CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
# Sampling Query Profiler
Update sampling_query_profiler.md
2020-02-02 03:20:49 +00:00
ClickHouse runs sampling profiler that allows to analyze query execution. Using profiler you can find source code routines that used the most frequently during a query execution. You can trace CPU time and wall-clock time spent including idle time.
CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
To use profiler:
CLICKHOUSEDOCS-272: More info.
2020-01-16 16:53:56 +00:00
- Setup the [trace_log](../server_settings/settings.md#server_settings-trace_log) section of the server configuration.
CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
Update sampling_query_profiler.md
2020-02-02 03:20:49 +00:00
This section configures the [trace_log](../system_tables.md#system_tables-trace_log) system table containing the results of the profiler functioning. It is configured by default. Remember that data in this table is valid only for running server. After the server restart, ClickHouse doesn't clean up the table and all the stored virtual memory address may become invalid.
CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
Update sampling_query_profiler.md
2020-02-02 03:20:49 +00:00
- Setup the [query_profiler_cpu_time_period_ns](../settings/settings.md#query_profiler_cpu_time_period_ns) or [query_profiler_real_time_period_ns](../settings/settings.md#query_profiler_real_time_period_ns) settings. Both settings can be used simultaneously.
CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
These settings allow you to configure profiler timers. As these are the session settings, you can get different sampling frequency for the whole server, individual users or user profiles, for your interactive session, and for each individual query.
Update sampling_query_profiler.md
2020-02-02 03:20:49 +00:00
Default sampling frequency is one sample per second and both CPU and real timers are enabled. This frequency allows to collect enough information about ClickHouse cluster. At the same time, working with this frequency, profiler doesn't affect ClickHouse server's performance. If you need to profile each individual query try to use higher sampling frequency.

CLICKHOUSEDOCS-272: Furher edditing.
2020-01-16 07:55:18 +00:00
To analyze the `trace_log` system table:
CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
CLICKHOUSEDOCS-272: More info.
2020-01-16 16:53:56 +00:00
- Install the `clickhouse-common-static-dbg` package. See [Install from DEB Packages](../../getting_started/install.md#install-from-deb-packages).
CLICKHOUSEDOCS-272: Ready for review.
2020-01-24 05:48:49 +00:00
- Allow introspection functions by the [allow_introspection_functions](../settings/settings.md#settings-allow_introspection_functions) setting.
CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
For security reasons introspection functions are disabled by default.
CLICKHOUSEDOCS-272: Ready for review.
2020-01-24 05:48:49 +00:00
- Use the `addressToLine`, `addressToSymbol` and `demangle` [introspection functions](../../query_language/functions/introspection.md) to get function names and their positions in ClickHouse code. To get a profile for some query, you need to aggregate data from the `trace_log` table. You can aggregate data by individual functions or by the whole stack traces.
CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
Update sampling_query_profiler.md
2020-02-02 03:20:49 +00:00
If you need to visualize `trace_log` info, try [flamegraph](../../interfaces/third-party/gui/#clickhouse-flamegraph) and [speedscope](https://github.com/laplab/clickhouse-speedscope).

## Example
CLICKHOUSEDOCS-272: Ready for review.
2020-01-24 05:48:49 +00:00
In this example we:
Update sampling_query_profiler.md
2020-02-02 03:20:49 +00:00
- Filtering `trace_log` data by a query identifier and current date.
- Aggregating by stack trace.
- Using introspection functions, we will get a report of:
CLICKHOUSEDOCS-272: Ready for review.
2020-01-24 05:48:49 +00:00
- Names of symbols and corresponding source code functions.
Update sampling_query_profiler.md
2020-02-02 03:20:49 +00:00
- Source code locations of these functions.
