| This plugin listens for plugin msgs and invokes jemalloc control | ||
| operations. | ||
|
|
||
| Installation | ||
| ============ | ||
|
|
||
| Add the following line to :file:`plugin.config`:: | ||
|
|
||
| memory_profile.so | ||
|
|
||
| In addition, |TS| must be able to read jemalloc configuration | ||
| information either through the ``JEMALLOC_CONF`` environment variable | ||
| or via the string sym linked to ``/etc/malloc.conf``. | ||
|
|
||
| For example, if the string below is in ``JEMALLOC_CONF`` or in the sym link string, it | ||
| enables profiling and indicates that the memory dump prefix is ``/tmp/jeprof``.:: | ||
|
|
||
| prof:true,prof_prefix:/tmp/jeprof | ||
|
|
||
| Details on configuration jemalloc options at `<http://jemalloc.net/jemalloc.3.html>`. | ||
| Changes to the configuration in ``JEMALLOC_CONF`` or ``/etc/malloc.conf`` require a process | ||
| restart to pick up. | ||
|
|
||
| Plugin Messages | ||
| =============== | ||
|
|
||
| The plugin responds to the following mesages sent via traffic_ctl. | ||
|
|
||
| Message Action | ||
| ========== =================================================================================== | ||
| activate Start jemalloc profiling. Useful if prof_active:false was in the configure string. | ||
|
|
||
| deactivate Stop jemalloc profiling. | ||
|
|
||
| dump If profiling is enabled and active, it will generate a profile dump file. | ||
|
|
||
| stats Print jemalloc statistics in traffic.out | ||
|
|
||
| The command below sends the stats message to the plugin causing the current statistics to be written to traffic.out:: | ||
|
|
||
| traffic_ctl plugin msg memory_profile stats | ||
|
|
||
| Example Usage | ||
| ============= | ||
|
|
||
| If your run time configuration string is:: | ||
|
|
||
| prof:true,prof_prefix:/tmp/jeprof:prof_active:false | ||
|
|
||
| |TS| has started without profile sampling started. Perhaps you didn't want to profile the start up phase of |TS|. To start | ||
| you need to send the activate message to the plugin:: | ||
|
|
||
| traffic_ctl plugin msg memory_profile activate | ||
|
|
||
| If your run time configuration string does not indicate that the profiling is not started (e.g. the prof_active field is missing or set to true), you do not | ||
| need to send the activate message. | ||
|
|
||
| After waiting sometime for |TS| to gather some memory allocation data, you can send the dump message:: | ||
|
|
||
| traffic_ctl plugin msg memory_profile dump | ||
|
|
||
| This will cause a file containing information about the current state of the |TS| memory allocation to be dumped in a file prefixed | ||
| by the value of prof_prefix. In this example, it would be something like ``/tmp/jeprof.1234.0.m0.heap``, where 1234 is the process id | ||
| and 0 is a running counter indicating how many dumps have been performed on this process. Each dump is independent of the others | ||
| and records the current stat of allocations since the profiling was activated. The dump file can be processed by jeprof | ||
| to get text output or graphs. Details of how to use jeprof are in the man pages or `<https://manpages.debian.org/unstable/libjemalloc-dev/jeprof.1.en.html>`. | ||
|
|
||
| You may want to send the dump message periodically to analyze how the |TS| memory allocation changes over time. This periodic dump can also be achieved by setting the | ||
| ``lg_prof_interval`` option in the run time configuration string. | ||
|
|
||
| If the profiling is taking a significating amount of processing time and affecting |TS| performance, send the deactivate message to turn off profiling.:: | ||
|
|
||
| traffic_ctl plugin msg memory_profile deactivate | ||
|
|
||
| Send the stats message to cause detailed jemalloc stats to be printed in traffic.out. These stats represent actvitiy since the start of the |TS| process.:: | ||
|
|
||
| traffic_ctl plugin msg memory_profile stats | ||
|
|
||
| Limitations | ||
| =========== | ||
|
|
||
| Currently the plugin only functions for systems compiled against jemalloc. | ||
| Perhaps in the future, it can be augmented to interact with other memory | ||
| allocation systems. | ||
