JENNIFER 5.4.0 Release Note
Release Date : 2018. 08. 31
Changes and Improvements
Added an unofficial option to limit the number of profiles stored in data server "jennifer.unofficial.limit.number.of.profiles.to.collect". By default, there is a limit of 10,000 profiles collected per transaction. If you want to change this limit, add the above-mentioned option in jennifer_data.sh(bat) file.
Profile collection performance improvement. If there are very many profiles in a transaction, the loss of transactions, profiles, and statistical information was improved when collecting them. The statistical data based on the profile was reduced to the default number of 10000 profiles that were collected and stored as before, lowering the probability of data loss.
Accept the @ character in SQL Bound parameter value - Microsoft SQL Server.
Prevent (-1) comparison events from being created when the matrix value of the comparison target does not exist.
Case sensitive when renaming URLs.
You can check the current system time zone information in the data server log
Memory consumption improvement when a profile contains a large number of remote calls.
Added options to avoid collecting when there are too many application-specific SQL or ExternalCalls. (Application SQL combination statistic collection option Jennifer.unofficial.enable.collect.application.sql.combination.statistic, application ExternalCall combination option Jennifer.unofficial.enable.collect.application.externalcall.combination.statistic)
Improved to collect Application, SQL, ExternalCall combination statistics in minutes

- Starting from Agent 5.4.0 minimum JDK support is JAVA 1.6(+). For JAVA 1.5 please use agent 5.3.3.x and below
- In order to maintain various compatibility and to support JAVA 9 (+) version, the agent contains 5 modules instead of 3 modules as previous versions (jennifer.jar, jennifer.impl, jennifer.rt, jennifer.jdk6, jennifer.jdk9)
- If you want to upgrade that version, you need to manually copy the base module and the newly added library.
When using JAVA 9 (+) version, the following functions are not supported:
- enable_datasource_trace = JAVA9(+) the option is automatically set to false.
- Analysis -> File -> Disk usage is not displayed.
When SQL is executed, the active service pop-up window does not display the currently used Connection name
Added an option to not collect transaction CPU information. (profile_transaction_cpu)
Setting the profile_transaction_cpu option prevents transactions and active services from collecting CPU information. It is an option to reduce the load in heavy load conditions.

Added option for Lambda method profile (enable_lambda)
