Environment Variables at JVM Start Table

This table lists the key-value pairs for the environment variables in use when the JVM was started. The left column on the table lists the key and the right column shows the value for that key.

This table has a filtering mechanism that allows you narrow the information shown in a table by specifying a column and a value in that column by which to filter the results. This is helpful if you want to limit the results, for example, to just those environment variables containing information about the processor.

To filter a column:

  1. Right-click the Filter Column to open its menu and select the column you want to filter on, for example Value.

    The column name appears in the Filter Column field.

  2. In the adjacent text box, enter the string for which you want to filter.

    Normally, to lessen the impact on performance, matching is done using only simple Kleene star wildcards. A star (*) will match zero or more occurrences of anything; for example:

    8* will match anything beginning with 8. *es will match anything ending with es.

    You can also match using regular expressions; however, resolution can take much longer with complex expressions and large amounts of data; for example:

    regexp:(YC|Young Collect).* will match anything starting with YC or Young Collect, such as YC Promotion Failed, Young Collection and Young Collector Nursery Snapshot.

    You can also build logical expressions for columns with numerical values. For instance, for a column with counts, such as the one in Memory/allocation Allocation by Class table, the expression > 100 && < 500 will filter out the classes with more than 100 but less than 500 events.

    The filter text entry field is case sensitive.
