CLICKHOUSEDOCS-272: The first draft for sampling query profiler.
2019-12-26 15:00:00 +00:00
# Sampling Query Profiler
ClickHouse runs sampling profiler that allows to analyse 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.
To use profiler:
CLICKHOUSEDOCS-272: Furher edditing.
2020-01-16 07:55:18 +00:00
- Setup the [trace_log][../server_settings/settings.md#server_settings-trace_log] section of the server configuration.

2020-01-16 07:55:18 +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.

2020-01-16 07:55:18 +00:00
- Setup the [query_profiler_cpu_time_period_ns](../settings/settings.md#query_profiler_cpu_time_period_ns) and [query_profiler_real_time_period_ns](../settings/settings.md#query_profiler_real_time_period_ns) settings.

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.

2020-01-16 07:55:18 +00:00
Default sampling frequency is one sample per second. This frequency allows to catch enough precise information about ClickHouse servers operating. Working with this frequency, profiler doesn't affect ClickHouse server's efficiency. If you need to profile each individual query try to use higher sampling frequency.

- Install the `clickhouse-common-static-dbg` package.

- Allow introspection functions.
For security reasons introspection functions are disabled by default.
- Use the addressToLine, addressToSymbol and demangle introspection functions to get function names and their positions in ClickHouse code.
To get query profile, you need to aggregate the data from trace_log. You can aggregate by individual functions or by the whole stack traces.
There is an instrument that allows to visualize trace_log info as a [flamegraph](../../interfaces/third-party/gui/#clickhouse-flamegraph).
## Example
In this example we filter trace_log data by query identifier (query_id column) and the current date, then counting the same traces and for each trace getting representation which consists of the symbol name and corresponding source code function name and a position of this function in a code (a file name and a line number). Which we get by addressToSymbol, damangle и addressToLine functions.
```sql
SELECT
count(),
arrayStringConcat(arrayMap(x -> concat(demangle(addressToSymbol(x)), '\n ', addressToLine(x)), trace), '\n') AS sym
FROM system.trace_log
WHERE (query_id = 'ebca3574-ad0a-400a-9cbc-dca382f5998c') AND (event_date = today())
GROUP BY trace
ORDER BY count() DESC
LIMIT 10
```
