Filtering application servers

The first step to analyze application server diagnostics is to locate the application servers you want to analyze.

To pinpoint the relevant application servers, use one or more of the following filters:

Time filter
Summary filter
Column filters in the displayed table of transactions

To filter by a defined time range

When you open the Application Servers window, by default the window shows servers from which transactions were collected in the previous 15 minutes.

The macro unmigrated-inline-wiki-markup from Confluence is no longer available.

To filter by application server summaries

The summary filter enables you to quickly filter the application servers in the defined time range.

Click the relevant summary box to display all application servers or only application servers that have transactions with latency violations or errors.

Example

In the following example, click with Errors to list the application servers that have transactions with errors.

Summary filter example

Errors indicate application servers with transactions that returned an error code or an exception, which typically indicates an application availability issue.

Note

The Java version of BMC Application Diagnostics only counts as errors those requests that throw an exception from the entry point. It does not count HTTP errors.

To filter by column headings in the table of application servers

You can use filter boxes that are located under each column heading in the table of application servers. For details about the data in the columns, see Application-server-table-columns.

Filter the table entries in one of the following ways:

Filter columns with alphanumeric results by entering all or part of a string.
Only results that contain a match are displayed.
Filter columns with numeric results by entering a symbol for the mathematical relationship and a whole number. To change the current symbol, select it and enter one of the following valid symbols: <, =, >. For the Availability, Latency, and Errors columns, enter percentage values. In the Latency column, define the filter > 50 to display servers with transactions in which latency violations occurred in over 50% of the transactions.
Column filter example

You can also sort columns in ascending or descending order by clicking the column heading.

To view transactions relevant to your filtered application servers

Click Relevant Business Transactions to view the transactions relevant to your filtered settings, in the Business Transactions window.

Business transactions can provide further insight into the root cause of application server problems, because issues with the performance and availability of application servers might be impacted by an application and its transactions. By analyzing the transactions in the Business Transactions window, you can locate problematic transactions at the selected time, and possibly pinpoint the cause.

Note

Filters used in the Application Servers window are applied to the list of business transactions. For example, if you filter the list of servers according to a custom time range and then filtered the list of displayed servers by the name Production, only the business transactions that meet the criteria are displayed.

Where to go from here

To view a list of traces for a selected server, click a server name of interest in the table.
