Transactions

Note

For more information about transaction, see the following. For example, see the following on the transaction analysis guide in case of using the hitmap.

Transaction tracing

whatap.profile_step_normal_count Int

Default 1000

Set the maximum step count for tracing transactions.
whatap.profile_step_max_count Int

Default 1024

Set the maximum number of trace steps. If the number of collected trace steps exceeds this value, all steps collected later are ignored.
whatap.profile_step_heavy_count Int

Default 1000

If the collection number of basic steps is exceeded, only the steps whose execution time exceeds profile_step_heavy_time are collected. Set the count of the step that can be collected. In case of default settings, if profile_step_normal_count is 800, up to 200 steps are collected.
whatap.profile_step_heavy_time Millisecond

Default 100

Set the criterion of heavy steps. If the execution time is greater than the set value and profile_step_normal_count is exceeded, recording is made within profile_step_heavy_count.
whatap.profile_basetime Millisecond

Default 500

Transaction trace data is not collected if a transaction is terminated within the set value. The first URL called in every 5 minutes and the erroneous profile data are collected.
whatap.query_string_enabled Boolean

Default false

It enables the function to collect query strings of the transaction URL together. It is applied to only the URLs registered in whatap.query_string_urls.
whatap.query_string_urls String

Register URLs to collect query strings from every transaction.
whatap.whatap.profile_compile_file_enabled Boolean

Default false

It sets whether or not to trace the compile_file and compile_string functions. The compile_file and compile_string functions (PHP internal functions) are compiled before executing the scripts. You can check the compile times for main, include, require, and autoload scripts, the script file paths, and the execution times.

Note

The setting is applied after Apache and PHP-FPM have been restarted.

whatap.profile_compile_file_basetime Millisecond

Default 200

Set the criterion of the execution time. Data is collected only when execution has been made while the set time was exceeded.

Caution
If whatap.profile_compile_file_basetime is set too small, excessive collection may overload the server.

Note

The setting is applied after Apache and PHP-FPM have been restarted.

whatap.profile_method_enabled Boolean

Default true

The user functions whose execution time exceeds the set value (default is 1 second) of the profile_method_time can be found in the transaction details.

Note

The setting is applied after Apache and PHP-FPM have been restarted.

whatap.profile_method_time Milliseconds

Default 1000

Set the execution time for collected functions with the whatap.profile_method_enabled setting.

Note

The setting is applied after Apache and PHP-FPM have been restarted.

whatap.profile_method_stack_enabled Boolean

Default false

You can check the stack information of the user functions in transaction details.

Note

The setting is applied after Apache and PHP-FPM have been restarted.

whatap.profile_internal_method_enabled Boolean

Default true

Set whether or not to trace the PHP internal function. Tracing is performed only when the function takes more than the whatap.profile_internal_method_time setting (Default: 1 second).

Note

The setting is applied after Apache and PHP-FPM have been restarted.

whatap.profile_internal_method_time Milliseconds

Default 1000

Set the execution time of the function when tracing PHP internal functions (whatap.profile_internal_method_enabled).

Note

The setting is applied after Apache and PHP-FPM have been restarted.

whatap.profile_internal_method_param_enabled Milliseconds

Default 1000

Functional parameters are additionally collected when tracing PHP internal functions (whatap.profile_internal_method_enabled).

Note

The setting is applied after Apache and PHP-FPM have been restarted.

whatap.net_udp_flush_start Boolean

Default true

If the value is false, the transaction start time is not collected.

Note
Because the start point is not collected, it can be reflected a little later in the active transaction data that counts the number of active transactions. Active status is recorded normally.
whatap.net_udp_profile_basetime_enabled Boolean

Default false

If the value is true, the trace data for transactions faster than the set response time is not collected.
whatap.net_udp_profile_basetime Miliseconds

Default false

Set the response time for transactions excluding the trace data collection.

Note
Because the trace data is not collected, it is not applied to the statistics such as SQL and HTTPC.
whatap.net_udp_trace_ignoretime_enabled Boolean

Default false

If the value is true, the transactions and trace data that take the set response time are not collected.
whatap.net_udp_trace_ignoretime Miliseconds

Default 30

Set the response time for transactions excluding the transaction and trace data collection.
whatap.shm_tx_counter_enable Boolean

Default false

If the value is true, when transaction data collection is excluded by setting whatap.net_udp_trace_ignoretime_enabled, the data for excluded transactions is reflected in the statistics when the TPS, average response time, and Apdex metrics are collected from the shared memory.

Note
Transactions that have not been collected are normally reflected in TPS, average response time, and Apdex metrics, but they are not reflected in other statistical data.
whatap.split_profile_enabled Boolean

Default false

More profiles are collected by separating a certain amount of profiles into virtual transactions. They are divided into multiple transaction lists.
Note
If set at the same time, the priorities are as follows:
1. split
2. large
3. circular
whatap.large_profile_enabled Boolean

Default false

By sending split and compressed profiles, you can collect more profiles without increasing memory usage.
Note
- We can collect up to 10,000 profiles (steps). For more data, it is recommended to use the whatap.split_profile_enabled option.
- If set at the same time, the priorities are as follows:
  1. split
  2. large
  3. circular
whatap.circular_profile_enabled Boolean

Default false

The last 1024 profiling data is collected.
Note
If set at the same time, the priorities are as follows:
1. split
2. large
3. circular
whatap.profile_zip_enabled Boolean

Default true

Compressed profiles are transmitted. The default value is true.

HTTP transaction tracing

whatap.trace_normalize_enabled Boolean

Default true

It enables the function to convert and normalize transaction URLs.
whatap.trace_normalize_urls String

Set the target URL to transform and normalize. It deletes the path parameter by transforming the call URL patterns.

Note
For example, if it is set as /a/{v}/b, the called transaction URLs are transformed to the /a/{v}/b format. To register multiple items, comma (,) is used as the delimiter.
whatap.trace_ignore_url_set String

Default 0

If a specific URL is set, the corresponding transactions are excluded from tracing. The set URLs are not displayed in the transaction list because they do not collect transaction data. Set URLs to exclude from transaction tracing. To set multiple items, use comma (,) as the delimiter.
whatap.trace_ignore_url_prefix String

Default 0

It sets URL prefixes to exclude from the transaction tracing.
whatap.profile_http_header_enabled Boolean

Default false

It is used to record the HTTP headers in the trace history.
whatap.profile_http_header_ignore_keys String

Default host,accept,user-agent,referer, accept-language, connection

It is used to record HTTP headers in the profile details. The set HTTP header names are excluded from collection, and they are marked with "#."
whatap.profile_http_parameter_enabled Boolean

Default false

It is used to record HTTP parameters in the trace history. The parameters can be viewed by entering a separate security key.

It collects the text names and values among Get and Post parameters. Parameters are collected up to 40 (Get 20, Post 20) and the parameter names and values are collected up to 256 bytes.

Parameter data is transferred after being encrypted separately, and can be viewed by decrypting with the key in /usr/whatap/php/paramkey.txt of the application server.
whatap.profile_http_parameter_url_prefix String

Default /

It is used to define the prefix of URL to record HTTP parameters in the trace details.
whatap.profile_http_host_enabled Boolean

Default false

The transation host is output. If the value is false, only the URI is recorded in the URL of a transaction. If the value is true, the output has the format of /xxx.aaa.com/URL.

whatap.ignore_http_method String

Default Empty

Transactions requested by the specified HTTP method are not collected. To set multiple items, use comma (,) as the delimiter.

whatap.ini
# e.g. tracing the transactions whose http_method is OPTIONS or HEAD
ignore_http_method=PATCH,TRACE

# e.g. ignoring the transactions whose http_method is OPTIONS or HEAD
ignore_http_method=OPTIONS,HEAD

whatap.biz_exceptions String

Default Empty

Set a specific error or exception as business exception. It is not recorded as an error in the hitmap but collected in the statistics. It is applied the same as the error class name that is collected. Multiple items can be registered using comma (,) as the delimiter.
whatap.ignore_exceptions String

The errors of the registered exceptions are ignored.

In case of exception, if the custom exception class is not defined, data is collected as exception by default. To exclude specific exceptions, define the custom exception class and then set the name of exception.

Transaction tracing

whatap.trace_active_transaction_slow_time Millisecond

Default 3000

In the active transaction arc equalizer graph on the dashboard that checks collected data, specify the criteria for the transaction response time that can be recorded as a slow section. If the transaction response time exceeds the set time, the number of slow active transactions is included.
whatap.trace_active_transaction_very_slow_time Millisecond

Default 8000
whatap.trace_active_transaction_lost_time Millisecond

Default 30000

If a transaction does not end within the timeout period (5 minutes), no further transaction data is collected. You can see Lost Connection in the transaction trace information.
whatap.trace_useragent_enabled Boolean

Default false

If the value is true, the user agent data for transactions is collected.
whatap.trace_referer_enabled Boolean

Default false

If the value is true, the referer data for transactions is collected.

Multiple transaction trace

whatap.mtrace_enabled Boolean

Default false

It sets whether or not to use the multi-transaction tracing (MTID). By tracing the MTID, you can check the calls between all the registered applications.
whatap.mtrace_rate Percentage

Default 10

This option sets the issuance rate of the MTID (Multi Transaction ID) issued when the first transaction occurs.
whatap.mtrace_poid_key String

Default x-wtap-po

Set the key name to deliver the caller project information to for MTID tracing.
whatap.mtrace_caller_key String

Default x-wtap-mst

whatap.mtrace_callee_key String

Default x-wtap-tx

Set the callee key name to be used for MTID tracing.
whatap.mtrace_send_url_length Int

Default 80
