concept of a front-end tier. Multi-tier reporting. When configuring tiers on the NAM Server, be sure to consider the following recommendations:
  1. The default configuration of network tiers assumes that the Client network tier matches all client traffic and the Network tier matches traffic within your data center (for the All Other site only). If you suspect that the All other site may include client traffic, modify the Client network and Network tier definitions. For more information, see Network tiers.
  2. If you use presentation servers, such as Citrix or Windows Terminal Services, and you have configured the software services based on the ICA analyzer, the Citrix/WTS (presentation) tier will automatically match the ICA-based traffic. You cannot modify this tier. For more information, see Citrix/WTS (presentation) tier.
  3. By default, there are several tiers that present measurements originating from Network Application Monitoring and automatically match the traffic based on the different analyzer types. You can remove these tiers but you cannot modify their configuration rules. For more information, see Data center tiers.
  4. If the automatically configured tiers are not corresponding well to your application infrastructure, create your own tier definitions. For more information, see User-defined tiers.
  5. Review additional information if you use other Dynatrace components and solutions, such as Enterprise Synthetic, WAN Optimization, or the sequence transactions on the NAM Probe. For more information, see Solution-specific tiers.
  6. Note that the configuration of tiers is global for all applications. If you have configured tiers, to see the layered view of your applications, view the Applications and transactions section to configure the applications and transactions.

Setting the order of tiers

Set the order of tiers so that it represents the infrastructure for your applications and enables you to see the application delivery chain starting from a client to the last server in the data center. Setting the sequence of tiers affects the order they are presented on Tiers report. Each NAM Server installation has a built-in sequence that is meant to reflect a typical data center to user network and application layers.

Change the order of the tiers by clicking the arrow icons () next to each tier name. Repeat this action for each tier to move. The new sequence is automatically saved.

User-defined tiers

The tiers that can be modified are listed in the Data center tiers section. You can also add new tiers to the data center tiers group, based on the data provided by Network Application Monitoring.

Data center tiers

Tiers that present measurements originating from Network Application Monitoring and that are based on the different analyzer types are listed in Data center tiers section.

By default, the following tiers are available:

  • Website
    Based on the Web analyzer group and includes HTTP, SSL, and SSL Decrypted analyzers
  • Oracle Forms
    Based on the Oracle Forms analyzer group.
  • SAP
    Based on the SAP analyzer group.
  • Exchange
    Based on the Exchange analyzer.
  • Middleware Based on the Middleware analyzer group, including Jolt, SOAP, SAP RFC, and XML analyzers.
  • Message Queue Based on the IBM MQ analyzer.
  • Database Based on the Database analyzer group, including DRDA (DB2), Informix, Oracle, SQL Server Resolution Protocol, and TDS analyzers.
  • Data center infrastructure Based on the Datacenter Infrastructure analyzer group, including DHCP, DNS, Generic (with transactions), ICMP, IP, Kerberos, NetFlow, Non IP, SMB, SMTP, LDAP and UDP analyzers.
  • Authentication Based on the LDAP analyzer group.

Tiers are configured globally. Do not create separate tiers for individual applications. To see the layered view for a specific application, configure the application and its transactions on the NAM Server.

  • Restore a previously deleted tier based on analyzer. For more information, see Adding an analyzer-based tier.
  • Change the sequence of tiers so it fits your application infrastructure. For more information, see Setting the order of tiers.
  • Configure applications and transactions in the Applications and transactions section.

Adding a software service-based tier

To add a new tier based on data coming from NAM:

  1. Click Add and select Software service-based tier.

  2. In the dialog box, type the tier name and click OK.

  3. Optional: If the new tier is a front-end tier, select the Make front-end tier check box in the Properties section.

    This enables you to indicate that this tier is regarded as the closest tier to a user. More than one tier can be set as a front-end tier.

  4. In the Rules for this tier section, click Add rule.

  5. Choose a software service.

    Click the field labeled Software service and start typing. A list of all available software services appears. Select the required service and it is immediately added to the rule.

  6. Define optional rule components.

    Server IP address

    Enter IP addresses of servers to be included in the rule (non-matching servers will be excluded). You can enter only one address per line. Only full addresses are supported.

    An empty Server IP address matches any IP address. Note that an empty field will be replaced by the “*” (asterisk) symbol.

    Type

    Choose the reporting hierarchy level: Operation, Task, Module, or Service. You can also choose Expression to create detailed rules.

    Label

    By default, the Label field is filled with a single asterisk that matches all operations or other entities selected in the Type list.

    Choose operation or another entity (matching the Type selection). Depending on your choices in the Type column, you will be able to select values filtered by matching criteria.

    To exclude a given entity from the rule, you can surround the string to be excluded with the character combination “~() ”. For example, if you are defining a transaction as a container for SQL operations and want to exclude all SELECT operations, use the following structure:

    ~(SELECT *)

    Operations or other hierarchy levels (for example, tasks or modules) are not shown on the reports for the given business unit.

    Note that an exclude rule can be the only definition in the Label field. Negation can be used in combination with any hierarchy level set in the Type column.

    For expressions, use the following structure:

    parameter1="value1",parameter2="*mask2"

    Expressions consist of parameters and their values. You can use the following parameters: operation, task, module, service, host, method, and protocol . They must be separated by commas, with no spaces.

    Parameter values must be enclosed in quotation marks. Examples:

Example expressions
Example expressions

If the expression is invalid, a warning icon appears next to the Label field.

The report server database is updated immediately after the rule constituents are entered.

Adding an analyzer-based tier

Add tiers based on analyzers or analyzer groups that the NAM Server understands. Follow the directions below to add a tier that has been deleted and was a part of the default report server configuration.

To recreate a previously deleted tier based on analyzer or analyzer group:

  1. Click Add and select Analyzer-based tier.

  2. In the dialog box, type the tier name and click OK.

  3. Select the analyzer or analyzer group in the Analyzer type section.

    The available options are grouped in Analyzer groups or Analyzers sections. Adding tiers based on the analyzers that already belong to an analyzer group on the NAM Server is not supported.

  4. Optional: If the new tier is a front-end tier, select the Make front-end tier check box in the Properties section.

    This enables you to indicate that this tier is regarded as the closest tier to a user. More than one tier can be set as a front-end tier.

The report server database is updated immediately after the rule constituents are entered.

Modifying a tier on the NAM Server

To modify a tier:

  1. In the Data center tiers section, select a tier and click Modify.
  2. On the Tier Definition screen:
    1. Optional: Type the new name for the tier in the Name field.

    2. Optional: Change the selection of the Front-end tier check box.

      Select the Front-end tier check box to indicate that this tier is regarded as the closest tier to a user.

    3. Optional: Modify the tier rules.

      • Click Add to define a new rule.
      • Select a rule and click Modify to change the definition of the existing rule.
      • Select a rule and click Delete to delete that rule from the tier definition.
  3. Click OK to submit the changes.

Network tiers

If you have configured sites on the NAM Server or if sites have been configured automatically, the Client network and Network tiers will automatically be displayed on the Tiers report. By default, the Client network tier shows traffic for all sites except the All other site and the Network tier shows traffic for the All other site only.

If you suspect that the All other site may include client traffic, you should modify the default configuration of the Client network and Network tiers. See Modifying a network tier below.

When the “All Other” site includes client traffic

The following are examples of when the All other site may include client traffic:

  1. The assignment of clients to sites is imprecise.

    This may happen when you are not sure whether all client locations were assigned to the appropriate sites.

  2. Sites were configured automatically based on either AS names or CIDR blocks, where a block is defined by an IP address and a network mask.

In either case, modify the Client network and Network tier definitions. Follow these steps to configure the network tiers so that they are used as designed:

  1. Create a new Data center site and specify a set of IP addresses or a range of IP addresses corresponding to your data center.
  2. Modify a Client network tier definition.
    1. Remove the rule that excludes the All other site.
    2. Add a rule that excludes the Data center site.
  3. Modify a Network tier definition.
    1. Remove the rule that includes the All other site.
    2. Add a rule that includes the Data center site.

The Network tier now shows the data center traffic and the Client network tier now shows the traffic for the client sites.

Modifying a network tier

To modify a network tier:

  1. Select a tier in the Network tiers section.
  2. In the Rules for this tier section:
    • Click Add rule to define a new rule.
    • Select a rule and change its definition by selecting other region, area, or site in the designated fields.
    • Select a rule and click Delete rule to delete that rule from the tier definition.

Adding a rule based on sites

In the Rules for this tier section:

  1. Select Client network or Network tier.
  2. Select a region, area, or site to add it to the rule. Select Exclude to exclude a particular region, area, or site from a tier definition.

Citrix/WTS (presentation) tier

If you use presentation servers (such as Citrix or Windows Terminal Services) and have configured software services based on the ICA analyzer, the Citrix/WTS (presentation) tier will automatically be displayed on the Tiers report.

This tier presents traffic related to the ICA analyzer for real users only. You cannot modify its definition.

The Citrix/WTS (presentation) tier belongs to the Network tiers section because it is treated as an application delivery channel. For Citrix and Windows Terminal Services, the key metrics are network performance, server loss rate, or client RTT (not operations or operation time, as it is for the data center tiers).

We do not recommend creating another tier for Citrix. The default Citrix/WTS (presentation) tier guarantees that the measurements for your presentation servers are visible on the Tiers report.

Solution-specific tiers

Additional tiers may be available, depending on your configuration.

  1. If your NAM Server is configured to receive data from Enterprise Synthetic Agent Manager, the Synthetic tier automatically displays on the Tiers report. The Synthetic tier presents measurements for all transactions originating from the Enterprise Synthetic agents.

  2. If your NAM Server is configured to receive data from Dynatrace Performance Network, the Synthetic backbone tier automatically displays on the Tiers report. The Synthetic backbone tier presents measurements for all transactions originating from assigned DPN accounts.

  3. If you use WAN optimization, the Client optimized network tier automatically displays on the Tiers report. This tier shows data for optimized WAN links; you cannot view its definition rules.

    Note that the data for optimized WAN links includes traffic originated from real users as well as from synthetic agents.

  4. If you have configured sequence transactions on the NAM Probe and the NAM Server receives information about those transactions, the RUM sequence transactions tier automatically displays on the Tiers report. The RUM sequence transactions tier presents measurements for all sequence transactions originating from NAM Probes.

  5. If you have added the Dynatrace Application Monitoring Server and enabled the data feed, the RUM Browser tier automatically displays on the Tiers report. The RUM browser tier presents data originating from User Experience Management provided by the Dynatrace Application Monitoring Server.
